After loosening the bolt 6, the pull-out plate 5 and the collecting box 4 can be pulled out to the right to facilitate material removal.

[0032] In this embodiment, Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, a transparent plate 802 is inlaid on the top of the cover shell 801, and a support frame 806 is fixed to the top of the cover shell 801. One side of the rear inner wall of the support frame 806 is rotatably connected to the first circular gear 807, and the front side of the first circular gear 807 is fixed with a belt transmission assembly 808. The belt transmission assembly 808 is rotatably connected to the front inner wall of the support frame 806, and the rear side of the belt transmission assembly 808 is fixed with a first bevel gear 809. A cam 810 is fixed to the rear side of the first bevel gear 809, and the cam 810 is rotatably connected to the other side of the rear inner wall of the support frame 806. When the handle 901 is held by hand and the tamping block 905 is moved up and down to tamp the material, the first circular gear 807 rotates back and forth, thereby driving the belt transmission assembly 808, the first bevel gear 809 and the cam 810 to rotate back and forth as a whole.

When the cam 810 rotates, the first piston 815 can move up and down under the squeezing of the cam 810 and the supporting action of the compression spring 817, which is convenient for repeatedly pumping and pressing the hydraulic oil in the cylinder 816. The roller 814 rolls on the cam 810, which is convenient for reducing the friction between the first piston 815 and the cam 810.

[0035] In this embodiment, Figure 3 、 Figure 6 and Figure 7 As shown, a tooth groove 902 is provided on one side of the handle 901, and the tooth grooves 902 are evenly spaced on the handle 901. The first circular gear 807 is meshed and connected in the tooth groove 902. A limit ring 903 is fixed to the outside of the handle 901. Since the first circular gear 807 is meshed and connected with the tooth groove 902, the first circular gear 807 can be driven to rotate forward and reverse during the process of moving the handle 901 up and down, and the limit ring 903 plays a limiting role in the process of moving the handle 901 upward.

[0036] In this embodiment, Figure 3 、 Figure 6 、 Figure 7 and Figure 8 As shown, an oil groove 906 is provided in the tamping block 905, and the oil groove 906 is connected to the oil cylinder 816 through a connecting pipe 904. A second piston 907 is slidably connected in the oil groove 906, and a movable plate 908 is fixed to the bottom of the second piston 907.

The grip 901 moves up and down to drive the first circular gear 807, the belt transmission assembly 808, the first bevel gear 809 and the cam 810 to rotate forward and reverse as a whole. When the grip 901 moves up, the cam 810 squeezes the first piston 815 to move up. At this time, the second piston 907, the movable plate 908 and the cutting knife 910 move up as a whole, and the cutting knife 910 retracts into the tamping block 905. When the grip 901 moves down, the cam 810 releases the squeeze on the first piston 815, and the first piston 815 is compressed by the spring 81 7, it automatically springs down, the second piston 907, the movable plate 908 and the cutting knife 910 move downward as a whole, and the cutting knife 910 extends from the bottom of the tamping block 905, which is convenient for automatically cutting the agricultural products. The use of the tamping block 905 and the cutting knife 910 in combination can make the tamping effect more efficient and thorough. At the same time, the second bevel gear 811, the rotating shaft 812 and the second circular gear 813 rotate back and forth, thereby driving the ring gear 804 and the two scraping bars 805 to rotate back and forth as a whole. The two scraping bars 805 can automatically scrape off the agricultural products on the inner wall of the second groove 7 and the inner wall of the cover 801, and the mashed agricultural products fall into the collecting box 4. After loosening the bolt 6, the pulling plate 5 and the collecting box 4 can be pulled out.
