Description

Technical Field

[0001] The invention relates to the technical field of cultivators, in particular to a soil-raising plow structure for a cultivator. Background Art

[0002] The growth of potato tubers requires a loose soil environment and sufficient nutritional conditions. Intertillage and weeding operations can not only increase soil permeability, conserve moisture and resist drought, and create a good living environment, but also remove weeds, prevent weeds from competing with potato seedlings for nutrients, and ensure the growth of potato seedlings.

[0003] The ridge spacing in different regions is different, the soiling height is insufficient, and the soil covering on the film is uneven. Due to the differences in planting in different regions and the deviations in planting in different plots in the region, it is difficult to meet the agronomic requirements of potato growth. The existing soiling device can only complete simple inter-cultivation and soiling of crops, but most of the soiling heights are uneven, and the position of the soiling plow is fixed and cannot be adjusted in real time according to the ridge spacing, which makes it difficult to meet the agronomic requirements of different regions. In addition, when operating in areas with heavy clay soil, the soiling device has a poor soil crushing effect and a large working resistance, which is more obvious, especially when the rigid structure of the soiling plow encounters hard stones, it is more susceptible to trauma and damage.

At this time, the fixing rod 15 is inserted into the socket 101 to ensure that the rocker 13 cannot drive the driving gear 12 to rotate). The position adjustment device includes a gear box 10, a rack 11, a driving gear 12, a rocker 13, a limit nut 14 and a locking assembly. The gear box 10 is used to install the rack 11. The gear box 10 is fixedly connected to the fixed beam 3 by bolts. Therefore, when the gear box 10 moves, it can drive the fixed beam 3 to move. The gear box 10 is fixedly connected with the rack 11. The gear 12 and the rack 11 are meshed with each other, the driving gear 12 is fixedly connected to the rocker 13, the driving gear 12 and the rocker 13 are coaxially arranged, the rocker 13 is inserted in the insertion hole 101, and when the rocker 13 is rotated, the driving gear 12 will be driven to move, and the transmission of the driving gear 12 and the rack 11 will drive the gear box 10 to move. The gear box 10 is provided with a limiting slide groove 1001, and the rocker 13 is inserted in the limiting slide groove 1001. By inserting the rocker 13 in the limiting slide groove 1001, it is used to limit the distance between the rack 11 and the driving gear 12 so that the driving gear 12 and the rack 11 always maintain a meshing state when the motion position is adjusted. The limiting nut 14 is threadedly connected to the rocker 13 and is used to limit the axial movement of the rocker 13. The locking assembly is arranged on the rocker 13 and is used to lock the rotational position of the rocker 13.

[0035] In this embodiment, a plurality of sockets 101 are provided, and the plurality of sockets 101 are arranged at equal intervals on the bracket 1. The rocker 13 is provided with a crank 1301, and the crank 1301 is a hollow structure. The locking assembly includes a fixing rod 15 and a fixing pin 16. The fixing rod 15 is movably inserted into the interior of the crank 1301, and the fixing rod 15 is provided with a plurality of fixing holes 1501. By inserting the fixing pin 16 into the fixing hole 1501, the length of the fixing rod 15 extending out of the crank 1301 is limited.

[0036] A fixing groove 301 is provided inside the fixing beam 3, and the self-excited vibration device is provided in the fixing groove 301. A fixing screw 17 is provided in the fixing groove 301, and the fixing screw 17 is connected to the fixing groove 301 through a fixing nut 18. The fixing frame 4 is rotatably connected to the fixing screw 17. The fixing screw 17 is used to install the fixing frame 4 on the one hand, and on the other hand, the fixing screw 17 is used to install the spring 19. In this embodiment, the fixing beam 3 is composed of two clips 302 that are mutually buckled (as shown in the attached manual). Figure 6 As shown, after the two clamping pieces 302 of the fixed beam 3 are buckled together, a fixing groove 301 is formed inside. Figure 5And the instruction manual Figure 6 The clip 302 is marked separately in the figure, and only the fixed beam 3 as a whole is marked in other drawings of the specification, which is specially explained). Therefore, the fixing screw 17 and the fixing nut 18 cooperate with each other and are also used to fix the two clips 302 of the fixed beam 3 to each other.

[0037] The self-excited vibration device includes a spring 19 and a spring 20. The spring 19 is sleeved on the fixing screw 17. The spring 19 is symmetrically arranged on both sides of the fixing frame 4. The two ends of the spring 19 are respectively connected to the side wall of the fixing groove 301 and the fixing frame 4. Figure 6 As shown, the second spring 20 is arranged perpendicular to the fixing screw 17 , and the second spring 20 is also symmetrically arranged on both sides of the fixing frame 4 , and the two ends of the second spring 20 are respectively connected to the side wall of the fixing groove 301 and the fixing frame 4 .

[0038] Working principle: Before use, the position of the plow body is adjusted according to the planting conditions, potato planting density, soil type and other requirements of different regions. The specific steps are: turn the rocker 13, the rotation of the rocker 13 will drive the driving gear 12 to rotate, and the transmission of the driving gear 12 and the rack 11 will drive the gear box 10 to move, and when the gear box 10 moves, it will drive the fixed beam 3 to move (at this time, the sliding shoe 2 moves along the bracket 1). After the adjustment is completed, the fixed rod 15 in the crank 1301 is inserted into the socket 101 and the length of the fixed rod 15 extending out of the crank 1301 is fixed by inserting the fixing pin 16 into the fixing hole 1501, so as to complete the adjustment of the position of the plow body;

[0039] When the ridging plow is working, the forward movement will encounter greater resistance (the "front", "rear", "left" and "right" here are defined based on the forward movement direction of the ridging plow, which is specially explained). At this time, the spring 20 at the rear end will be compressed. Because the force applied to the ridging plow during the forward ridging process is not balanced, the force applied to the spring 20 at the rear end is constantly changing. When the forward resistance is less than the elastic force of the spring 20 at the rear end, the fixed frame 4 will squeeze the spring 20 at the front end. At this time, the front spring is compressed and stores elastic force. During the whole process, the change in the forward resistance of the ridging plow will be converted into the compression and extension of the spring 20 at both sides of the fixed groove 301, thereby continuously generating self-excited vibration. The setting of the springs 19 on the left and right sides can drive the movement of the fixed frame 4 when the plow wall 7 of the plow body contacts stones or hard soil blocks, thereby driving the entire plow body to deflect and reset, and at the same time generating self-excited vibration, thereby reducing the damage to the plow wall 7 caused by direct collision.

[0040] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
