Detailed Implementation

[0022] To better understand this utility model, the following embodiments further illustrate its content, but the scope of protection of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.

[0023] like Figure 1 , 2 As shown, a jaw crusher includes a base 101, a support 103 fixedly connected to the base 101, a crusher body 102 fixedly connected to the support 103, a bracket 104 fixedly connected to the base 101 spanning the upper side of the crusher body 102, a vertically vibrating feed box 105 with a converging frustum shape at the lower end mounted on the bracket 104, the converging frustum shape at the lower end of the feed box 105 allows the material to flow smoothly downwards to the discharge cylinder 107 at the bottom, a feed inlet 106 is opened at the top of the feed box 105, and the discharge cylinder 107 is fixedly connected to the bottom of the feed box 105, with a control valve 108 installed on the discharge cylinder 107.

[0024] like Figure 1 As shown, multiple springs 201 are vertically fixed on the bracket 104, and a mounting plate 202 connected to the upper end of the multiple springs 201 is fixed to the side end of the feed box 105. A vibration motor 203 is fixed on the mounting plate 202. A guide tube 204 is also vertically fixed on the bracket 104, and a guide rod 205 that is inserted into the guide tube 204 is also fixed on the mounting plate 202.

[0025] Workers can first add sufficient material to be crushed into the feed box 105 through the feed inlet 106, then start the crusher body 102 and activate the control valve 108 to control the discharge speed, so that the material leaves the feed box 105 through the feed pipe and falls into the crusher body 102 at an appropriate speed for crushing. Automatic feeding of the crusher body 102 is achieved according to the appropriate feeding speed and feed amount, so that workers do not need to add material to be crushed to the feed end of the crusher body 102 by special effort; they only need to replenish the material to be crushed into the feed box 105 at regular intervals.

[0026] At the same time, the vibration motor 203 can be started. With the cooperation of multiple springs 201 and the insertion cooperation of guide rod 205 and guide cylinder 204, the feed box 105 can vibrate vertically stably, avoiding blockage of the discharge cylinder 107, thereby improving the smoothness of automatic feeding.

[0027] According to another embodiment of the present invention, such as Figure 2 As shown, a transparent observation window 111 is also provided on the feed hopper 105.

[0028] According to another embodiment of the present invention, such as Figure 3 As shown, a guide chute 112 is also installed at an incline on the lower side of the discharge end of the crusher body 102, and a connecting rod 113 connected to the guide chute 112 is also provided on the feed box 105. During the vibration operation, the feed box 105 can also drive the guide chute 112 to vibrate vertically through the connecting rod 113, so that the material falling into the guide chute 112 after crushing can be discharged smoothly, facilitating subsequent receiving and other operations.

[0029] According to another embodiment of the present invention, such as Figure 4 As shown, a connecting slot 114 located below the guide trough 112 is also fixedly connected to the base 101, and a connecting plate 115 that plugs into the connecting slot 114 is fixedly connected to the bottom of the guide trough 112. Through the insertion and cooperation of the guide slot and the guide plate, the vibration process of the guide trough 112 can be assisted in guiding, avoiding the vertical guiding effect and guiding stability during vibration operation due to the distance from the guide trough 112, and preventing the connecting rod 113 from being deformed and damaged by the offset force.

[0030] In summary, the jaw crusher's workflow achieves automation and high efficiency from material feeding and crushing to discharge, while also enhancing the equipment's safety and stability through multiple improvement measures.

[0031] According to another embodiment of the present invention, such as Figure 1 As shown, a protective cover 116 is also fixedly connected to the upper end of the crusher body 102, covering the outside of the discharge cylinder 107. The protective cover 116 can prevent material from splashing during the process of leaving the discharge cylinder 107 and falling into the crusher body 102; and can effectively prevent material from splashing during the crushing process, improving the safety of equipment use and protecting operators from injury.

[0032] According to another embodiment of the present invention, such as Figure 4 As shown, an extension plate 117 is also fixedly connected to the side end of the base 101, and anchor bolts 118 for connecting to the ground are screwed onto the extension plate 117. Workers can pass the anchor bolts 118 through the extension plate 117 and connect them to the ground, thereby enhancing the stability of the entire equipment during installation, adapting to different ground environments, and ensuring smooth operation of the equipment.

[0033] The above are preferred embodiments of this utility model.
