In practical application, because the field area is large, the length of each operation area is long, so that each watering cart moves from one end of the operation area close to a water supply point to one end of the operation area far away from the water supply point, a hose with the length larger than that of the operation area is needed to supply water to the operation area, the length of the hose is at least larger than the distance between the operation area with the farthest distance from the water supply point and the length of the operation area, and therefore when the watering cart waters and irrigates in the operation area far away from the water supply point, the hose still supplies water for the watering cart running in the operation area, and the hose cannot be pulled due to the fact that the length of the hose is insufficient, the connection position of the hose and the watering cart is loosened or the connection position of the hose and the water supply point is loosened, and water leakage is caused. In addition, since the hose is wound in the storage groove of the hose storage device 3 when the end of the working area close to the water supply point is close to the end of the working area, if the storage groove is wide enough to accommodate only one circle of hose, so that the hose is wound in many turns when being wound in the storage groove of the hose storage device 3, and the height of the cylindrical surface 32 of the hose storage device 3 is high, the width of the storage groove of the hose storage device 3 is usually much larger than the diameter of the hose, the cylindrical surface 32 can wind many turns of hose side by side in the storage groove, after the first layer of many turns of hose is wound in the storage groove of the hose storage device 3, another layer of many turns of hose is wound above the bottom layer of hose, and the hose is wound and stored in turn until the watering cart returns to the end of the working area close to the water supply point, and in order to keep the multiple layers of hose wound in the storage groove of the hose storage device 3 stable, after the hose is completely wound into the storage groove of the hose storage device 3, the height of the hose is not greater than the depth of the storage groove of the hose storage device 3.
Since the rotating angular velocity of the rotating shaft 31 of the hose storage device 3 is always kept constant during the process of winding the hose, for convenience of description, the multiple turns of the hose wound on the bottommost layer of the cylindrical surface 32 are collectively referred to as a first layer of hose, the multiple turns of the hose wound on the first layer of hose are collectively referred to as a second layer of hose, and so on, and the radius of the hose is set to r 1 When the cylindrical surface 32 winds the first layer of hose, the arc length of the cylindrical surface 32 rolling one circle along with the rotating shaft 31 is L 1 When the cylindrical surface 32 winds the second layer of hose, the arc length of the cylindrical surface 32 rolling one circle along with the rotating shaft 31 is L 2 ＝2πR+r 1 By analogy, when the cylindrical surface 32 winds the nth layer of hose, the arc length of the cylindrical surface 32 rolling for one circle along with the rotating shaft 31 is L n ＝2π[R+(n-1)r 1 ]Wherein n.gtoreq.1, so that L 1 ＜L 2 ＜……L n Therefore, under the condition that the rotating speed of the driving motor 1 of the driving device is kept unchanged, the first group of rotating wheels 2 keeps rotating at a constant speed so as to keep the watering cart running at a constant speed, but when the watering cart moves from one end close to a water supply point to one end far away from the water supply point, the pipe placing speed of the hose storage device 3 is gradually reduced, and when the watering cart moves from one end far away from the water supply point to one end close to the water supply point, the pipe receiving speed of the hose storage device 3 is gradually increased, because the first output end and the second output end of the output shaft 11 are respectively connected with the first output end and the second output end of the output shaftThe same angular velocity exists, so that the output shaft 11 rotates once, the first driving gear 12 and the second driving gear 14 also rotate once, the first driving gear 12 drives the rotating shaft 31 to rotate by meshing with the driving gear or combining with the driving gear set, the rotating shaft 313 of the rotating shaft 31 is driven to rotate, and the transmission ratio of the first driving gear 12 to the driving gear or the driving gear set is set to be m 1 Setting the transmission ratio of the second driving gear 14 to the rotary table 15 to m 2 Setting the radius of the contact surface of the driving wheel of the first group of rotating wheels 2 as r 2 And the number of the rotating turns of the driving motor 1 in unit time is p, and the running distance of the watering cart in unit time is 2 pi x r 2 *p*m 1 The transmission ratio of the second driving gear 14 to the rotating disk 15 is m 2 The radian of rotation of the cylindrical surface (32) per unit time is 2 pi R m 2 And is and
2π*r2*p*m 1 ＝2π*R*p*m 2 that is, when the first drive gear 12 rotates one revolution, the drive gear or the drive gear set rotates 1/m 1 The arc length of the running of the driving wheel of the first group of rotating wheels 2 is 2 pi r 2 /m 1 Since the second driving gear 14 drives the rotary table 15 to rotate through the chain or the belt pulley, when the second driving gear 14 rotates for one circle, the rotary table 15 rotates for 1/m 2 The ring and the rotary disc 15 are fixedly connected with the rotating shaft 31, and the rotating shaft 31 rotates 1/m 2 The ring, and thus the cylindrical surface 32, rotates by 1/m 2 The ring, cylinder surface 32 rotates 1/m 2 Arc length L of loop movement 1 ＝2πR/m 2 And, 2 π R/m 2 The minimum pipe releasing speed and the minimum pipe receiving speed of the cylindrical surface 32 are required, so that the pipe releasing speed and the pipe receiving speed of the hose storage device 3 do not influence the operation of the watering cart, and the requirement of 2 pi R/m is only required 2 ＝2πr 2 /m 1 The pipe placing speed and the pipe receiving speed of the hose storage device 3 can not influence the running of the watering cart. The difference between the speed of the hose storage device 3 for storing and releasing the hose and the speed of the watering cart is the thickness of the nth layer of hose wound into the storage groove of the hose storage device 3, that is, nr 1 N.gtoreq.1, so to reduce this error, the width of the cylindrical surface 32 of the hose storage device 3 is increased as much as possible to wind the hose in each layer as many turns as possible.
In this embodiment, because the radius R of drum face 32 is greater than the runner of first group runner 2, the arc length that drum face 32 rotated the round and walked is far greater than the distance that first group runner 2 rotated the round and walked, so the angular velocity of driving motor 1 output should give first group runner 2 after accelerating with higher speed, give drum face 32 after decelerating simultaneously and just can guarantee that the travelling speed of first group runner 2 drive watering car is unanimous basically with putting the pipe and receiving the pipe speed assurance of hose storage device 3, the travelling distance of watering car and hose storage device 3 put the pipe length error and just lie in the hose winding multilayer back, rotate the influence of round hose thickness to drum face 32 effective radius.
