An ear plate 8 and a wire plate 11 are fixedly connected to one side of the material box 4. A sliding assembly is arranged on the ear plate 8. The sliding assembly includes a T-shaped rod 7 slidably arranged on the ear plate 8. The lower end of the T-shaped rod 7 is fixedly connected to a cross plate 9. The cross plate 9 is connected to the slide rod 18 through a pull rope 12. A guide hole for the pull rope 12 to pass through is provided on the wire plate 11. The wire plate 11 has a certain limiting effect on the moving trajectory of the pull rope 12. A cam 10 is rotatably arranged on one side of the material box 4, and a motor for driving the cam 10 is fixedly connected to one side of the material box 4.
[0023] Two fixed blocks 13 with L-shaped cross-sections are fixedly connected to the slide bar 18. The surface of each fixed block 13 fits with the surface of the material box 4. During the rotation of the cam 10, it will continuously contact and disengage from the cross plate 9. The slide bar 18 will slide relative to the material box 4 many times, and the surface of the fixed block 13 will hit, fit, and disengage from the surface of the material box 4 many times. When the fixed block 13 hits and fits the surface of the material box 4, the material box 4 vibrates, which can effectively prevent the corn seeds from sticking to the inner wall of the storage cavity 16.
[0024] A mounting rod 14 is provided on one side of the support column 5, and a paving rake 17 is fixedly connected to the mounting rod 14. The mounting rod 14 is connected to the support column 5 by bolts. A threaded groove is provided on one side of the support column 5, and a slide groove is provided on the upper surface of the machine body 1. The lower end of the paving rake 17 extends into the seeds on the filter frame 20. When the paving rake 17 moves with the support column 5, the corn seeds on the filter frame 20 can be paved and dispersed, which can effectively prevent the seeds from piling up. One end of the bolt is passed through the mounting rod 14 and threadedly connected to the threaded groove. The mounting rod 14 and the support column 5 can be firmly connected together, and the lower end of the support column 5 is slidably connected to the slide groove.
[0025] A feed pipe 6 is fixedly connected to the material box 4, and a pipe cover is threadedly connected to the feed pipe 6. A liquid outlet pipe 2 is fixedly connected to one side of the body 1, and a manual valve is provided on the liquid outlet pipe 2. The pipe cover and the feed pipe 6 are threadedly connected together. The pipe cover has a good shielding effect on the pipe mouth of the feed pipe 6 to prevent dust and impurities from entering the storage chamber 16 through the feed pipe 6. When the manual valve is opened, the water flow inside the water storage chamber can be discharged through the liquid outlet pipe 2.
[0026] In the utility model, when in use, firstly, a sufficient amount of corn seeds are put into the storage chamber 16 through the feeding pipe 6. At this time, the side surfaces of the sealing plate 15 are in contact with the inner wall of the storage chamber 16, which can effectively prevent the corn seeds from escaping from the storage chamber 16. Then, one motor drives the reciprocating screw rod 3 to rotate, and the other motor drives the cam 10 to rotate. During the rotation of the reciprocating screw rod 3, the support column 5 will move along the reciprocating screw rod 3, thereby driving the material box 4 to move together. During the rotation of the cam 10, it will be squeezed and separated from the lower surface of the cross plate 9 for many times. During the rotation of the cam 10 against the lower surface of the cross plate 9, under the transmission action of the cross plate 9, the T-shaped rod 7 and the ear plate 8 slide relative to each other at the same time. During the upward movement of the cross plate 9, one end of the inelastic pull rope 12 is fixedly connected to the sliding rod 18, and the other end is fixedly connected to the cross plate 9. Under the transmission action of the pull rope 12, The slide bar 18 and the material box 4 slide relative to each other. Since one end of the spring 19 is fixedly connected to the surface of the material box 4 and the other end is fixedly connected to the slide bar 18, the spring 19 is deformed. After the sealing plate 15 moves with the slide bar 18, there will be a gap between the sealing plate 15 and the inner wall of the storage chamber 16, and the corn seeds can pass through the gap and fall onto the filter frame 20. After the cross plate 9 is disengaged from the cam 10, the sealing plate 15 moves to the initial position and the above process is repeated. During the movement of the material box 4, the corn seeds can be intermittently put into the filter frame 20. During the movement of the leveling rake 17 together with the support column 5, the corn seeds on the filter frame 20 can be leveled and dispersed, which can effectively prevent the seeds from piling up. The corn seeds are laid evenly, so that the water absorption rate of the seeds is the same, and the saturation of water absorption of the seeds is the same, which is beneficial to improving the accuracy of seed vitality detection.
[0027] In the present invention, unless otherwise clearly specified or limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense.
[0028] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
