1. Field of the Invention
The present invention relates to a cleaning machine, and more particularly to a dry-type cleaning machine.
2. Description of the Prior Art
Usually, in a process of recycling waste materials (for example, plastic, rubber or cloth), the waste materials are put in a crusher to be crushed, and then a cutter stirs and cuts the waste materials with a liquid as an auxiliary so as to wash away dirt on the waste materials. Therefore, crushed aggregates after the crushing process are cleaner. This type of cleaning machines are disclosed in TW237695, TWM409934 and TWM411293.
However, with the conventional cleaning machine, a clean liquid is essential during a process of cleaning the waste materials, so it is water-wasting and costly to use the conventional cleaning machine to clean the waste materials. Besides, the liquid used to clean the waste materials is dirty, so the liquid used needs to be processed before being discharged. In addition, the liquid used may leak out of the cleaning machine and make the work environment dirty, and if the liquid used is not processed before being discharged, the liquid used may pollute the environment.
The present invention has arisen to mitigate and/or obviate the afore-described disadvantages.
The major object of the present invention is to provide a dry-type cleaning machine. On the premise of being environment-friendly, a cleaning machine in which no liquid is needed is designed to save water and cost. In addition, dirt is gathered via a negative pressure system to prevent air and water pollution and to create a better work environment.
To achieve the above and other objects, a dry-type cleaning machine is provided, including a negative pressure unit, a first dust gathering unit and a barrel body. The first dust gathering unit is formed with a first dust sucking passage communicated with the negative pressure unit. The barrel body has a receiving space communicated with the first dust sucking passage, a feeding inlet for entering of an material to be sieved, a discharging portion, a rotary assembly arranged in the receiving space and a sieve layer. The material to be sieved includes mixed crushed aggregates and dirt. The sieve layer is arranged between the rotary assembly and the first dust sucking passage, and the rotary assembly is driven by a power source to stir the material to be sieved continuously. The feeding inlet is communicated with the first dust sucking passage through the receiving space and the sieve layer to form a negative pressure passage. The sieve layer allows the dirt to pass therethrough and enter the first dust sucking passage, and the crushed aggregates pass through the discharging portion and are discharged out of the receiving space.
The present invention will become more obvious from the following description when taken in connection with the accompanying drawings, which show, for purpose of illustrations only, the preferred embodiment(s) in accordance with the present invention.
The present invention will be clearer from the following description when viewed together with the accompanying drawings, which show, for purpose of illustrations only, the preferred embodiment in accordance with the present invention.

The sieve layer 47 allows the dirt 62 to pass therethrough and enter the first dust sucking passage 31, and the crushed aggregates 61 pass through the discharging portion 45 and are discharged out of the receiving space 43.
Specifically, the barrel body 4 is communicated with the negative pressure unit 2, so there is a pressure difference between the receiving space 43 and outside.
The pressure difference allows an opening of the feeding inlet 44 to produce a sucking force inward. That is, the feeding inlet 44, the receiving space 43 and the sieve layer 47 form the negative pressure passage 48 to suck the dirt 62 through negative pressure so as to prevent the dirt 62 from polluting surroundings. In the receiving space 43, the material to be sieved 6 is stirred and rolled continuously by the rotary assembly 46, so the dirt 62 and the crushed aggregates 61 are separated. Because each sieve aperture of the sieve layer 47 has a fixed and predetermined radial dimension, the dirt 62 in smaller radial dimension can pass through the sieve layer 47 and be sucked into the first dust sucking passage 31.

Because the material to be sieved 6 is influenced by gravity and negative pressure suction, the material to be sieved 6 accumulates in a lower portion of the receiving space 43. Preferably, an extension direction of the barrel body 4 is parallel to a ground on which the dry-type cleaning machine 1 is set, the lower portion of the receiving space 43 has greater space to carry the material to be sieved 6, a circumferential side of the barrel body 4 facing the ground on which the dry-type cleaning machine 1 is set extends downward to form at least one gathering portion 412, each gathering portion 412 is substantially funnel-shaped, the first dust sucking passage 31 is connected with each gathering portion 412, and each funnel-shaped gathering portion 412 allows the dirt 62 to roll into the first dust sucking passage 31 and prevents the dirt 62 from blocking the first dust sucking passage 31. In this embodiment, the barrel body 4 has two the gathering portions 412, and the two gathering portions 412 are communicated with the negative pressure unit 2 through the first dust sucking passage 31 respectively. It is understandable that one of the gathering portions 412 may be communicated with another said negative pressure unit 2 to increase the force of negative pressure suction. Preferably, the first dust gathering unit 3 is further formed with a dust gathering barrel 32 which is communicated with the first dust sucking passage 31 and the negative pressure unit 2. The dirt 62 which passes through the sieve layer 47 and enters the first dust sucking passage 31 can be kept in the dust gathering barrel 32, so the dirt 62 can be processed solely and prevented from influencing functioning of the negative pressure unit 2.
However, a connection of the barrel body 4 and the first dust sucking passage 31 is not limited. Please further refer to

Given the above, the dry-type cleaning machine use negative pressure to create pressure difference between the receiving space of the barrel body and outside so as to suck the material to be sieved into the receiving space accurately. If the dry-type cleaning machine is assembled to a discharging opening of a crusher, the dirt in the material to be sieved can be prevented from polluting the surroundings.
In addition, each fan leaf of the rotary assembly is a blade, and the blades stir the material to be sieved to separate the dirt from the crushed aggregates and make the dirt smaller to be sucked into the first dust sucking passage. The dirt is gathered in the dust gathering barrel.
In addition, the feeding inlet may further cooperate with a delivery platform to form a suction-selecting unit to sieve out the material to be sieved from the mixed materials and to suck the material to be sieved into the negative pressure passage. A bottom portion of the barrel body may be funnel-shaped to keep the dirt rolling and to prevent the dirt from accumulating on the sieve layer. Furthermore, the bottom portion of the barrel body may be further formed with the carrying portion for carrying the dirt which is heavier.
While we have shown and described various embodiments in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
