Description

Technical Field

[0001] This utility model relates to an automatic seed-laying mechanism for a pre-cut sugarcane planter using a brush. Background Technology

[0002] Currently, the automatic seeding mechanism of sugarcane planting machines in China mainly involves adding a conveyor to the rear of the feed box for feeding. The conveyor is equipped with a chain, and the sugarcane seed trough is fixed on the chain. This type of sugarcane seed trough is prone to damaging the sugarcane seed when conveying the sugarcane seed upward.

[0003] In China, semi-automatic sugarcane planting machines primarily use seed-laying mechanisms, which are divided into whole-stalk and pre-cut seed-laying synchronized mechanisms. Whole-stalk sugarcane planters are powered by tractors and include a power cutting box. Next to the seed-laying port of the cutting box, there is a work chair for workers to plant sugarcane, a seed box, and a fertilizer applicator. Pre-cut seed-laying synchronized mechanisms are also powered by tractors and have a work chair for workers to plant sugarcane, a seed box, and a fertilizer applicator next to the seed-laying port; the operation mode is still manual feeding. These two types of sugarcane planter synchronized devices have the following problems in use: Pre-cut seed-laying synchronized devices require one person to drive the machine, and two people to handle seed placement and fertilization, failing to completely free up labor and achieve full automation of sugarcane planting; because seed placement is manual, the coordination between the vehicle speed and the manual seed placement speed must be accurate to ensure even seeding, which creates coordination difficulties, especially when workers are fatigued, leading to missed planting and seed clogging, resulting in low planting efficiency. Utility model content:

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide an automatic seed-laying mechanism for a pre-cut sugarcane planter.

[0005] An automatic seeding mechanism for a pre-cut sugarcane planter includes a transmission mechanism, an execution mechanism, and an auxiliary feeding mechanism. The execution mechanism is mounted on a feeding box and includes a feeding roller, an auxiliary roller, an upper roller, a feeding baffle, and a guide plate. The upper roller is located above the feeding roller, and the auxiliary roller is located to the side of the feeding roller. The outer wall of the feeding roller is provided with a plurality of first teeth at intervals, and the outer wall of the upper roller is provided with a plurality of second teeth at intervals. The second teeth are brushes, and there is a predetermined gap between the upper roller and the feeding roller.

[0006] The guide plate is placed obliquely between the hopper and the dropping box. One end of the guide plate is located in the hopper, and the other end leads to the material loading area between the feeding roller, the auxiliary roller, and the upper roller.

[0007] The transmission mechanism is used to provide power to the actuator. The auxiliary feeding mechanism includes a hopper, which is located above the discharge box and its internal space is connected to the discharge box. The discharge baffle is placed obliquely on the discharge box, with one end leading to the feeding roller and the other end leading to the ground.

[0008] Furthermore, the transmission mechanism includes a first transmission sprocket, a second transmission sprocket, a third transmission sprocket, a fourth transmission sprocket, a first transmission gear, and a second transmission gear. The first transmission sprocket is mounted on the material drop box and is connected to the second transmission sprocket via a chain. The second transmission sprocket and the first transmission gear are mounted on an auxiliary roller. The third transmission sprocket and the second transmission gear are mounted on a feeding roller. The first transmission gear meshes with the second transmission gear. The fourth transmission sprocket is mounted on an upper roller and is connected to the third transmission sprocket via a chain.

[0009] Furthermore, the lower section of the silo has an inverted conical structure.

[0010] Furthermore, the hopper has two horizontally placed partitions inside, with an adjustable gap between them.

[0011] Furthermore, the surface of the partition plate is provided with multiple through holes.

[0012] Furthermore, the first tooth is a U-shaped bent plate.

[0013] Furthermore, the second tooth is fixed to the outer wall of the upper roller by bolts.

[0014] Beneficial effects: Compared with the prior art, the present invention has the following advantages;

[0015] The simple conical hopper structure facilitates continuous material feeding.

[0016] The three-roller mechanism, with the assistance of the auxiliary roller and the upper roller, and the power provided by the feeding roller, allows the sugarcane seed to fall continuously from the gap set by the feeding roller and the brush roller, thus achieving automatic feeding in the same direction. The setting of the sugarcane seed trough of the feeding roller and the left and right partitions of the material box achieves uniform feeding and can plant sugarcane seeds of different diameters and lengths, with a wide operating range.

[0017] With the feed hopper in front and the material drop area behind, the center of gravity is forward, making room for rotary tillage, ditching, and fertilization in front, and making it more reasonable.

[0018] The brush roller has a dense array of brushes that do not form cavities, preventing the sugarcane seeds from being pushed or stuck. The brushes also have good wear resistance. The brush roller replaces the baffle, creating a gap with the feeding roller to prevent damage to the sugarcane during seed distribution. Attached Figure Description

The outer side wall of the feeding roller 3 is provided with a plurality of first teeth at intervals, and the outer side wall of the upper roller 4 is provided with a plurality of second teeth 7 at intervals. The second teeth 7 are brushes.

[0027] The guide plate 16 is placed obliquely between the hopper and the dropping box. One end of the guide plate is located in the hopper, and the other end leads to the material loading area between the feeding roller, the auxiliary roller, and the upper roller.

[0028] The transmission mechanism is used to provide power to the actuator. The auxiliary feeding mechanism includes a hopper 1, which is located above the discharge box 2 and its internal space is connected to the discharge box 2. The discharge baffle 6 is placed obliquely on the discharge box, with one end leading to the feeding roller 3 and the other end leading to the ground.

[0029] In this example, the transmission mechanism includes a first transmission sprocket 9, a second transmission sprocket 10, a third transmission sprocket 11, a fourth transmission sprocket 12, a first transmission gear 13, and a second transmission gear 14. The first transmission sprocket 9 is mounted on the material drop box 2 and is connected to the second transmission sprocket 10 by a chain.

[0034] In this example, the second tooth 7 is fixed to the outer wall of the upper roller 4 by bolts 8.

[0035] Instructions for Use: Sugarcane planters are often used as agricultural implements and need to be attached to the back of a tractor. Therefore, the further forward the center of gravity, the better. The main power of the sugarcane planter generally comes from the ground wheel. The material drop area is at the rear, and the conical hopper is at the front. When moving forward, the ground wheel will rotate counterclockwise. The drive sprocket can act as the driving wheel and rotate counterclockwise, providing a driving force to the sugarcane seed at the bottom of the conical hopper. The material drop roller, through the combination of the material drop roller gear, chain, auxiliary roller gear, drive sprocket chain, and auxiliary roller sprocket, achieves clockwise rotation. At the same time, the brush roller rotates clockwise through the chain and the material drop roller. The drive sprocket is mounted on the material drop box. The auxiliary roller is equipped with both the auxiliary roller sprocket and the auxiliary roller gear. Power is transmitted from the ground wheel to the drive sprocket and then through the chain to the auxiliary roller sprocket, driving the auxiliary roller to move counterclockwise. As the auxiliary roller sprocket rotates counterclockwise, the auxiliary roller gear on the auxiliary roller meshes with the feeding roller gear, thus enabling the feeding roller to rotate clockwise. The upper roller sprocket is mounted on the brush roller and connected to the feeding roller via a chain, moving clockwise. Sugarcane seeds continuously fall from the gaps between the brush roller and the feeding roller. A discharge baffle is mounted on the discharge box. When the sugarcane seeds are scooped into the sugarcane seed trough on the feeding roller, the auxiliary roller clears and sorts the subsequent sugarcane seeds to prevent them from being placed at an angle. When the sugarcane seeds rotate with the feeding roller to the bottom of the brush roller, the brush roller removes excess sugarcane seeds. The sugarcane seeds then rotate 90° clockwise before falling onto the discharge baffle, and then fall evenly and smoothly, thus automating the sugarcane seed distribution.

[0036] The partition is installed on the conical hopper. For sugarcane of different lengths, the partition can be adjusted to the appropriate position to achieve the adjustment of the entire system.

[0037] To ensure a smooth and continuous descent of the sugarcane seeds, they can be pre-positioned so that the seeds are aligned with the seed trough of the feeding roller.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
