Description

Technical Field

[0001] The utility model relates to the technical field of ridging machines, in particular to a small agricultural ridging machine. Background Art

[0002] Ridge forming technology in potato planting is an important cultivation measure, which can significantly improve the yield and quality of potatoes. Agricultural small ridgers are mainly used for ridging operations after field plowing of economic crops such as potatoes and vegetables. In potato planting, ridgers can create ridges that are conducive to drainage and irrigation, preventing excessive water from causing root rot.

[0003] When planting on ridges, choose a plot with deep soil, fertile soil, and good drainage and water retention. Apply sufficient base fertilizer before ridges, mainly organic fertilizer, with an appropriate amount of chemical fertilizer. The organic fertilizer should be fully decomposed, and the chemical fertilizer should be formulated according to the soil nutrient status and the fertilizer requirements of potatoes. Ridges should be formed according to the predetermined ridge distance and ridge height, and the ridge surface should be flat and the ridge ditch should be unobstructed. When planting potatoes on ridges, pay attention to reasonable density to ensure that there is enough growth space between the plants.

[0004] After searching, a small agricultural ridger with application number 202321136821.9 was found. The soil can be gathered and formed into a ridge shape through two retaining plates and the top surface limiting effect of the outer shell. The scraper roller can scrape the side of the ridge to make the soil tighter and avoid collapse.

[0005] In the existing technical solutions, the ridger will inevitably come into contact with the soil when making ridges. However, when encountering moist soil, the moist soil will adhere to the outer surface of the ridger. If the soil attached to the outer surface is not cleaned in time, the soil will gradually accumulate and stick to the ridger, making it impossible to effectively gather the soil, affecting the working efficiency and effect. Summary of the invention

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] The utility model provides a technical solution:

[0029] See also Figures 1 to 4A small agricultural ridging machine includes a hand-held rotary tillage tractor frame 1, an engine 2 is fixedly installed at the front upper end of the hand-held rotary tillage tractor frame 1, and the power output end of the engine 2 is connected to a gearbox 4 fixedly installed on the hand-held rotary tillage tractor frame 1. A V-belt and a clutch are also provided between the engine 2 and the gearbox 4. After passing through the V-belt and the clutch, the power of the engine 2 enters the gearbox 4 for further transmission and speed change. The gearbox 4 is the core component of the tractor transmission system. The gearbox 4 realizes the speed change and torque change of the power through the gear transmission inside. The power after the speed change of the gearbox 4 is transmitted through the output shaft. The connection and power transmission between the engine 2 and the gearbox 4 are prior art, which will not be described in detail here. The driving wheels 3 are rotatably installed on both sides of the hand-held rotary tillage tractor frame 1. The power generated by the engine 2 needs to be transmitted to the driving wheels 3 through the transmission system, so as to drive the tractor forward or backward. The transmission system includes a plurality of components such as a clutch, a gearbox 4, and a transmission rod, which work together to convert the power of the engine 2 into the driving force on the driving wheel 3. The connection structure and power transmission here are prior art, which will not be described in detail here. A rotary tiller 5 is fixedly installed at the rear end of the hand-held rotary tiller tractor frame 1, and the rotary tiller 5 is connected to the hand-held rotary tiller tractor through a specific connection device, such as a three-point suspension system. This connection device not only ensures that the rotary tiller 5 can be stably fixed on the tractor, but also realizes the effective transmission of power. Inside the rotary tiller 5, there is a series of transmission gears that further transmit the power output by the tractor to working parts such as rotary tiller blades. When the power is transmitted to the rotary tiller blades, the blades start to rotate and cut the soil. Through the rotation and cutting action, the soil is deeply loosened, broken and becomes soft and fertile. The connection structure and power transmission here are prior art and will not be described in detail here.

[0030] A ridging transmission assembly 8 is provided at the rear end of the rotary tiller 5, and a self-cleaning assembly 9 is provided between the ridging transmission assembly 8 and the rotary tiller 5; a ridging control assembly 7 is also provided between the ridging transmission assembly 8 and the rotary tiller 5, and the ridging control assembly 7 includes a height adjustment suspension 701 rotatably mounted on the left and right side walls of the rotary tiller 5, a transmission shaft 802 is rotatably mounted between the inner sides of the two height adjustment suspensions 701, and two symmetrically arranged ridging cones 801 are fixedly mounted at both ends of the transmission shaft 802, a bearing 806 is fixedly mounted on the upper end surface of the rotary tiller 5, and an intermediate shaft 807 is rotatably penetrated inside the bearing 806; the left end of the intermediate shaft 807 is connected to the second toothed belt member 804, and the right end of the intermediate shaft 807 is connected to the first toothed belt member 803, the power input end of the second toothed belt member 804 is connected to the drive shaft 805, and the power output end of the first toothed belt member 803 is connected to the transmission shaft 802, and the toothed belt member includes two gears and a gear belt, and the gear belt sleeve is meshed on the gear. The self-cleaning component 9 includes an assembly part 901 fixedly mounted on the rear side wall of the rotary tiller 5, a scraper 902 that fits the ridging cone 801 is slidably mounted inside the assembly part 901, an assembly cavity 903 is provided inside the assembly part 901, a plurality of springs 904 are fixedly mounted inside the assembly cavity 903, and the scraper 902 is elastically slidably connected to the assembly part 901 via the springs 904.

[0031] By adopting the above technical solution, the power after the speed change of the gearbox 4 is transmitted through the output shaft, and the output shaft is fixedly connected to the drive shaft 805. The drive shaft 805 is fixedly connected to a gear of the second toothed belt member 804. The second toothed belt member 804 can realize power transmission, and the other gear of the second toothed belt member 804 is fixed to one end of the intermediate shaft 807. The intermediate shaft 807 is rotatably installed on the top of the rotary tiller 5 housing through the bearing 806 and the bearing seat. The rotation of the intermediate shaft 807 can transmit power to a gear of the first toothed belt member 803. The other gear of the first toothed belt member 803 is fixedly installed on the transmission shaft 802, thereby driving the transmission shaft 802 to rotate on the height adjustment suspension 701, which can drive the ridging cone disk 801 to rotate. The two ridging cone disks 801 rotate symmetrically at the same speed and direction, ensuring that the soil is evenly stressed during the ridging process, thereby forming a regular ridge. When the ridging cone 801 rotates, the scraper 902 is attached to the conical surface of the ridging cone 801. During the ridging operation, the outer surface of the ridging cone 801 is easily attached with dirt and impurities. These attachments will affect the normal operation of the ridger. The existence of the scraper 902 can effectively reduce these attachments and keep the outer surface of the ridger clean; the clean ridging cone 801 can complete the ridging operation more accurately, avoiding the problems of inconsistent ridging height and width caused by too many attachments, thereby ensuring the planting quality of potatoes; and during the operation, if the ridger needs to be frequently stopped for cleaning due to too many attachments, the operation efficiency will be greatly reduced. The existence of the scraper 902 can reduce this downtime and improve the continuity of the operation. The spring 904 is connected to the inner wall of the scraper 902 to ensure that the scraper 902 has a suitable force to clean the ridging cone 801 when scraping and cleaning, thereby ensuring the cleaning effect and avoiding scratches on the surface of the ridging cone 801.

[0032] Specifically, Figure 1 , Figure 2 and Figure 4 As shown, the ridging control assembly 7 also includes a bearing shaft 706 fixed to the left and right side walls of the rotary tiller 5, a fixed locking seat 705 is fixedly installed on the outer side wall of the left height adjustment suspension 701, a pull rod 702 is fixedly installed on the upper end of the fixed locking seat 705, and a connecting seat 703 is fixedly installed on the upper end of the pull rod 702. A hand handle 6 is fixedly installed at the rear end of the hand handle 6, and a hydraulic cylinder 704 is fixedly installed on the left side wall of the hand handle 6. The power output end of the hydraulic cylinder 704 is rotatably connected to the connecting seat 703. The rear end of the height adjustment suspension 701 is fixedly installed with an axle frame 10, and two rear wheels 11 are rotatably installed at both ends of the axle frame 10.

[0033] By adopting the above technical solution, when in use, the hydraulic cylinder 704 is started, and the hydraulic cylinder 704 can pull the connecting seat 703 to move. The connecting seat 703 can drive the height adjustment suspension 701 to move through the pull rod 702 and the fixed locking seat 705. The height adjustment suspension 701 can rotate on the two side walls of the rotary tiller 5 through the bearing shaft 706, so that the height of the height adjustment suspension 701 can be adjusted, so that the position of the ridging transmission component 8 on the height adjustment suspension 701 can be adjusted, so that the ridging cone 801 of the ridging transmission component 8 can be ensured to have a suitable height with the ground, so that by adjusting the height of the ridging device, it can be better adapted to different terrains, ensuring the stability and efficiency of the ridging operation; and different crops have different requirements for soil depth and ridge height. For example, root crops such as potatoes require a deeper soil layer to promote the growth of tubers, while leafy crops may require a shallower ridge height. By adjusting the height of the ridging device, the growth needs of different crops can be met. The rear wheel 11 can provide auxiliary support and compact the furrows after ridging. The movement of the rear wheel 11 follows the traction of the driving wheel 3 .

[0034] Working principle: When in use, start the hydraulic cylinder 704, and the hydraulic cylinder 704 can pull the connecting seat 703 to move. The connecting seat 703 can drive the height adjustment suspension 701 to move through the pull rod 702 and the fixed locking seat 705. The height adjustment suspension 701 can rotate on the two side walls of the rotary tiller 5 through the load-bearing shaft 706, so that the height of the height adjustment suspension 701 can be adjusted, so that the position of the ridging transmission assembly 8 on the height adjustment suspension 701 can be adjusted, so as to ensure that the ridging cone disk 801 of the ridging transmission assembly 8 has a suitable height with the ground. When the height is adjusted, the driving shaft 805 rotates to work, and the driving shaft 805 is fixedly connected to a gear of the second toothed belt member 804. The second toothed belt member 804 can realize power transmission, and another gear of the second toothed belt member 804 is fixedly connected to the second toothed belt member 804. It is fixed at one end of the intermediate shaft 807, and the intermediate shaft 807 is rotatably installed on the top of the rotary tiller 5 housing through the bearing 806 and the bearing seat. The rotation of the intermediate shaft 807 can transmit power to a gear of the first toothed belt member 803, and the other gear of the first toothed belt member 803 is fixedly installed on the transmission shaft 802, thereby driving the transmission shaft 802 to rotate on the height adjustment suspension 701, which can drive the ridging cone disk 801 to rotate. The two ridging cone disks 801 rotate symmetrically at the same speed and direction, ensuring that the soil is evenly stressed during the ridging process, thereby forming a regular ridge; when the ridging cone disk 801 rotates, the scraper 902 fits on the conical surface of the ridging cone disk 801, and the spring 904 is connected to the inner wall of the scraper 902, which can ensure that the scraper 902 has a suitable force to clean the ridging cone disk 801 when scraping and cleaning.
