In the production process of the hidden tea cup, the raw materials (such as cup body base material corn fiber, sugarcane residue and other degradable materials) need to be finely crushed to ensure the quality of the finished product.
[0003] In the crushing process of the existing hidden tea cup, the raw materials of the hidden tea cup need to be crushed by the crushing device. However, the existing crushing device for crushing the raw materials of the hidden tea cup still has the following shortcomings in actual use, for example: in the process of crushing the raw materials of the hidden tea cup for a long time, the mesh holes of the screen are easily blocked by debris. In order to not affect the screening effect of the screen, the staff need to use tools to clean the blockage, and the machine also needs to be stopped for cleaning, which greatly reduces the production efficiency of the raw materials of the hidden tea cup.

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0031] Example 1: Please refer to Figures 1 to 6 :
[0032] This utility model proposes a raw material crushing and screening device for hidden tea cups, comprising: a crushing box 1, a main shaft 101 rotatably connected to the upper side inside the crushing box 1, and crushing blades 102 installed on the outside of the main shaft 101; a U-shaped screen 2 is arranged inside the crushing box 1 outside the crushing blades 102; three striking mechanisms 3 are arranged inside the crushing box 1 below the U-shaped screen 2; and a linkage 4 is arranged on the lower side inside the crushing box 1; the striking mechanism 3 includes a moving frame 301, a striking hammer 302, a sliding block 303, a vertical guide rod 304, and a triangular prism 305. A sliding block 303 is fixedly connected to both the front and rear end faces of the moving frame 301, and a vertical guide rod 304 is slidably connected to the outside of each sliding block 303. A triangular prism 305 is fixedly connected to the lower end of 304, and the triangular prism 305 is fixedly installed inside the crushing box 1. A striking hammer 302 is fixedly connected to the top of the moving frame 301. A spring is sleeved on the outside of each vertical guide rod 304 between the sliding block 303 and the triangular prism 305. Through the setting of the linkage 4 and the striking mechanism 3, the striking hammer 302 frequently collides with the bottom of the vibrating rod 202, thereby causing the vibrating rod 202, the two support rods 201 and the U-shaped screen 2 to vibrate as a whole. Then, under the action of vibration, the debris blocked in the mesh of the U-shaped screen 2 is removed. Thus, when clearing the blockage, there is no need for the staff to use tools to clear the blockage, and there is no need to stop the machine to clear the blockage. Therefore, the production efficiency of the raw materials for the hidden tea cup is greatly improved.
[0033] A crushing motor 103 is installed on the left end face of the crushing box 1, and a worm gear 104 is connected to the shaft of the crushing motor 103 through a coupling. A worm wheel 105 and a transmission pulley 107 are fixedly installed on the left and right ends of the main shaft 101, respectively, and the worm wheel 105 meshes with the worm gear 104. A collection hopper 106 is installed at the bottom of the crushing box 1 for collecting the crushed raw materials.
[0034] A support rod 201 is fixedly connected to the left and right sides of the bottom of the U-shaped screen 2. A guide rod 203 is fixedly connected to the front and back sides of the upper end of each support rod 201. A guide slider 204 is slidably connected to the outside of each guide rod 203. The guide slider 204 is fixedly connected inside the crushing box 1. A circular limiting block 205 is fixedly connected to the upper end of each guide rod 203. A spring is sleeved on the outside of each guide rod 203 between the support rod 201 and the guide slider 204. A vibrating rod 202 is fixedly connected to the middle of the opposite face of the two support rods 201. The vertical cross-section of the vibrating rod 202 is pentagonal, which allows the raw material falling to the top of the vibrating rod 202 to slide down automatically under the action of the slope, avoiding the accumulation of raw material at the top of the vibrating rod 202.
[0035] Example 2, based on Example 1, such as Figure 2 , Figure 4 and Figure 5 As shown, the linkage 4 includes a linkage shaft 401, a cam 402, and a driven pulley 403. The linkage shaft 401 is rotatably connected inside the crushing chamber 1, and the driven pulley 403 is fixedly installed at the right end of the linkage shaft 401. The driven pulley 403 is connected to the transmission pulley 107 via a belt. Three cams 402 are fixedly installed outside the linkage shaft 401, and the three cams 402 are located inside the three moving frames 301 respectively. When the protrusion of the cam 402 faces downward, the protrusion of the cam 402 pushes the moving frame 301 downward, and at this time the external spring of the vertical guide rod 304 is in a compressed state. When the protrusion of the cam 402 faces upward, the sliding block 303 moves the moving frame 301 and the striking hammer 302 upward, and at this time the upper end of the striking hammer 302 collides with the bottom of the vibrating rod 202. Through the cooperation of the linkage 4 and the transmission pulley 107, when the striking mechanism 3 is operating, there is no need to configure a motor, which not only reduces the cost of motor purchase, installation and maintenance, but also effectively reduces energy consumption.
[0036] The working principle of this embodiment is as follows: When crushing the raw materials for the hidden tea cup, the crushing motor 103 is started first, which drives the worm gear 104, worm wheel 105 and main shaft 101 to rotate. Then, the main shaft 101 drives the crushing blades 102 to rotate. The raw materials for the hidden tea cup to be crushed are then put into the upper part of the crushing chamber 1. At this time, the crushing raw materials for the hidden tea cup are crushed by the rotating crushing blades 102. The crushed raw materials for the hidden tea cup are screened through the U-shaped screen 2. The raw materials for the hidden tea cup that meet the volume requirements fall downward into the collection hopper 106 and are finally discharged through the lower outlet of the collection hopper 106.
[0037] During the rotation of the main shaft 101, the transmission pulley 107, driven pulley 403, linkage shaft 401, and three cams 402 rotate. When the protrusion of cam 402 faces downward, the protrusion of cam 402 pushes the moving frame 301 downward, and at this time, the external spring of vertical guide rod 304 is in a compressed state. Then, when the protrusion of cam 402 faces upward, the sliding block 303 moves the moving frame 301 and the hammer 302 upward rapidly under the elastic force of the external spring of vertical guide rod 304. At this time, the upper end of hammer 302 collides with the bottom of vibrating rod 202, thereby causing the vibrating rod 202, the two support rods 201, and the U-shaped screen 2 to vibrate as a whole. Then, under the action of vibration, the debris blocked in the mesh of U-shaped screen 2 is removed. Thus, during the unblocking process, no operator is required to use tools to unblock the blockage, and the machine does not need to be stopped for unblocking.
