Description

Technical Field

[0001] The present invention relates to the technical field of agricultural seeders, and in particular to a high-efficiency seeding device capable of array-type precision seeding. Background Art

[0002] A seeder is an important agricultural equipment that can discharge seeds intermittently and quantitatively. Existing seeders generally use seed wheels and other forms to discharge seeds, and their seeding accuracy is not high enough. For occasions where high seeding accuracy is required, traditional seeders are difficult to meet the requirements. For example, in the case of sowing and raising seedlings in seedling trays, a precise number of seeds need to be sown in each seedling hole in the seedling tray. In this case, traditional seeders are difficult to meet the requirements.

[0003] The applicant's prior patent applications, such as CN207201279U and CN112449810A, disclose a rotary precision seeding device. These patents provide a seed box with shaped holes and upper and lower blocking mechanisms on the upper and lower sides of the bottom plate, respectively, to achieve seed filling and seed discharge. However, during use, the upper blocking mechanism in the CN207201279U solution can easily get stuck, causing the door to fail to close or cutting off the seeds. Although the CN112449810A solution provides a separate blocking bar for each shaped hole, preventing the problem of one shaped hole getting stuck and affecting the sealing of all shaped holes, the problem of several blocking bars getting stuck still exists.

[0004] Another type of prior patent application of the applicant, CN111480428A, CN111492754A, etc., discloses another seed filling mechanism of a seeder. This scheme sets a power mechanism on both sides of the seed filling screen so that the two ends of the seed filling screen can be lifted by the power mechanism in turn and the entire screen can vibrate. In this way, the seed population can migrate back and forth between the two ends of the seed filling screen to perform the seed filling operation. In this way, since the seed population migrates between the two ends of the seed filling screen to fill the shaped holes with seeds, the migration distance of the seed population is long, and migrating from one end to the other end can only complete the seed filling of all the shaped holes once, resulting in low seed filling efficiency. In addition, the reseeding structure in this scheme is relatively complex, which will increase the volume of the mechanism. Summary of the Invention

[0005] Purpose of the invention: In order to overcome the deficiencies in the prior art, the present invention provides an efficient seeding device capable of array-type precision sowing and seeding with high seed filling efficiency and no jamming problem.

[0006] Technical Solution: To achieve the above-mentioned purpose, the present invention provides an efficient seeding device capable of array-type precision sowing and seeding, which includes a seed box capable of reciprocating swinging motion, wherein a plurality of shaped holes arranged in an array are formed on the bottom plate of the seed box; a lower release mechanism is provided on the lower side of the bottom plate, which can block the bottom of the shaped holes to prevent seeds in the shaped holes from falling out, and can also release the blockage to allow the seeds in the shaped holes to fall out;

[0007] An auxiliary plate is mounted on the upper side of the bottom plate, abutting against its upper end surface, and a plurality of through slots arranged in an array are formed on the auxiliary plate; the first end of the bottom of each through slot has at least one of the shaped holes, and the second end opposite to the first end is in a closed state; when the seed box swings back and forth, the first end can be switched back and forth between a high position and a low position; and when the seeding task is performed, each through slot is always not filled with seeds;

[0008] An upper release mechanism is provided on the upper side of the auxiliary plate, capable of switching the upper end of the through slot between a closed state and an open state. Seeds are contained in the space above the upper release mechanism within the seed box. When the upper end of the through slot is open, the seeds in the space above the release mechanism can enter the through slot for replanting.

[0009] During seeding, the seed box swings back and forth, moving along the axis of rotation. Simultaneously, the box performs a reciprocating translational motion parallel to the axis of rotation. This translational motion allows the seeds within each slot to fully move toward the lower end of the slot. When the first end of the slot is at a low position, all seeds within the slot converge toward the first end, and the reciprocating translational motion of the seed box ensures that seeds enter the shaped holes. When the second end of the slot is at a low position, all seeds within the slot converge toward the second end, and the reciprocating translational motion of the seed box fully clears the seeds from the first end, leaving only the seeds within the shaped holes at the first end. When the second end of the slot is at a low position, the lower release mechanism opens, allowing the seeds within the shaped holes to fall out.

[0010] With the above structure, seed slots are provided for the shaped holes, and the slots are always kept unfilled. All slots divide all the shaped holes into multiple groups. With the reciprocating swing and translational motion of the seed box, each slot can be independently filled and cleared of seeds. Clearing the seeds is to clear the seeds around the shaped holes. Because the movement range of the seeds in each slot is small, and the filling and clearing processes in all slots are carried out synchronously, the filling efficiency can be greatly improved and the filling accuracy is high. Because the seed cleaning does not use a door-type filling mechanism, there is no problem of the filling mechanism getting stuck.

[0011] Furthermore, the lower release mechanism includes a lower translation plate, which can be driven by a first driving device to slide relative to the bottom plate; a release hole is formed on the lower translation plate; the first driving device can make the shaped hole and the release hole staggered or connected, when the shaped hole and the release hole are staggered, the seeds in the shaped hole will not leak out; when the shaped hole and the release hole are connected, the seeds in the shaped hole will fall out through the release hole.

[0012] Furthermore, the upper release mechanism includes an upper translation plate that can be driven by a second drive device to slide relative to the auxiliary plate. Above the upper translation plate, a seeding hole corresponding to the through-slot is formed on the upper translation plate. The second drive device can cause the through-slot to be offset from or connected to the seeding hole. When the through-slot is offset from the seeding hole, the upper end of the through-slot is closed, and seeds are contained in the space above the upper translation plate. When the through-slot is connected to the seeding hole, seeds in the space above the upper translation plate can enter the through-slot.

[0013] Furthermore, the reseeding hole is shorter than the through slot; when the reseeding hole is connected to the through slot, the second end of the through slot is at a lower position, and when viewed perpendicular to the upper translation plate, the reseeding hole is located at the second end of the through slot. In this way, each time the through slot is reseeded, the slot will not be completely filled, leaving space for clearing the seeds.

[0014] Furthermore, the opening and closing frequency of the lower release mechanism is at least one order of magnitude higher than that of the upper release mechanism. If the lower release mechanism is opened and closed 20 times, the upper release mechanism is opened and closed once, so that the through slot can be replenished with an appropriate amount of seeds at regular intervals.

[0015] Beneficial effects: The efficient seeding device capable of array-type precision sowing and seeding of the present invention is provided with an auxiliary plate having a through slot, and the mold hole is located at one end of the through slot, so that when the seed box swings back and forth, each through slot can perform independent seed filling and seed clearing operations, and the seeds in each through slot move within a limited range. The seed box can complete a seed filling and seed clearing operation once each reciprocating swing cycle, and the seed filling efficiency is high. In addition, since there is no need to close the door on the mold hole, the problem of mechanism jamming is avoided. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] The present invention will be further described below with reference to the accompanying drawings.

[0024] like Figure 1 The high-efficiency seeding device capable of array-type precision sowing and seeding shown includes a seed box 1 capable of reciprocating swinging motion, wherein a plurality of shaped holes 12 arranged in an array are formed on a bottom plate 11 of the seed box 1; a lower release mechanism 3 is provided on the lower side of the bottom plate 11, and the lower release mechanism 3 can block the bottom of the shaped holes 12 to prevent the seeds in the shaped holes 12 from falling out, and can also release the blockage to allow the seeds in the shaped holes 12 to fall out;

[0025] like Figure 2 As shown, an auxiliary plate 2 is mounted on the upper side of the bottom plate 11 and abuts against its upper end surface. A plurality of through slots 21 arranged in an array are formed on the auxiliary plate 2. The first end of the bottom of each through slot 21 has at least one of the shaped holes 12, and the second end opposite to the first end is in a closed state. When the seed box 1 swings back and forth, the first end can be switched back and forth between a high position and a low position. When the seeding task is performed, each through slot 21 is always not filled with seeds.

[0026] An upper release mechanism 4 is provided on the upper side of the auxiliary plate 2. This mechanism switches the upper end of the through slot 21 between a closed and an open state. Seeds are contained in the space above the upper release mechanism 4 within the seed box 1. When the upper end of the through slot 21 is open, the seeds in the space above the release mechanism 4 can enter the through slot 21 for replanting.

[0027] When performing seeding operation, the seed box 1 performs reciprocating swinging motion, and the swinging motion is performed along the rotation axis; at the same time, the seed box 1 performs reciprocating translation motion, and the translation direction is parallel to the axial direction of the rotation axis. The translation motion of the seed box 1 can fully move the seeds in each through groove 21, and the seeds can move to the lower end of the through groove 21. Figure 3 、 4As shown, when the first end of the through groove 21 is at a low position, all the seeds in the through groove 21 gather toward the first end of the through groove 21, and the reciprocating translation of the seed box 1 can ensure that the seeds enter the shaped hole 12; Figure 5 、 6 As shown, when the second end of the through slot 21 is in a low position, all seeds in the through slot 21 gather toward the second end of the through slot 21. The reciprocating translation of the seed box 1 can fully remove the seeds at the first end, leaving only the seeds in the shaped hole 12 at the first end. When the second end of the through slot 21 is in a low position, the lower release mechanism 3 opens, allowing the seeds in the shaped hole 12 to fall out.

[0028] With the above structure, since the through slots 21 for accommodating seeds are provided for the mold holes, and the through slots 21 are always kept in a state of not being filled with seeds, all the through slots 21 divide all the mold holes 12 into multiple groups. With the reciprocating swinging motion and translational motion of the seed box 1, each through slot 21 can be independently filled and cleared of seeds. Clearing seeds is to clear the seeds around the mold holes 12. Since the movement range of the seeds in each through slot 21 is small, and the filling and clearing processes in all through slots 21 are carried out synchronously, the filling efficiency can be greatly improved, and the filling accuracy is high. Since the seed cleaning does not use the upper closing door filling mechanism, there is no problem of the filling mechanism getting stuck.

[0029] Preferably, the lower release mechanism 3 includes a lower translation plate 31, which can be driven by a first driving device 32 to slide relative to the base plate 11; a release hole 311 is formed on the lower translation plate 31; the first driving device 32 can make the shaped hole 12 staggered or connected with the release hole 311. When the shaped hole 12 and the release hole 311 are staggered, the seeds in the shaped hole 12 will not leak out; when the shaped hole 12 and the release hole 311 are connected, the seeds in the shaped hole 12 will fall out through the release hole 311.

[0030] Preferably, the upper release mechanism 4 includes an upper translation plate 41 that can be driven by a second drive device 42 to slide relative to the auxiliary plate 2. Above the upper translation plate 41, a reseeding hole 411 corresponding to the through slot 21 is formed on the upper translation plate 41. The second drive device 42 can cause the through slot 21 to be offset from or connected to the reseeding hole 411. When the through slot 21 is offset from the reseeding hole 411, the upper end of the through slot 21 is closed, and seeds are contained in the space above the upper translation plate 41. When the through slot 21 is connected to the reseeding hole 411, seeds in the space above the upper translation plate 41 can enter the through slot 21.

[0031] Preferably, the reseeding hole 411 is shorter than the through slot 21; when the reseeding hole 411 is connected to the through slot 21, the second end of the through slot 21 is at a low position, and when viewed in a direction perpendicular to the upper translation plate 41, the reseeding hole 411 is located at the second end of the through slot 21. Figure 6 In this way, each time the through slot 21 is reseeded, the through slot 21 will not be filled up, and space can be left for clearing the seeds.

[0032] Preferably, the opening and closing frequency of the lower release mechanism 3 is at least one order of magnitude higher than that of the upper release mechanism 4. For example, if the lower release mechanism 3 is opened and closed 20 times (i.e., 20 seeding operations are completed), the upper release mechanism 4 is opened and closed once, so that the through slot 21 can be replenished with an appropriate amount of seeds at regular intervals.

[0033] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
