For those of ordinary skill in the art, the specific meaning of the above terms in the present application can be understood through specific circumstances.

[0030] In the embodiments of this application, the terms "exemplary" or "for example" are used to indicate that something is an example, illustration, or description. Any embodiment or design that is described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design. Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0031] This embodiment provides a weeding and soil-loosening device for an experimental field, see reference. Figures 1-5 As shown, the device includes a support platform 1, with support frames 2 on both sides of the support platform 1. A traveling wheel 21 is installed at the bottom of each support frame 2. A contact head 3 is located below the support platform 1. The contact head 3 is pyramidal in shape and is connected to the support platform 1 via a first connecting part 31. A medicine chamber 4 is connected to one side of the first connecting part 31. A mounting groove 32 is provided on the rear end face of the contact head 3. A spray pipe 42 is installed in the mounting groove 32 and is connected to the medicine chamber 4 via a connecting pipe 41. A rotating shaft assembly 5 is located on the rear side of the mounting groove 32 and is connected to the support platform 1 via a second connecting part 51.

[0032] In the above embodiment, support frames 2 are provided on both sides of the support platform 1, and the bottom of the support frame 2 is equipped with a traveling wheel 21, which can be used to drive the device to move on the ground, improving the mobility of the device. A contact head 3 is provided below the support platform 1, and the contact head 3 is arranged in a pyramidal shape, such as... Figure 1As shown, the front end of the contact head 3 is a pyramidal tip, and the upper surface of the contact head 3 is an inclined plane. In use, the tip of the contact head 3 is embedded in the surface soil, pushing the support platform 1 to move the contact head 3 forward. During this movement, the tip of the contact head 3 travels within the surface soil layer. Because the upper surface of the contact head 3 is inclined, the tip of the contact head 3 pries up the soil layer, and the lifted soil layer flips up along the inclined plane of the upper part of the contact head 3, thus loosening the surface soil. Furthermore, the contact head 3 is connected to the support platform 1 via the first connecting part 31. The support platform 1 can move long distances on the ground via the traveling wheels 21 at the bottom of the support frame 2, allowing the contact head 3 to travel long distances within the soil surface. Compared to manually turning the soil with handheld agricultural implements, this method improves the efficiency of loosening the soil in the experimental field. The device components of this application are easy to assemble and can be driven by human power or a simple electric motor traction device, making it more flexible than large agricultural machinery. In addition, a pesticide chamber 4 is installed on one side of the first connecting part 31 for filling with herbicides. A mounting groove 32 is provided on the rear end face of the contact head 3, and a spraying pipe 42 is provided in the mounting groove 32. The spraying pipe 42 has multiple discharge holes 100. The spraying pipe 42 is connected to the pesticide chamber 4 through a connecting pipe 41. During the process of the front end of the contact head 3 moving and loosening the soil in the soil layer, the spraying pipe 42 at the rear end of the contact head 3 sprays out the herbicide, so that the pesticide can fully contact the surface soil, which is beneficial to improving the mixing efficiency of the pesticide and the surface soil. Furthermore, a rotating shaft assembly 5 is provided on the rear side of the installation groove 32. The rotating shaft assembly 5 includes a rotating shaft and a stirring rod disposed on the side wall of the rotating shaft. The rotating shaft of the rotating shaft assembly 5 rotates, causing the stirring rod on the side wall of the rotating shaft to agitate the soil turned up by the contact head 3. On the one hand, this makes the soil looser, and on the other hand, the agitation of the soil makes the herbicide mix more thoroughly with the soil, which is beneficial to more fully exert the efficacy of the herbicide to inhibit the germination of weed seeds.

[0033] In one embodiment of this application, see reference Figure 5 As shown, the first connecting part 31 includes a connecting rod 311, and an insert rod 312 is provided at the upper end of the connecting rod 311. The insert rod 312 passes through the support platform 1 and is inserted into the sleeve 313 on the end face of the support platform 1. The sleeve 313 has a threaded hole 314 on its side wall, and a fastening bolt 315 is fitted in the threaded hole 314.

[0034] In the above embodiment, the sleeve 313 is used to limit the insertion rod 312, thereby restricting the movement of the connecting rod 311 and the contact head 3 along the vertical direction set by the sleeve 313. The movement of the contact head 3 in the vertical direction can adjust the travel depth of the contact head 3 in the surface soil to adapt to ground with height differences for loosening. If there is a protrusion in the ground, the contact head 3 can be moved upward to prevent the contact head 3 from inserting too deeply into the ground and increasing the travel resistance. If there is a pit in the ground, the height of the contact head 3 can be adjusted downward to prevent the contact head 3 from not contacting the soil, which is beneficial to improving the adaptability of the device. Furthermore, by screwing in the fastening bolt 315 in the threaded hole 314, the fastening bolt 315 abuts against the insertion rod 312, increasing the friction between the sleeve 313 and the insertion rod 312 for positioning the insertion rod 312, and thus fixing the contact head 3. Similarly, unscrewing the fixing bolt can be used to adjust the position of the contact head 3.

[0035] In one embodiment of this application, see [reference] Figure 2 As shown, the second connecting part 51 includes an electric telescopic rod 511. The telescopic end face of the electric telescopic rod 511 is connected to a mounting plate 512. A first motor 513 is provided on one side of the mounting plate 512. The first motor 513 is connected to the rotating shaft assembly 5 in a transmission connection.

[0036] In the above embodiments, the extension and retraction of the electric telescopic rod 511 are used to adjust the distance between the rotating shaft assembly 5 and the ground, which is beneficial to improving the adaptability and stability of the rotating shaft assembly 5. The first motor 513 is used to drive the rotating shaft assembly 5 (i.e. the rotating shaft of the rotating shaft assembly) to operate, so as to move the soil and improve the uniformity of the mixing of the agent and the soil.

[0037] In one embodiment of this application, see reference Figure 3 As shown, a sealing cover 43 is provided on the upper part of the medicine chamber 4, and a one-way valve 431 is provided on the sealing cover 43.

[0038] In the above embodiment, the one-way valve 431 is used to connect to the air pipe or air pump and to inject pressurized air into the agent chamber 4, thereby increasing the pressure in the agent chamber 4 and pushing the herbicide through the connecting pipe 41 into the spray pipe 42 and then spraying it out from the outlet 100, preventing the outlet 100 from becoming blocked and improving the smoothness of the agent spraying.

[0039] In one embodiment of this application, see reference Figure 3 As shown, a first control valve 411 is installed on the connecting pipe 41.

[0040] In the above embodiment, the first control valve 411 is used to control the dispensing of medicine through the connecting pipe 41 to prevent the medicine in the medicine chamber 4 from flowing out through the connecting pipe 41 when the device is not working, thus causing waste of medicine.

[0041] In one embodiment of this application, see reference Figure 4 As shown, the front end face of the connecting rod 311 is provided with a tip 3111.

[0042] In the above embodiment, during the process of the contact head 3 traveling in the soil layer, the front end face of the connecting rod 311 will come into contact with the soil. The tip 3111 can reduce the contact area between the end face of the connecting rod 311 and the soil, which is beneficial to reduce the travel resistance of the connecting rod 311 driving the contact head 3 in the soil layer.

[0043] In one embodiment of this application, see reference Figure 1 As shown, a handle frame 11 is connected to the side of the support platform 1.

[0044] In the above embodiment, the handle frame 11 is equipped with a gripping point on the support platform 1, which makes it easier for one or more people to push and walk the device.

[0045] In actual use of this application: Support frames 2 are provided on both sides of the support platform 1, and the bottom of the support frame 2 is equipped with a walking wheel 21, which can be used to drive the device to move on the ground. When in use, the tip of the contact head 3 is stuck into the surface soil. A manual or electric traction device can be used to drive the support platform 1 and thus drive the contact head 3 to move towards the tip of the contact head 3. During the movement of the contact head 3 in the soil layer, the tip of the contact head 3 pries up the soil layer. The raised soil layer is turned up along the slope of the upper part of the contact head 3, making the surface soil loose. A chemical chamber 4 is installed on one side of the first connecting part 31 for filling with herbicides. The rear end face of the contact head 3 is provided with The installation groove 32 is equipped with a spray pipe 42, which has multiple discharge holes 100. The spray pipe 42 is connected to the pesticide chamber 4 via a connecting pipe 41. As the front end of the contact head 3 moves through the soil to loosen it, the spray pipe 42 at the rear end of the contact head 3 sprays out the herbicide, ensuring that the herbicide comes into full contact with the surface soil. A rotating shaft assembly 5 is provided on the rear side of the installation groove 32. The rotating shaft of the rotating shaft assembly 5 drives the stirring rod on the side wall of the rotating shaft to agitate the soil turned up by the contact head 3, making the herbicide mix more thoroughly with the soil. This helps to fully exert the herbicide's efficacy in inhibiting the germination of weed seeds.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
