Description

Technical Field

[0001] This utility model relates to the field of fixed-point planting technology for flue-cured tobacco, specifically a roller-type equidistant fixed-point planting device for flue-cured tobacco. Background Technology

[0002] Flue-cured tobacco is a type of tobacco that has been dried by roasting and is mainly used in cigarette production. The flue-cured tobacco planting roller-type equidistant fixed-point device is an auxiliary device used to improve the efficiency and standardization of flue-cured tobacco planting. It mainly solves the problems of uneven plant spacing and low efficiency when manually transplanting.

[0003] The patent document with authorization announcement number CN218417294U describes a roller-type equidistant fixed-point transplanting device for flue-cured tobacco. The described solution is simple to manufacture, lightweight, uses readily available materials, and is easy to process. Furthermore, the fixed-point distance can be flexibly adjusted according to the needs of flue-cured tobacco transplanting, facilitating field operations. Compared to previous fixed-point operation tools, it has the advantages of reducing labor and labor intensity.

[0004] The above-mentioned technology has the problem that it can only fix one row of ridges at a time, which will definitely reduce the efficiency of the single-row ridge fixing device. When planting on a large scale, more time and manpower are needed to complete the fixing work. Although the plant spacing can be guaranteed to be consistent within a single row, if the spacing between different rows is not properly controlled, it may still affect the growth of flue-cured tobacco. In addition, the above-mentioned technology also has the problem of not being able to adjust the spacing between fixing points. Different flue-cured tobacco varieties have different requirements for plant spacing. Some varieties need a larger plant spacing to ensure ventilation and light penetration, while others can be planted more densely to increase yield. A fixed plant spacing cannot meet the growth needs of different varieties and may affect the yield and quality of flue-cured tobacco. Utility Model Content

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0029] In one embodiment, such as Figures 1-4As shown, the equidistant positioning device for flue-cured tobacco planting includes: two support plates 100, an octagonal shaft 200, and a positioning assembly. The octagonal shaft 200 is rotatably connected between the two support plates 100. The positioning assembly includes two inner octagonal sleeves 301, which are slidably connected to both ends of the octagonal shaft 200. Several hollow rods 302 are provided around each of the two inner octagonal sleeves 301. A support ring 303 is provided on the end of each hollow rod 302 away from the inner octagonal sleeve 301. A positioning rod 304 is slidably connected inside each hollow rod 302. A positioning rod 304 is provided on the end of each positioning rod 304 away from the hollow rod 302. There is a fixed cone 305. The hollow rod 302 is provided with an adjustment component for adjusting the fixed rod 304. The octagonal shaft 200 is provided with a fixing component for fixing the inner octagonal sleeve 301. A moving component is provided between the two support plates 100 to drive the support plates 100 to move. The two support plates 100 are provided with a measuring component for measuring the distance between the two inner octagonal sleeves 301. By rotating the octagonal shaft 200, the inner octagonal sleeve 301 and several hollow rods 302 are further driven to rotate, thereby driving the support rod 303 and the fixed rod 304 to rotate, and then driving the fixed cone 305 to be inserted into the ridge for fixed positioning.

[0030] In one embodiment, such as Figure 2 , Figure 3 and Figure 4 As shown, the adjustment assembly includes several storage slots 401, which are respectively opened at both ends of several hollow rods 302. Each of the storage slots 401 is slidably connected to a limiting pin 402. A spring 403 is provided between each of the limiting pins 402 and the storage slots 401. A pull rod 404 is provided at one end of each of the limiting pins 402. Several limiting holes 405 adapted to the shape and specifications of the limiting pins 402 are opened on both sides of each of the fixed rods 304. By pulling the pull rod 404, the limiting pin 402 is driven to squeeze the spring 403 and move away from the limiting hole 405. Then, the fixed rod 304 is pulled to slide inside the hollow rod 302. After the adjustment is completed, the pulling force on the pull rod 404 is released. Then, under the action of the spring 403, the limiting pin 402 is driven to the inside of the limiting hole 405, thereby limiting and fixing the fixed rod 304.

[0031] In one embodiment, such as Figure 2 and Figure 3As shown, the fixing assembly includes a plurality of threaded holes 501, which are respectively opened on one side of the octagonal shaft 200. One end of each of the two inner octagonal sleeves 301 is threaded with a first locking screw 502, and the two first locking screws 502 are threadedly connected to the threaded holes 501. By rotating the first locking screw 502, it is moved away from the threaded hole 501. Then the inner octagonal sleeve 301 is slid. After it moves to a suitable position, the first locking screw 502 is rotated again to make it reach the inside of the threaded hole 501, thereby limiting and fixing the inner octagonal sleeve 301.

[0032] In one embodiment, such as Figure 1 As shown, the moving component includes a fixed plate 601, which is disposed between two support plates 100. An L-shaped block 602 is provided on the top of the fixed plate 601. A rotating rod 603 is rotatably connected to one end of the L-shaped block 602. A support frame is provided at the bottom of the rotating rod 603. A roller 604 is provided inside the support frame. The roller 604 contacts the ground and then rolls inside the support frame, thereby driving the rotating rod 603 and the L-shaped block 602 to move. Subsequently, under the action of the fixed plate 601, it drives the two support plates 100 to move.

[0033] In one embodiment, such as Figure 1 and Figure 2 As shown, the measuring component includes two scales 701, which are slidably connected to the inside of two support plates 100. The ends of the two scales 701 that are close to each other are movably abutted against the inner octagonal sleeve 301. A second locking screw 702 is threaded onto one end of each of the two support plates 100. After the inner octagonal sleeve 301 has moved, the second locking screw 702 can be rotated to move it away from the scales 701. Then the scales 701 are moved to abut against the inner octagonal sleeve 301. Then the second locking screw 702 is rotated again to abut against the scales 701 and fixed. The distance between the scales 701 and the support plate 100 is measured, thereby calculating the distance between the two inner octagonal sleeves 301.

[0034] In one embodiment, such as Figure 1 As shown, the top of the rotating rod 603 is provided with a push-pull handle, which facilitates the movement of the roller 604.

[0035] In one embodiment, such as Figure 3 and Figure 4 As shown, each of the several pull rods 404 has a pull ring at one end, which facilitates pulling the pull rod 404.

[0036] In one embodiment, such as Figure 4As shown, one end of each of the limiting pins 402 is arc-shaped, which facilitates the sliding of the fixed rod 304.

[0037] The above embodiments disclose a roller-type equidistant positioning device for flue-cured tobacco planting. According to actual needs, the spacing between the positioning points can be adjusted by pulling the pull rod 404, causing it to drive the limiting pin 402 to compress the spring 403 and move away from the limiting hole 405. Then, the positioning rod 304 is pulled, allowing it to slide inside the hollow rod 302. After adjustment, the pulling force on the pull rod 404 is released, and then, under the action of the spring 403, it drives the limiting pin 402 to the inside of the limiting hole 405, thereby positioning the points... The rod 304 is limited and fixed, and a suitable number of fixed rods 304 are retracted into the hollow rod 302, thereby changing the spacing between the fixed points. This allows the fixed rods 304 to slide inside the hollow rod 302, and the depth of the fixed points can also be adjusted. Then, the spacing is adjusted according to the required spacing for each row. The first locking screw 502 can be rotated to move it away from the threaded hole 501, and then the inner octagonal sleeve 301 is slid. After moving to the appropriate position, the first locking screw 502 is rotated again to bring it into the threaded hole 501, thereby... The inner octagonal sleeve 301 is fixed in place. Then, the second locking screw 702 is rotated to move it away from the scale 701. The scale 701 is then moved so that it rests against the inner octagonal sleeve 301. The second locking screw 702 is rotated again so that it rests against the scale 701 and is fixed in place. The distance between the scale 701 and the support plate 100 is measured, and the spacing between the two inner octagonal sleeves 301 is calculated, allowing them to be adjusted to a suitable distance. Then, the roller 604 contacts the ground and... Then it rolls inside the support frame, which in turn drives the rotating rod 603 and the L-shaped block 602 to move. Then, under the action of the fixed plate 601, it drives the two support plates 100 to move. Then, the fixed cone 305 is inserted into the ridge. As the support plate 100 moves, it drives the octagonal shaft 200 to rotate, which in turn drives the inner octagonal sleeve 301 and several hollow rods 302 to rotate, thereby driving the support rod 303 and the fixed rod 304 to rotate, thereby driving several fixed cones 305 to fix their positions.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
