[0025] The content of the present invention will be described below with reference to specific embodiments.

[0026] like Figures 1~3 shown, figure 1 It is a schematic structural diagram of the crop seed treatment device proposed by the present invention; figure 2 Yes figure 1 Schematic diagram of the structure of the part where the middle sieving cylinder is located; image 3 Yes figure 1 Schematic diagram of the structure of the part where the middle screening drum and the mixing drum are located.

[0027] refer to Figures 1~3 , The crop seed processing device includes: a frame 1 and a screening drum 2 connected to the frame 1, a return drum and a mixing drum.

[0028] The screening drum 2 is vertically installed on the frame 1, and the horizontal cross-sectional area of the screening drum 2 gradually decreases from top to bottom; There is a separation port 22, and the bottom is provided with a return port 23 and a discharge port 24; a filter screen 3 is provided between the separation port 22 and the feed port 21, and the aperture of the filter screen 3 is larger than the particle size of the seeds; The separation port 22 is communicated with the fan 4 through a separation pipe, and the fan 4 is also communicated with a cloth bag 5; baffle plate 6, the baffle plate 6 can be driven by the first power device 7 to move horizontally;

[0029] The return cylinder 8 is installed on the frame 1 obliquely. The bottom of the return cylinder 8 is connected to the return port 23 of the screening cylinder 2 through the first return pipe, and the top is connected to the screen through the second return pipe. The feeding port 21 of the screening drum 2 is communicated; the feeding channel is arranged inside the feeding drum 8 along its axis direction, and a feeding screw 9 is rotatably connected in the feeding channel, and the feeding screw 9 can be driven by the second power The device 10 is driven to rotate;

[0030] The mixing drum 11 is vertically installed on the frame 1, the mixing drum 11 is located directly below the screening drum 2, and a mounting rod 12 is connected in the mixing drum 11 along its axial direction, and the mounting rod The outer periphery of 12 is sleeved with blades 13, and the installation rod 12 is driven and rotated by the third power device 14; the mixing cylinder 11 is also connected with a liquid storage cylinder 15 through a pipeline, and the liquid storage cylinder 15 is filled with auxiliary liquid.

[0031] In this embodiment, the seeds are poured into the screening drum 2 , and the outlet of the screening drum 2 is closed by the baffle plate 6 . Impurities such as pebbles are isolated on the filter screen 3, and the seeds continue to fall by gravity. The fan 4 and the second power device 10 are started, and when the seeds pass through the separation port, the partially dried seeds mixed in the seeds and other impurities enter the cloth bag 5 through the separation pipe under the action of wind. The remaining seeds continue to fall, and enter the return barrel 8 from the first return pipe when passing through the return port. The second power device 10 drives the feeding screw 9 to rotate, and the feeding screw 9 drives the seeds to move upward during the rotation process. When the seeds move to the top of the return barrel 8, the second return pipe re-enters the screening barrel 2, so as to complete a screening process.

[0032] Since the seeds can be continuously screened by repeating the above operations, the screening efficiency and screening effect of the seeds are greatly improved.

[0033] The shape arrangement of the screening drum 2 enables the seeds at the bottom of the screening drum 2 to enter the return drum 7 more conveniently, thereby enhancing the screening efficiency. In addition, this design can also ensure that the spread surface when the seeds fall will not be too small, and the shriveled seeds and other impurities can be more easily separated and entered into the cloth bag 6, thereby improving the screening effect.

[0034] The filter screen 3 can isolate impurities such as gravel and improve the screening effect. In order to improve the screening efficiency, so that the seeds can move downward through the mesh holes more smoothly, in the specific design, the filter mesh 3 can be designed into an arc shape with an upward opening. The filter screen 3 can also be designed to be detachable, so as to facilitate the cleaning of the crushed stones after screening.

[0035] After the impurities in the seeds are completely separated, the fan 4 and the second power device 10 can be turned off, and the first power device 7 and the third power device 14 can be turned on. The discharge port 24 of the screening drum 2 can be exposed through the first power device 7, and the seeds in the screening drum 2 enter the mixing drum 11 through the pipeline under the action of gravity. Since the liquid storage cylinder 15 can spray auxiliary liquid into the mixing cylinder 11, when the third power device 14 drives the blades 13 to rotate, the seeds are fully contacted with the auxiliary liquid by the blades 13, and the mixing process is completed.

[0036] Since the seeds can attach the auxiliary liquid to the surface of the seeds in time after the sieving treatment, the time of subsequent treatment can be shortened, the treatment cycle of the seeds can be shortened, the sowing effect of the seeds can be improved, and the germination rate of the seeds can be improved.

[0037] In order to conveniently and timely deliver the auxiliary liquid into the mixing cylinder 11 and make the auxiliary liquid on the surface of the seeds more uniform, the yield of the seeds is kept within a stable range. In the specific design, the inner wall of the mixing cylinder 11 is clamped with a liquid feeding pipe 16, the mixing cylinder 11 is communicated with the liquid storage cylinder 15 through the liquid feeding pipe 16, and a plurality of liquid feeding pipes 16 are alternately distributed on the liquid feeding pipe 16. Liquid injection port.

[0038] After the seeds are mixed, they need to be unloaded in time. Therefore, a discharge pipe 17 is connected to the bottom of the mixing cylinder 11 , and an electric control valve is provided on the discharge pipe 17 . The falling speed of the seeds can be controlled by the opening of the solenoid valve.

[0039] In this solution, the discharge pipe 17 is at a certain height from the ground, and it is easy to cause the seeds to deviate from the material frame during unloading, which is inconvenient for cleaning and collection. Therefore, a feed pipe 18 is connected to the discharge pipe 17 .

[0040]In order to realize the automation of material discharge, the processed seeds can be sent out in time. The solution also includes a material discharge conveyor belt 20 , a material frame 19 is connected to the material discharge conveyor belt 20 , and there is a gap between the material frame 19 and the material guide pipe 18 . After the screening and mixing of the seeds are completed, the solenoid valve is opened, and the seeds are dropped into the material frame 19 from the mixing drum 11 . When the seeds are filled with the material frame 19 , the solenoid valve is closed, and the material frame 19 is conveyed out through the discharge conveyor belt 20 .

[0041] During the screening process, the seeds in the screening drum 2 need to enter the feeding drum 8 through the first feeding pipe. If the movement speed of the seed is too fast, it will collide with the feeding screw 9, resulting in the rupture of the seed epidermis, affecting the normal production of the seed, thereby reducing the germination rate of the seed. Therefore, the first return pipe is provided with a flow control valve, and the movement speed of the seeds in the first return pipe can be adjusted by controlling the opening of the flow control valve.

[0042] When the seeds are mixed with too much water, the germination rate of the seeds will also be reduced. In the specific design, a feeding chute 25 is connected to the discharge port of the screening drum 2 , and the feeding chute 25 is arranged obliquely, and its bottom end is located above the mixing drum 11 . After the discharge port 24 of the screening drum 2 is exposed, the seeds will enter the mixing drum 11 through the feeding chute 25 . Since the feeding chute 25 has a certain slope, the seeds will be fully exposed to the air when moving on the feeding chute 25, and workers can use a heater to dry the seeds.

[0043] In order to enable the seeds to move evenly along the feeding chute 25, thereby ensuring the drying effect of the seeds, the feeding chute 25 is provided with limit plates 26 on one side close to the screening drum 2, and both ends of the limit plates 26 are provided. The screening drum 2 and the feeding chute 25 are respectively connected.

[0044] Drying the seeds with a heater will cause certain damage to the seeds and reduce the germination rate of the seeds. Therefore, this solution also includes an air supply mechanism 27 and a plurality of air ducts 28 communicating with the air supply mechanism 27 . When the seeds move along the feeding chute 25, the air supply mechanism 27 can continuously supply air to the seeds through the air duct 28, so as to realize the drying process of the seeds.

[0045] The above descriptions are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention shall be included in the protection of the present invention. within the range.
