Description

Technical Field

[0001] The invention relates to the technical field of agricultural machinery and tillage equipment, and in particular to a weeding and soil-raising plowshare structure and a multifunctional device for tobacco cultivation. Background Art

[0002] In the process of tobacco cultivation, weeding and soiling are the key and necessary links of field management. Weeding is to remove weeds, reduce the consumption of water and fertilizer in the soil, and prevent the breeding of pests and diseases and the spread of diseases. Timely removal of weeds is an important field management measure for the normal growth and development of tobacco leaves. Generally, weeding is done manually. A few places with better production levels use weeders and soiling machines. Soiling is to pile up soil between rows at the roots of plants, which can increase the number of roots of tobacco plants and improve the resistance of tobacco plants. Soiling can increase the yield and quality of tobacco leaves. For plants that need to overwinter, it can also increase the ground temperature to protect overwintering. Soiling thickens the loose layer of soil, isolates the cold air from the outside, and prevents the soil temperature from dropping sharply due to the influence of cold air from the outside. It relatively increases the soil temperature and protects the plants from overwintering. The soiling method depends on the sowing method. The soil is piled into trapezoidal or triangular "ridges"; generally, soiling plows and corresponding equipment are used.

[0003] However, in current production, the weeders and soil-raising machines used for weeding and soil-raising are separate equipment. Tobacco farmers need to use the weeding equipment, then switch to the soil-raising machine and leave. This is time-consuming and labor-intensive, and inefficient. In addition, the current soil-raising structure is not suitable for increasing the height and shape requirements of tobacco soil-raising. Summary of the invention

It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the present invention.

[0035] Example 1: Figure 1 , Figure 2 As shown, a weeding and soil-raising plowshare structure for tobacco cultivation includes a plow tip 3 and a plow body 4. The plow body 4 extends backward in a "V" shape and its height gradually increases from the end portion to the rear. A retaining plate 5 extending obliquely downward is respectively provided on the top edges of both sides of the plow body 4. The angle between the retaining plate 5 and the plow body 4 is between 30° and 80°, and the width gradually increases from the end portion to the tail portion. When in actual use, the plow tip 3 extending obliquely downward is inserted into the soil, and the soil is loosened and lifted up under the driving force of the forward power, and the soil is turned and pulled to the two sides of the plow tip 3, and the turned and pulled soil continues to be pushed to the two sides by the plow body 4, and is lifted up to the rear of the two sides due to the inertia, and the lifted soil is blocked after encountering the retaining plate 5 on the top of the plow body 4, and the soil moved to the end of the retaining plate 5 falls in the inclined direction of the retaining plate 5, and finally accumulates in the direction of the two sides of the retaining plate 5, achieving the soil-building effect and completing the accumulation of ridges at the same time. The retaining plate 5 plays a traction and guiding role in the moving direction of the dusty soil during the soil-building process, which can significantly affect the turning and accumulation direction of the lifted soil;

[0036] Preferably, the retaining plate 5 and the top of the plow body 4 are hingedly designed, and two adjusting cross bars 6 are respectively installed on the retaining plate 5, extending and passing through the elliptical hole 7 on the plow body 4 on the same side, and the end thereof is wired and fitted with an adjusting nut 8 for adjusting the deployment angle of the retaining plate 5. When the inclination of the retaining plate 5 needs to be adjusted, the knob adjustment nut 8 can be turned to control the telescopic length of the adjusting cross bar 6 on the plow body 4, so as to control the deployment angle of the retaining plate 5. The size of the structure can be adjusted according to actual needs, and combined with the appropriate height size of the plow body 4, the appropriate width and other size selections, and the inclination of the retaining plate 5, the required ridge width and ridge height can be quickly achieved according to actual needs. The power of weeding by the weeding disc group 2 is used to drive the movement of the entire device, so that weeding and soiling can be carried out simultaneously, which solves the problem of single equipment, improves efficiency, and saves manpower time; it achieves the effect of weeding and soiling at the same time and piling the soil onto the ridge to increase the ridge height, so that one device can simultaneously realize the effect of weeding, soiling and ridge forming multiple steps simultaneously, which significantly improves the efficiency of field management.

[0037] Embodiment 2: Based on the embodiment 1, a multifunctional weeding and soil-raising device for tobacco cultivation is obtained. Figure 3 to Figure 8As shown, it includes a plowshare 1 and a weeding disc group 2, the weeding disc group 2 is connected by a drive of an engine 9 and is installed at the front end of a bottom rod 10 located in the middle or above the weeding disc group 2, and an upwardly extending handrail 11 is installed on the bottom rod 10. The plowshare 1 includes a plow tip 3 and a plow body 4, the plow body 4 extends backward in a "V" shape and the height gradually increases from the end head to the rear, and a retaining plate 5 extending obliquely downward is respectively provided on the top edges of both sides of the plow body 4; a bottom rod 10 is installed in the middle of the plow body 4, and a horizontally placed power shaft 14 is connected to the end of the bottom rod 10 on the side of the plowshare 1, and the power shaft 1 4, the engine 9 is installed above it, and when necessary, the bottom rod 10 needs to pass through the end of the plowshare 1 or be located above it to extend to the weeding disc group 2, that is, a hole is opened on the plow body 4 at the end of the plowshare 1 to allow the bottom rod 10 to pass through, and the bottom rod 10 does not affect the plow tip 3, so that the top of the bottom rod 10 is connected to the weeding disc group 2 and is used to support and connect it; the weeding disc group 2 includes a power shaft 14, and spirally continuously wound weeding saws 15 are fixedly installed at both ends of the power shaft 14, and the engine 9 is installed between the two weeding saws 15, or above them, and the engine 9 is directly mechanically connected to the power shaft 14. Preferably, the engine 9 is directly connected to the power shaft 14 through the clutch device. Under normal circumstances, the clutch device is closed and driven to drive the power shaft 14 to rotate. The engine 9 transmits kinetic energy to the power shaft 14 through the gift box device. After the power shaft 14 rotates, it drives the weeding saw 15 to rotate. The weeding disc group 2 includes two sections of weeding saws 15 placed at both ends. Each section of the weeding saw 15 is at least wound around the power shaft 14 for at least two weeks, and a plurality of continuously distributed blade teeth 17 are provided on the edge of the disc saw, and convex ridges are alternately provided on the edge of the disc saw. The blade teeth 18 are relatively long and can be inserted more deeply into the soil. After the blade teeth 18 are rotated, the whole device can be driven forward to play a gripping role. During the rotation, the weeds are cut by the blade teeth 17 on the weeding saw 15 to achieve the weeding effect. The weeding disc group 2 is arranged in front of the two retaining plates 5, which can effectively remove the weeds in the land area that needs to be ridged, and can also play the role of a driving wheel that pulls the whole device forward, thereby driving the whole device forward, so as to achieve the effect of weeding and ridging.After the soil is turned up by the plowshare 1, it is turned and pulled toward both sides of the plow tip 3. The turned and pulled soil continues to be pushed toward both sides by the plow body 4, and is lifted up to the rear of both sides due to inertia. The lifted soil is blocked after encountering the retaining plate 5 on the top of the plow body 4, and the soil moved to the end of the retaining plate 5 falls in the inclined direction of the retaining plate 5, and finally accumulates in the direction of both sides of the retaining plate 5, achieving the soil-raising effect while completing the accumulation of ridges. The retaining plate 5 plays a traction and guidance work on the moving direction of the dusty soil during the soil-raising process, which can significantly affect the turning and accumulation direction of the lifted soil; the angle between the retaining plate 5 and the plow body 4 is between 30° and 80°, and the width gradually expands from the end head to the end tail; the retaining plate 5 and the top of the plow body 4 are hingedly designed, and two adjusting cross bars 6 are respectively installed on the retaining plate 5, extending and passing through the elliptical hole 7 on the plow body 4 on the same side, and the end thereof is wired and fitted with an adjusting nut 8 for adjusting the deployment angle of the retaining plate 5;.

[0038] During the operation of the engine 9, the operator holds the handrail 11 at the rear to control the direction, driving the weeding and soil-raising machine to move forward. The plowshare 1 is located behind the middle of the weeding disc group 2, and the plow tip 3 of the plowshare 1 extends forward and downward. The length of the weeding disc group 2 is between 20-40 cm, and the diameter of the weeding saw 15 is between 7 and 15 cm. The engine 9 is installed on the weeding disc group 2, which can increase the deadweight of the weeding disc group 2, so that it can be pressed deeper into the soil and mud, thereby improving the depth and success rate of weeding and soiling; a brake handle 20 is installed under the handrail 11, and the brake handle 20 is connected to a clutch installed in the engine 9 through a brake line. The clutch is a vehicle clutch, that is, it is separated when pressed and closed after release. The structure of the clutch is consistent with the structural principle of the vehicle clutch. A power shaft 14 is installed at one end, and the other end is connected to the engine 9 through a clutch component. When it is necessary to stop moving forward in an emergency, pressing the brake handle 20 under the handle of the handrail 11 can convert the clutch into separation, thereby disconnecting the power output. The weeding saw 15 will stop in time under the resistance of the soil and the force of the hand holding it. When turning, this method can also be used to achieve the technical effect of turning in place, further increasing the ease of use of the utility model.

[0039] Preferably, a telescopic adjustment mechanism is installed on the inner side of the plow tip, and is installed on the plow body 4 through the telescopic adjustment mechanism, so that the height can be adjusted and fixed relative to the plow body 4. Specifically, a telescopic adjustment rod 21 is extended upward on the plow tip, and a plurality of adjustment holes 22 are opened at the bottom of the telescopic adjustment rod 21, and the telescopic adjustment rod 21 is fixed to the plow body 4 through an adjusting bolt. A hinged adjustment rod 23 is installed on the bottom rod 10 between the plow body 4, and an adjustment hole 22 is opened on the hinged adjustment rod 23, and the plow body 4 is installed on the bottom rod 10 through a fixing bolt. When it is necessary to adjust the downward depth of the plow tip 3, the relative depth position of the plow tip 3 can be moved down by the telescopic adjustment rod 21 and fixed to achieve the adjustment of the height of the plow tip 3, so that it can be suitable for fields, ground, and soil with different softness and hardness, and can be adaptively adjusted according to the required depth of soiling to achieve the desired purpose; when it is necessary to adjust the soiling width range as required, the length of the hinged adjustment rod 23 can be adjusted to achieve the angle between the expanded plow body 4 to control the width value of its opening, so that the soiling width is adjusted. By controlling the size of the invention and rationally designing the structure, the overall weight can be controlled within 60-80kg, and the power requirement of the engine can be halved to 80cc, which not only improves work efficiency and reduces labor costs, but also achieves lightweight design through the control of weight and engine horsepower, and has more flexibility, better controllability and safety.

[0040] Example 3: Figure 9-11As shown, the power shaft 14 is a segmented structure, the middle part is a round shaft connected to the engine 9, the two ends are four-sided square tubes or hexagonal tubes 24 and the ends are wired, the central axis part of the weeding saw 15 is a four-sided sleeve or hexagonal sleeve 25 that is compatible with the size and length of the four-sided square tube or hexagonal tube 24, and the end sleeve 27 is screwed and installed on the wired end; when not in the weeding and soil-raising state, the weeding saw 15 is replaced with a traveling wheel 26, and the traveling wheel 26 is mounted on the power shaft 14 for drive connection. Such a structure can meet the needs of replacing the weeding saw 15 and meet the convenience and safety of walking in a non-operating state on flat ground. Specifically, in actual use, the two driving wheels 26 can be mounted on the two ends of the power shaft 14 with four-sided square tubes at both ends through the four-sided sleeve structure of the central axis at the tobacco farmer's home, and tightened through the end sleeve 27, that is, the front end is replaced with the two driving wheels 26 structure. When it is necessary to set out for the tobacco field, it can be manually pushed to travel on flat ground or general land, or it can be started and driven by the driving wheels 26. In this way, the device can be conveniently and safely brought to the field where weeding and soiling are required, or after completing the weeding and soiling operation, it can be taken home or to the warehouse for use. After arriving at the area where weeding and soiling are required, the driving wheels 26 are removed, and the two end covers 27 with four-sided sleeves are replaced. After putting on, the end covers 27 are tightened. When the power shaft 14 rotates under the drive of the engine, the rotational power is transmitted to the weeding saws 15 at both ends through the adaptable contact between the four-sided tube and the four-sided sleeve, driving them to rotate, so that weeding and soiling can be carried out. Such a structural design can make the device more flexible and can switch between the weeding and driving states according to actual needs, thereby improving the mobility of the device.

[0041] It should be understood that the above specific embodiments of the present invention are only used to illustrate or explain the principles of the present invention, and do not constitute a limitation of the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and scope of the present invention should be included in the protection scope of the present invention. In addition, the appended claims of the present invention are intended to cover all changes and modifications that fall within the scope and boundaries of the appended claims, or the equivalent forms of such scope and boundaries.
