Description

Technical Field

[0001] This utility model relates to the field of weeding technology, specifically a positioning and guiding device for weeding in sugarcane fields. Background Technology

[0002] In recent years, due to the long-term and reduced use of herbicides in sugarcane fields, a large number of herbicide-resistant weeds have emerged, leading to reduced sugarcane yield and quality. Under the trend of green agriculture development, the use of pesticides and fertilizers needs to be reduced, which has resulted in the spread of a large number of herbicide-resistant weeds in sugarcane fields. Therefore, it is urgent to develop a device that can effectively control weeds in sugarcane fields to solve the problem of the spread of a large number of noxious weeds, thereby reducing the use of pesticides and achieving the goal of weed control and increasing sugarcane yield.

[0003] Currently, most sugarcane field weeding devices on the market have fixed-length weeding blades. When dealing with sugarcane fields with varying spacing, if the blade length is greater than the sugarcane row spacing, it can easily scrape or cut sugarcane stalks or leaves during operation. This is especially problematic for seedling sugarcane, which is fragile and can directly lead to missing seedlings and reduced yield. If the blade length is less than the sugarcane row spacing, weeds will remain on both sides of the rows, creating "missed areas." These weeds compete with the sugarcane for water and nutrients, affecting sugarcane growth.

[0004] Therefore, a positioning and guiding device for weeding in sugarcane fields is proposed to address the above problems. Utility Model Content

[0005] To overcome the shortcomings of existing technologies and the inability to flexibly adapt to row spacing, this utility model proposes a positioning and guiding device for weeding in sugarcane fields.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0022] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0023] This application discloses a sugarcane field weeding positioning and guiding device, including a vehicle body 1. U-shaped frames 2 are movably installed on both sides of the vehicle body 1. An extension plate 3 is fixedly installed at the middle part of the bottom of the U-shaped frame 2. A first drive motor 4 is fixedly installed on one side of the extension plate 3. A first weeder 5 is fixedly installed on the surface of the output end of the first drive motor 4 and on the other side of the extension plate 3. Cylinders 6 are fixedly installed on both sides of the middle part of the top of the vehicle body 1. A connector 7 is fixedly installed at the end of the output end of the cylinder 6. Positioning pins 8 are fixedly installed on both sides of the bottom of the connector 7. Vertical rods 9 are fixedly installed on both sides of the top of the U-shaped frame 2. A connecting arm 10 is sleeved on the surface of the vertical rod 9. The other end of the connecting arm 10 is sleeved onto the surface of the positioning pin 8.

[0024] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 Through the structural design of U-shaped frame 2, first drive motor 4, first weeder 5, cylinder 6, connector 7, positioning pin 8, vertical rod 9, and connecting arm 10, and through the cooperation between the structures, the function of improving flexibility is realized. Thus, the output ends of the cylinders 6 on both sides can be extended to push the U-shaped frame 2 on both sides to extend outward, thereby causing the first weeder 5 on both sides of the bottom to increase the horizontal weeding range.

[0025] Both sides of the top of the U-shaped card frame 2 are fixedly installed with mounting bases 11. A crossbar 12 is movably installed inside the mounting base 11, and a card holder 13 is fixedly installed at one end of the crossbar 12.

[0026] Reference Figure 1 and Figure 3 The mounting base 11 provides space for the crossbar 12 to move freely, and the crossbar 12 can slide within the mounting base 11, which, together with the spring 16, enables the axial sliding of the wheel 14.

[0027] A rotating wheel 14 is rotatably mounted inside the card holder 13. A baffle 15 is fixedly mounted on the surface of the crossbar 12 and inside the mounting base 11. A spring 16 is sleeved on the surface of the crossbar 12 and on one side of the baffle 15.

[0028] Reference Figure 1 and Figure 3 The rotating wheel 14 facilitates rolling in close contact with the sugarcane stalk, providing guidance for the device and limiting lateral deviation to accommodate differences in plant spacing. In conjunction with the spring 16, it can effectively reduce damage to the sugarcane. The baffle 15 and spring 16 provide elastic buffering force, pushing the rotating wheel 14 to keep it close to the sugarcane stalk. When encountering changes in stalk thickness or obstacles, compression and rebound prevent damage to the sugarcane.

[0029] A connecting seat 17 is fixedly installed on one side of the bottom of the vehicle body 1. A second drive motor 18 is fixedly installed on one side of the connecting seat 17. A second weeder 19 is sleeved at the output end of the second drive motor 18 and inside the connecting seat 17.

[0030] Reference Figure 2 and Figure 3 The second drive motor 18 and the second weeder 19 facilitate the removal of weeds by generating shearing force through rotation, and can also make up for the empty space in the middle after the extension of the first weeder 5.

[0031] A handle 20 is fixedly installed on the top of the vehicle body 1 and on the side away from the connecting seat 17, and four movable wheels 21 are movably installed at the four corners of the bottom of the vehicle body 1.

[0032] Reference Figure 1 and Figure 2 The handle 20 allows the operator to push the vehicle body 1 to move and adjust the working direction, adapting to manual control needs. The moving wheels 21 help reduce the friction between the vehicle body 1 and the ground, ensuring the device moves smoothly in the field and improving operational flexibility.

[0033] Limiting holes 22 are provided on both sides of the vehicle body 1, and positioning rods 23 are fixedly installed on both sides of the inner wall of the U-shaped frame 2.

[0034] Reference Figure 3The U-shaped frame 2 can be moved and limited by the limiting hole 22 and the positioning rod 23 to improve the adjustment accuracy.

[0035] Working principle: When using this device, before operation, the cylinder 6 is activated to extend and retract according to the sugarcane row spacing, which drives the connecting piece 7 and the positioning pin 8 to move synchronously. The positioning pin 8 pulls the connecting arm 10 to rotate around the vertical rod 9, thereby driving the U-shaped frame 2 to move laterally on both sides of the vehicle body 1. At this time, the positioning rod 23 on the U-shaped frame 2 slides along the limiting hole 22 of the vehicle body 1 to limit the range of movement and ensure that the first weeders 5 on both sides are adjusted to the spacing that matches the sugarcane row spacing. During operation, the operator holds the handle 20 to push the vehicle body 1. The moving wheel 21 drives the device to move along the sugarcane rows. The rotating wheels 14 on both sides roll close to the sugarcane stalks under the elastic force of the spring 16. The first drive motor 4 drives the first weeder 5 to rotate at high speed to remove weeds on both sides of the sugarcane rows. The second drive motor 18 drives the second weeder 19 to operate and clean up the weeds missed on one side of the vehicle body 1 or between the rows.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
