[0031] The utility model relates to the technical field of seed screening, and in particular to a portable seed screening device. The purpose is to solve the problems of the existing seed screening device being inconvenient to carry, having a complex structure, being restricted by the site, and having a high cost. To this end, the portable seed screening device provided by the utility model comprises a handpiece and a gathering piece, wherein at least one gathering piece is detachably fixedly connected to the handpiece, and a plurality of tooth pins arranged at equal intervals along the length direction of the gathering piece are detachably fixedly connected to the gathering piece, and the spacing between adjacent tooth pins is used for seeds to pass through.

At the same time, the tooth pins can be adjusted to the installation position on the gathering piece through the detachable fixed connection mode, thereby realizing the adjustment of the spacing between two adjacent tooth pins, so that seeds of different sizes can pass through when screening seeds, and the purpose of screening multiple seeds of different sizes is realized. The overall structure is simple, not limited by the working occasion, and the cost is low. It can meet the needs of one person, and can be used in conjunction with a counter. In particular, when the number of seeds is small, it can be combined with manual counting to achieve the purpose of quickly counting the number of seeds.

[0032] The portable seed screening device provided by the embodiment of the utility model is described in detail below with reference to the accompanying drawings.

[0033] See also Figure 1-3 The utility model provides a portable seed screening device, including a handheld piece 2 and a gathering piece 1, wherein at least one gathering piece 1 is detachably fixedly connected to the handheld piece 2, and a plurality of tooth nails 12 arranged at equal intervals along the length direction of the gathering piece 1 are detachably fixedly connected to the gathering piece 1, and the spacing between adjacent tooth nails 12 is used for seeds to pass through.

[0034] In one embodiment, the gathering piece 1 is in a crescent shape, and the shape formed by the arrangement of the plurality of tooth pins 12 is the same as the gathering piece 1. The gathering piece 1 is in a crescent shape, and the plurality of tooth pins 12 are arranged to form a crescent shape. When the handpiece 2 is manually operated to drive the tooth pins 12 on the gathering piece 1 to screen the seeds, the seeds can be gathered, thereby avoiding the problem that the seeds are dispersed outside the gathering area during the screening process and cannot be screened, which helps to improve the screening efficiency.

[0035] In one embodiment, the gathering sheet 1 is provided with a plurality of first connection holes 3 arranged at equal intervals along its length direction, and the tooth pins 12 are detachably fixedly connected to the first connection holes 3 .

[0036] In one embodiment, see Figure 1 and Figure 3The tooth nail 12 is a cylindrical structure, and the top of the tooth nail 12 is integrally formed with a first stud 11, and the first stud 11 is threadedly connected with a nut 10. The diameter of the tooth nail 12 is greater than the diameter of the first connection hole 3. After the first stud 11 passes through the first connection hole 3, it is connected with the nut 10 to press the gathering piece 1 between the tooth nail 12 and the nut 10. The gathering piece 1 is squeezed between the nut 10 and the tooth nail 12 by locking the nut 10 and the first stud 11 to achieve a fixed connection. The spacing between adjacent tooth nails 12 is used for seeds to pass through. According to the different sizes of the screened seeds, the spacing between adjacent tooth nails 12 is adaptively adjusted.

[0037] It should be noted that, although in the above description the tooth pin 12 is fixed to the gathering piece 1 by connecting the first stud 11 and the nut 10, this is not restrictive, and the connection structure between the tooth pin 12 and the gathering piece 1 can also be other structures. For example, the top of the tooth pin 12 is connected to the first connecting hole 3 by a snap-on structure. Specifically, a sphere is provided at the top of the tooth pin 12, and a U-shaped opening is provided in the middle part of the sphere. The diameter of the sphere is slightly larger than the diameter of the first connecting hole 3, for example, 0.5 to 1.5 mm larger. When the tooth pin 12 is installed, the sphere directly passes through the first connecting hole 3 under the action of external force, thereby realizing the snap-on connection between the tooth pin 12 and the gathering piece 1, which is also within the protection scope of the present utility model.

[0038] In the above embodiment, the tooth nails 12 can adjust the installation position on the gathering plate 1 through a detachable fixed connection method, thereby realizing the adjustment of the distance between two adjacent tooth nails 12, so that seeds of different sizes can be passed when screening seeds, thereby achieving the purpose of screening seeds of multiple different sizes.

[0039] In one embodiment, see Figure 1 The hand piece 2 includes a hand grip 21 and a gathering piece connecting piece 22. The gathering piece connecting piece 22 is detachably connected to one end of the hand grip 21, and the gathering piece connecting piece 22 can be flipped relative to the hand grip 21. One end of the gathering piece 1 is detachably fixedly connected to the gathering piece connecting piece 22. The angle between the gathering piece connecting piece 22 and the hand grip 21 can be adjusted, so that the staff can find an angle suitable for their operation when holding the hand grip 21 for screening, thereby improving the comfort of use.

[0040] In the first specific implementation, see Figure 4 Two connecting seats 7 are provided on the gathering piece connecting piece 22, and each connecting seat 7 is provided with a second connecting hole. A rotating shaft 6 is fixed to one end of the handle 21, and the axis of the rotating shaft 6 is perpendicular to the axis of the handle 21. One end of the handle 21 is located between the two connecting seats 7 and the end of the rotating shaft 6 is inserted into the adjacent second connecting hole. A plurality of circumferentially distributed third connecting holes are provided on the outer peripheral wall of the rotating shaft 6. The connecting seat 7 is threadedly connected to one of the third connecting holes by a screw 8 to fix the rotating shaft 6.

[0041] Specifically, a fourth connecting hole is provided on the connecting seat 7, and the center line of the fourth connecting hole is perpendicular to the center line of the second connecting hole. The screw 8 passes through the fourth connecting hole and is connected to a third connecting hole on the rotating shaft 6, thereby realizing a detachable fixed connection between the handle 21 and the gathering piece connecting piece 22. When it is necessary to adjust the angle of the handle 21 relative to the gathering piece connecting piece 22, it is only necessary to remove the screw 8 and connect it to the third connecting hole on the other rotating shaft 6. The adjustment method is simple and convenient.

[0042] In the second specific embodiment, see Figure 5 A ball joint 17 is fixed on the gathering piece connecting piece 22, and a fixing ring 14 is threadedly connected to the outer side of the ball joint 17. A connecting ball 16 is fixed to one end of the hand handle 21, and the connecting ball 16 is inserted into the ball joint 17 and locked by the fixing ring 14.

[0043] Specifically, at least three evenly distributed notches 15 are provided on the ball connection groove 17. After the connecting ball 16 is inserted into the ball connection groove 17, tightening the fixing ring can close the notches 15, thereby limiting the connecting ball 16 in the ball connection groove 17. Continuing to tighten can fix the connecting ball 16 in the ball connection groove 17. When the angle of the hand grip 21 needs to be adjusted, the fixing ring 14 can be loosened, and after the angle is adjusted, it can be tightened to achieve the function of fixing the angle of the hand grip 21 by fixing the connecting ball 16. Due to the ball hinge connection between the connecting ball 16 and the ball connection groove 17, a multi-angle swing function is achieved. Compared with the first specific embodiment, the swing angle is more flexible, so this embodiment is used as the preferred embodiment of the present application.

[0044] In one embodiment, the number of the gathering pieces 1 is at least two, and they are distributed side by side along the length direction of the gathering piece connecting piece 22 .

[0045] It should be noted that the number of the gathering pieces 1 can be adjusted according to on-site needs, that is, the gathering pieces 1 can be used alone, or in two or three pieces. According to the size of the seeds, graded screening can be carried out to screen seeds of different sizes multiple times or simultaneously to determine suitable sowing conditions for sowing, ensure uniform growth of seeds in the later stage, and facilitate unified management. The gathering piece 1 is crescent-shaped, which is convenient for gathering seeds together when screening seeds to avoid dispersion and affect seed screening.

[0046] In one embodiment, see Figure 2 and Figure 4 A clamping block 4 is fixed at one end of the gathering piece 1, and a plurality of clamping slots 9 are arranged along its length direction on the gathering piece connecting piece 22. The clamping block 4 and the clamping slot 9 are T-shaped structures that cooperate with each other, and the bottom end of the clamping slot 9 is provided with an opening, and the top end is a closed structure. The clamping block 4 moves upward from the opening to be inserted into the clamping slot 9 and is clamped.

[0047] In the above embodiment, in order to make the block 4 clamped in the clamping slot 9, a rubber pad is bonded on the inner wall of the clamping slot 9 to ensure that the clamping does not shake. The top of the clamping slot 9 is a closed structure, that is, after the block 4 is inserted into the clamping slot 9, it abuts against the top of the clamping slot 9 and cannot move upward, ensuring that the gathering piece 1 does not move upward when screening seeds. The gathering piece 1 and the gathering piece connector 22 are detachably fixedly connected by a clamping method, and the clamping structure is simple and easy to operate.

[0048] In one embodiment, the handle 21 is a hollow cylinder, and the other end of the handle 21 is provided with a storage port connected to the inside, and the storage port is threadedly connected with a cap 5. In order to increase the friction of the handle 21, a curved pattern is provided on the outer wall of the handle 21, which is easy to firmly grasp the handle 21. The handle 21 is a hollow structure inside, which can store the tooth nails 12 and play a role in storing the tooth nails 12 to prevent the tooth nails 12 from being lost due to nowhere to be placed during work. It can also be stored in the handle 21 as a spare tooth nail 12, which is convenient for subsequent use. Of course, a separate storage box for the tooth nail 12 can also be provided to store the backup tooth nail 12 to prevent the loss of the tooth nail 12 and affect the seed screening.

[0049] In one embodiment, see Figure 6 The seed screening device further comprises a storage box 13 , in which the hand piece 2 and the gathering sheet 1 are placed, and a storage portion for the tooth nail 12 is provided in the storage box 13 for storing the tooth nail 12 .

[0050] Specifically, the storage box 13 includes a cover body 132 and a box body 131, and the cover body 132 and the box body 131 are connected by a lock. A placement groove 133 is provided in the box body 131 for placing the gathering sheet 1, the gathering sheet connecting piece 22 and the handle 21, and the placement groove 133 has the same shape as the correspondingly placed gathering sheet 1, the gathering sheet connecting piece 22 and the handle 21.

[0051] The specific operating principle of the utility model is: after the gathering piece 1, the gathering piece connecting piece 22, the tooth nails 12 and the hand handle 21 are assembled and installed, the hand handle 21 drives the gathering piece 1 to make the tooth nails 12 move with it to screen seeds. During the movement, the seeds that meet the requirements pass through the gaps between adjacent tooth nails 12, and the seeds that do not meet the requirements cannot pass through, thereby realizing the seed screening operation by moving the gathering piece 1.

[0052] The seed screening device designed by the utility model can pre-screen the received seeds, and those that do not meet the requirements can be removed, which reduces the number of seeds subsequently counted by a seed counter, and helps to improve the efficiency of seed counting. In addition, the seed screening device designed by the utility model has a simple overall structure, is not limited by the working environment, has low cost, can be used by one person, can be used in conjunction with a counter, and especially when the number of seeds is small, can be combined with manual counting to achieve the purpose of quickly counting the number of seeds. The various components can be stored in a storage box for easy carrying.

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
