Description
Technical Field
[0001] The utility model belongs to the technical field of agricultural production tools, and specifically relates to an electric rotary tiller. Background Art
[0002] Crawler tractors are also called "chain track tractors" or "crawler tractors". They drive the rotary tillage equipment to perform rotary tillage on the site. During operation, they climb or move through the pushing action of the crawler tracks. They have the advantages of low unit area pressure on the soil and good adhesion to the soil (not easy to slip). They have better passing performance in wet and soft soils and higher traction efficiency. The unit pressure on the ground is reduced by increasing the ground contact area of the tractor, and the engine power is increased to increase the driving force;
[0003] Traditional fuel crawler tractors are controlled by the power source and use a power transmission shaft to supply the rotary tillage equipment. In actual use, the optimal output elevation angle of the power transmission shaft is above 270°, which cannot effectively control the rotary tillage depth and angle. At the same time, the traditional installation method is bolt fixing, which is not conducive to quick disassembly. Utility Model Content

Since the sliding rod pushed by the second cylinder at the bottom supports the triangular adjustment frame, the adjusting rod drives the triangular adjustment frame to rotate the supporting round rod downward, so as to adjust the rotary tillage height. Further, stop starting the first cylinder and start the second cylinder. The second cylinder pushes the sliding rod to slide along the sliding guide groove and continues to rotate the adjusting rod. Since the length of the first cylinder is fixed, the triangular adjustment frame can only rotate in a circle along the adjusting rod, thereby adjusting the rotation angle of the rotary tillage mechanism. The elastic rod makes the bottom angle height of the triangular adjustment frame lower than the first cylinder, so as to avoid the rotary tillage mechanism from rotating too much when the second cylinder returns and causing dislocation, and can increase the lateral thrust of the first cylinder on the triangular adjustment frame and the longitudinal pulling force of the second cylinder on the triangular adjustment frame. Then, the through round rod block is passed into the connecting and fixing block to complete the connection and fixation of the adjustment mechanism and the rotary tillage mechanism.
[0022] After the adjustment is completed, the drive motor is started, and the drive motor drives the connecting disk to rotate and drives the rotary tillage roller to rotate, and then the operation can begin.
[0023] The crawler tractor is driven by electricity, which effectively solves the difficulty of power transmission. At the same time, it can use a quick installation method to effectively reduce the difficulty of installation, better assist rotary tillage at different angles, effectively increase the uniformity of the equipment and the diversity of use, greatly improve work efficiency, and facilitate use and promotion.

[0042] Helpfully, refer to Figure 6 , 7 As shown, the height adjustment assembly includes a first cylinder 41, one end of the first cylinder 41 is rotatably connected to the fixed connecting plate 39, the other end of the first cylinder 41 is provided with an adjusting rod 42, the adjusting rod 42 is rotatably connected to the first cylinder 41, both ends of the adjusting rod 42 are provided with triangular adjustment frames 43, the adjusting rod 42 is fixedly connected to the top angle of the triangular adjustment frame 43, the bottom corner of the triangular adjustment frame 43 is provided with a supporting round rod 47, both ends of the supporting round rod 47 are provided with through round rod blocks 48, a total of two groups, a sliding guide groove 44 is also provided on the triangular adjustment frame 43, the sliding guide groove 44 is arranged at the bottom edge of the triangular adjustment frame 43 away from the adjusting rod 42, a sliding rod 46 is penetrated and slidably connected in the sliding guide groove 44, and both ends of the sliding rod 46 are provided with a second cylinder 45, and the other end of the second cylinder 45 away from the sliding rod 46 is rotatably connected to the second group of fixed connecting plates 39 away from the first cylinder 41.
[0043] Specifically, start the first cylinder 41 to push the adjusting rod 42 to tilt toward the direction of the rotary tillage mechanism 5. Since the sliding rod 46 pushed by the second cylinder 45 at the bottom supports the triangular adjusting frame 43, the adjusting rod 42 drives the triangular adjusting frame 43 to rotate the supporting round rod 47 downward, thereby achieving the adjustment of the height of the rotary tillage equipment.
[0044] Furthermore, the first cylinder 41 is stopped and the second cylinder 45 is started. The second cylinder 45 pushes the sliding rod 46 to slide along the sliding guide groove 44, and the adjusting rod 42 continues to be rotated. Since the length of the first cylinder 41 is fixed, the triangular adjusting frame 43 can only rotate in a circle along the adjusting rod 42, thereby realizing the rotation angle adjustment of the rotary tillage mechanism 5. The best solution for this mechanism to realize the above method is to start the first cylinder 41 and the second cylinder 45 at the same time, and control the position adjustment of the triangular adjusting frame 43 to complete the lifting and rotation.
[0045] Helpfully, refer to Figure 7 As shown, the triangular adjustment frame 43 is also provided with an elastic rod 49, one end of the elastic rod 49 is rotatably connected to the bottom corner of the triangular adjustment frame 43 away from the supporting round rod 47, and the other end of the elastic rod 49 is rotatably connected to the two ends of the fixed connecting plate 39 provided with the first cylinder 41.
[0046] In practice, an acute angle is formed between the elastic rod 49 and the second cylinder 45, so as to avoid the triangle adjustment frame 43 from being rotated too much and causing misalignment when the second cylinder 45 returns, and to increase the lateral thrust of the first cylinder 41 on the triangle adjustment frame 43 and the longitudinal pulling force of the second cylinder 45 on the triangle adjustment frame 43, so as to avoid the non-directional movement of the sliding rod 46 when it slides to the middle along the sliding guide groove 44.
[0047] Working principle of this utility model:
[0048] After the operator connects the battery 11 to the motor of the crawler tractor 1, he continues to connect the drive motor 51 through the through hole of the fixing plate 56 to complete the preliminary preparation work;
[0049] The connecting force rod 38 is parallel to the rotary tillage direction, and then the connecting round rod 37 is pushed into the notch socket 311, squeezing the notch top rod block 35 to move in the direction of the rotating top rod block 32, and at the same time rotating the C-shaped hook rod, passing the end of the C-shaped hook rod into the rectangular through groove 381. Due to the thrust of the top rod spring 33, the connecting round rod 37 pushes the connecting force rod 38 away from the C-shaped hook rod, and one end of the C-shaped hook rod passes into the rectangular through groove 381, so that the fork quick connection block 31 can fix the connecting force rod 38, thereby driving the adjustment mechanism 4 to operate;
[0050] To cope with different sites, the rotary tillage equipment needs to change different angles and heights. The first cylinder 41 is started to push the adjusting rod 42 to tilt in the direction of the rotary tillage mechanism 5. Since the sliding rod 46 pushed by the second cylinder 45 at the bottom supports the triangular adjusting frame 43, the adjusting rod 42 drives the triangular adjusting frame 43 to rotate the supporting round rod 47 downward, so as to adjust the rotary tillage height. Further, the first cylinder 41 is stopped and the second cylinder 45 is started. The second cylinder 45 pushes the sliding rod 46 to slide along the sliding guide groove 44, and the adjusting rod 42 is continued to rotate. Since the first cylinder 41 is long, the adjusting rod 42 is rotated. The degree of rotation is fixed, and the triangular adjustment frame 43 can only rotate in a circle along the adjustment rod 42, thereby realizing the rotation angle adjustment of the rotary tillage mechanism 5. The elastic rod 49 makes the bottom angle height of the triangular adjustment frame 43 lower than the first cylinder 41, so as to avoid the rotary tillage mechanism 5 from rotating too much and causing dislocation when the second cylinder 45 returns, and can increase the lateral thrust of the first cylinder 41 on the triangular adjustment frame 43, and the longitudinal pulling force of the second cylinder 45 on the triangular adjustment frame 43. After that, the through round rod block 48 is passed into the connecting and fixing block 52, so as to complete the connection and fixation of the adjustment mechanism 4 and the rotary tillage mechanism 5.
[0051] After the adjustment is completed, the driving motor 51 is started, and the driving motor 51 drives the connecting plate 57 to rotate and drives the rotary tilling roller 53 to rotate, and then the operation can be started.
