Description

Technical Field

[0001] This utility model belongs to the field of agricultural machinery technology, specifically relating to a reversible paddy field ditching device. Background Technology

[0002] Paddy fields are widely distributed in my country, and ditching is an essential step in paddy field cultivation. Ditching effectively controls the even distribution of fertilizer and water within the paddy field, thereby promoting the synchronous growth and development of seedlings. While manual ditching can be used for small-scale planting, it is uneven. Large-scale planting requires the use of ditching machines. Currently, most paddy field ditching machines on the market are integrated, independent structures, heavy, and operated separately from leveling machines. This means that ditching and leveling cannot be performed simultaneously; they are independent structures that operate independently and cannot be assembled together. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of the existing technology by providing a reversible paddy field trenching device with a compact structure that can be assembled with a leveling device and can be flipped on the leveling device without hindering the leveling work.

[0004] This utility model is achieved through the following technical solution: a reversible paddy field trenching device, which is composed of a V-shaped trench, characterized in that a U-shaped connector is connected to the upper side of the V-shaped trench through a pin, and the V-shaped trench can be flipped on the U-shaped connector.

[0005] The U-shaped connector has two parallel symmetrical connecting pieces extending outward from its side. Each connecting piece is provided with a pin hole, and each connecting piece is also provided with a working locking component during operation and a flip locking component during flipping.

[0006] The working locking component is a protruding locking buckle provided on the upper and lower surfaces of the connecting piece.

[0007] The working locking component consists of a flip-lock hole on the upper surface of the connecting piece and a working lock hole on the lower surface.

[0008] The U-shaped connector has flat rod mounting holes on its symmetrical U-shaped sides.

[0009] Two upright mounting plates are symmetrically arranged inside the pointed part of the V-shaped groove, and the mounting plates are respectively provided with fixing lock holes and pin holes.

[0010] The beneficial effects of this utility model are as follows: Compared with the prior art, after the V-shaped groove and the U-shaped connector are connected and installed by the pin, the V-shaped groove can be flipped around the pin on the U-shaped connector. That is, when the V-shaped groove does not need to be grooved, it can be flipped and folded without affecting the leveling rod's work in the paddy field; moreover, the V-shaped groove and the leveling rod on the leveler can be detached at will.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] This utility model trenching device is mainly designed to address the shortcomings of traditional trenchers and levelers that cannot work simultaneously. It greatly satisfies the advantage that the trenching device can be arbitrarily rotated on the leveler without affecting the leveling work.

[0022] like Figures 1 to 3 As shown in Embodiment 1, a flip-over paddy field ditching device is composed of a V-shaped trough 1, which facilitates ditching in paddy fields. The V-shaped trough 1 includes a V-shaped groove 101, a pointed part, and a wide opening part. The upper side of the V-shaped trough 1 is connected to a U-shaped connector 3 via a pin 4. When the pin 6 is removed, the V-shaped trough 1 can be flipped on the U-shaped connector 3. The U-shaped connector 3 includes a U-shaped part 301.

[0023] like Figure 2 As shown, two parallel symmetrical connecting pieces (302, 303) extend outward from the side of the U-shaped portion 301. These connecting pieces (302, 303) are used for connection with the V-shaped groove 1. Each connecting piece (302, 303) has a pin hole 305 for mounting a pin 4. Each connecting piece 303 has protruding latches (304, 307) on both its upper and lower sides. The lower set of protruding latches 304 allows the V-shaped groove 1 and the U-shaped connector 3 to be mounted in the pin hole via the pin 4, but the lower pin 6 is directly engaged with the edge of the protruding latches 304. Figure 4 As shown, in order to limit the sliding between the U-shaped connector 3 and the V-shaped groove 1, after the pin 6 is pulled out, the V-shaped groove 1 rotates around the pin 4 on the U-shaped connector 3 and is then locked again by the pin 6 at the edge of a set of protruding latches 307 provided on it.

[0024] like Figure 2 As shown, the U-shaped part 301 of the U-shaped connector 3 is provided with flat rod mounting holes 308 on its side. The flat rod 7 is installed in the U-shaped part 301 and is fastened in the flat rod mounting holes 308 by bolts.

[0025] The V-shaped groove 1 has two upright mounting plates (102, 103) symmetrically arranged inside the pointed part, and the mounting plates (102, 103) are respectively provided with a fixing lock hole 104 and a pin hole 105.

[0026] like Figures 5 to 7 As shown in Embodiment 2, a flip-over paddy field ditching device is composed of a V-shaped trough 1, which facilitates ditching in paddy fields. The V-shaped trough 1 includes a V-shaped groove 101, a pointed part, and a wide opening part. The upper side of the V-shaped trough 1 is connected to a U-shaped connector 3 via a pin 4. When the pin 6 is removed, the V-shaped trough 1 can be flipped on the U-shaped connector 3. The U-shaped connector 3 includes a U-shaped part 301.

[0027] like Figure 6 and Figure 7 As shown, two parallel symmetrical connecting pieces (302, 303) extend outward from the side of the U-shaped portion 301. These connecting pieces (302, 303) are used for connection with the V-shaped groove 1. Each connecting piece (302, 303) has a pin hole 305 for mounting a pin 4. Each connecting piece 303 has a flip-lock hole 309 on its upper surface and a working lock hole 306 on its lower surface. The set of working lock holes on the lower surface is used to insert the pin 6. Figure 7 As shown, this prevents slippage between the U-shaped connector 3 and the V-shaped groove 1 during the trenching process. After the pin 6 is removed, the V-shaped groove 1 rotates around the pin 4 on the U-shaped connector 3 and is then inserted again into a set of flip-lock holes 309 provided above by the pin 6 to fix the V-shaped groove 1 and prevent it from slipping down.

[0028] The installation method of the trenching device of this utility model is as follows: Figure 1 and Figure 2 As shown, the two symmetrical connecting pieces (302, 303) on the U-shaped connector 3 are aligned with the two upright mounting pieces (102, 103) on the V-shaped groove 1. Then, the pin 4 is first passed through the pin hole 105 on the mounting piece and then through the pin hole 305 on the connecting pieces (302, 303). The end of the pin 4 is locked by inserting the linear locking buckle 5 into the end hole to prevent the pin 4 from coming out of the hole. Then, the pin 6 is passed through the fixing locking hole 104 on the mounting piece. At this time, the lower protruding locking buckle 304 provided on the connecting pieces (302, 303) is exactly abutted against the pin 6. Alternatively, the pin 6 can be directly inserted into the working locking hole 306. Finally, by passing the leveling rod 7 through the U-shaped section 301, the trenching device and the leveling machine are installed together; trenching can then be completed normally. When leveling is required instead of trenching, the linear locking buckle 5 is removed, and the pin 6 is pulled out. At this time, the V-shaped groove 1 can be flipped around the fixed locking shaft 4. After flipping to the correct position, the pin 6 is inserted back into the fixed locking hole 104 and secured with the linear locking buckle 5. At this point, the pin 6 is precisely locked on the edge of the upper protruding locking buckle 307; or the pin 6 can be directly inserted into the flipping locking hole 309 for further fixation, thus completing the leveling work without any interference to the leveling process. Figure 3 The direction of the middle arrow indicates the flipping direction of the V-shaped groove 1.
