Abstract
Description
Technical Field
[0001] This utility model relates to the field of rotary tiller technology, and in particular to a rotary tiller protective cover. Background Technology
[0002] Rotary tillers are commonly used agricultural tillage equipment. During rotary tillage, to prevent soil from flying out of the tiller blades and causing accidental injury, especially with walk-behind rotary tillers where the operator is very close to the blades, it is crucial to install a protective cover on the rotary tiller blades. However, many protective covers are semi-cylindrical structures composed of multiple sheet metal parts, usually welded or bolted together. Once installed on the rotary tiller, cleaning, repairing, or replacing the tiller blades and other components requires removing the cover, which is time-consuming, laborious, and difficult due to its large size. There is an urgent need for a rotary tiller protective cover that eliminates the need for disassembly when cleaning, repairing, or replacing the tiller blades and other components. Utility Model Content
[0003] The purpose of this utility model is to provide a rotary tiller cover for rotary tillers, so as to solve the problem that existing rotary tiller covers need to be disassembled and installed during major overhauls or cleaning of the rotary tillers, and the disassembly and installation process is time-consuming and laborious.
[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0005] A rotary tiller cover includes a frame, a protective plate, a hook plate, and an adjustable re-ridge-opening mechanism. The protective plates are symmetrically arranged and rotatably mounted on both sides of the frame. The hook plates are symmetrically arranged and rotatably mounted on the top of the frame. The outer ends of the hook plates are provided with multiple hook grooves. The top of the protective plate is provided with a pin plate. A pin that matches the hook groove is slidably installed in the pin hole of the pin plate. The adjustable re-ridge-opening mechanism is located at the tail of the frame.
[0006] A further technical solution is that the number of hook grooves is multiple and they are inclined strip structures, with the inclination direction inclined towards the far end of the hook plate.
[0007] A further technical solution is as follows: the adjustable ridge-opening mechanism includes a fixed plate, a front ridge-opening plate, a rear ridge-opening plate, and a ridge cutter. The fixed plate is installed at the tail of the frame. The top of the front ridge-opening plate is rotatably connected to the frame, and an arc-shaped groove is provided on the extension plate of the front ridge-opening plate. The fixed plate is provided with a bolt and nut pair that matches the arc-shaped groove. The rear ridge-opening plate and the ridge cutter are both rotatably installed on the fixed plate and are both locked to the fixed plate by the bolt and nut pair.
[0008] A further technical solution is that the ridging area of the front ridging board is smaller than the ridging area of the rear ridging board.
[0009] A further technical solution is that the blade of the ridge cutter is provided with multiple threaded holes.
[0010] A further technical solution is that the frame and the protective plate are connected by hinges.
[0011] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects:

[0025] This implementation example Figure 1 , Figure 2 , Figure 3 , Figure 3 , Figure 4 and Figure 5 As shown, a rotary tiller cover for a rotary tiller includes a frame 1, a protective plate 2, a hook plate 3, and an adjustable re-ridge-opening mechanism 4. The protective plates 2 are symmetrically arranged and rotatably installed on both sides of the frame 1. The hook plates 3 are symmetrically arranged and rotatably installed on the top of the frame 1. The outer end of the hook plate 3 is provided with multiple hook grooves 5. The top of the protective plate 2 is provided with a pin plate 6. A pin 7 that matches the hook groove 5 is slidably installed in the pin hole of the pin plate 6. The adjustable re-ridge-opening mechanism 4 is located at the tail of the frame 1.
[0026] The working process of this utility model is as follows: When it is necessary to disassemble, repair, or clean the rotary tiller blades, first pull the pin 7 on one of the protective plates 2 out of the groove of the hook plate 3. Then, lift the hook plate 3 and the protective plate 2 upwards simultaneously until they reach a suitable position. The pin hole of the pin plate 6 on the protective plate 2 corresponds to another hook groove 5 on the outer end of the hook plate 3. Then, insert the pin 7 again to lock the protective plate 2 and the hook plate 3 again. Adjust the other protective plate 2 in the same way. Finally, both protective plates 2 are tilted upwards, exposing the rotary tiller blades, which facilitates the disassembly, repair, or cleaning of the rotary tiller blades and other components. After completing the work, reset the protective plate 2 and prepare for rotary tilling.
[0027] It is worth noting that when adjusting the protective plate 2 to tilt upwards, after releasing the lock between the protective plate 2 and the hook plate 3, the protective plate 2 can be lifted upwards using the support rod alone. This operation method is quicker and simpler.
[0028] Preferably, the number of hook grooves 5 is multiple and they are inclined strip structures, with the inclined direction facing the far end of the hook plate 3.
[0029] The groove 5 is inclined and has a strip-shaped structure to ensure that the groove 5 can lock the protective plate 2 within a large range when adjusting the position of the protective plate 2. Example
[0030] Based on the above embodiments, this embodiment shows that the adjustable ridge-opening mechanism 4 includes a fixed plate 8, a front ridge-opening plate 9, a rear ridge-opening plate 10, and a ridge cutter 11. The fixed plate 8 is installed at the tail of the frame 1. The top of the front ridge-opening plate 9 is rotatably connected to the frame 1, and an arc-shaped groove 12 is provided on the extension plate of the front ridge-opening plate 9. The fixed plate 8 is provided with a bolt and nut pair that matches the arc-shaped groove 10. The rear ridge-opening plate 10 and the ridge cutter 11 are both rotatably installed on the fixed plate 8 and are both locked to the fixed plate 8 by the bolt and nut pair.
[0031] The front ridging plate 9, rear ridging plate 10, and ridge cutter 11 are installed on the fixed plate 8. When the rotary tiller pulls the frame 1 forward, the front ridging plate 9 separates the soil to form ridges, while the rear ridging plate 10 re-rafts on the basis of the front ridging plate 9. This ensures the ridging effect and reduces the working pressure on each ridging plate by performing two ridging operations. The ridge cutter 11 slides within the furrow, generally within the soil. This serves two purposes: first, to prevent the ridging plate 10 from shaking, and second, to mark furrow lines within the furrow for later use.
[0032] Preferably, the ridging area of the front ridging board 9 is smaller than the ridging area of the rear ridging board 10.
[0033] The front ridging plate 9 and the rear ridging plate 10 share the ridging pressure.
[0034] Preferably, the blade of the cutting tool 11 is provided with multiple threaded holes.
[0035] A suitable threaded hole of appropriate height can be selected and bolted to the end of the fixing plate 8 to adjust the depth of the furrow.
[0036] Preferably, the frame 1 and the protective plate 2 are connected by hinges.
[0037] Preferably, the protective plate 2 has an arc-shaped structure.
[0038] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
