In order to improve the treatment efficiency of solid waste, a single - shaft crusher is usually used to perform crushing pretreatment on solid waste to facilitate the subsequent treatment process. The single - shaft crusher is provided with a crushing space and a crushing main shaft located in the crushing space. In order to improve the efficiency of treating solid waste, the single - shaft crusher is equipped with a pressure - feeding mechanism, and the pressure - feeding mechanism is used to push the solid waste towards the crushing main shaft of the single - shaft crusher.

[0003] In the prior art, a general pressure - feeding mechanism includes a pushing plate and a guide rail. The pushing plate moves horizontally along the guide rail to push the solid waste towards the crushing main shaft. However, by using the method of the pushing plate moving horizontally along the guide rail, the stroke of the pushing plate is long, resulting in a relatively large overall volume of the single - shaft crusher and being inconvenient for transportation. Currently, some external arc - type single - shaft crushers have emerged in the market. They set the pressure - feeding mechanism outside the crushing space and use the pushing plate to perform an arc - shaped movement and extend into the crushing space for pressure - feeding to reduce friction and volume. However, the structure with the moving mechanism outside has safety problems in use, and the pushing plate frequently enters and exits the crushing space, resulting in the problems that the pushing plate is likely to carry out waste and a large amount of dust from the crushing space.

[0028] As Figure 1 and Figure 2As shown in the figure, a single-shaft crusher with an internal pressure-feeding mechanism according to an embodiment of the present invention includes: a machine body 100 provided with a crushing space 110; a crushing main shaft 200 disposed in the crushing space 110; a pushing plate 300 located in the crushing space 110; and a driving mechanism disposed on the machine body 100. The crushing space 110 is provided with an arc surface portion 111. The driving mechanism is connected to the pushing plate 300, and the driving mechanism can drive the pushing plate 300 to move along the arc surface portion 111.

[0029] The pushing plate 300 is disposed in the crushing space 110 and the crushing space 110 is provided with an arc surface portion 111. The driving mechanism drives the pushing plate 300 to reciprocate along the arc surface portion 111 to push the solid waste towards the crushing main shaft 200. In this way, the pressure-feeding process is completed in the crushing space 110. The pushing plate 300 does not need to leave the crushing space 110, which can prevent the pushing plate 300 from taking the waste or dust out of the crushing space 110. At the same time, the reciprocating arc movement of the pushing plate 300 does not require a long linear stroke, which is beneficial to reducing the overall volume of the single-shaft crusher.

[0030] Refer to Figure 2 and Figure 3 , in some embodiments of the present invention, the pushing plate 300 tapers from the end facing the crushing main shaft 200 towards the end away from the crushing main shaft 200.

[0031] By tapering the end of the pushing plate 300 away from the crushing main shaft 200, when the pushing plate 300 moves upward along the arc surface portion 111 during the reciprocating arc movement, the driving of the waste upward by the pushing plate 300 is reduced, which is beneficial to further preventing the waste from flying out of the crushing space 110. Preferably, the end of the pushing plate 300 away from the crushing main shaft 200 tapers to a pointed shape. In addition, the end of the pushing plate 300 close to the crushing main shaft 200 is wider, which is beneficial to the pushing plate 300 to push the waste towards the crushing main shaft 200 when moving downward along the arc surface portion 111, achieving the effect of pressure-feeding and improving the efficiency of waste treatment.

[0032] When the single-shaft crusher is working, generally a transmission mechanism such as a conveyor belt is used to transport the waste to the crushing space 110. In order to ensure that the waste can fall into the crushing space 110, the waste will fall from the center or the midline position of the crushing space 110. In this way, it often causes a large amount of waste to be processed at the middle position of the crushing main shaft 200, while less pressure-feeding is applied at both ends of the crushing main shaft 200, that is, there is a problem of uneven waste treatment amount at each part of the crushing main shaft 200, which easily leads to faster wear of the middle part of the crushing main shaft 200 and insufficient use of both ends.

[0033] To solve the above problems, refer to Figures 1 to 3, in some embodiments of the present invention, a material distributing portion 310 is provided on the pushing plate 300. During the arcuate reciprocating movement of the pushing plate 300, the waste is dispersed by the material distributing portion 310, so that the waste can be evenly pushed towards the crushing main shaft 200, enabling each part of the crushing main shaft 200 to evenly process the amount of waste, which is beneficial to making full use of the two end portions of the crushing main shaft 200, improving the efficiency of waste treatment, and at the same time extending the service life of the crushing main shaft 200.

[0034] Refer to Figure 3 , in some embodiments of the present invention, the material distributing portion 310 is in the shape of a triangular pyramid. The bottom surface of the triangular pyramid is connected to the pushing plate 300. The bottom surface of the triangular pyramid is an isosceles triangle, and the apex angle of the isosceles triangle faces away from the crushing main shaft 200.

[0035] The material distributing portion 310 is in the shape of a triangular pyramid and the apex angle of the isosceles triangle at the bottom surface faces away from the crushing main shaft 200, that is, the triangular pyramid gradually becomes wider and higher in the direction approaching the crushing main shaft 200. When the pushing plate 300 moves upward along the arc surface portion 111, the triangular pyramid can separate and push the waste to both sides, thereby achieving the effect of evenly dispersing the waste. The structure is simple and easy to implement, and the shape of the triangular pyramid can reduce the influence of pushing the waste upward. The material distributing portion 310 can also be in other implementation forms such as a conical shape, a double triangular pyramid shape, or a quadrangular prism shape that can disperse the waste.

[0036] Refer to Figure 2 , Figure 5 and Figure 6 , in some embodiments of the present invention, a fitting gap is left between the pushing plate 300 and the arc surface portion 111. An upper baffle plate 320 is provided on the end surface of the pushing plate 300 away from the crushing main shaft 200, and a lower baffle plate 330 is provided on the end surface of the pushing plate 300 close to the crushing main shaft 200.

[0037] In order to reduce the friction between the pushing plate 300 and the arc surface portion 111, a fitting gap is left between the pushing plate 300 and the arc surface portion 111, so that the resistance received by the pushing plate 300 during the arcuate reciprocating movement is smaller. At the same time, in order to prevent the waste from entering the fitting gap and causing an increase in resistance, an upper baffle plate 320 and a lower baffle plate 330 are provided on the pushing plate 300 to prevent foreign objects from entering the fitting gap. At the same time, the upper baffle plate 320 and the lower baffle plate 330 can scrape off the objects adhering to the arc portion, which is beneficial to improving the stability and reliability of the work.

[0038] Refer to Figure 3 , in some embodiments of the present invention, a plurality of toothed plates 340 are provided on the end surface of the pushing plate 300 facing the crushing main shaft 200.

[0039] When the pushing plate 300 pushes the waste towards the crushing main shaft 200, the toothed plate 340 can effectively prevent the material from slipping, which is beneficial for the crushing main shaft 200 to process the waste, improve work efficiency, and the toothed plate 340 is also beneficial for preventing the waste from adhering to the pushing plate 300.

[0040] Referring to Figures 1 to 4 , in some embodiments of the present invention, the driving mechanism includes an internal swing arm 410, a swing arm shaft 420, and a driving member 430. One end of the internal swing arm 410 is connected to the pushing plate 300, the other end of the internal swing arm 410 is connected to the swing arm shaft 420, the swing arm shaft 420 is movably connected to the machine body 100 and the swing arm shaft 420 is located at the center of the arc of the arc surface 111, and the driving member 430 is connected to the swing arm shaft 420.

[0041] The internal swing arm 410 rotates around the swing arm shaft 420, and the swing arm shaft 420 is located at the center of the arc of the arc surface 111. When the internal swing arm 410 drives the pushing plate 300, the pushing plate 300 can move along the arc surface 111 and leave a fitting gap. The driving member 430 is connected to the swing arm shaft 420 to drive the internal swing arm 410 to drive the pushing plate 300, and the arc-shaped reciprocating motion of the pushing plate 300 is realized by this structure, with a simple structure and easy to implement.

[0042] Referring to Figures 1 to 4 , in some embodiments of the present invention, an external swing arm 440 is further included. The driving member 430 is a power cylinder. One end of the external swing arm 440 is connected to the swing arm shaft 420, and the other end of the external swing arm 440 is connected to the power cylinder.

[0043] The power cylinder drives the external swing arm 440 and then drives the swing arm shaft 420. The arc-shaped reciprocating motion effect of the pushing plate 300 can be conveniently realized through the telescopic motion of the power cylinder, with a simple structure and easy to implement. The power cylinder can be an air cylinder, a hydraulic cylinder, an electric cylinder, etc.

[0044] In some embodiments, the driving member 430 can also be implemented by a motor, directly driving the swing arm shaft 420 to rotate without the external swing arm 440.

[0045] Referring to Figure 4 , in some embodiments of the present invention, a swing arm bearing seat 450 and a swing arm bearing 460 are further included. The swing arm bearing seat 450 is connected to the machine body 100, the swing arm bearing 460 is arranged on the swing arm bearing seat 450, and the swing arm shaft 420 is connected to the swing arm bearing 460.

[0046] The swing arm shaft 420 is connected to the machine body 100 through the swing arm bearing 460 and the swing arm bearing seat 450. When the swing arm shaft 420 rotates, the swing arm bearing 460 can effectively reduce the rotation resistance, make the swing arm shaft 420 easier to rotate, be beneficial for reducing the energy loss caused by friction, and improving the energy utilization rate.

[0047] Reference Figures 1 to 3 , in some embodiments of the present invention, the length of the external swing arm 440 is less than the length of the internal swing arm 410.

[0048] Through the structure where the length of the external swing arm 440 is less than the length of the internal swing arm 410, the effect of amplifying the driving stroke and speed of the power cylinder can be achieved, which is beneficial to improving work efficiency.

[0049] Of course, the present invention is not limited to the above embodiments. Those skilled in the art can make equivalent deformations or substitutions without departing from the spirit of the present invention, and these equivalent variations or substitutions are all included within the scope defined by the claims of this application.
