Embodiment 1

[0028] Such as figure 1 As shown, the fertilization equipment with variable volume is composed of a perfusion tube 1, a piston 2, a piston rod 3, a retaining ring 4, a sealing plate 5, a spring 6, a support body 7, a liquid storage tank 8 and a sliding fixed body 11; the perfusion tube 1 is a hollow structure, the bottom of the perfusion tube 1 is pointed, and a liquid outlet hole 102 is opened on the outer surface of the bottom of the perfusion tube 1; the support body 7 is fixed in the perfusion tube 1, and multiple passage holes are opened on the support body 7 71; the retaining ring 4 is fixed in the perfusion pipe 1, and the retaining ring 4 is located above the support body 7; the sealing sheet 5 is arranged in the perfusion pipe 1, and the sealing sheet 5 is located between the support body 7 and the retaining ring 4, and the sealing sheet 5 and the perfusion There is a gap between the inner surfaces of the tube 1; the spring 6 is arranged in the perfusion tube 1, one e...

Embodiment 2

[0035] Such as figure 1 As shown, this embodiment is based on Embodiment 1, the bottom of the retaining ring 4 is provided with a locking groove 41 ; the top of the sealing sheet 5 is provided with a snap ring 51 corresponding to the locking groove 41 .

[0036] The snap ring 51 and the snap groove 41 are provided to avoid misalignment of the retaining ring 4 and the sealing sheet 5 and improve the sealing performance.

Embodiment 3

[0038] Such as figure 1 As shown, on the basis of Embodiment 1, this embodiment further includes a one-way valve 9 disposed in the flow hole B101 , and the one-way valve 9 leads into the perfusion tube 1 .

[0039] A one-way valve 9 is set to prevent the liquid fertilizer from flowing back into the liquid storage tank 8 when the piston 2 is pressed down.

Abstract

The invention discloses application volume variable fertilizing equipment. A filling pipe is of a hollow structure, the bottom of the filling pipe is a pointed end, and a liquid outlet is formed in the outer circumferential surface of the bottom of the filling pipe; a supporting body is fixedly arranged in the filling pipe, and multiple through holes are formed in the supporting body; a retaining collar is fixedly arranged in the filling pipe; a sealing piece is arranged in the filling pipe, and a gap is formed between the sealing piece and the inner surface of the filling pipe; one end of a spring is connected with the sealing piece, and the other end of the spring is connected with the supporting body; a piston is positioned above the retaining collar; a sliding fixed body is fixedly arranged in the filling pipe in a sliding manner through a sliding chute in the inner surface of the filling pipe; an external thread is formed on the outer surface of a piston rod, the piston rod is in threaded fit with a threaded hole in the sliding fixed body, one end of the piston rod is connected with the upper surface of the piston, and the other end of the piston rod extends out of the filling pipe; a liquid storage tank is fixedly arranged on the outer surface of the filling pipe; the equipment further comprises an ascending pipe. According to the equipment, subsoil fertilization is realized, and the amount of fertilizer applied at one time can also be regulated.

Description

technical field [0001] The invention relates to an agricultural implement. Background technique [0002] When the soil cannot provide the nutrients needed for crop growth and development, it is necessary to supplement the crops with artificial nutrients. Typically, when crops are supplemented with nutrients, fertilizers are applied directly to the soil at the roots of the crops. Such a fertilization method makes it difficult for the roots of the crops to directly absorb the fertilizer, resulting in low absorption efficiency and a long absorption cycle. Contents of the invention [0003] The object of the present invention is to overcome the deficiencies of the prior art and provide a fertilization device with variable application volume. [0004] The object of the present invention is achieved through the following technical solutions: [0005] Fertilization equipment with variable volume, including perfusion pipe, piston, piston rod, retaining ring, sealing plate, spri...
