[0005] The device is suitable for square standard construction paddy field, the mother vehicle is matched with fertilizer solution or liquid medicine, the mother vehicle walks along the machine path, every interval is perpendicular to the machine path, the sub-vehicle walks along the dike, the reel on the sub-vehicle unwinds the pipe, lays forward, the sub-vehicle sprays fertilizer or liquid medicine on one side of the dike, when the sub-vehicle reaches the end of the dike, the track assembly drives the sub-vehicle to retreat, at this time, the pipe is wound, and the other side of the dike is sprayed with fertilizer or liquid medicine. The range of unilateral spraying can be 1 times or 0.5 times of the dike interval, and the above-mentioned sequential spraying can continuously spray fertilizer and medicine on the standard construction paddy field, which is simple in operation, high in efficiency, large in spraying area and uniform in spraying.

[0006] As preferred, the two sides of the reel are provided with supports, the supports are vertically arranged on the two sides of the sub-vehicle, the reel comprises a reel inner cylinder and a reel outer cylinder which are nested with each other, the two ends of the reel inner cylinder are provided with reel shafts arranged on the two supports, the reel outer cylinder is provided with outer cylinder bearings between the two reel shafts, the two end faces of the reel inner cylinder and the reel outer cylinder are provided with ratchets; the output end of the track drive motor is further provided with a drive shaft, the drive shaft and the left end reel shaft are respectively provided with an unwinding belt set and a winding belt set which are driven when unwinding and winding; the right end of the reel outer cylinder is fixed with a tension driven pulley, the sub-vehicle is further provided with a tension motor, the output end of the tension motor is provided with a tension driving pulley, and the tension driving pulley and the tension driven pulley are provided with a tension belt; the ratchet comprises an inner wheel and an outer wheel, the inner wheel is fixedly connected with the reel inner cylinder, the outer wheel is fixedly connected with the reel outer cylinder, the inner side of the outer wheel is provided with a ratchet, the inner wheel is provided with a spring slot, and the spring slot is provided with a spring and a spring plate.

[0007] The device belongs to agricultural machinery, and the use environment is complex. Moreover, since the winding wheel may be multi-layer winding, the length of each winding and unwinding of the winding wheel cannot be accurately grasped, so it is impossible to control the winding and unwinding of the winding tube to keep high synchronization with the walking speed of the child car. If the unwinding speed is less than the walking speed of the child car, or the winding speed is greater than the walking speed of the child car, it will cause the winding tube to pull the child car strongly, causing the child car to deviate. When the unwinding speed is greater than the walking speed of the child car, or the winding speed is less than the walking speed of the child car, the winding tube cannot be laid flat, or it will be loose when winding, which will also hinder the walking of the child car. Therefore, the device is driven by the unwinding belt group and the winding belt group respectively when winding and unwinding, and different transmission ratios are ensured to ensure that the unwinding speed is greater than the walking speed of the child car when the child car advances, and the winding speed is less than the walking speed of the child car when the child car retreats. Then, the tensioning motor is intermittently started to drive the outer cylinder of the winding wheel to rotate relative to the inner cylinder of the winding wheel, and the loose winding tube is wound to compensate. Once the tension exceeds the set threshold, it means that the winding tube has been basically tightened, and the tension threshold can be controlled by belt slip or by the second electromagnetic clutch. The tension threshold is much smaller than the pulling force on the child car caused by the insufficient length of the winding tube, which can ensure that the winding wheel compensates the tightening of the winding tube without generating excessive pulling force on the child car. In actual use, a winding tube with sufficient length can be reserved inside the inner cylinder of the winding wheel to compensate for the expansion and contraction caused by the different speeds of the inner and outer cylinders.

[0008] As a preferred, the unwinding belt group includes an unwinding driving pulley sleeved on the driving shaft and an unwinding driven pulley sleeved on the winding wheel shaft, an unwinding synchronous belt is sleeved between the unwinding driving pulley and the unwinding driven pulley, an unwinding one-way bearing is arranged between the unwinding driving pulley and the driving shaft, and an unwinding one-way bearing is arranged between the unwinding driven pulley and the winding wheel shaft; the winding belt group includes a winding driving pulley sleeved on the driving shaft and a winding driven pulley sleeved on the winding wheel shaft, a winding synchronous belt is sleeved between the winding driving pulley and the winding driven pulley, a winding one-way bearing is arranged between the winding driving pulley and the driving shaft, and a winding one-way bearing is arranged between the winding driven pulley and the winding wheel shaft; the directions of the winding one-way bearing and the unwinding one-way bearing are opposite. The winding one-way bearing and the unwinding one-way bearing can be one-way transmission. When the child car advances, the unwinding one-way bearing is enabled, and the winding one-way bearing is idling. When the child car retreats, the opposite is true.

[0009] As a preferred, the transmission ratio of the unwinding belt group is smaller than that of the winding belt group, and the forward linear speed of the unwinding state track assembly is smaller than the unwinding linear speed of the winding wheel, and the backward linear speed of the winding state track assembly is greater than the winding linear speed of the winding wheel.

[0010] As a preferred, the unwinding synchronous belt and the winding synchronous belt are both toothed belts.

[0011] As preferred, a first electromagnetic clutch is arranged between the track drive motor output end and the driving shaft, which can be cut off. When the trolley is running alone, the first electromagnetic clutch can be cut off, and the winding and unwinding operation is not performed.

[0012] As preferred, the tensioning motor is an intermittent starting motor, and a second electromagnetic clutch is arranged between the tensioning motor output end and the tensioning driving pulley. The second electromagnetic clutch and the tensioning belt form a double slip insurance, which ensures that the tensioning force does not exceed the set threshold.

[0013] As preferred, the tensioning belt is a flat belt.

[0014] As preferred, the spring of the ratchet wheel pressing piece is replaceable. Under the action of the spring pressing force, the slip threshold of the pressing piece and the ratchet is greater than the load of the outer cylinder of the winding wheel during unwinding. Although the design purpose of the ratchet structure is to drive forward and realize one-way transmission in the reverse direction, by replacing a spring with higher strength, the spring resistance that needs to be overcome by the slip of the pressing piece and the ratchet is also increased. Since the outer cylinder of the winding wheel is almost idling during unwinding operation, by selecting the strength of the spring, the winding wheel outer cylinder can be driven to unwind when the ratchet rotates in the reverse direction, and sufficient load is generated when the tensioning belt is intervened, so that the inner and outer cylinders rotate relatively to tension the winding pipe.

[0015] As preferred, a multi-stage filter is connected to the water inlet pipe of the mother trolley, and a sewage valve is connected below each stage of the multi-stage filter; a direct-current stirring motor is arranged on the top of the mother liquid barrel and the dilution barrel of the mother trolley respectively; the mother liquid barrel is connected to the dilution barrel through a peristaltic pump, and the dilution barrel is connected to the winding pipe through a plunger pump; a diesel generator and a mother trolley battery are arranged on the mother trolley.

[0016] The application can continuously spray fertilizer and pesticide in standard constructed rice fields, and has the advantages of simple operation, high efficiency, large spraying area, uniform spraying, no pulling force on the trolley when the trolley walks back and forth, and tightening of the winding pipe through tensioning compensation.

[0029] As shown in the figure, Figure 3 The output end of the track drive motor 24 is provided with a driving shaft 26 through the first electromagnetic clutch 25, and the driving shaft 26 and the left winding wheel shaft 36 are respectively provided with a winding release transmission belt group and a winding transmission belt group.

[0031] The operation mode is as shown in the figure Figure 5 , 6As shown, the device is used in square standard construction paddy field, the shaded part in the figure is the worked field block 56, and the white part is the unworked field block 57. The mother vehicle 1 is matched with fertilizer or pesticide liquid, and the mother vehicle 1 walks along the machine path 54. The field ridge 55 is arranged perpendicularly to the machine path at a certain distance, and the child vehicle 2 walks along the field ridge 55. When the track assembly drives the child vehicle to move forward, the winding wheel on the child vehicle unwinds the pipe and lays it forward. The child vehicle simultaneously sprays and applies fertilizer or pesticide to the paddy field on one side of the field ridge 55. When the child vehicle reaches the end of the field ridge, the track assembly drives the child vehicle to move backward. At this time, the pipe is wound up, and the paddy field on the other side of the field ridge is sprayed and applied with fertilizer or pesticide. The range of unilateral spraying can be 1 times the distance between the field ridges, so that the field block is worked once every other field ridge, as shown in Figure 5 The range of unilateral spraying can also be 0.5 times the distance between the field ridges, so that the field block needs to be worked once every field ridge. The child vehicle on the most side can use the machine path 54, as shown in Figure 6 .

[0032] In actual operation, since the length of each winding and unwinding of the winding wheel cannot be accurately grasped, the winding and unwinding of the pipe cannot be highly synchronized with the walking speed of the child vehicle. If the unwinding speed is less than the walking speed of the child vehicle, or the winding speed is greater than the walking speed of the child vehicle, the pipe will pull the child vehicle strongly, causing the child vehicle to deviate. When the unwinding speed is greater than the walking speed of the child vehicle, or the winding speed is less than the walking speed of the child vehicle, the pipe cannot be laid flat, or it is loose when wound up, which also hinders the walking of the child vehicle. Therefore, in this embodiment, the unwinding belt group and the winding belt group are driven respectively when winding and unwinding, different transmission ratios are ensured, the unwinding speed is greater than the walking speed of the child vehicle when the child vehicle moves forward, and the winding speed is less than the walking speed of the child vehicle when the child vehicle moves backward. The tensioning motor is intermittently started to drive the outer cylinder of the winding wheel to rotate relative to the inner cylinder of the winding wheel, and the loose pipe is wound and compensated. Once the tensioning force exceeds the set threshold, it means that the pipe has been basically tightened. The tensioning force threshold can be controlled by belt slip or by the second electromagnetic clutch. The tensioning force threshold is much smaller than the pulling force of the pipe length deficiency on the child vehicle, which can ensure that the winding wheel compensates and tightens the pipe without generating excessive pulling force on the child vehicle.
