Description

Technical Field

[0001] This application relates to the field of mudguard technology for micro-tillers, and specifically discloses a foldable mudguard for micro-tillers. Background Technology

[0002] Mini tillers, small agricultural machines used for cultivating land, are powered by small diesel or gasoline engines and are widely applicable to dry land, paddy fields, and orchards in plains, mountains, and hills. Mini tillers can move freely in the fields, making them convenient for users to operate and store.

[0003] A mini tiller mainly consists of working parts, a frame, a transmission system, and a power system. During movement, the rotary tillers control the rotation of the blades to till the land. As the tiller moves, the blades rotate in the direction of travel, pushing soil backward. Typically, mini tillers have mudguards installed between the rotary tillers and the rear seat to prevent soil from splashing backward. Traditional mudguards also have windows allowing the operator to observe the working status of the rotary tillers.

[0004] However, in relatively moist soil, the mud adheres more strongly. During prolonged operation of the mini-tiller, splashed mud will accumulate on the inside of the mudguards. For some mudguards with viewing windows, mud will also adhere to the windows, affecting visibility. After using the mini-tiller, the mudguards must be removed separately for cleaning. Existing mudguards lack adjustment functions and cannot automatically clean the mud adhering to their inner sides.

[0005] Therefore, the inventors have provided a foldable mudguard for a micro-tiller to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to solve the problem that the mudguards of traditional micro-tillers cannot clean the mud attached to their inner side on their own.

[0007] To achieve the above objectives, the basic solution of this utility model provides a foldable mudguard for a micro-tiller, including side baffles detachably connected to both sides of the frame, a fixed baffle with one end fixed between the side baffles, and a movable baffle slidably connected between the side baffles along the extension direction of the top surface of the fixed baffle. The movable baffle is located above the fixed baffle. The side baffles have arc-shaped grooves. One end of the movable baffle is fixedly connected to a pushing structure that passes through the arc-shaped groove. The end of the fixed baffle near the movable baffle is fixedly connected to a main scraper that fits against the bottom surface of the movable baffle. The end of the movable baffle near the fixed baffle is fixedly connected to a secondary scraper that extends into the bottom surface of the fixed baffle. Gaps for the secondary scrapers to travel are formed between the two sides of the fixed baffle and the side baffles.

[0008] Furthermore, the length of the movable baffle is equal to the length of the fixed baffle.

[0009] Furthermore, both the movable baffle and the fixed baffle are arc-shaped with openings facing downwards, and the curvature of the movable baffle and the fixed baffle are equal.

[0010] Furthermore, the inner side of the side baffle is provided with a guide groove extending along the top surface of the fixed baffle, and guide sliders that slide in the guide groove are fixedly connected to both sides of the movable baffle.

[0011] Furthermore, the pushing structure includes a sleeve fixed to the end of the movable baffle away from the fixed baffle and a gripping rod connected to the sleeve.

[0012] Furthermore, the movable baffle has several windows equidistantly spaced, each window having a rotatably connected sealing plate. One side of the movable baffle is provided with a belt drive mechanism for uniformly rotating the sealing plates. The pulley on one side of the belt drive mechanism is coaxially fixed to an input bevel gear. The handle is rotatably limited by the sleeve. The end of the handle extends out of the sleeve and is coaxially fixed to an output bevel gear that meshes with the input bevel gear.

[0013] Furthermore, each of the viewing windows is rotatably connected to a rotating rod driven by a belt transmission mechanism, and the sealing plate is fixedly connected to the rotating rod. The rotating rod is located on the side of the viewing window away from the fixed baffle.

[0014] Furthermore, each end of the movable baffle is fixedly connected with a side scraper for attaching to the side baffle of the same side.

[0015] The principle and effect of this solution are as follows:

[0016] 1. Compared with the prior art, after the mini-tiller finishes working, the operator can sit directly on the seat and push the moving baffle directly towards the fixed baffle by using the lever. During this process, the main scraper scrapes off the mud attached to the bottom surface of the moving baffle, and the auxiliary scraper scrapes off the mud attached to the bottom surface of the fixed baffle, which solves the problem that the mudguards of traditional mini-tillers cannot clean the mud attached to the inside on their own.

[0017] 2. Compared with the prior art, the present invention is also provided with a side scraper, which can scrape off the soil attached to the side baffle.

[0018] 3. Compared with the prior art, when it is necessary to inspect the working condition of the rotary tiller, this utility model only requires rotating the handle. The rotation of the handle is driven by bevel gear transmission and belt transmission mechanism to drive the rotating rod and the sealing plate to rotate, thus opening the viewing window.

[0024] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0025] The reference numerals in the accompanying drawings include: frame 1, side baffle 2, movable baffle 3, sleeve 4, grip rod 5, limiting ring block 6, output bevel gear 7, input shaft 8, guide slider 9, fixed baffle 10, auxiliary scraper 11, main scraper 12, connecting rod 13, rotating rod 14, sealing plate 15, and side scraper 16.

[0026] A foldable mudguard for a micro-tiller, implementing, for example Figure 1 , Figure 2 and Figure 3 As shown:

[0027] It includes two side baffles 2, a fixed baffle 10 fixed between the side baffles 2, and a movable baffle 3. The side baffles 2 are respectively installed on both sides of the frame 1 by bolts.

[0028] The left end of the fixed baffle 10 is fixed between two side baffles 2. The movable baffle 3 is installed between the two side baffles 2 and can slide along the extension direction of the top surface of the fixed baffle 10. In this embodiment, the length of the movable baffle 3 is equal to the length of the fixed baffle 10, and both the movable baffle 3 and the fixed baffle 10 are arc-shaped with downward openings, and the curvatures of the movable baffle 3 and the fixed baffle 10 are equal. The movable baffle 3 is located above the fixed baffle 10, and the inner side of the side baffle 2 has a guide groove extending along the top surface of the fixed baffle 10. Guide sliders 9 are fixed on both sides of the movable baffle 3 and slide within the guide grooves, respectively.

[0029] Arc-shaped grooves are also formed on the side baffles 2, and a pushing structure passing through the arc-shaped grooves is fixedly installed on the right end of the movable baffle 3. The pushing structure includes a sleeve 4 fixed to the right end of the movable baffle 3 and a handle 5 connected to the sleeve 4.

[0030] Specifically, a connecting rod 13 is fixed to the right end of each movable baffle 3. The connecting rod 13 passes through the arc-shaped groove, and the sleeve 4 is fixed to the connecting rod 13. The left end of the gripping rod 5 passes through the sleeve 4. Two coaxial limiting ring grooves are also opened inside the sleeve 4. The gripping rod 5 is formed with limiting ring blocks 6, which can be inserted into the limiting ring grooves and rotate around the axis within them.

[0031] Furthermore, in this embodiment, the movable baffle 3 is also provided with several windows at equal intervals, each window containing a rotatable sealing plate 15. The movable baffle 3 is equipped with a belt drive mechanism for uniformly rotating the sealing plates 15. Each window contains a rotatable rotating rod 14, with the right end of the sealing plate 15 fixedly connected to the rotating rod 14. The rotating rod 14 is installed on the side of the window away from the fixed baffle 10, i.e., the right side. The ends of the rotating rods 14 extend out of the movable baffle 3. The belt drive mechanism includes an input shaft 8 mounted on the movable baffle 3, a pulley group one mounted between the input shaft 8 and the adjacent rotating rod 14, and a pulley group two mounted between adjacent rotating rods 14. A belt is installed between the pulley group one and the pulley group two.

[0032] An input bevel gear is also coaxially fixedly mounted on the input shaft 8, and an output bevel gear 7 that meshes with the input bevel gear is fixedly mounted on the left end of the handle 5.

[0033] like Figure 3 and Figure 4 As shown, a main scraper 12, which fits against the bottom surface of the movable baffle 3, is fixed to the right end of the fixed baffle 10, that is, the end near the movable baffle 3. A secondary scraper 11, which extends into the bottom surface of the fixed baffle 10, is fixed to the left side of the movable baffle 3, that is, the end near the fixed baffle 10. Gaps are formed between the two sides of the fixed baffle 10 and the side baffle 2 to allow the secondary scraper 11 to travel.

[0034] Furthermore, both ends of the movable baffle 3 are respectively fixed with side scrapers 16 for attaching to the side baffle 2 of the contract side.

[0035] When using this invention, during the operation of the micro-tiller, the operator sits as follows: Figure 1 On the seat shown, pull the handle 5 and move the baffle 3 backward to cover the rotary tiller blades below to prevent soil from splashing. At this time, the sealing plate 15 closes the viewing window.

[0036] When it is necessary to check the working condition of the rotary tiller, simply rotate the handle 5. The rotation of the handle 5 drives the pulley group one and pulley group two in the belt drive mechanism to rotate synchronously through the bevel gear transmission, which in turn drives the rotating rod 14 and the sealing plate 15 to rotate, thus opening the viewing window.

[0037] After the mini-tiller finishes working, the operator can push the movable baffle 3 directly towards the fixed baffle 10. During this process, the sealing plate 15 is in the viewing window state, and the main scraper 12 scrapes off the soil attached to the bottom surface of the movable baffle 3, the auxiliary scraper 11 scrapes off the soil attached to the bottom surface of the fixed baffle 10, and the side scraper 16 scrapes off the soil attached to the side baffle 2.

[0038] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
