DETAILED DESCRIPTION

[0045] In order to make the purpose, technical solution and advantages of this technical solution more clear, the following technical solution is further described in detail in conjunction with specific implementation methods. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of this technical solution.

[0046] See also Figures 1 to 9 A rapid seed and grain screening device for use in a laboratory comprises a main body 1, wherein the main body 1 comprises a workbench 11 and a body 12, wherein legs 111 are provided at the four corners of the bottom end of the workbench 11, and the body 12 is arranged at the front end of the upper surface of the workbench 11;

[0047] The front end of the machine body 12 is provided with a feed hopper 2 via a mounting bracket;

[0048] A sieve tray 3 that can swing left and right is provided on the upper surface of the body 12 at the rear end of the feed hopper 2. The sieve tray 3 is tilted and arranged on the upper surface of the body 12, with the front end of the sieve tray 3 higher than the rear end. A plurality of vertical first grooves 31 are provided on the upper end of the sieve tray 3, and first guard plates 32 are symmetrically provided on the left and right edges of the sieve tray 3.

[0049] A feed plate 4 is provided on the upper surface of the body 12 at the rear end of the sieve plate 3. The feed plate 4 is tilted and arranged on the upper surface of the body 12. The front end of the feed plate 4 is higher than the rear end, and the front end of the feed plate 4 is in close contact with the rear end of the sieve plate 3. A plurality of vertical second grooves 41 are formed on the upper end surface of the feed plate 4. Second guard plates 42 are symmetrically provided on the left and right edges of the feed plate 4.

[0050] A conveyor belt 5 is provided on the upper surface of the workbench at the rear end of the machine body 12. The front end of the conveyor belt 5 is located below the rear end of the feed plate 4. Third guard plates 51 are symmetrically provided on the outer edges of the left and right sides of the conveyor belt 5.

[0051] A breaking mechanism 6 is provided in the feed hopper 2;

[0052] The breaking up mechanism 6 includes a first breaking up component and a second breaking up component.

[0053] The first disintegrating assembly includes a rotating shaft 61 and a first disintegrating rod 62. The rotating shaft 61 is rotatably arranged inside the feed hopper 2, and the rotating shaft 62 is parallel to the feed hopper 2. One end of the rotating shaft 61 passes through the side wall of the feed hopper 2 and is connected to a driving member outside the feed hopper 2 (not shown in the figure, so no further details are given). The rotating shaft 61 is driven to rotate by the driving member, and the first disintegrating rods 62 are evenly distributed on the outer surface of the rotating shaft 61.

[0054] The second breaking up assembly includes a mounting plate 63 and a second breaking up rod 64. Figure 7 and Figure 8 As shown, the mounting plate 63 is fixedly arranged on the inner wall of the feed hopper 2, the second breaking up rods 64 are evenly arranged on the side wall of the mounting plate 63 opposite to the first breaking up assembly, and the second breaking up rods 64 are perpendicular to the mounting plate 63, and the second breaking up rods 64 and the first breaking up rods 62 are staggered.

[0055] When the sample is poured into the feed hopper, the driving member drives the rotating shaft 61 to rotate, and then drives the first breaking rods 62 to rotate, breaking up the agglomerated sample. This not only prevents the agglomerated sample from blocking the outlet, but also enables the selection personnel to select the diseased samples as much as possible, thereby improving efficiency.

[0056] Further, such as Figure 5 and Figure 7As shown, an adjustment mechanism 7 is provided inside the feed hopper 2 below the breaking mechanism 6, including a fixing rod 71, an adjusting plate 72 and a screw 73. The fixing rod 71 is fixedly installed in the feed hopper 2 between the left and right side walls, the upper end of the adjusting plate 72 is rotatably connected to the fixing rod 71, and the upper end of the adjusting plate 72 is smoothed. When the adjusting plate 72 is rotated at will, the upper end of the adjusting plate 72 is always in close contact with the front inner wall of the feed hopper 2. A through hole 21 is provided on the front side wall of the feed hopper 2. The through hole 21 is perpendicular to the front side wall of the feed hopper 2, and an internal thread 211 is provided on the inner wall of the through hole 21. The screw 73 is threadedly connected and arranged in the through hole 21, and the end of the screw 73 close to the adjusting plate 72 is a hemispherical structure. When the rotation angle of the adjusting plate 72 is changed by rotating the screw 73, one end of the screw 73 is always in contact with the side wall of the adjusting plate 72.

[0057] By rotating the screw 73, the end of the screw 73 in contact with the adjusting plate 72 pushes the adjusting plate 72 to rotate, thereby changing the size of the gap between the adjusting plate 72 and the rear side wall of the bottom of the feed hopper 2, thereby achieving the speed and quantity of the sample flowing out of the bottom of the feed hopper 2.

[0058] Further, such as Figure 4 As shown, the upper surface of the front end of the body 12 is located below the feed hopper 2 and is provided with a guide plate 8. The length of the guide plate 8 is greater than the length of the feed hopper 2, and the front end of the guide plate 8 is higher than the rear end of the guide plate 8. The left and right edges of the guide plate 8 are symmetrically provided with limit baffles 81, and the rear end of the guide plate 8 is in contact with the front end of the sieve plate 3. When the sample falls onto the guide plate 8 through the bottom outlet of the feed hopper 2, the inclined guide plate 8 can allow the sample to smoothly enter the first groove 31 of the sieve plate 3.

[0059] Further, such as Figure 1 、 Figure 2 and Figure 9 As shown, a collecting box 9 is provided at the rear end of the conveyor belt 5. The opening of the collecting box 9 is located below the rear end of the conveyor belt 5, and the length of the collecting box 9 is greater than the width of the conveyor belt 5. A vertical scraper 10 is provided inside the collecting box 9. The side walls of the scraper 10 are in close contact with the inner wall of the collecting box 9, and the upper end of the scraper 10 is higher than the upper end of the collecting box 9. Sliders 101 are respectively installed on the upper and lower parts of the front and rear side walls of the scraper 10. The upper and lower parts of the front and rear inner walls of the collecting box 9 are respectively provided with slide grooves 91 matching the sliders 101. By pulling the scraper 10, the scraper 10 is moved in the collecting box 9, and the samples scattered in the collecting box 9 are gathered to one end of the collecting box 9, which is convenient for the collector to take out the samples in the collecting box 9.

[0060] like Figure 4As described, a power switch A, a first adjustment button B and a second adjustment button C are respectively provided on the outer wall of the body 12. The power switch A can control the power of the entire device. The first adjustment button B is connected to the control mechanism of the sieve plate 3 (not drawn in the figure, so no further details are given). By twisting the first adjustment button B, the speed of the sieve plate 3 shaking left and right can be changed. The speed adjustment range of the first adjustment button B is 0-6 gears, gear 0 is off, and gear 6 is maximum; the second adjustment button C is connected to the control mechanism of the conveyor belt 5 (not drawn in the figure, so no further details are given). By twisting the second adjustment button C, the moving speed of the conveyor belt 5 can be changed. The speed adjustment range of the second adjustment button C is 0-6 gears, gear 0 is off, and gear 6 is maximum.

[0061] Working principle:

[0062] Turn on the power switch A, twist the first adjustment button B to adjust the speed of the sieve plate 3, twist the second adjustment button C to adjust the speed of the conveyor belt 5, then start the scattering mechanism 6, and pour the sample into the feed hopper 2. Since the feed hopper 2 can hold a maximum of about 2 kg of samples, a large number of samples can be poured into the feed hopper 2 in batches. The sample passes through the scattering mechanism 6 and falls into the first grooves 31 of the sieve plate 3 from the outlet at the bottom of the feed hopper 2 through the guide plate 8. As the sieve plate 3 shakes, the sample gradually passes through the second grooves 41 of the feed plate 4 and falls onto the conveyor belt 5. As the conveyor belt 5 rotates, the selecting personnel can quickly screen on the conveyor belt 5. The selected samples fall directly into the collecting box 9 with the movement of the conveyor belt 5 for sample recovery. When selecting samples, if it is necessary to control the speed and quantity of the sample flowing out of the bottom outlet of the feed hopper 2, the screw 73 can be rotated to change the rotation angle of the adjusting plate 72, thereby changing the gap between the adjusting plate 72 and the bottom wall of the discharge hopper 2.

[0063] The above content is only a preferred embodiment of the present invention. For ordinary technicians in this field, many changes can be made in the specific implementation methods and application scope based on the ideas of the present technical content. As long as these changes do not deviate from the concept of the present invention, they all fall within the scope of protection of this patent.
