Description

Technical Field

[0001] This utility model relates to the technical field of sprinkler irrigation equipment, and in particular to a winch sprinkler irrigation vehicle body. Background Technology

[0002] A sprinkler irrigation machine is an irrigation device used in farmland or orchards. It typically uses a winch, which is placed at the edge of the field. The water pipe is retrieved by the winch, which pulls the sprinkler irrigation equipment and allows it to move across the field at a certain speed. At the same time, the sprinkler irrigation equipment is equipped with folding arms on both sides, on which water pipes and sprinkler heads are fixed, allowing for irrigation of a wide range of crops.

[0003] However, this type of sprinkler irrigation machine requires a pulling device (such as a tractor) to pull it to the opposite end of the field before use, and the water supply pipe must be pulled out and connected to the sprinkler equipment. This process often damages the crops in the field. In addition, after each irrigation, the above steps need to be repeated, which makes using the sprinkler irrigation machine difficult and causes more damage to the crops. Therefore, a sprinkler irrigation machine that can avoid these problems is needed. Utility Model Content

[0004] The purpose of this utility model is to solve the above problems and provide a winch sprinkler truck body and a self-propelled sprinkler machine.

[0005] The technical solution of this utility model is as follows: a winch-driven sprinkler irrigation vehicle body, including a frame, a water supply pipe, and a sprinkler frame; the sprinkler frame is installed on both sides of the frame; a winch is set in the middle of the frame, and the winch is rotatably engaged with the top of the frame; the shaft of the winch is a hollow shaft, and the shaft is connected to the sprinkler frame through a rotary joint; the water supply pipe passes from the rear of the frame, passes through the bottom of the winch, and is wound around the winch, with the wound end of the water supply pipe connected to the hollow shaft of the winch. The water supply pipe is connected to the sprinkler frame in sequence through the hollow shaft of the winch and the rotary joint, realizing irrigation of crops on the left and right sides of the device.

[0006] Preferably, the frame includes two opposing triangular support frames and several crossbeams; each end of the crossbeams has several through holes evenly distributed along its length; the crossbeams are connected to the sides of the triangular support frames by bolts. This allows the overall width of the frame to be adjusted according to the row spacing of the crops, providing better adaptability.

[0007] Preferably, a sprocket A is provided at one outer end of the winch, and sprocket A is coaxially arranged with the rotating shaft; a drive motor is correspondingly arranged on the frame, and a sprocket B is arranged on the output shaft of the drive motor, with sprocket A and sprocket B connected by chain drive. The drive motor drives the winch through chain drive, which is simple and effective in structure and more adaptable to harsh environments.

[0008] Furthermore, batteries are used to power the drive motor. Battery power for the drive motor eliminates the need for tethered electrical wires, enhancing the overall flexibility of the device.

[0009] Furthermore, solar panels are installed on top of the frame. These solar panels, positioned atop the winch, provide power to the battery, making the device more flexible and convenient.

[0010] Preferably, a stop is provided at the center of the front side of the frame, which is rotatably connected to the left and right sides of the frame; a U-shaped frame is provided in the middle of the stop, the width of which matches the length of the winch, and the U-shaped frame presses against the water supply pipe; a tension spring is provided at one end of the stop, which is connected to the frame. The tension spring presses the stop against the surface of the water supply pipe on the winch, enabling the winch to tighten the water supply pipe.

[0011] Furthermore, the height of the crossbeam is matched with the height of the bottom of the winch; the crossbeam is made of channel steel;

[0012] A reciprocating screw is located at the center of the rear side of the frame, rotating in conjunction with the frame. A guide roller clamp is fitted onto the reciprocating screw. Two tangent guide wheels are vertically mounted on the guide roller clamp, engaging with the outer surface of the water supply pipe through which the pipe passes. A transverse guide wheel is located at the lower part of the guide roller clamp, resting against the edge of the crossbeam. When the winch rotates to wind the pipe, the reciprocating screw rotates, causing the guide roller clamp to slide laterally, sequentially winding the water supply pipe onto the winch and preventing the pipe from becoming tangled after winding. This also prevents the water supply pipe from rubbing against the crossbeam and causing damage. The transverse guide wheel resting against the crossbeam also prevents the guide roller clamp from rubbing against the crossbeam, thus ensuring smooth movement of the guide roller clamp.

[0013] Furthermore, a sprocket C is provided at the other outer end of the winch; a sprocket D is provided at the corresponding position of the reciprocating screw, and sprocket C and sprocket D are driven by a chain. The reciprocating screw rotates synchronously with the winch through chain drive, enabling the two to stop and move simultaneously and cooperate with each other.

[0014] Preferably, an extension frame is provided at the rear of the frame, and three screws are provided at the end of the extension frame. The three screws are installed into a square frame by angle iron. The square frame is fixed in the middle of the two frames and is perpendicular to the direction of the water supply pipe. Each screw is fitted with a post sleeve. The water supply pipe passes through the square frame. The square frame extends to the rear of the frame through the extension frame, which can constrict the water supply pipe at the rear to a certain extent and prevent the water supply pipe from swinging too much.

[0015] Preferably, the spray frame includes a fixed support frame, a spray pipe, and a plurality of spray heads disposed below the spray pipe; the plurality of spray heads are evenly arranged and connected along the axis of the spray pipe; the rotary joint is connected to the spray pipe via a connecting hose. The connection of the rotary joint to the spray pipe via the connecting hose facilitates the installation and adjustment of the device.

[0016] Preferably, a spare interface is provided in the middle of the rotary joint, and a water gun is installed on the spare interface through a pipe.

[0017] Furthermore, a T-shaped conduit is installed below the spare interface, with the T-shaped conduit positioned horizontally towards the front of the frame. The T-shaped conduit includes a horizontal pipe and a connecting pipe. The middle of the horizontal pipe is connected to the end of the connecting pipe, and the other end of the connecting pipe is connected to a rotary joint. Both ends of the horizontal pipe are sealed, and several nozzles are evenly arranged on the horizontal pipe, with the nozzles facing the ground. The T-shaped conduit and nozzles can irrigate the crops behind it.

[0018] A self-propelled sprinkler irrigation machine utilizing a winch sprinkler vehicle body, wherein a wheel frame is provided at the bottom of the frame, a traveling wheel is provided on the front side of the wheel frame, and a guide wheel is provided on the rear side; the guide wheel is rotatably engaged with the frame.

[0019] A speed reducer is installed in the middle of the wheel frame, and the speed reducer is connected to the hollow shaft of the winch via a chain and sprocket; the speed reducer is also connected to the traveling wheels via a chain and sprocket. This allows the device to move along the gaps in the crops; guide wheels are installed at the rear of the wheel frame, allowing the device to turn quickly when needed.

[0020] Preferably, both the traveling wheel and the guide wheel are equipped with hub motors. Using hub motors to drive the device results in a simpler structure and reduces the risk of damage.

[0021] Furthermore, the diameter of the guide wheel is smaller than that of the traveling wheel, which facilitates the overall steering of the device.

[0022] Preferably, a driver's cab is fixedly installed on the front side of the frame. This allows the driver to sit in the cab and participate in irrigation operations alongside the sprinkler, facilitating observation of the equipment's working status and irrigation results.

[0023] The beneficial effects of this utility model are as follows: The winch-type sprinkler truck body of this utility model has the following advantages:

[0024] 1. In this utility model, the winch and water supply pipe are installed on the frame, and the water supply pipe is connected to the spray frame through a rotary joint, which can realize watering while unwinding or rewinding the water supply pipe, making it convenient to use.

[0025] 2. In this utility model, a reciprocating screw is set in the middle of the frame to limit the water supply pipe, so that the water supply pipe can be wound sequentially on the winch and to avoid friction between the water supply pipe and the crossbeam; during the winding of the water supply pipe, the baffle presses the water supply pipe tightly on the winch, which can help tighten the water supply pipe during the pipe winding process.

[0067] The unwinding and pouring process in this embodiment includes the following steps:

[0068] ① Adjust the overall width of the frame 01 according to the row spacing of the crop, and pull out the water supply pipe 00 on the winch 03, pass it through the square frame and connect it to the water source; connect the sprinkler frame 02 to the rotary joint 32;

[0069] ② Water supply pipe 00 starts supplying water, drive motor 04 starts, and the device moves forward;

[0070] ③ As the device moves forward, the winch 03 rotates synchronously and unwinds;

[0071] ④ The sprinkler stops after traveling a certain distance and then irrigates the crops at the current location;

[0072] Repeat steps ③-④ until the crop in that row is completely irrigated.

[0073] The winding process in this embodiment includes the following steps:

[0074] ①After irrigation is completed, the water supply pipe 00 stops supplying water, and the sprinkler frame 02 drains the water from the water supply pipe 00;

[0075] ②Start drive motor 04, winch 03 to wind up;

[0076] ③ The sprocket C34 and sprocket D52 work together to make the reciprocating screw 05 rotate accordingly;

[0077] The guide roller clamp 51 moves back and forth on the reciprocating screw 05 along with the water supply pipe 00, winding the water supply pipe 00 sequentially onto the winch 03; the water supply pipe 00 is restricted in the middle of the device by the square frame 151.

[0078] Under the action of the tension spring 17, the baffle 14 presses down on the water supply pipe 00 that is wound around the upper winch 03, making the water supply pipe 00 tightly wound.

[0079] Until the water supply pipe is completely retracted.

[0080] Example 3: Example 3 is basically the same as Example 1, and the similarities will not be repeated. The difference is that the fixed support frame is set as a series of folding arm frames, and each section of the folding arm frame is connected to the sprinkler pipe 23 by a flexible hose. This allows the sprinkler frame 02 to be extended, thereby enabling simultaneous irrigation of a wider area of ​​crops.

[0081] Example 4: See Figure 12 Example 4 is basically the same as Example 2, and the similarities will not be repeated. The difference is that a hub motor is installed in both the traveling wheel 131 and the guide wheel 511. The traveling wheel 131 is no longer driven by an electric motor, reducer 133, and sprocket. Instead, a hub motor is used to drive the device, which makes the structure simpler, more effective, and less prone to damage.

[0082] Example 5: Example 5 is basically the same as Example 1, and the similarities will not be repeated. The difference is that: a number of solenoid valves are provided at the rotary joint 32; the number of solenoid valves can control the water volume of the sprinkler frame 02, the T-shaped conduit 322 and the water gun 323 respectively, thereby adjusting the irrigation method for crops.

[0083] In the above embodiments one to five, the triangular support frame 11 can also be adjusted to other support frames with different structures, such as a square support frame, as long as the strength requirements are met. These will not be listed one by one in this patent.
