Description

Technical Field

[0001] The utility model relates to the technical field of crop sowing, in particular to a crop sowing device. Background Art

[0002] Crop seeds are the core of agricultural planting and the foundation of crop production. Sowing is a critical step in agricultural cultivation, crucial for crop yield and quality. Before sowing, the soil needs to be plowed, leveled, fertilized, and irrigated to ensure good soil structure, adequate nutrients, and moisture. Based on the crop type and planting requirements, select the appropriate sowing method, ensuring the seed is planted at the appropriate depth and the appropriate soil cover thickness to meet crop growth requirements. Sowing density and spacing should be controlled according to the crop type and its growth characteristics. After sowing, timely irrigation and topdressing should be performed to ensure the nutrients necessary for crop growth.

[0003] Existing crop seed sowing generally adopts the manual sowing method, which is inefficient and labor-intensive. Some use mechanical sowing devices, which only perform the seed sowing step. Other steps such as raking, fertilizing and irrigation still need to rely on other devices or manual processing.

The partitions abut the inner wall of the seed storage box. The partitions are arranged in a circular array, with adjacent partitions forming a metering cavity. A drive assembly is provided on the flat plate, and seeds are moved out of the seed storage box through the metering cavity, the discharge port, and the discharge pipe. This utility model can sow seeds in a fixed quantity during sowing.

[0005] Although the device can sow seeds in a quantitative manner, it cannot adjust the amount of seeds sown each time, nor can it adjust the interval rate of sowing, which has certain limitations. Utility Model Content

[0033] Example

[0034] Please refer to Figure 1-Figure 2The utility model provides a crop sowing device, including a support plate 1, a driving device 2, a front wheel 3, a plowing structure 4, a quantitative sowing structure 5, a bulldozer structure 6, a water-fertilizer mixing structure 7, and an armrest 8.

[0035] Furthermore, the support plate 1 is used to place various crop sowing structures. The front end of the support plate 1 is provided with a front wheel 3, and the rear end of the support plate 1 is provided with a driving device 2 and an armrest 8. The driving device 2 and the front wheel 3 cooperate to drive the device to move, and the worker holds the armrest 8 to control the moving direction of the device.

[0036] Furthermore, the support plate 1 is provided with a plowing structure 4, a quantitative sowing structure 5, a bulldozer structure 6 and a water-fertilizer mixing structure 7 from the front end to the rear end, which carry out the complete sowing process of plowing furrows, sowing seeds, covering soil and watering fertilizers on the sowing land in sequence.

[0037] The plowing structure 4 includes a plowboard 401, which is vertically fixed on the support plate 1. When sowing, the bottom of the plowboard 401 is inserted into the sowing soil. Driven by the driving device 2, the soil is plowed to form a groove for sowing seeds (the sowing soil has been loosened in advance and can be used for direct sowing).

[0038] The quantitative sowing structure 5 includes a seed storage box 501, a conveying pipe 502, a connecting plate 503, a circular shell 504, a first motor 505, a rotating shaft 506, an internal disc 507, a seed storage cylinder 508, an electric cylinder 509, a seed inlet 510, and a seed outlet 511.

[0039] Specifically, the seed storage box 501 is set on the support plate 1 and is responsible for storing crop seeds. The bottom of the seed storage box 501 is connected to the delivery pipe 502. The bottom of the seed storage box 501 is provided with an inclined surface to facilitate the seeds to fall into the delivery pipe 502.

[0040] The other end of the delivery tube 502 is fixedly connected to the circular housing 504. A seed inlet 510 is provided above the circular housing 504. The pipeline of the delivery tube 502 is connected to the seed inlet 510 and is responsible for delivering seeds into the circular housing 504. The circular housing 504 is fixedly connected to the connecting plate 503, which is fixedly provided on the lower surface of the support plate 1.

[0041] Inside the circular housing 504, an internal disc 507 is coaxially rotated. A rotating shaft 506 is fixedly inserted through the center of the internal disc 507. The rotating shaft 506 is fixedly connected to the drive shaft of the first motor 505. The first motor 505 is fixed to the connecting plate 503. A seed storage cylinder 508 is fixedly mounted within the internal disc 507. Seeds entering the circular housing 504 are transported into the seed storage cylinder 508. The volume of the seed storage cylinder 508 is fixed, facilitating the delivery of a fixed amount of seeds.

[0042] The seed measuring cylinder 508 is connected to the electric cylinder 509, and the pushing end of the electric cylinder 509 passes through the bottom of the seed measuring cylinder 508. The pushing end of the electric cylinder 509 is provided with a plug, which is connected to the inner sliding seal of the seed measuring cylinder 508.

[0043] Preferably, by controlling the pushing distance of the electric cylinder 509, the volume inside the seed storage cylinder 508 can be accurately adjusted to store different quantities of seeds, thereby targeting the sowing quantity of different types of crop seeds.

[0044] A seed outlet 511 is provided below the circular shell 504. When the first motor 505 drives the seed measuring cylinder 508 to rotate from the seed inlet 510 to the seed outlet 511 by rotating the internal disc 507, the seeds stored in the seed measuring cylinder 508 fall out from the seed outlet 511. The seed outlet 511 faces the ground, so that the seeds fall into the soil groove plowed by the plow blade 401, thereby achieving sowing.

[0045] Among them, in the circular shell 504, except for the position where the seed storage measuring cylinder 508 is placed on the internal disc 507, the rest of the positions are solid discs. When the seed storage measuring cylinder 508 does not correspond to the seed inlet 510 and the seed outlet 511, the seed inlet 510 and the seed outlet 511 are blocked by the solid disc of the internal disc 507, and seeds cannot be stored or sown.

[0046] Furthermore, the bulldozer structure 6 includes a vertical plate 601 and a push plate 605. The vertical plate 601 is vertically fixed on the support plate 1. Two push plates 605 facing each other are provided at the bottom of the vertical plate 601. The two push plates 605 are combined into an eight-shaped shape, with the large opening of the eight-shaped shape facing the front end of the support plate 1 and the small opening of the eight-shaped shape facing the rear end of the support plate 1.

[0047] Preferably, when the front moldboard 401 plows a furrow, the plowed soil will be scattered to both sides of the furrow, and when the figure-eight-shaped push plate 605 moves to this position, the larger opening preferably contacts the scattered soil and slowly gathers the soil together through the figure-eight-shaped structure, while the smaller figure-eight-shaped opening can prevent the push plate 605 from pushing away all the soil, causing the gathered soil to be unable to cover the sown seeds, and a part of the soil will remain at the smaller opening.

[0048] Furthermore, the water-fertilizer mixing structure 7 includes a water tank 701, a fertilizer tank 702, a mixing tank 703, a water pipe 704 and a stirring assembly.

[0049] Specifically, the water tank 701 and the fertilizer box 702 are fixedly arranged on the top of the mixing box 703, and the bottom of the water tank 701 and the fertilizer box 702 are connected to the mixing box 703. The mixing box 703 is fixedly arranged on the support plate 1. A stirring assembly is provided in the mixing box 703. The bottom of the mixing box 703 is connected to the water pipe 704, and the bottom of the water pipe 704 faces the ground.

[0050] After the bulldozer structure 6 covers the soil ditch, the sown soil needs to be watered or fertilized, so water and fertilizer are mixed into the mixing box 703, stirred evenly by the stirring assembly, and then dripped into the sowing area through the water pipe 704 for watering or fertilizing.

[0051] It is worth noting that a valve switch is also provided at the end of the water pipe 704 , and the valve switch can be twisted to adjust the flow rate of the water dripping out of the water pipe 704 .

[0052] In a feasible embodiment, the stirring assembly includes a second motor 705 and a stirring rod 706 .

[0053] The second motor 705 is fixedly installed below the support plate 1. The drive shaft of the second motor 705 vertically passes through the support plate 1 and the bottom of the mixing box 703, is fixedly connected to the stirring rod 706 inside the mixing box 703, and drives the stirring rod 706 to rotate, thereby mixing the water and fertilizer in the mixing box 703 together.

[0054] Please refer to Figure 2 In a feasible embodiment, the moldboard 401 in the plowing structure 4 can be adjusted in height vertically to plow soil furrows of different depths to adapt to the sowing depths of different seeds.

[0055] The plowing structure 4 further includes a first limiting groove 402 , a first clamping plate 403 , and a first clamping block 404 .

[0056] Specifically, the plowboard 401 and the support plate 1 are arranged to slide vertically, the first limit groove 402 passes through the plowboard 401, and multiple first limit grooves 402 are arranged vertically on the plowboard 401. A first clamping plate 403 is provided on the first limit groove 402 for horizontal sliding. The first clamping plate 403 is located on the upper surface of the support plate 1, and first clamping blocks 404 are slidingly provided at both ends of the first clamping plate 403. The first clamping block 404 is fixedly installed on the upper surface of the support plate 1.

[0057] When the furrow depth needs to be adjusted, the plowboard 401 is moved vertically to a certain height, and then the first clamping plate 403 is inserted into the first limiting groove 402 on the upper surface of the support plate 1. The movement of the first clamping plate 403 is limited by the first clamping block 404, thereby adjusting the furrow depth of the plowboard 401.

[0058] Please refer to Figure 2 In a feasible embodiment, the bulldozing structure 6 also needs to adjust different bulldozing heights according to the moldboards 401 of different heights.

[0059] The bulldozer structure 6 further includes a second limiting groove 602 , a second clamping plate 603 , a second clamping block 604 , and a pushing plate 605 .

[0060] Specifically, the vertical plate 601 and the support plate 1 are arranged to slide vertically, the second limiting groove 602 passes through the vertical plate 601, and multiple second limiting grooves 602 are arranged vertically on the vertical plate 601. A second clamping plate 603 is provided on the second limiting groove 602 for horizontal sliding. The second clamping plate 603 is located on the upper surface of the support plate 1, and second clamping blocks 604 are slidingly provided at both ends of the second clamping plate 603. The second clamping block 604 is fixedly installed on the upper surface of the support plate 1.

[0061] When following the moldboard 401 to adjust the height of the push plate 605, the vertical plate 601 is moved vertically to a certain height, and then the second clamping plate 603 is inserted into the second limiting groove 602 on the upper surface of the vertical plate 601. The movement of the second clamping plate 603 is limited by the second clamping block 604, thereby adjusting the push height of the push plate 605.

[0062] Please refer to Figure 3-Figure 4 In a feasible embodiment, a plurality of seed measuring cylinders 508 and electric cylinders 509 are arranged along the circumference of the axis within the inner disc 507.

[0063] Preferably, when the inner disc 507 rotates, it drives the seed cylinder 508 to rotate, and multiple seed cylinders 508 can be set to increase sowing efficiency. Each seed cylinder 508 is individually connected to an electric cylinder 509, and there is a solid inner disc 507 between adjacent seed cylinders 508. When multiple seed cylinders 508 rotate, a fixed amount of seeds will only enter the seed cylinder 508 that rotates to the seed inlet 510, achieving spaced sowing.

[0064] When the sowing rate needs to be adjusted, the sowing rate can be adjusted by controlling the number of electric cylinders 509 in the positions and closing the corresponding seed measuring cylinders 508 (the electric cylinders 509 for the closing work need to be arranged in a uniform circular arrangement to ensure the same sowing rate of the device).

[0065] Please refer to Figure 2 In a feasible embodiment, the driving device 2 includes a fixing frame 201 and a driving wheel set 202 .

[0066] Specifically, the top of the fixing frame 201 is fixedly connected to the lower surface of the support plate 1, and the bottom of the fixing frame 201 is rotatably provided with a driving wheel group 202, which includes wheels, rollers connected to the wheels, and a driving motor on the rollers.

[0067] The front wheel 3 includes a support column 301 and a universal wheel 302. The universal wheel 302 is arranged at the bottom of the support column 301. The upper part of the support column 301 is provided with a thread. The support column 301 vertically passes through the support plate 1. The support column 301 is threadedly matched with the support plate 1.

[0068] When the device moves on the road, the wheels of the universal wheel 302 and the driving wheel group 202 are in contact with the ground, driving the device to move. When the device enters the sowing land for sowing, the support column 301 is rotated so that the support column 301 moves up through the thread to avoid interfering with the plowing work of the plow plate 401 at the front end of the support plate 1 (the wheel surface of the universal wheel 302 is wider, and moving in the sowing soil will destroy the looseness of the soil, making plowing more difficult, while the wheel surface of the driving wheel group 202 is narrower and the impact is smaller).

[0069] In a feasible embodiment, the plowboard 401 , seed outlet 511 , figure-eight push plate 605 and water pipe 704 are sequentially arranged along the front and rear ends of the support plate 1 , and at least two groups are arranged along the left and right directions of the support plate 1 .

[0070] Preferably, by arranging multiple groups of sowing structures, multiple rows of crop seeds can be sown simultaneously, thereby improving sowing efficiency.

[0071] Thus far, various embodiments of the present invention have been described in detail. To avoid obscuring the concept of the present invention, some details known in the art have been omitted.
