Description

Technical Field

[0001] The utility model relates to the technical field of seed metering devices, in particular to a brush for a finger-type seed metering device. Background Art

[0002] A seed metering device is a mechanical device for automatic sowing. While the seeding machine is moving, seeds are discharged from the discharge port and then automatically buried by filling soil, so as to achieve automatic sowing. Compared with traditional manual sowing, it has higher efficiency and better sowing effect, so it is widely promoted.

[0003] In the existing finger-type seed metering device, multiple seeds often hang on the edge of the finger clip during the seed metering process. When the finger clip moves to the seed metering port, multiple seeds fall into the seed metering port together, so as to achieve the situation of discharging multiple seeds at one time. Such seed metering not only wastes seeds, but also it is difficult for multiple seeds to survive in one seed pit. In order to facilitate the finger-type seed metering device to discharge only one seed each time, we propose a brush for a finger-type seed metering device. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the defects existing in the prior art, and a brush for a finger-type seed metering device is proposed.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is: a brush for a finger-type seed metering device, including a main body of the finger-type seed metering device, a seed metering port is opened on the rear end surface of the main body of the finger-type seed metering device, and further includes:

[0006] A T-shaped outer shell, a jack is opened on the circumferential surface of the main body of the finger-type seed metering device, the T-shaped outer shell is inserted into the jack, and the T-shaped outer shell is detachably connected to the main body of the finger-type seed metering device by screws;

[0007] A T-shaped slider, the T-shaped slider is slidably connected back and forth in the T-shaped outer shell, and a brush hair is fixedly connected to the lower end surface of the T-shaped slider;

[0008] A rotating column, rotating grooves are opened on the front and rear inner walls of the T-shaped outer shell, the rotating column is rotatably connected in the two rotating grooves, a circular hole communicating with the rear rotating groove is opened on the rear end surface of the main body of the finger-type seed metering device, and a connecting column rotatable in the circular hole is fixedly connected to the rear end surface of the rotating column;

[0009] A U-shaped block, the U-shaped block is fixedly connected to the middle part of the lower inner wall of the T-shaped slider;

[0010] A spiral plate, the spiral plate is fixedly connected to the circumferential surface of the rotating column, and the spiral plate slides in the U-shaped block to drive the T-shaped slider to move back and forth.

[0011] Preferably, a circular plate is fixedly connected to the rear end surface of the connecting column, and a slotted hole is opened on the rear end surface of the circular plate.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] In this solution, before the finger clips of the finger clip seed metering device hold the seeds and rotate to the seed metering port in the main body of the finger clip seed metering device, the brush hairs will brush across the surface of the finger clips, thereby brushing off the seeds on the finger clips except for the held ones. Furthermore, it is beneficial to avoid multiple seeds passing through the seed metering port and falling into the seed pits simultaneously. Finally, one seed per pit is achieved during the seed metering process, which is beneficial to avoid wasting seeds and facilitate improving the survival rate of the seeds.

[0023] The following description is used to disclose the utility model so that those skilled in the art can implement the utility model. The preferred embodiments described below are only examples, and those skilled in the art can think of other obvious variations.

[0024] As Figures 1 - 8 shown in the finger clip seed metering device brush, it includes the main body 1 of the finger clip seed metering device. A seed metering port 2 is drilled on the rear end face of the main body 1 of the finger clip seed metering device. It further includes:

[0025] The T-shaped housing 3 has insertion holes 4 drilled on the circumferential surface of the finger clip seed metering device body 1. The T-shaped housing 3 is inserted into the insertion holes 4, and the T-shaped housing 3 is detachably connected to the finger clip seed metering device body 1 by screws;

[0026] The T-shaped slider 5 is slidably connected to the inside of the T-shaped housing 3 in the front and rear directions. A brush 6 is fixedly connected to the lower end surface of the T-shaped slider 5;

[0027] The rotating column 8. Rotating grooves 13 are drilled on the front and rear inner walls of the T-shaped housing 3. The rotating column 8 is rotatably connected to the two rotating grooves 13. A circular hole 12 communicating with the rear rotating groove 13 is drilled on the rear end surface of the finger clip seed metering device body 1. A connecting column 10 that rotates in the circular hole 12 is fixedly connected to the rear end surface of the rotating column 8;

[0028] The U-shaped block 7 is fixedly connected to the middle of the lower inner wall of the T-shaped slider 5;

[0029] The spiral plate 9 is fixedly connected to the circumferential surface of the rotating column 8. The spiral plate 9 slides in the U-shaped block 7 to drive the T-shaped slider 5 to move back and forth.

[0030] During operation, when the finger clips of the finger clip seed metering device hold the seeds and rotate to the front of the seed metering port 2 in the finger clip seed metering device body 1, the brush 6 will brush across the surface of the finger clips, thereby brushing off the seeds on the finger clips except for the clamped ones. Furthermore, it is beneficial to avoid multiple seeds passing through the seed metering port 2 and falling into the seed pits at the same time. Finally, one seed per pit is achieved during the seed metering process, which is beneficial to avoid wasting seeds and facilitate improving the survival rate of seeds;

[0031] In this solution, by rotating the rotating column 8 to drive the spiral plate 9 to rotate, the spiral plate 9 slides and rotates in the U-shaped block 7 to drive the U-shaped block 7 to move back and forth, thereby facilitating the adjustment of the front and rear positions of the T-shaped slider 5. Furthermore, it is convenient to adjust the front and rear positions of the brush 6, thereby facilitating the adjustment of the distance between the brush 6 and the finger clips, and further facilitating the adjustment of the intensity of the brush 6 brushing the finger clips.

[0032] Specifically, a circular plate 11 is fixedly connected to the rear end surface of the connecting column 10, and a slotted hole is drilled on the rear end surface of the circular plate 11.

[0033] During operation, when it is necessary to rotate the rotating column 8, insert a flat-blade screwdriver into the slotted hole and rotate it, thereby driving the circular plate 11 to rotate, and further driving the rotating column 8 to rotate to achieve the adjustment of the position of the brush 6, which is very convenient and fast.

[0034] The working principle of the present utility model:

[0035] By rotating the rotating column 8 to drive the spiral plate 9 to rotate, the spiral plate 9 slides and rotates in the U-shaped block 7 to drive the U-shaped block 7 to move back and forth, thereby facilitating the adjustment of the front and rear positions of the T-shaped slider 5. Furthermore, it is convenient to adjust the front and rear positions of the brush 6, thereby facilitating the adjustment of the distance between the brush 6 and the finger clips, and further facilitating the adjustment of the intensity of the brush 6 brushing the finger clips.
