Description

Technical Field

[0001] The utility model belongs to the technical field of seed drills, and in particular relates to a steering device of a small vegetable seed drill. Background Art

[0002] The vegetable seed drill is an agricultural machine mainly used for seeding vegetable seeds in rows. It is suitable for sowing a variety of vegetable seeds. This seed drill can save seedlings, strengthen seedlings, and increase yields without thinning. It is an important tool in vegetable planting. The use of vegetable seed drills can improve sowing efficiency, ensure uniformity and consistency of sowing, and thus help improve the growth quality and yield of crops.

[0003] The steering of the drill seed machine is achieved by the travel wheel driving the seed wheel to rotate, thereby realizing the sowing operation. When the drill seed machine is operating, the seeds are discharged from the seed cup in the seed box into the seed tube according to the required sowing amount, and fall into the opened groove through the furrow opener, and then the seeds are covered and compacted by the soil covering and pressing device. This working method ensures that the seeds can be evenly distributed in the opened groove, providing good conditions for the growth of crops, but there are still the following deficiencies in actual use: From a practical point of view, the steering device of the drill seed machine has a single power, and long-term steering at only one position or a slow return rate may cause the sowing work frame to become unstable or deviate from the predetermined path during operation, thereby affecting the uniformity and efficiency of sowing.

[0004] Therefore, a steering device for a small vegetable seed drill is needed to solve the problems existing in the prior art. Utility Model Content

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The following further describes the present utility model in conjunction with embodiments.

[0021] Please refer to Figures 1-3, the present utility model provides a steering device for a small vegetable dibbler, including: a chassis 1, the front end of the chassis 1 is triangular, and the rear end of the chassis 1 is rectangular. On both sides of the upper end of the rectangular chassis 1, second fixing plates 4 or third fixing plates 5 are respectively fixedly connected before and after. A regulating rod 6 is slidably connected to the middle of the second fixing plate 4 and the third fixing plate 5 on one side. The rear ends of the symmetric regulating rods 6 are both slidably connected to a regulating plate 7. A first fixing plate 3 is slidably connected to the middle of the regulating plate 7. A connecting block 604 is fixedly connected to the front end of the outer surface of the regulating rod 6. The middle of the rear side of the connecting block 604 is fixedly connected to one end of the push rod 204 of the electric push rod 2. The electric push rod 2 further includes a control device 201, a motor 203 and a sliding seat 202. The front ends of the symmetric regulating rods 6 are fixedly connected to a fixing rod 10 through a connecting component 9. Wheels 11 are connected to both ends of the fixing rod 10 by bearings. The middle outer surface of the fixing rod 10 is slidably connected to the main body of the vegetable dibbler through a fixing component 8.

[0022] Further, as Figure 1 shown, it is worth specifically explaining that fixing disks 601 are fixedly connected to the middle of the outer surface of the regulating rod 6 between the second fixing plate 4 and the third fixing plate 5. Springs 602 are fixedly connected to both ends of the fixing disks 601. The other ends of the symmetric springs 602 are respectively fixedly connected to one side of the second fixing plate 4 or the third fixing plate 5. Grooves 603 are provided on the upper and lower sides of the outer surface of the rear end of the regulating rod 6. Through the regulating rod 6, that is, when the electric push rod 2 drives the push rod 204 and the symmetric regulating rods 6 to move back and forth, since fixing disks 601 are provided in the middle of the symmetric regulating rods 6 and springs 602 are provided on both sides of the fixing disks 601, the steering of the small vegetable dibbler can be quickly returned to the straight position, increasing the safety factor, and further increasing the practicability of the device.

[0023] Further, as Figure 1 shown, it is worth specifically explaining that second grooves 703 are provided in the middle of both ends of the regulating plate 7. Second connecting shafts 701 are fixedly connected to both the upper and lower ends of the regulating plate 7 at the second grooves 703. The middle outer surfaces of the second connecting shafts 701 are slidably connected to the middle of the grooves 603 provided at the rear ends of the regulating rods 6. Baffles 702 are fixedly connected to the outer surfaces of the second connecting shafts 701 at both the upper and lower ends of the grooves 603. Since both ends of the regulating plate 7 are respectively slidably connected to both ends of the symmetric regulating rods 6, one side of the regulating rod 6 can drive the other side of the regulating rod 6 to move in the opposite direction through the regulating plate 7. Through the baffles 702, the movement track of the regulating plate 7 is further restricted.

[0024] Further, as Figure 3As shown in the figure, it is worth specifically explaining that the lower end of the first fixing plate 3 is fixedly connected to the middle of the upper rear side of the rectangular chassis 1, and a first groove 301 is provided in the middle of the rear side of the first fixing plate 3. At the upper and lower ends of the middle of the first fixing plate 3 located in the first groove 301, first connecting shafts 302 are fixedly connected. The outer surface of the first connecting shaft 302 is slidably connected to the middle of the adjusting plate 7. And both sides of the first fixing plate 3 located in the first groove 301 are designed with arc surfaces. Through the first fixing plate 3, the relative positions and movement trajectories of the symmetric adjusting rods 6 are restricted. And because both sides of the first fixing plate 3 located in the first groove 301 are designed with arc surfaces, it is convenient for the operation of the adjusting plate 7.

[0025] The working process of this solution is as follows: The electric push rod 2 drives the push rod 204 to move back and forth, thereby driving the connecting block 604 to move back and forth, thereby driving the adjusting rod 6 on this side to move back and forth, thereby driving the steering of this small vegetable dibbler. And at the same time, because the rear end of the adjusting rod 6 on this side is slidably connected to one end of the adjusting plate 7, and the other end of the adjusting plate 7 is slidably connected to the rear end of the adjusting rod 6 on the other side, and at the same time the middle position of the adjusting plate 7 is restricted, so the back-and-forth movement of the adjusting rod 6 on this side drives the adjusting rod 6 on the other side to make the opposite back-and-forth movement, that is, this small vegetable dibbler steers. When the electric push rod 2 drives the push rod 204 and the symmetric adjusting rods 6 to move back and forth, since a fixed disk 601 is provided in the middle of the symmetric adjusting rods 6 and springs 602 are provided on both sides of the fixed disk 601, the steering of this small vegetable dibbler can be quickly corrected.

[0026] According to the above working process, it can be seen that: through the adjusting rod 6, that is, when the electric push rod 2 drives the push rod 204 and the symmetric adjusting rods 6 to move back and forth, since a fixed disk 601 is provided in the middle of the symmetric adjusting rods 6 and springs 602 are provided on both sides of the fixed disk 601, the steering of this small vegetable dibbler can be quickly corrected, increasing the safety factor, and thus increasing the practicality of this device. By slidingly connecting both ends of the adjusting plate 7 to both ends of the symmetric adjusting rods 6 respectively, one side of the adjusting rod 6 can drive the adjusting rod 6 on the other side to make the opposite movement through the adjusting plate 7. Through the baffle 702, the movement trajectory of the adjusting plate 7 is further restricted. Through the first fixing plate 3, the relative positions and movement trajectories of the symmetric adjusting rods 6 are restricted. And because both sides of the first fixing plate 3 located in the first groove 301 are designed with arc surfaces, it is convenient for the operation of the adjusting plate 7.

[0027] Furthermore, as Figure 1 shown, it is worth specifically explaining that the connecting component 9 includes symmetric fixing blocks 901. The symmetric fixing blocks 901 are both semi-circular, and convex guides 902 are fixedly connected to the upper and lower ends of the symmetric fixing blocks 901. Adjacent fixing blocks 901 are fixedly connected by bolts 903. Through the connecting component 9, that is, the symmetric fixing blocks 901, a plurality of convex guides 902 and a plurality of bolts 903, it is convenient for the front end of the adjusting rod 6 to control the steering of the fixed rod 10.

[0028] Furthermore, as shown in Figure 2 , it is worth specifically explaining that the fixing component 8 includes a bottom plate 801. The lower end of the bottom plate 801 is slidably connected to the upper end of the triangular chassis 1, and one side of the upper end of the bottom plate 801 is fixedly connected to a connecting plate 802. The upper end of the connecting plate 802 is fixedly connected to a top plate 803. The upper end of the top plate 803 is slidably connected to the vegetable dibbler main body. Through the positions of the bottom plate 801, the connecting plate 802, and the top plate 803 of the fixing component 8 and their relative connection relationships with the vegetable dibbler main body, it is convenient to control the turning of the fixing rod 10 by the front end of the symmetric adjusting rod 6, and it will not affect the position of the fixing rod 10 after turning back to the original position.

[0029] Furthermore, as shown in Figure 2 , it is worth specifically explaining that the other side of the upper end of the bottom plate 801 is slidably connected to a side plate 804. Four positioning holes 806 are provided on both the side plate 804 and the connecting plate 802. Four fixing shafts 805 can be slidably connected to the four positioning holes 806. One end of the fixing shaft 805 is fixedly connected to a connecting head 8051. The outer surface of the other end of the fixing shaft 805 is slidably connected with a gasket 8052 or threadedly connected with a nut 8053 from the inside to the outside. Limiting blocks 807 are provided in the middle of the opposite sides of the side plate 804 and the connecting plate 802. The opposite sides of the limiting blocks 807 are both semi-circular. By fixing the side plate 804 and the connecting plate 802 to each other by a plurality of fixing shafts 805, the connection and fixation of the fixing rod 10 and the vegetable dibbler main body are restricted. And through the limiting blocks 807, the fixing rod 10 can be further restricted and fixed.

[0030] In summary: The electric push rod 2 drives the push rod 204 to move back and forth, thereby driving the connecting block 604 to move back and forth, thereby driving the adjusting rod 6 on this side to move back and forth, thereby driving the steering of the small vegetable dibbler. At the same time, because the rear end of the adjusting rod 6 on this side is slidably connected to one end of the adjusting plate 7, and the other end of the adjusting plate 7 is slidably connected to the rear end of the adjusting rod 6 on the other side, and at the same time the middle position of the adjusting plate 7 is restricted, so the back-and-forth movement of the adjusting rod 6 on this side drives the adjusting rod 6 on the other side to make the opposite back-and-forth movement, that is, the small vegetable dibbler steers. When the electric push rod 2 drives the push rod 204 and the symmetric adjusting rod 6 to move back and forth, since the fixed disk 601 is provided in the middle of the symmetric adjusting rod 6 and the springs 602 are provided on both sides of the fixed disk 601, the steering of the small vegetable dibbler can be quickly restored to the right. Through the connecting assembly 9, that is, the symmetric fixing blocks 901, several convex guides 902 and several bolts 903, it is convenient to control the steering of the fixed rod 10 by the front end of the adjusting rod 6. Through the positions of the bottom plate 801, the connecting plate 802 and the top plate 803 of the fixing assembly 8 and the relative connection relationship with the main body of the vegetable dibbler, it is convenient to control the steering of the fixed rod 10 by the front end of the symmetric adjusting rod 6, and it will not affect the position of the fixed rod 10 after steering and returning to the right. The side plate 804 and the connecting plate 802 are fixed to each other by several fixed shafts 805, thereby restricting the connection and fixation of the fixed rod 10 and the main body of the vegetable dibbler, and through the limiting block 807, the fixed rod 10 can be further restricted and fixed.
