Description

Technical Field

[0001] This utility model relates to the technical field of agricultural production plowing equipment, specifically a spacing adjustment structure for plowing equipment. Background Technology

[0002] In agricultural production, plowing equipment is an indispensable tillage machine. It uses multiple plows to simultaneously turn over the land to improve work efficiency. In traditional multi-plow equipment, the spacing between each plow is usually fixed or manually adjustable. The manual adjustment process is cumbersome, time-consuming, and labor-intensive, and cannot achieve flexible adjustment. It is difficult to adapt to the diverse needs of different crops or agronomic practices for row spacing. The adjusted plows lack an effective locking mechanism. In complex field operations, the plows are prone to displacement due to force, resulting in changes in row spacing and poor stability. Moreover, the traditional adjustment process relies on manual labor, which cannot match the trend of modern agricultural machinery automation and intelligence, thus restricting further improvement in work efficiency. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a spacing adjustment structure for plowing equipment to prevent the spacing between plow bodies from shifting due to force during plowing.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: a spacing adjustment structure for plowing equipment, including a crossbeam, a connecting structure on the front side of the crossbeam, a spacing scale on the right side of the top of the crossbeam, and a driving and fixing structure inside the crossbeam;

[0005] The drive fixing structure includes: a drive motor, a helical gear, a first lead screw, a second lead screw, a first slider, a second slider, a fixed plow column, two movable plow columns, and three plow bodies;

The first lead screw is movably embedded inside the right end of the crossbeam via a bearing, and one end is connected to the helical gear. The second lead screw is movably embedded inside the left end of the crossbeam, and one end is connected to the helical gear. The first slider is movably fitted onto the left end of the first lead screw, and the second slider is movably fitted onto the right end of the second lead screw. The fixed plowshare is fixedly installed at the bottom end of the crossbeam. The two movable plowshares are respectively connected to the first slider and the second slider.

When adjusting the spacing, the parameters of the spacing scale can be observed to determine the spacing position. The drive motor is a servo motor.

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] Example 1

[0021] like Figure 1-3 As shown, a spacing adjustment structure for a plowing device includes a crossbeam 1, a connecting structure on the front side of the crossbeam 1, a spacing scale 2 on the right side of the top of the crossbeam 1, and a drive fixing structure inside the crossbeam 1.

[0022] The drive and fixed structure includes: a drive motor 3, a helical gear 4, a first lead screw 5, a second lead screw 6, a first slider 7, a second slider 8, a fixed plow column 9, two movable plow columns 10, and three plow bodies 11.

[0023] The drive motor 3 is fixedly installed at the top of the crossbeam 1, and the drive end is movably embedded inside the crossbeam 1. The helical gear 4 is connected to the drive end of the drive motor 3. The first lead screw 5 is movably embedded inside the right end of the crossbeam 1 through a bearing, and one end is connected to the helical gear 4. The second lead screw 6 is movably embedded inside the left end of the crossbeam 1, and one end is connected to the helical gear 4. The first slider 7 is movably fitted onto the left end of the first lead screw 5, and the second slider 8 is movably fitted onto the right end of the second lead screw 6. The fixed plow column 9 is fixedly installed at the bottom end of the crossbeam 1. The two movable plow columns 10 are respectively connected to the first slider 7 and the second slider 8. The three plow bodies 11 are respectively installed at the bottom ends of the fixed plow column 9 and the two movable plow columns 10.

[0024] In use, the operator first connects the device to the required power supply or controller. The drive motor 3 operates, driving the helical gear 4 to rotate. The helical gear 4 drives the first lead screw 5 and the second lead screw 6 to rotate. When the lead screws rotate, the first slider 7 and the second slider 8 move, causing the lower plow column to adjust the spacing. At this time, the spacing scale 2 can be observed to determine the spacing adjustment distance, thereby achieving the spacing between the plow bodies 11, which promotes production. The bottom end of the crossbeam 1 is equipped with a fixed plow column 9, which remains fixed and cannot be adjusted in terms of spacing. The spacing is adjusted by moving the plow column 10. The fixed plow column 9 and the moving plow column 10 form a group, and each has a plow body 11 below it. Multiple plow bodies 11 work at the same time, increasing the working area and allowing multiple plowing operations to be performed at once.

[0025] In the specific implementation process, the connecting structure includes: plow frame 12, suspension frame 13 and limiting structure;

[0026] The plow frame 12 is installed on the front side of the crossbeam 1, the suspension frame 13 is fixedly installed on the top of the plow frame 12, and the limiting structure is installed on the bottom of the plow frame 12.

[0027] In use, the plow frame 12 is fixedly installed on the front side of the crossbeam 1, and the suspension frame 13 is fixedly installed on the top of the plow frame 12. Through the plow frame 12 and the suspension frame 13, the crossbeam 1 can be supported, and the crossbeam 1 and the drive fixed structure can be installed stably and conveniently.

[0028] In the specific implementation process, the limiting structure includes: two wheel columns 14 and two depth limiting wheels 15;

[0029] Two wheel posts 14 are respectively installed on both sides of the bottom end of the plow frame 12, and two depth limiting wheels 15 are respectively installed on the bottom ends of the two wheel posts 14 via rotating shafts.

[0030] When in use, the wheel column 14 and the depth limiting wheel 15 provide support and limit the plow body 11 during operation, preventing the plow body 11 from going too deep in the longitudinal direction during land operation, which would lead to excessive plowing and damage to the soil. At the same time, it also prevents the plow body 11 from getting stuck in the soil due to excessive depth, which would cause excessive resistance and make it difficult to work.

[0031] In the specific implementation process, the first lead screw 5 has a positive thread, and the second lead screw 6 has a negative thread.

[0032] In use, the first slider 7 and the second slider 8 at the first lead screw 5 and the second lead screw 6 move in opposite directions under the driving action of the drive motor 3 through the forward thread of the first lead screw 5 and the reverse thread of the second lead screw 6, thereby realizing the spacing adjustment.

[0033] In the specific implementation process, a lubrication port and a lubrication cover are provided on the left side of the top of the crossbeam 1.

[0034] During use, the first lead screw 5 and the second lead screw 6 require regular maintenance. Lubricating oil can be added to the first lead screw 5 and the second lead screw 6 through the lubrication port at the top of the crossbeam 1 to perform maintenance. When maintenance is completed, the lubrication port can be sealed with a lubrication cover to prevent dust and impurities from entering and damaging the equipment.

[0035] In the specific implementation process, reinforcing ribs are provided at the connection between the crossbeam 1 and the plow frame 12, as well as between the plow frame 12 and the suspension frame 13.

[0036] In use, the crossbeam 1 is connected and installed with the plow frame 12, and the plow frame 12 is connected and installed with the suspension frame 13. The reinforcing ribs can be set to ensure the structural stability and firm installation, and provide better support for the device.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
