As shown in fig. 1 and 2, a single-shaft crusher with a built-in swaging mechanism according to an embodiment of the present invention includes: a body 100 provided with a crushing space 110; a crushing main shaft 200 disposed in the crushing space 110; a pusher plate 300 located within the crushing space 110; and the driving mechanism is arranged on the machine body 100, the crushing space 110 is provided with an arc surface part 111, the driving mechanism is connected with the material pushing plate 300, and the driving mechanism can drive the material pushing plate 300 to move along the arc surface part 111.

The scraping wings 300 are arranged in the crushing space 110, the arc surface portion 111 is arranged in the crushing space 110, the driving mechanism drives the scraping wings 300 to reciprocate along the arc surface portion 111 so as to push solid waste to the crushing main shaft 200, the material pressing process is completed in the crushing space 110 in this way, the scraping wings 300 do not need to leave the crushing space 110, the scraping wings 300 can be prevented from bringing the waste or dust away from the crushing space 110, meanwhile, the scraping wings 300 do not need to have long linear strokes in an arc reciprocating motion mode, and the whole volume of the single-shaft crusher is favorably reduced.

Referring to fig. 2 and 3, in some embodiments of the invention, the stripper plate 300 narrows from an end towards the crushing main shaft 200 to an end away from the crushing main shaft 200.

By narrowing the end of the material pushing plate 300 away from the crushing main shaft 200, the material pushing plate 300 is prevented from driving the waste to move upwards when moving upwards along the arc surface part 111 in the arc reciprocating motion process, which is beneficial to further preventing the waste from flying away from the crushing space 110. Preferably, the end of the ejector plate 300 remote from the crushing main shaft 200 narrows to a tip shape. In addition, one end of the material pushing plate 300 close to the crushing main shaft 200 is wider, so that the material pushing plate 300 is beneficial to pushing the waste to lean against the crushing main shaft 200 when moving downwards along the arc-shaped surface part 111, the material pressing effect is realized, and the waste treatment efficiency is improved.

When the single-shaft crusher works, generally, a conveying mechanism such as a conveying belt is used for conveying wastes to the crushing space 110, and in order to ensure that the wastes can fall into the crushing space 110, the wastes can fall from the center or the middle line of the crushing space 110, and this way can often cause that the middle position of the crushing main shaft 200 needs to process a lot of wastes, and the pressing materials at two ends of the crushing main shaft 200 are less, namely, the problem that the amount of the wastes processed at each part of the crushing main shaft 200 is not uniform exists, which easily causes that the middle part of the crushing main shaft 200 is abraded quickly and the two ends are used insufficiently.

In order to solve the above problem, referring to fig. 1 to 3, in some embodiments of the present invention, a material distributing portion 310 is provided on the material pushing plate 300. In the arc-shaped reciprocating motion process of the material pushing plate 300, the waste is dispersed by the material distributing part 310, so that the waste can be uniformly pushed to the crushing main shaft 200, the quantity of the waste can be uniformly treated by each part of the crushing main shaft 200, the positions of the two end parts of the crushing main shaft 200 can be fully used, the waste treatment efficiency is improved, and the service life of the crushing main shaft 200 is prolonged.

Referring to fig. 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 material pushing plate 300, the bottom surface of the triangular pyramid is an isosceles triangle, and the vertex angle of the isosceles triangle faces away from the crushing main shaft 200.

Divide material portion 310 to be three arris pyramids and the isosceles triangle apex angle orientation of bottom surface keeps away from broken main shaft 200's direction, and three arris awl widens gradually and increases to the direction of being close to broken main shaft 200 promptly, and when scraping wings 300 shifts up along cambered surface portion 111, three arris awl can separately push the discarded object to both sides to this realizes the effect of the even discarded object of dispersion, and simple structure realizes easily, and the shape of three arris can reduce the influence that promotes the discarded object and shift up. The separating portion 310 may be in the form of a cone, a triangular pyramid, a quadrangular prism, or other embodiments capable of dispersing waste.

Referring to fig. 2, 5 and 6, in some embodiments of the present invention, a fit gap is left between the material pushing plate 300 and the arc surface 111, the material pushing plate 300 is provided with an upper material blocking plate 320 on an end surface far away from the crushing main shaft 200, and the material pushing plate 300 is provided with a lower material blocking plate 330 on an end surface near the crushing main shaft 200.

In order to reduce the friction between the material pushing plate 300 and the arc-shaped surface portion 111, a fit clearance is left between the material pushing plate 300 and the arc-shaped surface portion 111, so that the resistance of the material pushing plate 300 in the process of performing the arc-shaped reciprocating motion is smaller. Meanwhile, in order to avoid the increase of resistance caused by the fact that the waste enters the fit clearance, the upper baffle plate 320 and the lower baffle plate 330 are arranged on the material pushing plate 300, so that foreign matters are prevented from entering the fit clearance, and meanwhile, the upper baffle plate 320 and the lower baffle plate 330 can scrape off the adhered objects on the arc-shaped part, thereby being beneficial to improving the stability and the reliability of work.

Referring to fig. 3, in some embodiments of the invention, the stripper plate 300 is provided with a number of tooth plates 340 on the end surface facing the crushing main shaft 200.

When the pushing plate 300 pushes the waste to the crushing main shaft 200, the tooth plate 340 can effectively prevent the material from slipping, which is beneficial to the crushing main shaft 200 to process the waste and improve the working efficiency, and the tooth plate 340 is also beneficial to preventing the waste from being adhered to the pushing plate 300.
