Description

Technical Field

[0001] This utility model relates to the technical field of land trenching, and more specifically, it relates to a trenching and soil delivery device for a mulching seeder. Background Technology

[0002] Full-film seeders are a very common type of equipment in modern agriculture. Full-film seeding technology has been widely promoted and applied due to its characteristics such as rainwater collection, moisture retention, drought resistance, temperature increase, and increased grain yield.

[0003] However, in actual use, the furrowing and soil conveying device of the full-film seeder has the following problems: First, when working in areas with many or large stones, because the chain is located in the middle of the soil removal device, stones can easily get stuck in the chain of the furrowing and soil conveying device, which can easily damage the chain in severe cases; Second, medium-sized stones that can pass through the furrowing and soil conveying device will first fall into the furrow outlet to press the soil in the furrow during the soil removal process, and then fall onto the mulch film in the furrow. When the roller seeder is sowing, the seed nozzle will hit the stone and bounce up, resulting in a large number of missing seedlings and reduced yield; Third, because the chain operates in the soil when furrowing, it cannot be lubricated and is in a dry grinding state, so the chain wears out too quickly and has a short service life, which will also affect the sowing operation. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a trenching and soil conveying device for a mulching seeder. By increasing the distance between the two chains, large stones can pass smoothly between the two chains, preventing stones from getting stuck between the chains and causing damage to the equipment.

[0010] The chain consists of two support wheels and two sprockets, each corresponding to a set of support wheels and sprockets, with a chain arranged in a closed loop around the corresponding set of support wheels and sprockets.

[0011] A soil-feeding bucket is set between two chains, with several soil-feeding buckets rotating with the two chains;

[0012] And a soil feeding trough, which is located below and along the arrangement direction of the driven shaft and the main drive shaft. As the soil feeding bucket moves with the chain, it drives the soil and stones to move upward along the inclined direction of the soil feeding trough.

[0031] To enable those skilled in the art to better understand the technical solution of this utility model, the technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Based on the embodiments in this application, other similar embodiments obtained by those skilled in the art without creative effort should all fall within the scope of protection of this application. Furthermore, directional terms mentioned in the following embodiments, such as "up," "down," "left," and "right," are only for reference to the directions in the accompanying drawings; therefore, the directional terms used are for illustrative purposes and not for limiting the invention.

[0032] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.

[0033] Example: A furrowing and soil-feeding mechanism for a mulching seeder, see attached document. Figure 1 -Appendix Figure 6The system includes a frame 1, a main drive shaft 2, sprockets 3, a driven shaft 5, support wheels 4, a chain 6, a soil hopper 7, and a soil trough 8. The main drive shaft 2 is rotatably connected to the frame 1. A gearbox is mounted on the frame 1 and is connected to the main drive shaft 2. The gearbox is also connected to a diesel engine or other power machinery to provide power for the rotation of the main drive shaft 2. Two sprockets 3 are large-pitch sprockets, located at both ends of the main drive shaft 2. The driven shaft 5 is rotatably connected to the frame 1. The main drive shaft 2 and the driven shaft 5 are arranged at an angle, with the direction of arrangement closer to the driven shaft 5. The driven shaft 5 is positioned at the front end of the frame 1 in the forward direction, tilted downwards. Two support wheels 4 are provided, each located at one end of the driven shaft 5. The two support wheels 4 and two sprockets 3 correspond one-to-one, and a chain 6 arranged in a closed loop surrounds the corresponding set of support wheels 4 and sprockets 3. Several soil-feeding buckets 7 are provided between the two chains 6, which rotate with the two chains 6. The soil-feeding trough 8 is located below the arrangement direction of the driven shaft 5 and the main drive shaft 2 and is arranged along the arrangement direction of the driven shaft 5 and the main drive shaft 2. As the soil-feeding buckets 7 move with the chain 6, they drive the soil and stones to move upwards along the tilt direction of the soil-feeding trough 8.

[0034] The frame 1 moves forward on the ground. During this movement, the main drive shaft 2 drives the two chains 6 to rotate. As the chains 6 rotate, they drive the soil hopper 7 to scoop up soil and stones and push them upwards from the soil trough 8, i.e., backwards in an inclined direction. By setting the two sprockets 3 to large pitch sprockets, the distance between the two sprockets 3 is increased, which in turn increases the distance between the two chains 6. This allows large stones to pass smoothly between the two chains 6, preventing stones from getting stuck.

[0035] Specifically, chain 6 includes inner chain plates 6-1 and outer chain plates 6-3, which are arranged alternately along the wrapping direction of chain 6; the connection points of inner chain plates 6-1 and outer chain plates 6-3 are connected together by a long chain shaft 6-4. The connection points of the outer chain plates 6-3 and inner chain plates 6-1 of the two chains 6 correspond one-to-one, and the corresponding connection points of the outer chain plates 6-3 and inner chain plates 6-1 are connected together by a long chain shaft 6-4 passing through the two chains 6. A long chain tube 6-2 is sleeved on the long chain shaft 6-4, located between the two inner chain plates 6-1 of the two chains 6, and the two ends of the long chain tube 6-2 are fixedly connected to the two inner chain plates 6-1.

[0036] By using the long chain tube 6-2 and the long chain shaft 6-4, the friction area is increased without lubrication, thereby extending the life of the chain 6 and reducing the cost of use.

[0037] Specifically, the two ends of the soil-feeding bucket 7 are also fixedly connected to the corresponding two inner chain plates 6-1.

[0038] Specifically, the distance between the soil feeding hopper 7 and the soil feeding trough 8 gradually increases along the upward slope of the soil feeding trough 8. This ensures that as long as the stones can enter the soil feeding hopper 7, they can be smoothly fed out without getting stuck, which would prevent the chain 6 from moving properly.

[0039] Specifically, a soil outlet 9 is provided near the inclined top of the soil delivery trough 8, penetrating the soil delivery trough 8; a strip grate 11 is provided at the soil outlet 9 to prevent stones from passing through the soil outlet 9. The inclined top of the soil delivery trough 8 is provided as a soil pressing outlet 10.

[0040] The arrangement of the soil outlet 9 and the strip grate 11 allows fine soil to fall from the soil outlet 9 to press the film in the furrow, while large stones, stubble, and large soil clods fall from the soil pressing port 10 behind the soil delivery trough 8 to press the film edge, thus preventing them from affecting the sowing of the seeder.

[0041] Specifically, a plate 12 is provided on the side of the soil delivery trough 8 away from the chain 6, which can slide along the length of the soil delivery trough 8 to adjust the size of the soil outlet 9. By setting the plate 12, the amount of soil discharged from the soil outlet 9 can be controlled, thereby adjusting the amount of soil compacted in the furrow.

[0042] Specifically, the sprocket 3 is configured as a double-wheel structure, and the support wheel 4 is configured as a double-wheel structure.

[0043] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
