[0004] However, during the implementation of the above technical solution, it was found that there were at least the following technical problems: the above-mentioned walking tractor, due to its heavy weight, is inconvenient when replacing the paddy field wheels and is difficult to use in multiple terrains. Utility Model Content

[0005] (1) Technical problems solved

[0006] In view of the deficiencies of the existing technology, the utility model provides a universal walking tractor for farmland operations, which solves the technical problem that the above-mentioned walking tractors are heavy, inconvenient to replace paddy field wheels, and difficult to use in various terrains.

[0007] (2) Technical solution

[0008] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0009] A universal walking tractor for farmland operations comprises a frame, a sliding rod is fixedly installed on the bottom end of the frame, a slider is slidably installed on the side end of the sliding rod, a threaded rod is rotatably installed on the side end of the slider, a driven plate is rotatably installed on the bottom end of the slider, a support plate is rotatably installed on the bottom end of the driven plate, a threaded block is rotatably installed on the top end of the support plate, a transmission frame is fixedly installed on the side end of the threaded rod; the threaded block is threadedly connected to the threaded rod, an engine is fixedly installed on the top end of the frame, a water tank is fixedly installed on the top end of the engine, a condensation box is fixedly installed on the top end of the water tank, a flap is rotatably installed on the side end of the condensation box, and a magnetic strip is fixedly installed on the side end of the condensation box.

[0010] Preferably, a support frame is rotatably mounted on a side end of the frame, and two tires are symmetrically mounted on both sides of the frame.

[0011] Preferably, two transmission belts are installed on the side ends of the engine; the engine drives the frame through the transmission belts.

[0012] (3) Beneficial effects

[0013] 1. When the paddy field wheel needs to be replaced, slide the slider to either end of the slide bar, start the crank handle of the walking tractor, insert it into the transmission frame, and the crank handle buckles can clamp the two ends of the main transmission frame. Turn the crank handle to drive the threaded rod to rotate through the transmission frame. Since the threaded rod is threadedly connected to the threaded block, the rotation of the threaded rod will drive the threaded block to slide on the threaded rod. When the threaded block slides toward the end of the slider, it drives the support plate to rotate, so that the support plate opens to support the ground and lifts one side of the tractor, and then unscrew the nut on the side end of the tire to complete the replacement. After one side is replaced, rotate the transmission frame in the opposite direction, retract the support plate, and slide the slider to the other end of the slide bar to replace the other tire. By rotating the threaded rod to lift the support plate, the paddy field wheel is easily replaced and can be used in multiple terrains.

[0014] 2. When in use, pull open the flap to reveal the water inlet at the top of the water tank. During use, the water tank will cool the engine. When the water inside the water tank is evaporated into water vapor, the rising water vapor will condense into small streams at the top of the condensation box, and then slide down along the curved surface of the top of the condensation box and return to the inside of the water tank. The top of the condensation box is thinner, which is conducive to heat dissipation when the water vapor condenses. The evaporated water vapor is re-condensed through the condensation box and injected into the water tank, thereby improving the utilization rate of water resources and avoiding frequent water addition to the water tank.

[0021] The embodiment of the present application provides a universal walking tractor for farmland operations, which effectively solves the technical problem that the above-mentioned walking tractors are inconvenient to replace the paddy field wheels due to their large weight and are difficult to use in multiple terrains. When the paddy field wheels need to be replaced, the slider is slid to either end of the slide bar, the walking tractor start crank is inserted into the transmission frame, and the crank buckle can clamp the two ends of the main transmission frame. Turning the crank drives the threaded rod to rotate through the transmission frame. Since the threaded rod is threadedly connected to the threaded block, the rotation of the threaded rod will drive the threaded block to slide on the threaded rod. When the threaded block slides toward the end of the slider, it drives the support plate to rotate, so that the support plate opens to support the ground and lifts up one side of the tractor, and then the nut at the side end of the tire is unscrewed to complete the replacement. After one side is replaced, rotate the transmission frame in the opposite direction, retract the support plate and slide the slider to the other end of the slide rod to replace the other tire. The support plate is lifted by rotating the threaded rod, which makes it easy to replace the paddy field wheel and can be used in multiple terrains. When in use, pull open the flap to reveal the water inlet at the top of the water tank. During use, the water tank will cool the engine. When the water inside the water tank is evaporated into water vapor, the rising water vapor will condense into small streams at the top of the condensation box, and then slide down along the arc surface at the top of the condensation box back to the inside of the water tank. The top of the condensation box is thinner, which is conducive to heat dissipation when the water vapor condenses. The evaporated water vapor is re-condensed through the condensation box and injected into the water tank, thereby improving the utilization rate of water resources and avoiding the effect of frequently adding water to the water tank.

[0022] Example

[0023] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown, the technical solution in the embodiment of the present application effectively solves the technical problem that the walking tractor mentioned above is inconvenient when replacing paddy field wheels due to its heavy weight and is difficult to use in multiple terrains. The overall idea is as follows:

[0024] In response to the problems existing in the prior art, the utility model provides a universal hand-held tractor for farmland operations, including a frame 1, a slide bar 2 is fixedly installed on the bottom end of the frame 1, a slider 3 is slidably installed on the side end of the slide bar 2, a threaded rod 6 is rotatably installed on the side end of the slider 3, and a driven plate 4 is rotatably installed on the bottom end of the slider 3.

[0025] The bottom end of the driven plate 4 is rotatably mounted with a support plate 5, the top end of the support plate 5 is rotatably mounted with a threaded block 17, and the side end of the threaded rod 6 is fixedly mounted with a transmission frame 7; the threaded block 17 is threadedly connected to the threaded rod 6, the top end of the frame 1 is fixedly mounted with an engine 8, the top end of the engine 8 is fixedly mounted with a water tank 11, and the top end of the water tank 11 is fixedly mounted with a condensation box 12.

[0026] A flap 15 is rotatably installed on the side end of the condensation box 12, a magnetic strip 16 is fixedly installed on the side end of the condensation box 12, a support frame 13 is rotatably installed on the side end of the frame 1, two tires 14 are symmetrically installed on both sides of the frame 1, and two transmission belts 9 are installed on the side end of the engine 8; the engine 8 drives the frame 1 through the transmission belt 9.

[0027] Working principle:

[0028] The first step is that when the paddy field wheel needs to be replaced, the slider 3 is slid to either end of the slide bar 2, the walking tractor is started and the crank handle is inserted into the transmission frame 7. The crank buckle can clamp the two ends of the main transmission frame 7, and the crank handle is turned to drive the threaded rod 6 to rotate through the transmission frame 7. Since the threaded rod 6 is threadedly connected to the threaded block 17, the rotation of the threaded rod 6 will drive the threaded block 17 to slide on the threaded rod 6. When the threaded block 17 slides toward the end of the slider 3, it drives the support plate 5 to rotate, so that the support plate 5 opens to support the ground and lifts one side of the tractor, and then the nut at the side end of the tire 14 is unscrewed to complete the replacement. When one side is replaced, the transmission frame 7 is rotated in the opposite direction, the support plate 5 is retracted, and the slider 3 is slid to the other end of the slide bar 2 to replace the other tire 14. The support plate 5 is lifted by rotating the threaded rod 6, which achieves the effect of easy replacement of paddy field wheels and can be used in multiple terrains.

[0029] The second step is that when in use, the water inlet at the top of the water tank 11 can be leaked by pulling open the flap 15. During use, the water tank 11 will cool the engine 8. When the water inside the water tank 11 is evaporated into water vapor, the rising water vapor will condense into small streams at the top of the condensation box 12, and then slide down along the curved surface at the top of the condensation box 12 and return to the inside of the water tank 11. The top of the condensation box 12 is thinner, which is conducive to heat dissipation when the water vapor condenses. The evaporated water vapor is re-condensed through the condensation box 12 and injected into the water tank 11, thereby improving the utilization rate of water resources and avoiding frequent water addition to the water tank 11.

[0030] Finally, it should be noted that the above embodiments are merely examples for the purpose of illustrating the present invention and are not intended to limit the embodiments. Those skilled in the art will readily appreciate that other variations or modifications based on the above description are possible. It is not necessary and impossible to provide an exhaustive list of all possible embodiments. However, any obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
