Description

Technical Field

[0001] This utility model relates to the field of peanut seed metering machine technology, and in particular to an adjustable peanut seed metering machine. Background Technology

[0002] The peanut seed metering machine is a core component of agricultural machinery specifically designed for peanut planting. It employs a dual-chamber vibration or pneumatic suction seed metering structure to ensure precise single-seed or double-seed planting of shelled peanuts (15-25mm in diameter). Its core modules include an adjustable seed trough (adapting to different pod sizes), a breakage-resistant seed guide tube (lined with rubber or polyurethane), and a photoelectric monitoring system that provides real-time feedback on missed and replanting rates (accuracy ≥98%). Some high-end models integrate a hydraulic contour-following mechanism, automatically adjusting the planting depth (20-50mm) according to terrain undulations. Combined with BeiDou navigation, it achieves precise operation with a row spacing error of ±2cm, achieving a planting efficiency of 8-12 mu / hour, 15 times higher than manual planting, while reducing seed damage rate to below 3%.

[0003] The seed clamps of a peanut seed metering machine hold and hold the peanuts, thus enabling their directional movement. However, the size of peanut kernels varies from year to year, so the size of the seed clamps inside the seed metering machine needs to be changed according to actual needs. Currently, the seed clamps inside the peanut seed metering machine are fixed to the seed metering wheel with screws, so changing the seed clamps requires removing and unscrewing each one, which is very troublesome. In order to facilitate the quick change of seed clamp size, we propose an adjustable peanut seed metering machine. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an adjustable peanut seeding machine.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an adjustable peanut seed metering machine, comprising two seed metering machine housings, the two seed metering machine housings being fixedly connected and fastened by screws, and further comprising:

[0006] A seed metering wheel, which is rotatably connected between two seed metering machine housings;

[0007] Multiple seed clips, each with peanut slots of different sizes carved at both ends to hold peanuts of different sizes, are staggered on the front and rear sides of the seed metering wheel. Each seed clip has a connecting post fixedly connected to one end face near the seed metering wheel, and a square limiting plate is fixedly connected to the circumferential surface of each connecting post.

[0008] Multiple round holes are drilled through the front end face of the seed metering disc. Multiple connecting posts are inserted into the multiple round holes. Multiple square limiting grooves are drilled on both the front and rear end faces of the seed metering disc. The multiple square limiting grooves are connected to the multiple round holes. Multiple square limiting plates are respectively engaged in the multiple square limiting grooves to restrict the rotation of the seed clip.

[0009] Multiple circular limiting grooves are provided. Multiple circular limiting grooves are carved on both the front and rear end faces of the seeding wheel. The multiple circular limiting grooves are respectively connected to multiple circular holes. Multiple connecting columns are threaded with locking screws, and the locking screws are located inside the circular limiting grooves. Springs are sleeved on the circumferential surface of multiple connecting columns, and the springs are located between the locking screws and the inner wall of the circular limiting grooves.

[0010] Preferably, a rack and pinion sealing plate is slidably connected between the two seed metering machine housings, and a first gear handle is rotatably connected through the front seed metering machine housing. The first gear handle is engaged with the rack and pinion sealing plate to control the opening and closing of the seed metering machine inlet.

[0011] Preferably, a baffle is slidably connected between the two seed metering machine housings, and a toothed plate is fixedly connected to the upper end face of the baffle. A second gear handle is rotatably connected through the front seed metering machine housing, and the second gear handle is engaged with the toothed plate to control the seed flow rate of the seed metering machine.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] In this solution, since the seed metering disc rotates in one direction during operation and the opening sizes of the two peanut slots are different, the orientation of the peanut slots can be adjusted by rotating the disc to allow the seed clips to hold peanuts of different sizes. This allows for the adjustment of the seed clips to hold peanuts of different sizes without disassembling or replacing them, making the operation very simple and quick.

[0014] In this solution, when it is necessary to adjust the peanut seed flow rate, the second gear handle is rotated. The rotation of the second gear handle drives the gear on the second gear handle to rotate, and the rotation of the gear on the second gear handle drives the toothed plate to move linearly, thereby adjusting the distance between the baffle and the inner wall of the seed metering machine. This makes it easier to control the speed of seed falling, thus helping to avoid the phenomenon of seeds getting stuck due to peanuts falling too fast, and facilitating the normal rotation of the seed metering disc for seed metering.

Detailed Implementation

[0020] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0021] like Figures 1-4 The adjustable peanut seed metering machine shown includes two seed metering machine housings 1, which are fixedly connected and fastened together by screws, and also includes:

[0022] Seeding wheel 7, which is rotatably connected between two seed metering machine housings 1;

[0023] Multiple seed clips 8, each seed clip 8 has peanut slots 16 of different sizes carved at both ends to hold peanuts of different sizes. The multiple seed clips 8 are staggered on the front and rear sides of the seed metering wheel 7. Each seed clip 8 has a connecting post 15 fixedly connected to the end face of the seed metering wheel 7. Each connecting post 15 has a square limiting plate 12 fixedly connected to the circumferential surface of the circumference.

[0024] Multiple round holes 10 are drilled through the front end face of the seed metering disc 7. Multiple connecting posts 15 are inserted into the multiple round holes 10 respectively. Multiple square limiting grooves 11 are drilled on both the front and rear end faces of the seed metering disc 7. The multiple square limiting grooves 11 are connected to the multiple round holes 10 respectively. Multiple square limiting plates 12 are respectively engaged in the multiple square limiting grooves 11 to restrict the rotation of the seed clamp 8.

[0025] Multiple circular limiting grooves 9 are carved on both the front and rear end faces of the seeding wheel 7. The multiple circular limiting grooves 9 are connected to multiple circular holes 10 respectively. Multiple connecting posts 15 are threadedly connected with locking screws 13, and the locking screws 13 are located inside the circular limiting grooves 9. Springs 14 are sleeved on the circumferential surface of multiple connecting posts 15, and the springs 14 are located between the locking screws 13 and the inner wall of the circular limiting grooves 9.

[0026] When it is necessary to change the seed clamp during operation, open the two seed metering machine housings 1 and take out the seed metering disc 7. Hold the seed clamp 8 and pull it away from the side of the seed clamp 8. The spring 14, which is pressed between the locking screw 13 and the inner wall of the circular limit groove 9, is compressed. The square limit plate 12 disengages from the square limit groove 11. After rotating the seed clamp 8 180 degrees, release the seed clamp 8. Under the elastic reset of the spring 14, pull the rotated square limit plate 12 back into the square limit groove 11, thereby realizing the rotation and reversal of the seed clamp 8. Since the seed metering disc rotates in one direction during operation, and the opening size of the two peanut slots 16 is different, the orientation of the peanut slots 16 can be adjusted by rotating to adjust the size of the peanuts that the seed clamp 8 can hold. This allows the seed clamp 8 to hold different sizes of peanuts without disassembling and replacing the seed clamp 8. The operation is very simple and quick.

[0027] In practical use, the two peanut slots 16 of the seed clip 8 can be distinguished by different colors, so that the orientation of the peanut slots 16 can be more intuitively judged by the naked eye when adjusting.

[0028] Specifically, a rack and pinion sealing plate 2 is slidably connected between the two seed metering machine housings 1, and a first gear handle 3 is rotatably connected through the front seed metering machine housing 1. The first gear handle 3 is engaged with the rack and pinion sealing plate 2 to control the opening and closing of the seed metering machine inlet.

[0029] When the seed metering machine is in operation, the first gear handle 3 is rotated. The rotation of the first gear handle 3 drives the gear on the first gear handle 3 to rotate. The rotation of the gear on the first gear handle 3 drives the rack sealing plate 2 to move linearly, thereby adjusting the size of the seed inlet and facilitating the entry of peanuts into the two seed metering machine housings 1. When the seed metering machine is not in use, the rack sealing plate 2 is rotated to close, thereby preventing dust and impurities from entering the two seed metering machine housings 1 and affecting the subsequent operation of the seed metering disc 7, and preventing the seed metering disc 7 from getting stuck.

[0030] Specifically, a baffle 5 is slidably connected between the two seed metering machine housings 1, and a toothed plate 6 is fixedly connected to the upper end face of the baffle 5. A second gear handle 4 is rotatably connected through the front seed metering machine housing 1. The second gear handle 4 is engaged with the toothed plate 6 to control the seed flow rate of the seed metering machine.

[0031] When it is necessary to adjust the peanut seed flow rate during operation, rotate the second gear handle 4. The rotation of the second gear handle 4 drives the gear on the second gear handle 4 to rotate, and the rotation of the gear on the second gear handle 4 drives the toothed plate 6 to move linearly, thereby adjusting the distance between the baffle 5 and the inner wall of the seed metering machine housing 1. This facilitates the control of the seed falling speed, which helps to avoid the phenomenon of seeds getting stuck due to peanuts falling too fast, and also facilitates the normal rotation of the seed metering wheel 7 for seed metering.

[0032] Working principle of this utility model:

[0033] When it is necessary to replace the seed clamp, open the two seed metering machine housings 1 and take out the seed metering disc 7. Hold the seed clamp 8 and pull it away from the side of the seed clamp 8. The spring 14, which is pressed between the locking screw 13 and the inner wall of the circular limiting groove 9, is compressed. The square limiting plate 12 is disengaged from the square limiting groove 11. After rotating the seed clamp 8 180 degrees, release the seed clamp 8. Under the elastic reset of the spring 14, pull the rotated square limiting plate 12 back into the square limiting groove 11, thereby realizing the rotation and reversal of the seed clamp 8.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this utility model.
