Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary devices for flue-cured tobacco planting, specifically to a device for shaping tobacco ridges in tobacco fields. Background Technology

[0002] During the tobacco planting preparation stage, ridging is an important technical measure in tobacco cultivation. Ridge shaping is a crucial agronomic step to ensure the normal growth of tobacco plants. Conventional methods mostly use traditional ridge shaping tools to shape the ridges for planting tobacco. However, due to their unreasonable structural design and manufacturing, the ridges produced are too small and too short, making it difficult to achieve the required ridge height of 20cm. These small ridges affect the root development and growth of tobacco plants. On the other hand, the operation of traditional shaping tools is also relatively difficult, resulting in low labor efficiency for tobacco farmers and consequently, generally high labor costs. This is the main problem currently faced. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a tobacco ridge shaping device to solve the problems of traditional ridge shaping devices forming ridges that are short, incomplete, laborious to operate, inefficient, and difficult to achieve ideal agronomic requirements.

[0004] To solve the above problems, this utility model provides the following technical solution:

[0005] A tobacco ridge shaping device includes a crossbar; a connecting component for connecting to a power source is installed at the rearward position of the middle of the crossbar; positioning sleeves are installed at both ends of the crossbar facing the front; shaping plate assemblies are provided on the lower side of each of the two positioning sleeves; the shaping plate assemblies include a first plate; a second plate and a third plate are respectively inclinedly arranged on the front and rear sides of the first plate; the distance between the two shaping plate assemblies gradually narrows from the front to the rear.

[0006] Preferably, the crossbar is a straight hexagonal steel pipe; the connecting assembly includes a connecting rod disposed on the rear end face of the middle part of the crossbar; a vertical plate perpendicular to the connecting rod is disposed on the other end of the connecting rod; a connecting pipe is disposed on the other end face of the vertical plate; the axis of the connecting pipe is arranged vertically.

[0007] Preferably, the installation position of the positioning sleeve on the crossbar is adjustable; the positioning sleeve is a hollow tube structure, and its inner cavity is connected to the crossbar through a hole-shaft fit; a boss is provided on the tube wall of the positioning sleeve; a threaded hole is opened on the boss; the lower end of the threaded hole communicates with the inner cavity of the positioning sleeve; the positioning sleeve is detachably locked to the crossbar at the threaded hole by a bolt assembly.

[0008] Furthermore, each positioning sleeve has two protrusions, and the two protrusions are arranged symmetrically.

[0009] Preferably, at least two fixing rods are provided on the lower side of the positioning sleeve; the fixing rods are located on the same plane, and the middle part of one end face of the first plate is connected to the tail end of the fixing rod.

[0010] Preferably, the first plate is a pentagonal plate component, which is similar to the shape formed by cutting off one corner of the upper side of a quadrilateral plate, and its top edge is connected to the positioning sleeve; the second plate is a rectangular plate component, which is connected to the right-angled side of the first plate perpendicular to the top edge; the third plate is a triangular plate component, one side of which is connected to the hypotenuse of the first plate.

[0011] Furthermore, the first plate, the second plate, and the third plate are integral components made of steel plates; one side of the third plate is connected to a positioning sleeve.

[0012] The beneficial effects of this utility model are reflected in the following aspects:

[0013] 1. This utility model, through the cooperation of two sets of shaping plates, enables the device to continuously and stably gather the soil towards the center line of the ridge and lift it upward during movement; the first plate is used to shape the full middle of the ridge, and the third plate further lifts and shapes the top layer of soil, thereby ensuring that the height of the ridge is stably up to the agronomic requirement of more than 25cm, and the ridge is round, full and straight, providing a superior growth space for the tobacco roots.

[0014] 2. The combination of hexagonal steel pipe crossbars and adjustable positioning sleeves ensures the rigidity and stability of the overall frame; the added shaping rods strengthen the support of the shaping plate group, prevent deformation due to soil resistance during operation, and ensure the uniformity and consistency of the shaping effect.

[0015] 3. It can be quickly connected to the existing power sources of tobacco farmers, such as rotary tillers, through the connecting pipe, without the need to purchase special power equipment, which greatly reduces the user's operating costs and technical threshold;

[0016] 4. The position of the positioning sleeve on the crossbar can be flexibly adjusted and locked by bolts, thereby changing the spacing between the two sets of shaping plates, so that the device can adapt to the shaping needs of different row spacing or ridge width, and improve the versatility of the equipment.

[0017] 5. It avoids the need for later shaping of the ridges, significantly improving work efficiency and achieving the core objective of reducing labor and costs. Attached Figure Description

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0022] Example:

[0023] Reference Figure 1 This embodiment provides a tobacco ridge shaping device; it includes a crossbar 1; a connecting component 2 for connecting to a power source is installed at the rearward position of the middle of the crossbar 1; positioning sleeves 3 are installed at both ends of the crossbar 1 facing the front; shaping plate groups are provided on the lower side of both positioning sleeves 3; the shaping plate group includes a first plate 4; a second plate 5 and a third plate 6 are respectively inclinedly arranged on the front and rear sides of the first plate 4; the distance between the two shaping plate groups gradually narrows from the front to the rear. The layout of being wider at the front and narrower at the rear forms a natural channel for guiding and compressing. When the device is pulled forward, loose soil is introduced from both sides and gradually gathers, compresses and lifts towards the center within this channel, which is a key structural feature for forming tall and full ridges.

[0024] The crossbar 1 is a straight hexagonal steel pipe; the connecting assembly 2 includes a connecting rod 21 set on the rear end face of the middle part of the crossbar 1; a vertical plate 22 perpendicular to the connecting rod 21 is set on the other end of the connecting rod 21; a connecting pipe 23 is set on the other end face of the vertical plate 22; the axis of the connecting pipe 23 is arranged vertically. In this embodiment, the crossbar is 61cm long and 3.5cm in diameter; the connecting rod 21 is also a hexagonal steel pipe, 6.5cm long and 3.5cm in diameter; the vertical plate is an iron block 8.5cm long, 4.5cm wide and 0.8cm thick; the connecting pipe 23 is a circular steel pipe 5.7cm long, 2.9cm outer diameter and 2.0cm inner diameter; the connecting pipe is used to connect the rotary tillage machinery used by conventional tobacco farmers. As the core load-bearing and connecting skeleton of the entire device, the crossbar's hexagonal cross-section can effectively prevent the positioning sleeve from rotating on it, ensuring the stability of the shaping angle. The connecting components can transmit the traction force from the power source to the entire device, and the vertical connecting pipes are easy to adapt to various standard agricultural machinery suspension points.

[0025] The mounting position of the positioning sleeve 3 on the crossbar 1 is adjustable. The positioning sleeve 3 is a hollow tube structure, and its inner cavity is connected to the crossbar 1 through a hole-shaft fit. A boss is provided on the tube wall of the positioning sleeve 3. A threaded hole is opened on the boss. The lower end of the threaded hole communicates with the inner cavity of the positioning sleeve 3. The positioning sleeve 3 is detachably locked to the crossbar 1 at the threaded hole by a bolt assembly. In this embodiment, the positioning sleeve also corresponds to a hexagonal steel tube component with a length of 8.5cm, an inner diameter of 3.55cm, and an outer diameter of 4.55cm. The adjustable positioning sleeve design allows users to flexibly adjust the initial width between the two shaping plate groups according to the actual planting row spacing required, greatly enhancing the applicability and practicality of the device.

[0026] Each positioning sleeve 3 has two bosses, which are symmetrically arranged. The symmetrical double-bolt locking structure provides a more balanced and powerful locking force, preventing displacement due to vibration and resistance during the shaping process and ensuring the consistency of operating parameters.

[0027] At least two fixing rods 7 are also provided on the lower side of the positioning sleeve 3; the fixing rods 7 are located on the same plane, and the middle of one end face of the first plate 4 is connected to the tail end of the fixing rod 7. The plane where the fixing rod is located is perpendicular to the horizontal plane; in this embodiment, the fixing rod 7 is a threaded steel bar with a diameter of 1.2cm, and there are a total of 3 fixing rods 7, with lengths of 15cm, 16cm and 23cm respectively; the three fixing rods are arranged in a claw shape, and their upper ends are connected to the positioning sleeve 3. The fixing rods form a sturdy support frame, which firmly supports the shaping plate assembly in the predetermined shape and position; it bears most of the force of the soil on the shaping plate and can prevent the thin plate-shaped shaping plate from bending under force.

[0028] The first plate 4 is a pentagonal plate component, similar in shape to a quadrilateral plate with one corner cut off from the top. Its top edge is connected to the positioning sleeve 3. The second plate 5 is a rectangular plate component, connected to the first plate 4 along a right-angled side perpendicular to its top edge. The third plate 6 is a triangular plate component, with one side connected to the hypotenuse of the first plate 4. The angles formed by the first plate 4 with the second plate 5 and the third plate 6 are all 160°. This obtuse 160° angle design makes the soil lifting process smoother, avoiding soil settling or blockage that might occur at steep angles.

[0029] The first plate 4, the second plate 5, and the third plate 6 are connected by a single component made of steel plate; one side of the third plate 6 is connected to the positioning sleeve 3. The lengths of the five sides of the first plate 4 are 25cm, 9cm, 29cm, 7cm, and 26cm, respectively. The second plate 5 is a square plate with a length of 25cm and a width of 10cm, which is used for the first shaping of the bottom layer of soil in the tobacco ridge to ensure that the row spacing meets the requirements; the first plate is used for the second shaping of the middle layer of soil in the ridge to ensure that the tobacco ridge is round and full. The three sides of the third plate 6 have lengths of 31cm, 37.5cm, and 22.5cm, respectively. Its function is to further raise the middle layer of soil in the ridge, so that the top layer of soil in the ridge can reach a height of more than 25cm, and to flatten the top layer of the ridge to facilitate mulching and transplanting of tobacco seedlings. The integrated component can work stably under harsh soil conditions, has a long service life, and is easy to maintain.

[0030] This device can be installed with ordinary rotary tillers. By shaping the soil, it ensures that the ridges in tobacco fields are full and the ridge height reaches the technical requirement of more than 25cm. At the same time, this tobacco field ridge shaping device retains the use of the original rotary tillage machinery and power source of tobacco farmers, without adding extra costs and production inputs for tobacco farmers. The new device is simple to manufacture, and its cost, weight, and volume are not much different from conventional ridge shaping devices, making it easy for tobacco farmers to accept and use. It achieves the effect of reducing labor and costs for tobacco farmers planting flue-cured tobacco.
