Description

Technical Field

[0001] This utility model belongs to the field of agricultural machinery and equipment technology, specifically relating to a mechanism for adjusting the spacing of seed rows by ... Background Technology

[0002] In agricultural production, sowing is a crucial step in the crop growth cycle, and its quality directly affects crop yield and quality. Traditional sowing methods rely heavily on manual labor, which is not only inefficient but also makes it difficult to ensure sowing accuracy and consistency, especially in adjusting the sowing row spacing. With the development of agricultural mechanization, sowing machinery has gradually become more widespread, but existing sowing machinery still has many shortcomings in adjusting the sowing row spacing.

[0003] While current equidistant seeders on the market can achieve equidistant seed distribution, their seeding row spacing is often fixed and cannot be flexibly adjusted according to different crop planting needs or plot conditions. For example, for some crops, a specific seeding row spacing is required to optimize light, ventilation, and nutrient absorption; and under different soil textures and terrain conditions, the seeding row spacing also needs to be adjusted accordingly to ensure the best environment for crop growth.

[0004] Furthermore, existing seeders typically require manual adjustment by stopping the machine when adjusting the seeding row spacing. This not only increases operational complexity and labor intensity but also reduces work efficiency. At the same time, manual adjustment makes it difficult to guarantee accuracy and consistency, thus affecting the seeding effect.

[0005] Therefore, there is a need for an equidistant variable spacing adjustment seeding column spacing mechanism to solve the problem that the seeding column spacing is not easy to adjust during the seeding process in the existing technology. Utility Model Content

A slider is fixedly connected to the bottom of the mounting plate, and a slide rail is slidably connected below the slider and fixedly mounted between the frames. The seed box is fixedly mounted on the upper part of the mounting plate and connected to the sowing device via the mounting plate.

[0009] It should be noted in the solution that there are two clamping plates on the synchronous belt, and the two clamping plates are respectively arranged close to the two side pulleys and symmetrically arranged vertically. The mounting plate is located inside the synchronous belt.

[0010] It is worth noting that there are five seed boxes arranged at intervals, five mounting plates connected to the five seed boxes respectively and slidably mounted between the frames via sliders, and five connecting sheet metals connected to the mounting plates respectively, which are connected to each other via hinges.

[0022] The present invention will be further described below with reference to the embodiments.

[0023] Please see Figure 1-5 This utility model provides an equidistant variable spacing adjustment seeding column spacing mechanism, including a frame 1, a seeding device 2 and a seed box 3. The seeding device 2 is mounted on the frame 1 and is equipped with a stepper motor 201. The seed box 3 is connected to the seeding device 2 through the stepper motor 201 and performs seeding through the seeding device 2. An equidistant spacing adjustment mechanism 4 is connected to the seed box 3 on the frame 1 for adjusting the seeding column spacing of the seed box 3.

[0024] The device is installed on the frame 1. During the sowing process, the stepper motor 201 runs, sowing the seeds in the seed box 3 through the sowing device 2. The specific working principle of this sowing process is a mature technology, and those skilled in the art can clearly understand its working process, so it will not be described in detail here. By setting the equal row spacing adjustment mechanism 4, the sowing row spacing can be adjusted at any time during the sowing process without manual adjustment. It can be adjusted automatically and maintain the uniformity of the sowing row spacing adjustment during the adjustment process, thereby improving the convenience of the device during use.

[0025] Further as Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, it is worth noting that the equal spacing adjustment mechanism 4 includes a worm gear reducer 401. The worm gear reducer 401 is mounted on the right rear side of the sowing device 2 via the frame 1. The output end of the worm gear reducer 401 is connected to a synchronous belt 402 via a pulley. The other end of the synchronous belt 402 is mounted on the frame 1 via another pulley. A clamping plate 405 is fixedly connected to the synchronous belt 402, and a mounting plate 406 is fixedly connected to the clamping plate 405. The top rear side of the mounting plate 406 is fixed... A connecting sheet metal 403 is fixedly installed, and a hinge rod 409 is fixedly connected to the connecting sheet metal 403. A hinge 404 is hinged to the inner side of the connecting sheet metal 403 through the hinge rod 409. A slider 407 is fixedly connected to the bottom of the mounting plate 406. A slide rail 408 is slidably connected below the slider 407 and fixedly installed between the frame 1. The seed box 3 is fixedly installed on the upper part of the mounting plate 406 and connected to the sowing device 2 through the mounting plate 406. The hinge 404 is connected in a parallelogram shape.

[0026] In use, the worm gear reducer 401 drives the pulley, causing the synchronous belt 402 to rotate. Since the two clamping plates 405 on the synchronous belt 402 are connected to the leftmost and rightmost mounting plates 406 respectively, and are located on the upper and lower sides of the synchronous belt 402, the clamping plates 405 drive the two mounting plates 406 to move towards each other under the transmission of the synchronous belt 402. The seed box 3 moves by sliding the slider 407 on the slide rail 408. Since the connecting sheet metal 403 is fixedly installed on the mounting plate 406 and connected by hinges 404, the five connecting sheet metal 403 can be adjusted equidistantly during the movement of the mounting plate 406 through the telescopic nature of the hinges 404, thereby adjusting the seed box 3 and completing the adjustment of the sowing row spacing.

[0027] Further as Figure 2 , Figure 3 and Figure 4 As shown, it is worth noting that there are two clamping plates 405 on the synchronous belt 402, which are respectively positioned close to the two pulleys on both sides and are symmetrically arranged vertically. The mounting plate 406 is located inside the synchronous belt 402. There are five seed boxes 3, which are arranged at intervals. There are five mounting plates 406, which are respectively connected to the five seed boxes 3 and are slidably mounted between the frames 1 via sliders 407. There are five connecting sheet metal 403, which are respectively connected to the mounting plates 406. The five connecting sheet metal 403 are connected to each other via hinges 404. The two clamping plates 405 are respectively connected to the leftmost mounting plate 406 and the rightmost mounting plate 406. There are two sliders 407 at the bottom of the mounting plate 406, which are symmetrically arranged front and back. There are two slide rails 408 that match the sliders 407.

[0028] This solution has the following working process: When this device is in use, it is installed on the frame 1. During the sowing process, the stepper motor 201 runs, thereby sowing the seeds in the seed box 3 through the sowing device 2. At the same time, when it is necessary to adjust the sowing row spacing between the seed boxes 3, the worm gear reducer 401 drives the pulley to rotate the synchronous belt 402. Since the two clamping plates 405 on the synchronous belt 402 are respectively connected to the leftmost and rightmost mounting plates 406, and are located on the synchronous belt 402... On the lower side, under the drive of the synchronous belt 402, the clamping plate 405 drives the two mounting plates 406 to run towards each other, and slides on the slide rail 408 through the slider 407, thereby moving the seed box 3. Since the connecting sheet metal 403 is fixedly installed on the mounting plate 406, and the connecting sheet metal 403 is connected to each other through the hinge 404, the five connecting sheet metal 403 can be adjusted at equal distances during the movement of the mounting plate 406 through the telescopic property of the hinge 404, thereby realizing the adjustment of the seed box 3 and completing the adjustment of the sowing row spacing.

[0029] In summary, by setting up the equal row spacing adjustment mechanism 4, the sowing row spacing can be adjusted conveniently at any time during the sowing process without manual adjustment. It can be adjusted automatically and maintain the uniformity of the sowing row spacing adjustment during the adjustment process, thereby improving the convenience of the device during use.
