Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] Embodiment:

[0032] Please refer to Figures 1 - 5 , the present invention provides a uniform amount device for an agricultural planter, including a seed bin 1, windproof curtains 2 are installed on both sides of the bottom of the seed bin 1, a seeding and planting rotating part 3 is installed at the bottom of the seed bin 1, a bearing 4 is fixedly sleeved on the part of the seeding and planting rotating part 3 located outside the seed bin 1, an outer sleeve 5 is fixedly sleeved outside the bearing 4, a vibrator 6 is fixedly installed on the side of the outer sleeve 5, the end of the seeding and planting rotating part 3 is inserted and installed with a cylinder 7, the end of the inner rod of the cylinder 7 is inserted into the end of the seeding and planting rotating part 3, and the cavity of the cylinder 7 is fixedly connected to a motor 8.

[0033] Specifically, the length of the windproof curtain 2 is the same as the length of the seed bin 1, and the windproof effect is good.

[0034] Specifically, as Figure 5 shown, metal sheets 201 are installed at intervals on the side of the windproof curtain 2, and magnetic sheets 202 are fixedly installed at the bottom corner positions of the windproof curtain 2. Through the adsorption and fixation of the magnetic sheets 202 and the metal sheets 201, after the windproof curtain 2 is flipped and adjusted to the mopping length, the flipped-up part will not fall off.

[0035] Specifically, asFigure 1 , Figure 2 and Figure 3 As shown in Figure 3 , the seeding and planting rotating member 3 includes a shaft member 301, a collar 302, a seed groove 303, an external thread 304, a nut 305 and a docking card slot 306. The collar 302 is sleeved and installed on the shaft member 301. A seed groove 303 is formed on one side of the collar 302. External threads 304 are provided at both ends of the shaft member 301 outside the collar 302. Nuts 305 are installed at the positions of the external threads 304. The two nuts 305 clamp the collar 302. A docking card slot 306 is formed at the end of the shaft member 301. The end of the inner rod of the cylinder 7 is fitted and inserted into the docking card slot 306. The inner ring of the bearing 4 is sleeved and installed on the shaft body of the shaft member 301 outside the external thread 304. It can be adjusted according to the seeding spacing and the seeding amount of the seeds. The adjustment is convenient, and the nut 305 is used for fixation, and the operation is convenient.

[0036] Specifically, as Figure 3 As shown in Figure 3 , the opening of the seed groove 303 is flush with the top of the bottom opening of the seed bin 1 to prevent dead corners in the feeding and prevent the seeds from getting stuck on both sides of the seeding and planting rotating member 3.

[0037] Specifically, as Figure 3 As shown in Figure 3 , the docking card slot 306 is rectangular, and it is easy to be driven.

[0038] Specifically, as Figure 2 As shown in Figure 2 , the arc-shaped bayonet 101 on the side plate of the seed bin 1 is arranged against the upper part of the outermost collar 302. The nut 305 is located below the arc-shaped bayonet 101 on the side plate to limit the movement of the collar 302 and prevent the collar 302 from moving along the shaft member 301 to the outside of the seed bin 1.

[0039] Specifically, as Figure 4 As shown in Figure 4 , the outer sleeve 5 is semi-waist-shaped, and the vibrator 6 is fixed on the flat side of the outer sleeve 5, which is convenient for the installation of the vibrator 6.

[0040] Working principle:

[0041] First, according to the soil type, determine the row spacing for planting, and then determine the number of seeds to be planted at the seeding point positions within the determined spacing. At the same time, the size of the seed particles should also be taken into account;

[0042] After determining the above points, slightly loosen the nut 305 to allow the collar 302 to rotate on the shaft member 301, rotate the seed groove 303 upward. The spacing between the seed grooves 303 is the seeding spacing, and the capacity of the seed groove 303 controls the number of seeds sown. After adjustment, tighten the nuts 305 on both sides to fix them so that the collar 302 cannot loosen or turn;

[0043] According to the distance between the planter and the ground, the windbreak curtain 2 is turned and folded, and the metal sheet 201 and the magnetic sheet 202 are adsorbed and fixed to adjust the vertical length of the windbreak curtain 2. The end of the inner rod of the air cylinder 7 is inserted into the docking slot 306. In this way, the motor 8 drives the air cylinder 7 to rotate, and the air cylinder 7 drives the shaft member 301 to rotate through the docking slot 306. Since the end of the vibrator 6 is fixed to the outer sleeve 5, and the outer sleeve 5 is fixed to the bearing 4, when the shaft member 301 rotates, the vibrator 6 remains stationary. During sowing, the seed groove 303 rotates to the lower side, and the remaining seed grooves 303 need to be adjusted to a position where they do not enter the seed bin 1 after rotation. The excess seeds on the seed groove 303 are retained by the seed bin 1. After the seeds fall, the motor 8 drives the shaft member 301 to rotate reversely, and the seed groove 303 returns to its original position reversely;

[0044] When encountering material feeding jams, the end of the inner rod of the air cylinder 7 disengages from the docking slot 306, so that the shaft member 301 loses its limit, and the vibrator 6 vibrates slightly to achieve material discharging;

[0045] The vibrator 6 and the motor 8 are fixed to the frame or housing of the planter.

[0046] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
