An elastic telescopic rod 405 is fixedly connected to the rear of the supporting piece 404. The elastic telescopic rod 405 can be elastically reset after being released after compression, and a pushing seat 406 is fixedly connected to the rear end of the elastic telescopic rod 405. The pushing seat 406 is L-shaped, and the front of the pushing seat 406 is fixedly connected to the A rack 407, a support piece 404, an elastic telescopic rod 405 and a first rack 407 are three in number. A top moving piece 6 is provided on the front of the first rack 407. The top moving piece 6 is provided in three groups and is respectively provided on the three first racks 407. The top moving piece 6 includes a swing bar 601, which is hinged to the bottom of the first rack 407. A sliding groove 602 is provided on the outer surface of the swing bar 601. The inner surface of the sliding groove 602 is slidably connected to the limit seat 603. The limit seat 603 specifically includes a U-shaped seat and a cylindrical block.

The inner surface of the tank body 1 is provided with a toggle Part 7, the toggle part 7 includes a rotating rod 701, there are three rotating rods 701, the rotating rod 701 is rotatably connected to the bottom of the inner surface of the tank body 1, the rotating rod 701 is penetrated and slidably connected to the bottom of the liner 4, the rotating rod 701 is penetrated and rotatably connected to the top of the tank body 1, and a dial plate 702 is fixedly connected to the outer surface of the rotating rod 701. Two dial plates 702 are provided on each rotating rod 701. The dial plates 702 are arranged at the interval between each two layers of crushing blades 3. The outer surface of the rotating rod 701 is fixedly connected to the first gear 703, the first gear 703 is engaged with the first rack 407, and a feed bin 408 is fixedly connected to the top of the tank body 1. The feed bin 408 is the thickest at the top and the thinnest at the bottom. The inner surface of the feed bin 408 is equipped with a feeding assembly 8, and the bottom of the tank body 1 is equipped with a discharging assembly 9.

[0025] When the above-mentioned equipment is used, the agricultural products that need to be sampled are first put into the feed bin 408. The agricultural products will fall into the tank body 1 through the feed bin 408 and fall into the inner liner 4. At this time, the motor 502 is started, and the motor 502 will drive the rotating shaft 2 to rotate. The rotation of the rotating shaft 2 will drive the crushing blade 3 to rotate. The rotation of the crushing blade 3 will crush the agricultural products in the inner liner 4. At this time, as the rotating shaft 2 rotates, the pushing block 403 will also be driven to rotate. The pushing block 403 will continue to push toward the pushing seat 406, causing the elastic telescopic rod 405 to contract. When the pushing block 403 leaves the pushing seat 406, the elastic telescopic rod 405 will drive the pushing seat 406 to reset, so that the pushing seat 406 will continue to approach and move away from the rotating shaft as the pushing block 403 rotates. The rotating shaft 2, at this time, the pushing seat 406 will drive the first rack 407 to move back and forth continuously. The continuous back and forth movement of the first rack 407 will drive the first gear 703 to rotate forward and reverse continuously, thereby driving the rotating rod 701 to rotate forward and reverse continuously, so that the paddle plate 702 continuously pokes the agricultural products in the inner tank 4, thereby enhancing the crushing effect of the agricultural products. At this time, as the first rack 407 continuously moves back and forth, it will also drive the upper end of the swing bar 601 to move continuously. Under the action of the limiting seat 603 located in the middle of the swing bar 601, its lower end will continuously swing, thereby driving the top block 604 to continuously push against the ring body 402, causing it to shake. The ring body 402 will drive the discharge pipe 401 and then drive the inner tank 4 to continuously shake the agricultural products, thereby further enhancing the crushing effect.

[0026] Example 2, see Figure 2-Figure 6The feeding component 8 includes a first rotating column 801, which passes through the front and back sides of the feeding bin 408 and is rotatably connected. The first rotating column 801 enters the feeding bin 408 from the front and exits from the back. A bearing is provided between the first rotating column 801 and the feeding bin 408. A limiting plate 802 is fixedly connected to the outer surface of the first rotating column 801. There are four limiting plates 802, forming a cross on the first rotating column 801. A first supporting block 803 is fixedly connected to the left side of the feeding bin 408. The front of the first supporting block 803 is rotatably connected to the second rotating column 804. A first chain condition 805 is transmission-connected between the second rotating column 804 and the first rotating column 801. The first chain condition 805 includes a sprocket and a chain. The second rotating column 804 and the first rotating column 801 are both provided with a sprocket for chain transmission. A second gear 806 is provided on the outer surface of the second rotating column 804. A one-way bearing is fixedly connected between the two gears, which can limit the one-way rotation of the second gear 806 on the second rotating column 804. The second gear 806 can specifically rotate counterclockwise on the second rotating column 804. A second rack 807 is engaged below the second gear 806, and the second rack 807 is fixedly connected to the top of the pushing seat 406. The feeding assembly 8 also includes a third rotating column 808, which penetrates and is rotatably connected to the back of the feeding bin 408. A bearing is provided between the third rotating column 808 and the feeding bin 408. A second chain condition 809 is transmission-connected between the third rotating column 808 and the first rotating column 801. The second chain condition 809 includes a sprocket and a chain. Both the third rotating column 808 and the first rotating column 801 are provided with a sprocket for chain transmission. A toggle rod 810 is fixedly connected to the outer surface of the third rotating column 808. There are four toggle rods 810, which are respectively arranged on the left and right sides of the third rotating column 808 in pairs.

[0027] When the above-mentioned equipment is used, the agricultural products put into the feed bin 408 will fall above the limiting plate 802. At this time, as the push seat 406 moves back and forth, it will drive the second rack 807 to move left and right continuously. The one-way bearing will limit the second gear 806 to only rotate counterclockwise on the second rotating column 804. When the second rack 807 moves to the left and the second gear 806 rotates clockwise, the second gear 806 will drive the second rotating column 804 to rotate clockwise. The clockwise rotation of the second rotating column 804 will drive the first chain condition 805 to make the first rotating column 801 rotate clockwise. Rotation: The clockwise rotation of the first rotating column 801 will drive the limiting plate 802 to rotate clockwise around the first rotating column 801. Since the pushing seat 406 will be continuously pushed by the pushing block 403, the limiting plate 802 will rotate intermittently, thereby intermittently unloading agricultural products in batches during the rotation process. At this time, as the first rotating column 801 rotates, the second chain condition 809 will also be driven to rotate the third rotating column 808. The rotation of the third rotating column 808 will drive the toggle rod 810 to continuously toggle the agricultural products in the feed bin 408 to prevent them from accumulating and clogging.

The discharging assembly 9 also includes a first hydraulic warehouse 911, which is fixedly connected to the top of the tank body 1. The inner surface of the first hydraulic warehouse 911 is slidably connected to the first hydraulic rod 912.

[0029] When the above-mentioned device is used, the push seat 406 will drive the first rack 407 to move back and forth continuously, and at the same time, the first hydraulic rod 912 will be driven to move left and right continuously in the first hydraulic chamber 911. The first hydraulic rod 912 will continuously extract the liquid in the second hydraulic chamber 913 through the hose 914, so that the second hydraulic rod 915 will continuously expand and contract in the second hydraulic chamber 913. At this time, the second hydraulic rod 915 will continuously rise and fall. The continuous rise and fall of the second hydraulic rod 915 will drive the fourth rack 916 to slide up and down on the support plate 917. The fourth rack 916 will drive the fourth gear 910 to continuously rotate forward and reverse. The fourth gear 910 will drive the screw 908 to rotate intermittently in one direction under the action of the one-way bearing. The rotation of 8 will drive the third rack 909 to slide to the right, and the sliding of the third rack 909 to the right will eventually drive the third gear 906 to make the rotating seat 903 rotate a small angle until the third rack 909 passes the third gear 906, and the rotation of the rotating seat 903 will drive the limiting telescopic rod 904 to rotate, and the rotation of the limiting telescopic rod 904 will drive the second leak plate 905 to rotate a small angle below the first leak plate 409. At this time, the hollow part on the second leak plate 905 will coincide with the hollow part on the first leak plate 409, and the crushed agricultural products in the liner 4 will leak through the hollow parts on the second leak plate 905 and the first leak plate 409 and fall into the collecting trough 901, thereby automatically unloading after being crushed for a certain period of time.
