Description

Technical Field

[0001] The present invention relates to the technical field of agricultural machinery, and specifically refers to a micro-tiller. Background Art

[0002] In modern agricultural production, the demand for small-scale farm operation equipment is increasing day by day. Especially in mountainous areas, hilly areas and other regions with complex terrains and small plots, traditional large agricultural machinery is difficult to operate. Manual operations such as trenching and sowing are labor-intensive, inefficient, and the operation quality is difficult to guarantee. Existing micro-tilling equipment has relatively single functions, and most can only achieve one of the functions of trenching or sowing. If trenching and sowing operations need to be completed, multiple devices need to be used in sequence, which not only increases the equipment purchase cost but also reduces the operation efficiency. Some integrated micro-tillers have the functions of trenching and sowing, but the trenching depth and sowing row spacing are difficult to flexibly adjust according to different crops and soil conditions, restricting the application range of the equipment. In addition, some micro-tillers have unreasonable structural designs. When encountering complex terrains, the operation stability is poor, faults are likely to occur, and the maintenance and component replacement of the equipment are inconvenient, increasing the use cost. Therefore, it is of great practical significance to develop a micro-tiller with integrated functions, flexible adjustment, stable structure and convenient maintenance. Summary of the Invention

[0030] Embodiment:

[0031] Combined with the attached Figures 1-6 , this embodiment discloses a micro-tiller, including a frame 1. Along the moving direction of the frame 1, a ditching assembly 2, a seeding assembly 3, and a main traveling assembly 4 are sequentially arranged from front to back on the upper part of the frame 1. A secondary traveling assembly 5 is arranged at the lower part of one end of the frame 1 away from the main traveling assembly 4;

[0032] When the micro-tillage machine is put into operation, the main travel assembly 4 and the auxiliary travel assembly 5 work together to provide power and support for the whole machine. The main travel assembly 4 includes a drive box 401 arranged on the upper part of the frame 1, and the drive box 401 is connected to the main transmission shaft 402 extending out of the frame 1, and the two ends of the main transmission shaft 402 are respectively connected to the main travel wheels 403. After the power device in the drive box 401 is started, the main transmission shaft 402 is driven to rotate, and then the main travel wheel 403 is rotated to drive the micro-tillage machine forward. The auxiliary travel assembly 5 includes an auxiliary transmission shaft 501 arranged at the lower part of the frame 1, and the two ends of the auxiliary transmission shaft 501 are respectively provided with auxiliary travel wheels 502. The auxiliary transmission shaft 501 is connected to the lower part of the frame 1 through a bearing bracket 503, and the auxiliary travel wheel 502 rolls on the ground to assist the main travel wheel 403 to support and promote the micro-tillage machine to move smoothly.

[0033] During the forward movement of the micro-tiller, the ditching assembly 2 starts to work. The ditching assembly 2 includes a ditching bracket 201 and several ditching structures 202 detachably arranged on the upper part of the ditching bracket 201. Height adjustment assemblies 203 connected to the frame 1 are respectively arranged on both sides of the ditching bracket 201. The ditching bracket 201 is composed of several rows of horizontal brackets 201a arranged in parallel and several vertical brackets 201b connected between the horizontal brackets 201a. The ditching structures 202 are arranged on the horizontal brackets 201a, and the height adjustment assemblies 203 are respectively arranged at both ends of the horizontal brackets 201a. The height adjustment assembly 203 includes a moving plate 203a connected to both ends of the horizontal bracket 201a. An electric screw 203b is arranged in the middle of the moving plate 203a in a matching manner, and guide rods 203c are arranged on both sides in a matching manner. The electric screw 203b and the guide rods 203c are arranged between the frame 1 and the screw bracket 203d. The bottom of the electric screw 203b is rotatably connected to the frame 1, and the top passes through the screw bracket 203d and is then connected to the first motor 203e. The bottom of the guide rod 203c is connected to the frame 1, and the top is connected to the screw bracket 203d. When it is necessary to adjust the ditching depth, the first motor 203e is started. The first motor 203e drives the electric screw 203b to rotate. Under the guiding action of the guide rod 203c, the moving plate 203a moves up and down along the electric screw 203b, thereby adjusting the height of the ditching bracket 201 and realizing the control of the ditching depth. The ditching structure 202 includes a lower hoop 202a and an upper hoop 202b clamped on the horizontal bracket 201a. The lower hoop 202a and the upper hoop 202b are connected to each other by bolts. One side of the lower hoop 202a is rotatably connected to the lower part of the ditching movable bracket 202c and is connected to the upper part of the ditching fixed bracket 202d. A ditching rod 202e extending towards the bottom of the frame 1 is connected to the ditching movable bracket 202c. One end of the ditching movable bracket 202c far away from the lower hoop 202a is connected to the ditching fixed bracket 202d through a spring damper 202f. A first long hole 101 corresponding to the ditching structure 202 is arranged on the frame 1. The ditching rod 202e is an arc-shaped rod extending out of the first long hole 101, and a ditching head 202g is arranged at the bottom. As the micro-tiller moves forward, the ditching head 202g contacts the ground and performs ditching operations driven by the ditching bracket 201. The spring damper 202f can buffer the ditching movable bracket 202c when encountering uneven ground or obstacles, ensuring the stability and continuity of the ditching operations.

[0034] After the trench digging is completed, the seeding assembly 3 starts to work. The seeding assembly 3 includes a seeding box 301 mounted on the upper part of the frame 1. A feeding bin 302 communicating with the seeding box 301 is arranged at the top of the seeding box 301, and seeds enter the seeding box 301 from the feeding bin 302. A spiral feeder 303 is arranged in the seeding box 301. One end of the spiral feeder 303 passes through the seeding box 301 and is in transmission connection with a second motor 304. When the second motor 304 is started, the spiral feeder 303 rotates, and conveys the seeds from the seeding box 301 to several seeding tubes 305 at the bottom. The seeding tubes 305 are adjustably connected to the frame 1 through mounting clips 306. A second long hole 102 corresponding to the first long hole 101 is opened at the bottom of the frame 1 under the seeding box 301. A third long hole 103 is opened on the side of the second long hole 102 away from the first long hole 101. The seeding tubes 305 at the bottom of the seeding box 301 extend out of the bottom of the frame 1 through the second long hole 102. The mounting clip 306 is clamped outside the seeding tube 305. The mounting clip 306 includes a C-shaped clip 306a clamped between the first long hole 101 and the third long hole 103. A locking bolt 306b for locking with the side wall of the third long hole 103 is further arranged at one end of the C-shaped clip 306a located in the third long hole 103. According to the spacing of the trench digging assembly, the lateral position of the seeding tube 305 can be adjusted by adjusting the position of the mounting clip 306 in the first long hole 101 and the third long hole 103, so as to realize seeding with different row spacings. After the position is adjusted, tighten the locking bolt 306b to fix the seeding tube 305. The seeding tubes 305 spread the seeds into the trenches dug by the trench digging assembly 2, completing the seeding operation.

[0035] In addition, a connecting bracket 6 arranged at one end of the frame 1 can be used to connect other supporting devices or components to expand the functions of the micro-tiller. Through the orderly cooperation of each component, the whole micro-tiller realizes the integrated operation of operations such as trench digging and seeding, improving the efficiency and quality of agricultural production.
