Description

liquid fertilizer dispenser liquid fertilizer dispenser

technical field

The invention belongs to agricultural machinery, and mainly relates to an operation assembly on a liquid fertilizer applicator.

Background technique

In order to improve the use efficiency of chemical fertilizers, liquid fertilizer fertilization technology has been advocated and popularized in agricultural production in recent years. However, since liquid fertilization requires quantitative and accurate injection of liquid fertilizer to the side of the root system of crops, especially the precise control of the amount of liquid fertilizer injected each time is very important, its technical difficulty is relatively high, and there is no ideal method at present. The application of liquid fertilizer fertilization equipment in production restricts the promotion of liquid fertilization agronomic technology.

Contents of the invention

The purpose of the present invention is to solve the problems in the above-mentioned prior art and combine the actual needs of agricultural production to design and provide a liquid fertilizer dispenser for a liquid fertilizer applicator to achieve the goals of accurate fertilizer injection, reliable use, and high automation.

The basic design of the present invention is that the housing is sequentially equipped with a liquid supply pipe, a liquid outlet pipe, a connecting frame and a rotating shaft; There is a liquid fertilizer output hole on the top, and the two ports of the liquid fertilizer output hole are respectively connected with the liquid supply pipe and the liquid outlet pipe; the tappet with the liquid fertilizer output communication hole is slidably arranged in the center hole of the valve sleeve and the locking sleeve. The liquid fertilizer output communication hole and the liquid fertilizer output hole cooperate with each other; a bushing is installed between the tappet and the valve sleeve; the pressure spring is set on the tappet and is located in the center hole of the locking sleeve, and the pressure regulating ring is fitted on the tappet through thread fit. on the column, and is in contact with one end surface of the pressure spring; the base can be adjusted axially on the end of the locking sleeve, and the tappet sleeve is installed on the end of the tappet; the cam is fixed on the shaft, The cam is in contact with the tappet bushing; a vent hole is arranged on the valve bushing so as to form a liquid fertilizer distributor for the liquid fertilizer applicator.

The invention has the advantages of simple structure, accurate and reliable action, high degree of self-control, precise liquid fertilization amount, wide application range and strong versatility, and can be assembled and used on various liquid fertilizers.

Detailed ways

The best embodiment of the present invention will be described in detail below in conjunction with the accompanying drawings. A liquid fertilizer dispenser for a liquid fertilizer applicator, the housing 1 is equipped with a liquid supply pipe 16, a liquid outlet pipe 14, a connecting frame 3 and a rotating shaft 11 in sequence; The sleeve 2 and the locking sleeve 5 are connected to each other as a whole, and are integrally installed on the connecting frame 3. The valve sleeve 2 is provided with a liquid fertilizer output hole 17, and the two ports of the liquid fertilizer output hole 17 are connected with the liquid supply pipe 16 and the liquid outlet respectively. The pipe 14 is relatively connected; the tappet 6 provided with the liquid fertilizer output communication hole 13 is slidably arranged in the center hole of the valve sleeve 2 and the locking sleeve 5, and the liquid fertilizer output communication hole 13 cooperates with the liquid fertilizer output hole 17; A bushing 4 is installed between the valve sleeve 2; the pressure spring 7 is set on the tappet 6 and is located in the center hole of the locking sleeve 5, and the pressure regulating ring 8 is fitted on the tappet 6 through thread fit, and is connected with the pressure spring 7. One end surface is in contact with each other; the base 9 can be axially adjusted on one end of the locking sleeve 5, and the tappet sleeve 10 is installed on the end of one side of the tappet 6; the cam 12 is fixed on the rotating shaft 11, The cam 12 is in contact with the tappet sleeve 10; the vent hole 15 is set on the valve sleeve 2.

When the operation is in use, the liquid fertilizer distributor is assembled on the liquid fertilization equipment, the liquid fertilizer pressure input device is communicated with the liquid supply pipe 16, the liquid outlet pipe 14 is communicated with the liquid fertilizer injection needle, and the rotating shaft 11 is connected with the power drive system. The rotary motion of the rotating shaft 11 drives the tappet 6 to continuously perform reciprocating linear motion in the center hole of the locking sleeve 5 and the bushing 4 through the cooperation of the cam 12, the pressure spring 7 and the pressure regulating ring 8, so that the liquid fertilizer output hole on the tappet 6 17 Continuously repeatedly connect or block the liquid supply pipe 16 and the liquid outlet pipe 14 to complete the quantitative and regular injection operation of liquid fertilizer. The vent hole 15 on the valve sleeve 2 eliminates the gas resistance phenomenon that the tappet 6 produces when it moves back and forth in a straight line, so as to ensure reliable operation and reduce the movement resistance of the tappet 6 .
