Description

Technical Field

[0001] The present application relates to the technical field of agricultural machinery, and in particular to a driven straw cleaning device with energy storage function for a no-till planter. Background Art

[0002] No-till seeding operation refers to the one-time integration of soil trenching, seed arrangement and soil backfilling without tilling the soil and retaining crop residue (straw) covering the surface. This operation mode aims to reduce the frequency of soil tillage and reduce operating costs, while enhancing the soil's water retention and conservation capacity, promoting the straw return mechanism, and thus improving the soil organic matter level, soil fertility, and optimizing the soil physical structure.

[0003] However, due to the large amount of straw and root-soil complex remaining on the field surface, if the straw is not broken enough during no-till seeding, it is easy to cause the furrow opener to become blocked, resulting in uneven furrowing operations, and ultimately affecting the seeding accuracy and subsequent crop growth.

[0004] As the key to the research of no-till seeding technology, the anti-blocking effect directly affects the seeding quality and production efficiency of the machine. Improving the anti-blocking performance, seeding quality and production efficiency of no-till seeders is of great research significance.

[0005] The anti-blocking and straw-clearing mechanisms currently used in no-till planters are mainly divided into two categories: passive and active. The passive mechanism relies on the weight of the machine itself and attempts to clean the sowing belt by cutting, poking, etc., but this method requires heavy tractor traction, which is easy to aggravate soil compaction, and the straw-clearing effect is limited, and the anti-blocking mechanism itself is also prone to blockage. An existing patent for a spring-tooth straw-clearing device for a no-till planter (CN 215991844 U) uses a disc knife and a straw-clearing spring tooth to cooperate with the ground to drive it to rotate along the ground to clean the straw during its operation. Although it has a strong anti-entanglement ability, the straw cleaning rate is low and the straw cleaning effect is poor.

[0006] The active anti-blocking mechanism is driven by an external power source to achieve the cutting and throwing of straw. Compared with the passive type, its anti-blocking effect is more significant, but it is accompanied by higher requirements for tractor power and increased soil disturbance. The existing patent is a combined stubble-breaking and straw-clearing anti-blocking device (CN 118176854A). Its operation process is coordinated by the stubble-breaking device and the rotary throwing device. The disc cuts the straw by rotating, and the rear driven rotary throwing device rotates the straw to the rear to achieve the functions of stubble-breaking and straw-clearing and inter-row straw recovery. The straw clearing rate is high, but the disturbance of the field soil is large and the operation power consumption is high. Utility Model Content

[0032] In response to the above problems, an embodiment of the present application provides a driven straw cleaning device with energy storage function for a no-till seeder. The straw cleaning mechanism rotates to drive the straw cleaning unit to clean the straw on the surface. It has strong side throwing and anti-entanglement capabilities, small soil disturbance, and good anti-blocking effect.

[0033] The technical solution of the embodiments of the present application is described in detail below with reference to the accompanying drawings.

[0034] See also Figure 1-2 The driven straw clearing device with energy storage function of the no-till planter includes a frame 1, a steering gear 2, an external rotating shaft 3, a bevel gear rotating shaft 4, a primary transmission chain mechanism 5, a secondary transmission chain mechanism 6, and a straw clearing mechanism 7.

[0035] The steering gear 2 is installed on the frame 1, and its input end is connected to the tractor power mechanism, and the output end is connected to the external rotating shaft 3 through the primary transmission chain mechanism 5. The external rotating shaft 3 is rotatably installed on the frame 1 through the bearing seat, and the bevel gear rotating shaft 4 is rotatably installed on the lower side of the frame 1 through the bearing seat. The external rotating shaft 3 and the bevel gear rotating shaft 4 are connected through the secondary transmission chain mechanism 6. The first bevel gears 8 are fixedly installed at both ends of the bevel gear rotating shaft 4. One end of the straw cleaning mechanism 7 with an energy storage component is installed with a second bevel gear 9, and the second bevel gear 9 is meshed with the first bevel gear 8. The other end of the straw cleaning mechanism 7 is rotatably connected to the frame 1.

[0036] During operation, the straw cleaning mechanism 7 is symmetrically arranged below the frame 1 and is matched with the side plate below the frame 1 through the rotating shaft and the square bearing seat. The straw cleaning mechanism 7 transmits the tractor power to the rotating shaft of the straw cleaning mechanism 7 through the primary transmission chain mechanism 5, the secondary transmission chain mechanism 6, the first bevel gear 8, and the second bevel gear 9, driving the straw cleaning mechanism 7 to rotate in the opposite direction to both sides of the frame 1. The straw in the working area is cleaned to both sides by the rotation of the straw cleaning mechanism 7 to both sides. During the rotation process, the straw cleaning mechanism 7 touches the ground and is compressed by the reaction force of the ground. When the straw cleaning mechanism 7 leaves the ground, the energy storage component releases energy, which can improve the straw cleaning and scattering effect.

[0037] Two depth-limiting wheels are symmetrically installed on both sides of the two vertical beams below the frame 1, and the operation depth can be adjusted by adjusting the position of the depth-limiting holes on the depth-limiting wheels connected to the machine frame.

[0038] In some embodiments, see Figure 3-5 The straw cleaning mechanism 7 includes a straw cleaning mechanism rotating shaft 71 and a straw cleaning unit 72. The straw cleaning unit 72 is evenly arranged on the straw cleaning mechanism rotating shaft 71. One end of the straw cleaning mechanism rotating shaft 71 is installed with a second bevel gear 9, and the other end is rotatably connected to the frame 1.

[0039] The straw cleaning unit 72 comprises a knife seat 721, a straw cleaning unit housing 722, knife teeth 723, a first energy storage component 724, a second energy storage component 725, a connecting frame 726, and a connecting screw 727. The knife seat 721 is mounted on the straw cleaning mechanism rotating shaft 71. The straw cleaning unit housing 722 is evenly arranged on the knife seat 721 in the circumferential direction by bolts. The first energy storage component 724 is installed in the straw cleaning unit housing 722. The connecting frame 726 is rotatably connected to the middle part of the straw cleaning unit housing 722 and is connected to the shaft of the straw cleaning unit housing 722. The first energy storage component 724 is connected by sliding upward, one end of which is fixed on the inner wall of the straw cleaning unit shell 722, and the other end is connected to the connecting frame 726. The middle part of the connecting frame 726 is connected to the outer end of the straw cleaning unit shell 722 by a connecting screw 727. The end of the connecting screw 727 is threadedly connected with a positioning nut. The connecting screw 727 and the connecting frame 726 and the straw cleaning unit shell 722 are all slidably connected. The second energy storage component 725 is sleeved on the connecting screw 727, and the outer end of the connecting frame 726 is equipped with a knife tooth 723.

[0040] During operation, the tractor inputs power to convert the power direction through the steering gear 2, and transmits the power to the bevel gear rotating shaft 4 under the frame 1 through the primary transmission chain mechanism 5 between the steering gear 2 and the external rotating shaft 3. The first bevel gear 8 and the second bevel gear 9 are installed between the bevel gear rotating shaft 4 and the straw cleaning mechanism rotating shaft 71 so that the two straw cleaning mechanisms 7 can rotate in opposite directions to the two sides of the frame 1. During the rotation of the straw cleaning mechanism 7, after the blade teeth 723 of the straw cleaning unit 72 touch the ground, the first energy storage component 724 and the second energy storage component 725 are compressed and stored due to the reaction force of the ground. When the straw cleaning unit 72 leaves the ground, the energy storage component releases the energy and throws the seedlings and straw to both sides. In this embodiment, the first energy storage component 724 and the second energy storage component 725 both use compression springs.

[0041] In some embodiments, three straw cleaning units 72 are evenly arranged on the rotating shaft 71 of the straw cleaning mechanism, three straw cleaning unit shells 722 are evenly installed on the circumference of the knife seat 721, the arrangement distance between the straw cleaning units 72 is 100 mm, and the staggered installation angle of adjacent straw cleaning units 72 is 40°.

[0042] When working, the three blade teeth 723 on each knife seat 721 are arranged at an equal angle of 120°, and the key groove inside the knife seat 721 and the surface of the rotating shaft 71 of the straw cleaning mechanism cooperate with each other to ensure that the knife seat 721 is fixed in the circumferential direction. The arrangement distance between the straw cleaning units 72 is 100mm, and the staggered installation angle of adjacent straw cleaning units 72 is 40°, so as to realize the continuous and alternating cleaning of the straw on the seedling belt by the straw cleaning mechanism 7 during operation, thereby improving the straw cleaning effect.

[0043] In some embodiments, the primary transmission chain mechanism 5 is respectively connected to the output end of the steering gear 2 and the external rotating shaft 3, and the output end of the steering gear 2 and the end of the external rotating shaft 3 are both equipped with a fixing ring 10 for preventing the primary transmission chain mechanism 5 from falling out.

[0044] During operation, the primary transmission chain mechanism 5 is positioned by the fixing ring 10 to prevent the primary transmission chain mechanism 5 from falling out, thereby ensuring the transmission stability of the transmission mechanism.
