Detailed Description

The invention is further described below with reference to the accompanying drawings:

the first embodiment is as follows:

as shown in fig. 1, the present embodiment comprises a reel 1 and a trolley 2, the reel 1 is mounted on the trolley 2 by means of two stub shafts 9 fixed to the center of the reel 1, and a water pipe 3 is wound around the reel 1. The above is a common structure in the prior art, and is not described herein again.

As shown in figure 1, the reel 1 structurally comprises two circular plates 7, an inner cylinder 6 and an outer cylinder 4, wherein the circular plates 7 are arranged in total, the inner cylinder 6 is positioned on the inner side of the outer cylinder 4 and is coaxial with the outer cylinder 4, the two circular plates 7 are welded on the side surfaces of the inner cylinder 6 and the outer cylinder 4, and the space on the inner side of the inner cylinder 6 is a fertilizer storage chamber. The fertilizer storage chamber is arranged inside the reel 1, so that the space can be effectively saved, and the structure of the equipment is more compact.

As shown in fig. 1, a helical blade 5 is arranged in an annular space between an inner cylinder 6 and an outer cylinder 4, the helical blade 5, the inner cylinder 6 and the outer cylinder 4 together enclose a helical flow passage 15, a liquid passing hole 8 is arranged at the center of one short shaft 9, one end of the water pipe 3 is communicated with one end of the helical flow passage 15, and the other end of the helical flow passage 15 is communicated with the liquid passing hole 8 through a connecting pipe 10. When the water-saving device is used, a water source is connected to the short shaft 9 with the liquid passing hole 8, and water flows out after passing through the connecting pipe 10, the spiral flow passage 15 and the water pipe 3. Here, the spiral flow path 15 has two functions: on one hand, after the peristaltic pump 12 pumps the liquid fertilizer into the spiral flow channel 15, the liquid fertilizer and the water can be uniformly and fully mixed through the flow in the spiral flow channel 15, so that the concentration stability of the liquid fertilizer in the irrigation water is ensured; on the other hand, in practical use, the diameter of the reel can reach two meters, the weight of the reel is very large, and therefore the force required for rotating the reel 1 when the water pipe 3 is wound and unwound is also very large, in the invention, the axis of the spiral flow passage 15 is overlapped with the axis of the reel 1, and the water in the spiral flow passage 15 is uniformly distributed around the reel 1 to play a role of balance weight, so that the gravity distribution of the reel 1 is more uniform, and the rotation of the rotary table 1 is more labor-saving.

As shown in figure 1, in order to mix the liquid fertilizer in the fertilizer storage chamber into water, the invention arranges a peristaltic pump 12 in the reel 1, the peristaltic pump 12 is a common type of pump type equipment, the peristaltic pump 12 is like a hose filled with fluid which is squeezed by fingers, and the fluid in the hose moves forwards along with the fingers sliding forwards. The peristaltic pump 12 is also a principle that only the finger is replaced by a roller. The fluid is pumped by alternately squeezing and releasing the elastic delivery hose of the pump. Just like squeezing the hose with two fingers, as the fingers move, negative pressure is formed in the hose, and the liquid flows along with the negative pressure. The advantages of the peristaltic pump 12 are: the fluid is isolated in the hose, the hose can be quickly replaced, the fluid can move reversely, the dry running can be realized, and the maintenance cost is low. In addition, the peristaltic pump is adopted to pump the liquid fertilizer, so that the control precision of the fertilizing amount is high, and the fertilizing effect is favorably improved.

As shown in figure 1, in the invention, a round hole is arranged on the side surface of the reel 1, a peristaltic pump 12 is inserted into the round hole, a liquid inlet pipe 13 of the peristaltic pump 12 is communicated with the space in the fertilizer storage chamber, and a liquid outlet pipe 11 of the peristaltic pump 12 is communicated with the spiral flow channel 15. This cartridge configuration facilitates servicing and replacement of the peristaltic pump 12.

As a further technical scheme, the tail end of the liquid inlet pipe 13 is provided with a gravity ball 14, and the gravity ball 14 can enable a liquid inlet of the liquid inlet pipe 13 to be always positioned below the liquid level of the liquid fertilizer in the rotation process of the reel 1, so that the pumping effect of the peristaltic pump 12 on the liquid fertilizer is ensured.

As a further technical solution, the peristaltic pump 12 is fixed on the reel 1 by a quick snap, which is beneficial to quick detachment of the peristaltic pump 12.

As a further technical solution, the peristaltic pump 12 is driven by an accumulator.

Example two:

alternatively, the manner in which peristaltic pump 12 is driven may be modified. As shown in fig. 3 and 4, in the present embodiment, the structure of the peristaltic pump 12 includes an impeller 16, a drive shaft 17 and a pump head 18, wherein the drive shaft 17 and the pump head 18 are essential structures existing in all the peristaltic pumps 12, and are not described in detail herein. The present embodiment features the use of an impeller 16 in place of the motor in the prior art peristaltic pump 12. In the first embodiment, when the peristaltic pump 12 adopts the storage battery for power supply, the rotating speed of the pump cannot be adjusted, and when the water flow connected in the water pipe 3 changes, the pumping speed of the liquid fertilizer is still unchanged, so that the concentration of the fertilizer liquid fluctuates, the fertilizing effect is influenced slightly, and the nursery stock is damaged seriously. In addition, when the present invention is used to spray pesticides, the damage to the nursery stock can be devastating. In order to solve the problem, in the embodiment, the water is introduced to the impeller 16 through the connecting pipe 10, the water flows through the impeller 16 and then enters the spiral flow channel 15, the rotating speed of the impeller 16 changes along with the change of the water flow, namely, the amount of the liquid fertilizer mixed into the water and the water flow change synchronously, so that the concentration of the liquid fertilizer in the water is always kept stable, and finally, the adverse effect caused by the concentration fluctuation of the fertilizer liquid is eliminated.
