Description

Technical Field

[0001] This utility model relates to the field of weeding machine technology, specifically a weeding machine for planting Chinese medicinal herbs. Background Technology

[0002] Chinese medicinal herb cultivation is a comprehensive industry that combines traditional agricultural techniques with modern technology. It involves producing Chinese medicinal herbs in specific geographical environments by using appropriate agricultural techniques based on their unique growth environment and requirements.

[0003] Currently, weeding operations in medicinal herb fields typically use weeding machines. The bottom of the weeding machine's wheels is generally parallel to or slightly lower than the cutting blades. Users remove weeds by pressing down on the cutting blades. This design makes it easier for the cutting blades to penetrate the soil and remove weed roots. However, when pushing the weeding machine, its wheels slide on the ground, and the cutting blades also slide along with it. If the ground is a hard material such as cement, this may cause the cutting blades to break (to avoid this, currently the weeding machine usually needs to be tilted significantly, which increases the difficulty of operation). Therefore, a new type of weeding machine for medicinal herb cultivation is needed to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that the cutting blades of a lawnmower may be damaged by rubbing against the ground when moving on hard materials such as cement. This utility model provides a lawnmower.

[0005] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0006] A weeding machine for planting Chinese medicinal herbs includes: a mounting frame, on the inner wall of which a cutting blade assembly is rotatably mounted; and a drive unit for driving the cutting blade assembly to rotate.

[0007] The mounting bracket has rollers slidably inserted into its inner wall and also includes a lifting unit. The lifting unit is used to rotate the rollers onto the inner wall of the mounting bracket and control the spatial height of the rollers.

[0008] Furthermore, the mounting frame includes a main frame, a push rod is fixedly mounted on the surface of the main frame, the cutting blade assembly is rotatably mounted on the inner wall of the main frame, and the roller is slidably inserted into the inner wall of the main frame.

[0009] Furthermore, the cutting blade assembly includes a rotating wheel rotatably mounted on the inner wall of the main frame, the surface of the rotating wheel being provided with a plurality of cutting blades, and also includes a mounting unit for mounting the plurality of cutting blades onto the surface of the rotating wheel.

[0010] Furthermore, the mounting unit includes several mounting protrusions, each disposed on the surface of the rotating wheel. Mounting rods are fixedly mounted on the surfaces of the mounting protrusions. Several cutting blades are slidably sleeved on the surfaces of the mounting rods. Abutment nuts are threaded onto the surfaces of the mounting rods.

[0011] Furthermore, the drive unit includes two drive wheels, one end of which is fixedly mounted to one end of the rotating wheel, and a drive motor is fixedly mounted on the surface of the main frame. The other drive wheel is rotatably mounted on the output end of the drive motor. The drive motor is electrically connected to a controller fixedly mounted on the surface of the push rod, and the two drive wheels are slidably sleeved with the same transmission belt.

[0012] Furthermore, the lifting unit includes two mounting slots respectively opened on both sides of the main frame. Both ends of the roller are rotatably sleeved with sliders. The surfaces of the two sliders are slidably inserted into the inner walls of the two mounting slots. A drive threaded rod is threaded into the inner wall of one of the mounting slots. One end of the drive threaded rod is rotatably inserted into the surface of one of the sliders. A guide rod is slidably inserted into the inner wall of the other mounting slot. One end of the guide rod is fixedly installed on the surface of the other slider.

[0013] Furthermore, a protective shell is fixedly installed on the surface of the main frame.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. In this utility model, a cutting blade assembly is rotatably installed on the inner wall of the mounting frame. During subsequent use, the user can push the mounting frame, and the cutting blade assembly is driven to rotate through the drive unit to achieve the purpose of weeding. At the same time, when it is necessary to move this device on a relatively hard surface such as a cement floor, the height of the rollers can be controlled by the lifting unit, so that when the user pushes the mounting frame, the rollers slide in contact with the ground. Since the bottom of the cutting blade assembly is relatively higher than the bottom of the rollers, it will not touch the ground, thus avoiding damage to the surface of the cutting blade assembly.

[0016] 2. In this utility model, by disassembling the cutting blade assembly into a rotating wheel and several cutting blade bodies, the user can first place several cutting blade bodies onto the surface of several mounting rods, and then thread contact nuts onto the surface of several mounting rods to install several cutting blade bodies on several mounting protrusions. Therefore, the user can also replace the cutting blade bodies in the above way to improve the overall service life of the device. Attached Figure Description

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0024] This embodiment provides a weeding machine for planting Chinese medicinal herbs, mainly to solve the problem that the cutting blades may scrape and break when the weeding machine moves on hard materials such as cement. The following technical solution is provided, which will be discussed in conjunction with... Figures 1-5 Please provide a detailed explanation:

[0025] A weeding machine for planting Chinese medicinal herbs includes: a mounting frame 1 with a cutting component rotatably mounted on its inner wall; rollers 4 are slidably connected to the inner wall of the mounting frame 1. During operation, the user pushes the mounting frame 1 with rollers 4 to slide on the ground, while a drive unit 3 activates the cutting component to rotate, thus achieving the weeding function. To prevent damage to the cutting component during movement on a concrete surface when weeding is not required, the device is equipped with a lifting unit 5 to adjust the height of the rollers 4, ensuring that only the rollers 4 contact the ground during movement, while the cutting component maintains a safe distance. The main... The components are: a main frame 11 with push rods 12 fixedly mounted on its surface; a cutting assembly installed inside the main frame 11; and the entire device can be moved forward by pushing the push rods 12. The drive unit 3 mainly consists of a drive motor 32 fixedly mounted on the surface of the main frame 11, and a drive wheel 31 fixedly mounted on one end of the rotating wheel 21. A drive wheel 31 is also rotatably mounted on the surface of the main frame 11. In use, the user controls the output of the drive motor 32 to rotate via a controller 33 fixedly mounted on the surface of the push rods 12, which in turn drives one of the drive wheels 31 to rotate. Because there are two drive wheels... The same transmission belt 34 is slidably sleeved on the surface of wheel 31, so when one drive wheel 31 rotates, both drive wheels 31 will rotate simultaneously, further driving the rotating wheel 21. The main components of the cutting blade assembly 2 are: a rotating wheel 21 rotatably mounted on the inner wall of the main frame 11, and several cutting blades 22 are provided on the surface of the rotating wheel 21. In use, the user can install several cutting blades 22 on the surface of the rotating wheel 21 through the mounting unit 23. The main components of the lifting unit 5 are: two mounting slots 51 respectively opened on both sides of the main frame 11. Both ends of the roller 4 are rotatably sleeved with sliders 52, and the surfaces of the two sliders 52 are slidably inserted into the inner walls of the two mounting slots 51 respectively. In use, the user rotates the drive thread rod 53 threaded into the inner wall of one of the mounting slots 51, which drives the slider 52 rotatably sleeved at one end of the drive thread rod 53 to move. Since the surface of the other slider 52 is fixedly installed with a guide rod 54, and the guide rod 54 is slidably inserted into the inner wall of the other mounting slot 51, the guide rod 54 will move synchronously while the two sliders 52 slide on the inner walls of the two mounting slots 51, and the roller 4 will rise and fall synchronously.

[0026] A cutting blade assembly 2 is rotatably mounted on the inner wall of the mounting frame 1. During subsequent use, the user can push the mounting frame 1, and the cutting blade assembly 2 will be driven to rotate by the drive unit 3 to achieve the purpose of weeding. At the same time, when it is necessary to move this device on relatively hard surfaces such as cement floors, the height of the rollers 4 can be controlled by the lifting unit 5, so that when the user pushes the mounting frame 1, the rollers 4 slide in contact with the ground. Since the bottom of the cutting blade assembly 2 is relatively higher than the bottom of the rollers 4, it will not touch the ground, thus avoiding damage to the surface of the cutting blade assembly 2.

[0027] By disassembling the cutting blade assembly 2 into a rotating wheel 21 and several cutting blade bodies 22, the user can first place several cutting blade bodies 22 onto the surfaces of several mounting rods 232, and then thread contact nuts 233 onto the surfaces of several mounting rods 232. This allows the user to install several cutting blade bodies 22 onto the surfaces of several mounting protrusions 231. Therefore, the user can also replace the cutting blade bodies 22 in the above manner to improve the overall service life of the device.

[0028] like Figure 3 As shown, in some embodiments, the main components of the mounting unit 23 are: a plurality of mounting rods 232, which are respectively mounted on the surfaces of a plurality of mounting protrusions 231 that are all mounted on the surfaces of the rotating wheels 21. In use, the user slides a plurality of cutting blades 22 onto the surfaces of the plurality of mounting rods 232, and then threadedly fits abutment nuts 233 onto the surfaces of the plurality of mounting rods 232, thereby realizing the mounting of the plurality of cutting blades 22 on the surfaces of the plurality of mounting protrusions 231. At the same time, a protective shell 6 is fixedly installed on the surface of the main frame 11, which protects the two drive wheels 31 and the transmission belt 34, preventing the transmission belt 34 from being scratched by foreign objects.

[0029] The working process of this utility model is as follows:

[0030] First, when the user needs to remove weeds, he / she needs to push the push rod 12 and slide it on the ground through the roller 4 to move the device on the ground. During this process, the user also needs to control the output end of the drive motor 32 to rotate through the controller 33, which can drive the two drive wheels 31 and the rotating wheel 21 to rotate. Since several cutting blades 22 are installed on the surface of the rotating wheel 21, the rotating cutting blades 22 can achieve the function of removing weeds at this time.

[0031] Secondly, when it is necessary to push the device to slide on a hard ground, the user can rotate the drive threaded rod 53 to drive the roller 4 to descend, so that when the user pushes the main frame 11 later, the bottom of the roller 4 will contact the ground. The user does not need to tilt the push rod 12 excessively, which can ensure that the surface of the cutting blade 22 will not continuously scrape against the ground, thus improving the service life of the device.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
