Description

Technical Field

[0001] This invention relates to the field of agricultural seeding machinery technology, specifically to a multi-compartment automatic seed supply and distribution device for rapeseed plot breeding. Background Technology

[0002] In modern agricultural planting, the seed supply system of a seeder is a key component affecting the quality and efficiency of sowing. Currently, most seed supply devices on the market use a centralized seed box in conjunction with a mechanical or pneumatic seed metering device. While this can meet the basic needs of field operations, it still has significant shortcomings in precision operations such as small-scale breeding and alternating sowing of multiple varieties.

[0003] Traditional seed supply devices often have the following problems: First, the process of changing seeds requires manual operation and shutdown, which seriously affects the continuity of operations; second, seeds are prone to damage or blockage during transportation; third, when switching between multiple seed varieties, mixing can easily occur, affecting the purity of the experiment; and fourth, the complex structure and high maintenance costs make it difficult to promote and use.

[0004] Although some multi-compartment, clip-on, and box-type seed supply devices have been proposed, such as the chain-driven seed box propulsion mechanism used in some small-area seeders, they still have problems such as inaccurate propulsion, easy jamming of the seed box, and incomplete seed separation, which cannot meet the needs of high-speed and high-precision sowing. Therefore, there is an urgent need for a new type of device with a reasonable structure, simple operation, and the ability to achieve automated continuous seed supply and separation. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a multi-compartment automatic seed supply and distribution device for rapeseed plot breeding planters, which can realize automatic switching, precise delivery and uniform distribution of multiple varieties of seeds, so as to meet the operational needs of plot breeding and precision sowing.

[0006] The technical solution of the present invention to solve the above-mentioned technical problems is as follows:

[0007] A multi-compartment automatic seed supply and distribution device for rapeseed plot breeding includes a base plate, a fixed base, a multi-compartment seed box, a seed container, a seed box moving assembly, a seed container moving assembly, a container opener, a recycling bin, and a distribution assembly. The base plate has a fixed base at its bottom for fixed connection to a seeder frame. The base plate has a seed box moving assembly with a multi-compartment seed box. Each seed box has multiple rows of storage compartments arranged side-by-side, each containing multiple seed containers stacked inside. Each seed container stores rapeseed seeds. Each storage compartment has a discharge port at its bottom. The base plate also has a seed container moving assembly and a distribution assembly. The distribution assembly has a container opener at its input end. The seed box opener output end is equipped with a recycling bin. The seed box moving component is used to push the seed box out of the storage bin and push it to the opener, so that the seed box moves along the opener, opens the seed box, and pushes the empty seed box to the recycling bin. The seed box moving component is used to drive the seed box to move horizontally after the seed box in the previous storage bin is pushed out, so that the next storage bin is located directly in front of the seed box moving component. The opener is located directly above the seed distribution component. After the opener opens the seed box, the seeds can fall into the seed distribution component. The seed box moving component is also used to push the empty seed box to the recycling bin. The seed distribution component is used to evenly distribute the seeds to the seed metering device of the seeder after receiving the seeds. The base plate is equipped with a controller, which is used to control the linkage between the seed box moving component and the seed box moving component.

[0008] Furthermore, the seed box moving assembly includes a first electric push rod, a second electric push rod, and a slide rail. Two first electric push rods are symmetrically arranged on the base plate, and the two first electric push rods are respectively vertically installed on opposite sides of the two multi-compartment seed boxes. The push head of the first electric push rod can enter the inner side of the storage compartment through the box outlet. The intersection of the push head of the first electric push rod and the box outlet is the box pushing position. A second electric push rod is horizontally arranged between the two multi-compartment seed boxes. A slide rail is provided on the base plate between the push head of the second electric push rod and the box opener. The left and right input ends of the slide rail are respectively in contact with the two multi-compartment seed boxes. The first electric push rod is used to push the seed box at the box pushing position through the box outlet to the slide rail. The second electric push rod is used to push the seed box on the slide rail to the box opener after the first electric push rod resets, so that the seed box moves along the box opener, opens the seed box, and pushes the empty seed box to the recycling bin. The first electric push rod is also used to push the next seed box after the second electric push rod resets. The first electric push rod and the second electric push rod are alternately pushed in a cycle by the controller.

[0009] Furthermore, the seed box moving assembly includes double slide rails, a gear and rack mechanism, a motor, and baffles. Two double slide rails are symmetrically arranged on the base plate. The multi-compartment seed box is slidably connected to the double slide rails. U-shaped baffles are symmetrically arranged at the front and rear ends of the double slide rails. In the initial position, the rear side of the multi-compartment seed box abuts against the rear U-shaped baffle. When the rear side of the multi-compartment seed box abuts against the rear U-shaped baffle, the outlet of the foremost storage compartment is in the push-box position. When the front side of the multi-compartment seed box abuts against the front U-shaped baffle, the outlet of the rearmost storage compartment is in the push-box position. A gear and rack mechanism is horizontally arranged below the outlet on the opposite side of each of the two multi-compartment seed boxes. A motor for driving the gear and rack mechanism is provided on the base plate. The motor drives the first electric push rod to push once, and then moves the multi-compartment seed box forward one storage compartment position through the double slide rails and the gear and rack mechanism.

[0010] Furthermore, the seed distribution component includes a seed box, a seed guide tube, a seed distributor, and a fan. The seed box, which is funnel-shaped, is embedded in the bottom plate at the output end of the slide. The seed box opener is horizontally installed at the top opening of the seed box. A seed guide tube is provided at the bottom output end of the seed box, and a seed distributor is provided at the output end of the seed guide tube. A fan is provided below the bottom, and the output end of the fan is connected to the seed guide tube. The fan is used to transport rapeseed seeds to the seed distributor by blowing air. The seed distributor is used to evenly distribute rapeseed seeds to multiple seed metering devices of the seeder.

[0011] Furthermore, the upper part of the box opener is a wedge-shaped plate, which is used to cut open the seed box. Support rods are horizontally arranged on the left and right sides of the wedge-shaped plate, which are used to support and guide the seed box to slide along the support rods to retrieve the box.

[0012] The beneficial effects of this invention are as follows: by setting multiple rows of storage compartments in the seed box, and in conjunction with the seed box conveying component, the seed box opener and the seed dispensing component, the automatic switching, precise delivery and uniform distribution of rapeseed seeds of multiple varieties are realized; the whole device has a compact structure and is easy to operate, which can effectively improve the automation level and operation accuracy of sowing operations. It is particularly suitable for rapeseed small-scale breeding and multi-variety precision sowing operations, and has high practical value and promotion prospects. Attached Figure Description

[0019] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0020] like Figure 1-4 As shown, a multi-compartment automatic seed supply and distribution device for rapeseed plot breeding includes a base plate 1, a fixed base 2, a multi-compartment seed box 3, a seed container 4, a seed box moving assembly 5, a seed container moving assembly 6, a container opener 7, a recycling bin 8, and a distribution assembly 9. The base plate 1 has a fixed base 2 at its bottom, which is used to fix it to the seeder frame. The base plate 1 has a seed box moving assembly 5, which has a multi-compartment seed box 3. The multi-compartment seed box 3 has multiple rows of storage compartments arranged side-by-side inside, each storage compartment having multiple seed containers 4 stacked inside. Each seed container 4 stores rapeseed seeds inside, and each storage compartment has a discharge port at its bottom. The base plate 1 has a seed container moving assembly 6 and a distribution assembly 9, with a container opener at the input end of the distribution assembly 9. 7. The output end of the seed box opener 7 is provided with a recycling bin 8. The seed box moving component 6 is used to push the seed box 4 out of the storage bin and push it to the seed box opener 7, so that the seed box 4 moves along the seed box opener 7, opens the seed box 4 and pushes the empty seed box to the recycling bin 8. The seed box moving component 5 is used to drive the seed box to move horizontally after the seed box 4 in the previous storage bin is pushed out, so that the next row of storage bins is located directly in front of the seed box moving component 6. The seed box opener 7 is located directly above the seed distribution component 9. After the seed box opener 7 opens the seed box 4, the seeds can fall into the seed distribution component 9. The seed box moving component 6 is also used to push the empty seed box 4 to the recycling bin 8. The seed distribution component 9 is used to evenly distribute the seeds to the seed metering device of the seeder after receiving the seeds. The base plate 1 is provided with a controller, which is used to control the linkage between the seed box moving component 5 and the seed box moving component 6.

[0021] Specifically, the seed box has external dimensions of 450mm×150mm×500mm and internally has 4 rows of compartments, each row accommodating 10 seed boxes 4. The internal dimensions of seed box 4 are 80mm×60mm×30mm, and the capacity of a single box is approximately 100g of seeds.

[0022] In one embodiment, the seed box moving assembly 6 includes a first electric push rod 601, a second electric push rod 602, and a slide rail 603. Two first electric push rods 601 are symmetrically arranged on the base plate 1, and are vertically mounted on opposite sides of two multi-compartment seed boxes 3. The push head of the first electric push rod 601 can enter the inner side of the storage compartment through the box outlet. The intersection of the push head of the first electric push rod 601 and the box outlet is the box-pushing position. A second electric push rod 602 is horizontally arranged between the two multi-compartment seed boxes 3. A slide rail 603 is provided on the base plate 1 between the push head of the second electric push rod 602 and the box opener 7. The slide 603 has two input ends on its left and right sides that are in contact with two multi-compartment seed boxes 3. The first electric push rod 601 is used to push the seed box 4 at the push box position through the box outlet to the slide 603. The second electric push rod 602 is used to push the seed box 4 on the slide 603 to the box opener 7 after the first electric push rod 601 is reset, so that the seed box 4 moves along the box opener 7, opens the seed box 4 and pushes the empty seed box to the recycling box 8. The first electric push rod 601 is also used to push the next seed box 4 after the second electric push rod 602 is reset. The first electric push rod 601 and the second electric push rod 602 are pushed alternately and cyclically by the controller.

[0023] Specifically, the first starting push rod is mounted on the push rod support for elevation and fixation, and cooperates with the slide 603 of the seed box 4. Its stroke is 150mm, which is used to push the bottom seed box 4 in the seed box horizontally to the entrance of the slide 603. The stroke of the rear push rod is 250mm, which is used to push the seed box 4 along the slide 603 to the position of the box opener 7. The slide 603 has a U-shaped guide groove structure and limit plates on both sides to prevent the seed box 4 from shifting.

[0024] In one embodiment, the seed box moving assembly 5 includes double slide rails 501, a gear and rack mechanism 502, a motor 503, and baffles 504. Two double slide rails 501 are symmetrically arranged on the base plate 1. The multi-compartment seed box 3 is slidably connected to the double slide rails 501. U-shaped baffles 504 are symmetrically arranged at both ends of the double slide rails 501. In the initial position, the rear side of the multi-compartment seed box 3 abuts against the rear U-shaped baffle 504. When the rear side of the multi-compartment seed box 3 abuts against the rear U-shaped baffle 504, the outlet of the foremost storage compartment is... At the push box position, when the front side of the multi-compartment seed box 3 abuts against the front U-shaped baffle 504, the outlet of the last storage compartment is located at the push box position; both of the two multi-compartment seed boxes 3 have a gear and rack mechanism 502 horizontally arranged below the outlet on opposite sides; the base plate 1 is provided with a motor 503 for driving the gear and rack mechanism 502; the motor 503 is used to drive the first electric push rod 601 to push 10 times, and then drive the multi-compartment seed box 3 to move forward one storage compartment position through the double slide rail 501 and the gear and rack mechanism 502.

[0025] Specifically, the output shaft of motor 503 can drive the seed box to move laterally by a maximum of 300mm through the gear and rack mechanism 502, and the single-row switching distance is 100mm, so as to realize the switching of 4 rows of seed boxes or the switching of varieties.

[0026] In one embodiment, the seeding assembly 9 includes a seed box 901, a seed guide tube 902, a seed distributor 903, and a fan 904. The seed box 901, located at the output end of the slide 603, is embedded in the base plate 1. The seed box 901 is funnel-shaped. The box opener 7 is horizontally installed at the top opening of the seed box 901. The seed guide tube 902 is provided at the bottom output end of the seed box 901. The seed distributor 903 is provided at the output end of the seed guide tube 902. The fan 904 is provided below the bottom. The output end of the fan 904 is connected to the seed guide tube 902. The fan 904 is used to transport rapeseed seeds to the seed distributor 903 by blowing air. The seed distributor 903 is used to evenly distribute rapeseed seeds to multiple seed metering devices of the seeder.

[0027] Specifically, the bottom of the seed box 901 is connected to a three-way connector; the fan 904 is connected to the seed guide tube 902 through the three-way connector to provide airflow to blow the seeds to the seed divider 903; the seed divider 903 is fixed by the seed divider 903 support and has a multi-channel diversion structure inside to achieve uniform distribution of seeds for subsequent breeding and sowing operations.

[0028] In one embodiment, the upper part of the box opener 7 is a wedge plate, which is used to cut open the seed box 4. Support rods are horizontally arranged on the left and right sides of the wedge plate for support.

[0029] The method of using this invention is as follows: When in use, firstly, the seed boxes 4 filled with rapeseed seeds are placed in multiple storage compartments in a row, with 10 boxes stacked in each storage compartment; then, the device is activated, and the pusher of the first electric push rod 601 pushes the bottom seed box 4 of the frontmost storage compartment to the slide rail 603. After the first electric push rod 601 is reset, the second electric push rod 602 pushes the seed box 4 along the slide rail 603 to the position of the box opener 7 through the pusher.

[0030] When seed box 4 reaches seed box opener 7, the wedge-shaped structure of seed box opener 7 inserts into the gap of seed box 4 and opens it, and the seeds fall into seed box 901. The second electric push rod 602 continues to push, pushing the empty seed box 4 into recycling box 8. After the second electric push rod 602 resets, the first electric push rod 601 pushes the next seed box 4 to slide 603. The seeds in seed box 901 are blown to seed distributor 903 by airflow generated by fan 904 through seed guide tube 902. Seed distributor 903 evenly distributes the seeds to multiple seed metering devices, completing the sowing operation.

[0031] After the first electric push rod 601 pushes 10 times, the motor 503 starts, driving the multi-compartment seed box 3 to move laterally by 100mm via a rack and pinion mechanism. This moves the outlet of the next storage compartment to the push position, continuing the seed supply process. This cycle repeats until all seed boxes 4 have been used.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
