Description

Technical field:

[0001] The utility model relates to the technical field of seed drills, in particular to a ground wheel mud shoveling device. Background technology:

[0002] At present, the seeder relies on the ground wheel transmission to drive the seed box to rotate for sowing. When sowing on wet terrain, the ground wheel will stick to pieces of soil. These soil pieces may cause the ground wheel to stop rotating or rotate intermittently, which directly affects the sowing effect. Therefore, a mud shoveling device is needed to remove the soil pieces stuck on the ground wheel.

[0003] The existing ground wheel mud shoveling device uses the torsional force of the torsion spring to make the mud shoveling plate close to the ground wheel to achieve the mud shoveling effect. However, the elastic force of the torsion spring in this way cannot be flexibly adjusted according to actual conditions. When sowing on terrain with high viscosity of ground soil and a lot of straw and weeds on the ground, if the force with which the mud shoveling plate sticks to the ground wheel is too small, the mud shoveling plate may directly flip up and cause the torsion spring to fail. When sowing on terrain with low viscosity of ground soil and a few straw and weeds, if the force with which the mud shoveling plate sticks to the ground wheel is too large, the wear of the mud shoveling plate will be accelerated. Utility model content:

[0004] In order to make up for the deficiencies of the existing technical problems, the purpose of the utility model is to provide an adjustment component to rotate the adjustment nut to change the distance between the adjustment plate and the buffer plate to solve the problem that the elastic force cannot be flexibly adjusted according to actual conditions.

[0005] In order to solve the problems of the existing technology, the technical solution of the utility model is as follows: a ground wheel mud shoveling device, including a mounting frame and a mud shoveling plate, the outer wall of the mounting frame is connected to the mounting plate by bolts, the outer wall of the mud shoveling plate is connected to the connecting plate by bolts, the top of the connecting plate is fixedly connected to the buffer plate, the outer wall of the buffer plate is provided with a sliding groove, the outer wall of the adjusting bolt is slidably connected to the inner wall of the sliding groove, the outer wall of the mounting plate is threadedly connected to the adjusting bolt, the outer wall of the adjusting bolt is sleeved with a spring, the outer wall of the adjusting bolt is provided with an adjusting assembly for adjusting the elastic force of the spring, and a limiting assembly is provided between the buffer plate and the mounting plate to support the buffer plate to slide linearly.

[0006] Preferably, the adjustment assembly includes an adjustment plate slidably connected to the outer wall of the adjustment bolt, the two ends of the spring are fixedly connected to the opposite sides of the buffer plate and the adjustment plate respectively, the outer wall of the adjustment bolt is threadedly connected with an adjustment nut, and one side of the adjustment nut is rotatably connected to one side of the adjustment plate.

[0007] Preferably, the limiting assembly includes a limiting plate fixedly connected to one side of the mounting plate, the outer wall of the buffer plate is provided with a limiting groove, and the outer wall of the limiting plate is slidably connected to the inner wall of the limiting groove.

[0008] Compared with the prior art, the advantages of the present invention are as follows:

[0009] The utility model provides an adjustment component, and by rotating the adjusting nut clockwise, the distance between the adjusting plate and the buffer plate is reduced, that is, the spring is squeezed, so that the force with which the shovel plate is pressed against the ground wheel is increased, thereby preventing the shovel plate from directly flipping up and causing the torsion spring to fail when sowing on terrain with high viscosity of ground soil and many straws and weeds on the ground. By rotating the adjusting nut counterclockwise, the distance between the adjusting plate and the buffer plate is increased, that is, the elastic force of the spring is reduced, so that the force with which the shovel plate is pressed against the ground wheel is reduced, thereby reducing the wear of the shovel plate when sowing on terrain with low viscosity of ground soil and few straws and weeds.

[0010] The utility model provides an adjustment component. Since the raw material round tube of the seed drill wheel is not an ideal circle, the downward pressure between the mud shoveling plate and the round tubes with different roundness can be adjusted by rotating the adjustment nut to adjust the elastic force of the spring, so as to achieve the most ideal mud shoveling effect, thereby effectively improving the working efficiency and practicality of the ground wheel mud shoveling device.

[0011] The utility model connects the mounting plate with the outer wall of the mounting frame by bolts, so that the mud shovel plate device as a whole can be replaced separately after being damaged, avoiding the situation where the torsion spring on the original single mud shovel plate fails and the entire round tube needs to be dismantled to replace and repair the torsion spring, making the operation simpler and more convenient.

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

The shovel board 2 contacts the ground wheel on the seed drill, and the shovel board 2 and the connecting plate 4 are a detachable structure. One mounting plate 3 corresponds to a connecting plate 4 and a buffer plate 5. When the shovel board 2 shovels the soil on the ground wheel, the soil will react to push the buffer plate 5 to move, and the inner wall of the upper limit groove 12 on the buffer plate 5 slides along the outer wall of the limit plate 11, that is, the buffer plate 5 always maintains linear motion, and the mounting plate 3 is connected to the outer wall of the mounting frame 1 by bolts, so that the shovel board 2 device as a whole can be replaced separately after damage, avoiding the failure of the torsion spring on the original single shovel board 2, and the entire round tube has to be removed to replace and repair the torsion spring, making the operation simpler and more convenient.

[0019] See also Figure 2-4The adjusting assembly includes an adjusting plate 9 that is slidably connected to the outer wall of the adjusting bolt 6. The two ends of the spring 7 are fixedly connected to the opposite sides of the buffer plate 5 and the adjusting plate 9. The outer wall of the adjusting bolt 6 is threadedly connected with an adjusting nut 10. One side of the adjusting nut 10 is rotatably connected to one side of the adjusting plate 9. Specifically, the friction force between the adjusting bolt 6 and the adjusting plate 9 is less than the torsional force of the adjusting spring 7. That is, when the adjusting bolt 6 is rotated, the adjusting plate 9 will not be driven to rotate, but will only push the adjusting plate 9 to move linearly. The spring 7 is always in a compressed state. Turning the adjusting nut 10 clockwise will drive the adjusting plate 9 to slide inward along the surface of the adjusting bolt 6. The distance between the adjusting plate 9 and the buffer plate 9 is reduced, which will increase the elastic force of the spring 7 and the force of the spring 7 on the buffer plate 5, which can increase the force of the shovel plate 2 against the ground wheel. The force with which the mud plate 2 is pressed against the ground wheel is reduced. By setting an adjustment component, the adjusting nut 10 is rotated clockwise to reduce the distance between the adjusting plate 9 and the buffer plate 9, that is, the spring 7 is squeezed, which can increase the force with which the mud plate 2 is pressed against the ground wheel. Therefore, when sowing on a terrain with high viscosity of the ground soil and a lot of straw and weeds on the ground, the mud plate 2 is prevented from directly flipping up and causing the torsion spring to fail. The adjusting nut 10 is rotated counterclockwise to increase the distance between the adjusting plate 9 and the buffer plate 9, that is, the elastic force of the spring 7 is reduced, which can reduce the force with which the mud plate 2 is pressed against the ground wheel. Therefore, when sowing on a terrain with low viscosity of the ground soil and few straw and weeds, the wear of the mud plate 2 is reduced. By setting an adjustment component, since the raw material round tube of the seeder ground wheel is not an ideal round tube, the elastic force of the spring 7 can be adjusted by rotating the adjusting nut 10 to adjust the downward pressure between the mud plate 2 and the tube with different roundness, so that the mud shoveling effect reaches the most ideal state, effectively improving the working efficiency and practicality of the ground wheel mud shoveling device.

[0020] When in use, when the shovel plate 2 shovels the soil on the ground wheel, the soil will react to push the shovel plate 2, the shovel plate 2 drives the connecting plate 4 to move, and the connecting plate 4 drives the buffer plate 5 to move. The inner wall of the upper limit groove 12 of the buffer plate 5 slides along the outer wall of the limit plate 11, and the buffer plate 9 squeezes the spring 7. The reciprocating motion of the spring 7 makes the shovel plate 2 close to the ground wheel. When sowing on a terrain with high viscosity of soil blocks and more straw and weeds on the ground, the operator turns the adjusting nut 10 clockwise, and the adjusting nut 10 drives the adjusting plate 9 to slide inward along the surface of the adjusting bolt 6. The adjusting plate 9 and the buffer plate 9 are reduced, which squeezes the spring 7, thereby increasing the elastic force of the spring 7 and increasing the force of the spring 7 on the buffer plate 5. Since the buffer plate 5 is connected to the shovel plate 2 through the connecting plate 4, the force of the shovel plate 2 against the ground wheel can be increased. When sowing on a terrain with low viscosity of ground soil and less straw and weeds, the operator rotates the adjusting nut 10 counterclockwise, and the adjusting nut 10 drives the adjusting plate 9 to slide outward. The distance between the adjusting plate 9 and the buffer plate 9 increases, namely, the elastic force of the spring 7 decreases, which can reduce the force of the shovel plate 2 against the ground wheel.
