Description

Technical Field

[0001] The utility model relates to the technical field of seed selection, and particularly relates to a seed selection device with low damage to seeds. Background Art

[0002] A large number of high-quality seeds are required for agricultural sowing. However, there are many underfilled seeds and some seeds with smaller sizes in the seeds, and there are also some impurities at the same time. The underfilled seeds cause a reduction in yield, and a screening device is needed to screen the seeds.

[0003] When screening seeds, generally multiple screening meshes with different pore sizes are used to screen the seeds. In order to improve the efficiency during the screening process, a vibration motor is generally used to drive the screening mesh to vibrate. During the vibration process, the seeds and impurities such as stones will collide continuously, thus causing damage to the complete fine seeds.

[0004] For this reason, a seed selection device with low damage to seeds is proposed. Content of the Utility Model

[0024] Such as Figures 1-4As shown, a low-damage seed selection device comprises a selection box 1, on which a separation member 9 for classifying small impurities is arranged, the separation member 9 comprises a second motor 901 arranged on one side of the selection box 1 and two belt conveyor rollers 902 rotatably arranged inside the selection box 1, a belt 903 is rotatably arranged between the two belt conveyor rollers 902, a surface of the belt 903 is provided with a plurality of evenly arranged baffles 904, the belt 903 is of an inclined design, a fixed plate 4 is arranged inside the selection box 1, a first impurity collection box 401 is placed on the fixed plate 4, a screening net 5 is arranged inside the selection box 1, a vibration motor 6 is arranged at the bottom end of the screening net 5, the screening net 5 is of an inclined design, and a fine product collection box 7 and a second impurity collection box 8 are arranged at the bottom end of the selection box 1; specifically, after the seeds are put into the selection box 1, since the seeds are spherical and have inertia, and the belt 903 is of an inclined design, the seeds will roll down along the inclined direction of the belt 903, and some smaller particles of stones and broken seeds will get stuck in the baffles during the rolling process due to their irregular shapes. 904, the second motor 901 can drive the belt conveyor roller 902 to rotate, and the rotation of the belt conveyor roller 902 can drive the belt 903 to rotate in the direction opposite to the rolling direction of the seeds, so that the stuck impurities will fall into the first impurity collection box 401 under the conveying action of the belt 903, so that small pieces of impurities can be collected, and the baffle 904 is made of silicone material, so that the seeds will not be damaged by collision during the rolling process, and the height of the baffle 904 is less than the diameter of the seeds, so that The seeds will be stuck. For some seeds with lighter weight and lower inertia, the seeds will be blocked between the baffle bars 904. In order to improve the efficiency of seed rolling, corresponding vibration equipment can also be set between the belts 903. No more details are given here. The seeds that have been initially screened can fall onto the screening net 5. Then, under the action of the vibration motor 6, the seeds and large impurities can be quickly screened and separated. The selected seeds can fall into the interior of the fine collection box 7, and the large impurities can fall into the interior of the second impurity collection box 8.

[0025] like Figure 1 As shown, a sealing door 101 is hinged on one side of the selection box 1; specifically, the collected impurities and selected seeds can be conveniently taken out through the sealing door 101.

[0026] like Figures 2-4As shown in the figure, a feeding and conveying member 2 for driving seeds for feeding is arranged on the selection box 1. The feeding and conveying member 2 includes a conveying box 201 arranged at the top of the selection box 1, a feeding hopper 202 arranged at the top of the conveying box 201, a first motor 203 arranged on one side of the conveying box 201, a spiral conveying roller 204 connected to the main shaft end of the first motor 203, a discharge hopper 205 arranged on the conveying box 201, and a plurality of guide plates 206 arranged inside the discharge hopper 205; specifically, when the first motor 203 works, it can drive the spiral conveying roller 204 to rotate. When the spiral conveying roller 204 rotates, it can push the seeds forward for conveying. Under the action of the guide plates 206, the seeds can evenly fall onto the surface of the belt 903.

[0027] As Figure 2 As shown in the figure, a dust suction member 3 for adsorbing dust is arranged on the selection box 1. The dust suction member 3 includes a dust collection box 301 arranged on one side of the selection box 1 and a dust suction plate 304 arranged on one side inside the selection box 1. Vent holes 305 are formed in the dust suction plate 304. The dust collection box 301 is communicated with the dust suction plate 304. An air pump 303 is arranged on one side of the dust collection box 301. The input end of the air pump 303 extends into the interior of the dust collection box 301. A filter screen 302 is arranged inside the dust collection box 301; specifically, when the air pump 303 works, it can suck the dust inside the selection box 1 into the interior of the dust collection box 301. Under the filtering action of the filter screen 302, the clean air can be discharged outward. The dust raised during the process of the seeds falling downward and rolling on the belt 903 can be sucked away.

[0028] As Figure 2 As shown in the figure, the first impurity collection box 401 is arranged directly above the second impurity collection box 8.

[0029] As Figure 2 As shown in the figure, the fine product collection box 7 is arranged directly below the screening mesh 5.

[0030] In summary: After the seeds are put into the interior of the selection box 1, since the seeds are spherical and have inertia, and the belt 903 is inclined, the seeds will roll downward along the inclined direction of the belt 903. Some small-particle stones and broken seeds will be stuck between the blocking bars 904 during the downward rolling process due to their irregular shapes. The operation of the second motor 901 can drive the belt conveyor roller 902 to rotate, and the rotation of the belt conveyor roller 902 can drive the belt 903 to rotate in the direction opposite to the rolling direction of the seeds. Therefore, the trapped impurities will fall into the interior of the first impurity collection box 401 under the conveying action of the belt 903, so that small impurities can be collected. The provided blocking bars 904 are made of silica gel material, so the seeds will not be damaged by collision during the downward rolling process. The height of the provided blocking bars 904 is less than the diameter of the seeds and will not block the seeds. For some seeds with light weight and low inertia, the seeds will be blocked between the blocking bars 904. The seeds after the initial screening can fall onto the screening mesh 5. Then, under the action of the vibration motor 6, the seeds and large impurities can be quickly screened and separated. The selected seeds can fall into the interior of the fine product collection box 7, and the large impurities can fall into the interior of the second impurity collection box 8. The dust impurities raised during the screening process can be sucked away by the dust suction member 3, so that the cleanliness of the seed surface can be ensured.
