Problems solved by technology

[0003] In the existing diaphragm pumps, the crank slider mechanism is generally used to drive the reciprocating movement of the diaphragm. The crank slider mechanism and the diaphragm are connected by hinges. The force state is more complex and the life is shorter
In addition, the diaphragm is generally directly connected to the diaphragm support. When the diaphragm moves to make the diaphragm cavity smaller and the pesticide in the diaphragm cavity is discharged, due to the pressure of the diaphragm cavity, the diaphragm cannot be completely lifted up, and the volume of the diaphragm cavity changes small. Displacement

Embodiment 1

[0067] Combine Figure 1 to 5 In the embodiment of the present invention, a diaphragm pump may include a pump body 1, a pump cover 8, a diaphragm 3, a drive mechanism 4, and a diaphragm support 5. Wherein, the pump cover 8 is provided on the pump body 1, and the separator sheet 3 is provided in the pump body 1. The diaphragm 3 of the present embodiment is fitted to the pump cover 8, in particular, the separator sheet 3 is surrounded by the pump cover 8 to form a cavity. The drive mechanism 4 is connected to the diaphragm 3. In this embodiment, the drive mechanism 4 is directly or indirectly connected to the side of the diaphragm 3 away from the cavity, and the drive mechanism 4 is used to drive the diaphragm 3 relative to the pump cover 8 reciprocating motion, so that the cavity The body is reduced or increased. When the drive mechanism 4 drives the diaphragm 3 toward the pump cover 8, when the drive mechanism 4 is pressed, the diaphragm is reduced, and the pesticide within the cav...

Embodiment 2

[0191] See Figure 23 The second embodiment of the present invention provides an agricultural plant protection machine, including a rack 100, a reservoir 200 for storing the liquid liquid, a conduit 300, a plurality of nozzle 400, and a diaphragm pump in communication with the reservoir 200. Among them, the diaphragm pump can pump the pesticide to the spray head 400 from the reservoir 200, and spray the liquid solution to the crop by the nozzle 400.

[0192] The agricultural plant protection machine of this embodiment can be a plant protection drone or a pesticide spraying car or a human spray device.

[0193] Optionally, the diaphragm pump is the diaphragm pump 520 of the above-described embodiment. In the present embodiment, the inlet 11 of the diaphragm pump 520 communicates with the reservoir 200 through the conduit 300, and the liquid opening 12 communicates with the nozzle 400 through the pipe 300. The diaphragm pump 520 pumps the pesticide to the nozzle 400 from the reservoi...

Abstract

A diaphragm pump for an agricultural plant protection machine and the agricultural plant protection machine, the diaphragm pump (520) includes a pump body (1), a pump cover (8) mounted on the pump body (1), a pump cover (8) mounted on the pump body (1) The inner diaphragm (3) is connected with the driving mechanism (4) and the diaphragm support (5), and the diaphragm (3) is matched with the pump cover (8) so that the diaphragm (3) and the pump The cover (8) surrounds and forms a cavity, one end of the diaphragm support (5) abuts against the side of the diaphragm (3) away from the pump cover (8), the other end is connected to the driving structure (4), the diaphragm support (5) and the diaphragm The contact area of ​​the sheet (3) away from the pump cover (8) is larger than the preset area threshold; the driving mechanism (4) drives the diaphragm (3) to reciprocate relative to the pump cover (8), so that the cavity decreases or increases. By setting the diaphragm support (5), the diaphragm (3) reciprocates along the same direction, while reducing the movement of the diaphragm (3) in other directions, improving the force condition of the diaphragm (3), and extending the diaphragm (3) service life, and ensure that the pesticide in the cavity can be completely discharged.

Description

Technical field [0001] The present invention relates to the field of pumps, in particular to diaphragm pumps and agricultural plant protection machines for agricultural plant protection machines. Background technique [0002] Agricultural plant protection machine is used to achieve spray operations, which can spray pesticides. Most of the pumps are currently driven to drive agricultural plant protection machines to achieve spray operations. Due to the strong corrosion resistance of pesticides, the pump needs to have certain corrosion resistance, so on the agricultural plant protection machine, the diaphragm is usually pumped to the sprinkler. The diaphragm pump is a volume change of the diaphragm cavity by reciprocating motion of the diaphragm, thereby pumping the pesticide pumping out. [0003] In the existing diaphragm pump, the crank slider mechanism is generally used to drive the reciprocating motion of the diaphragm, the crank slider mechanism and the separator are connected...
