Description

Technical Field

[0001] The utility model relates to the technical field of agricultural tools, in particular to a device capable of evenly spraying pesticides. Background Art

[0002] In agricultural plant protection machinery, the nozzle is an important component, and its function is to spray liquid pesticides evenly onto crops. Traditional pesticide nozzles usually adopt a single-hole or multi-hole design, and control the spray effect by adjusting the pressure and flow. With the development of agricultural science and technology, new pesticide nozzle technologies continue to emerge. For example, micro-spray technology can accurately control the spray volume and reduce the use of pesticides. Rotary nozzles can achieve 360-degree spraying without dead angles and improve spray efficiency. Ultrasonic nozzles use high-frequency vibration to produce micron-level atomized particles to improve spray uniformity and adhesion. This can not only improve the utilization rate of pesticides and reduce production costs, but also help reduce environmental pollution and protect ecological balance.

[0003] The prior art also has the following defects during use:

[0004] The pesticide uniform spraying device in the prior art sprays unevenly. When the pesticide is not completely dissolved in water, the pesticide particles that enter the nozzle will remain in the nozzle, making the traditional pesticide nozzle easy to be blocked and having a short service life.

[0005] In view of this, we propose a pesticide uniform spraying device to solve the existing problems. Utility Model Content

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] The utility model installs a water dividing ring inside the shell, and the medicine sprayed by the spiral tube can drive the water dividing ring to rotate. The water dividing ring cooperates with the water discharge hole at the bottom of the shell, so that the medicine inside the shell is sprayed intermittently, thereby achieving the purpose of pressurizing the medicine.

[0024] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0025] like Figure 1-5 As shown, the utility model proposes a pesticide uniform spraying device, comprising a shell 1, a connector 2, a threaded head 3 and a water dividing ring 4. A water discharge hole 102 is provided on one side of the bottom of the shell 1, and the water discharge hole 102 is semicircular. Several groups of spiral tubes 101 are fixedly installed inside the shell 1. The shell 1 can provide installation positions for surrounding components. The water discharge hole 102 can allow the internal medicine to enter the interior of the spherical cover 202 from the shell 1. The spiral tube 101 can guide the medicine so that the medicine flows downward in a spiral shape, and then the medicine is used to drive the water dividing ring 4 to rotate;

[0026] A threaded head 3 is welded on the top of the shell 1, and a connecting seat 301 is fixedly installed inside the threaded head 3. A plurality of water inlet holes are opened inside the connecting seat 301, and the water inlet holes are fixedly connected to the top of the spiral tube 101. The threaded head 3 can facilitate the installation of the device, so that the device can be quickly connected to the pesticide spraying equipment. The connecting seat 301 can be connected to the top of the spiral tube 101. On the one hand, the top of the spiral tube 101 can be limited and fixed, and on the other hand, the medicine inside the threaded head 3 can be guided into the inside of the spiral tube 101 to prevent the medicine from bypassing the spiral tube 101 and directly entering the inside of the shell 1;

[0027] A water-dividing ring 4 is rotatably installed at the bottom of the shell 1, a through hole 403 is opened on one side of the inside of the water-dividing ring 4, and a plurality of guide plates 402 are fixedly installed in a circular array on the top of the water-dividing ring 4 away from the through hole 403. The water-dividing ring 4 can be driven to rotate by the medicine sprayed from the spiral tube 101, and then the medicine is intermittently injected into the spherical cover 202 and sprayed out in cooperation with the lower water hole 102, so that the medicine inside the shell 1 is pressurized by the water hammer effect, and the spraying speed of the medicine is increased. The through hole 403 can make the medicine at the top of the water-dividing ring 4 flow into the spherical cover 202, and the guide plate 402 can increase the thrust received by the water-dividing ring 4, thereby improving the effect of the medicine at the bottom of the spiral tube 101 pushing the water-dividing ring 4 to rotate;

[0028] A connector 2 is welded to the bottom of the shell 1, a circular hole is opened inside the connector 2, a spherical cover 202 is welded to the bottom of the connector 2, a plurality of groups of injection holes 201 are opened inside the spherical cover 202, the connector 2 can fix the spherical cover 202 to the shell 1, the circular hole can allow the agent to pass through and then enter the interior of the spherical cover 202, the spherical cover 202 can guide the agent to spray out, which can not only improve the uniformity of the agent spraying, but also expand the agent spraying area and improve the efficiency of pesticide spraying.

[0029] Furthermore, rubber rings 401 are fixedly installed at equal intervals on the outside of the water-dividing ring 4, and the rubber ring 401 is in contact with the inner wall of the shell 1. The rubber ring 401 can improve the sealing between the water-dividing ring 4 and the inner wall of the shell 1, and prevent the medicine from flowing through the gap between the water-dividing ring 4 and the shell 1 without affecting the rotation of the water-dividing ring 4, thereby guiding the medicine on the top of the water-dividing ring 4 to flow into the spherical cover 202 through the through hole 403.

[0030] Furthermore, a circular groove is provided at the top of the threaded head 3, and a sealing ring 302 is clamped and installed inside the circular groove. The sealing ring 302 can improve the sealing performance at the connection position between the threaded head 3 and the pesticide spraying equipment, thereby avoiding leakage at the joint of the threaded head 3.

[0031] Furthermore, the bottom end of the spiral tube 101 is arranged obliquely downward, and the bottom end of the spiral tube 101 maintains a distance of one to two centimeters from the top of the water-dividing ring 4. The spiral tube 101 maintains a distance of one to two centimeters from the water-dividing ring 4, so that the agent sprayed by the spiral tube 101 pushes the water-dividing ring 4 to rotate at a uniform speed. The circulation of the agent is controlled by the rotation of the water-dividing ring 4, so that the agent is intermittently sprayed after being pressurized, thereby improving the spraying effect of the device on pesticides.

[0032] Furthermore, a rotating shaft is fixedly installed at the bottom of the water dividing ring 4, and the rotating shaft is rotatably connected to the bottom inside the shell 1. The rotating shaft can limit the bottom of the water dividing ring 4, thereby ensuring the stability of the water dividing ring 4 during rotation.

[0033] Working principle: after aligning the internal thread of the threaded head 3 with the external thread of the pesticide spraying equipment, rotate the device and tighten it, and install the device as a whole on the pesticide spraying equipment. The agent enters the spiral tube 101 through the threaded head 3, and the spiral tube 101 guides the agent to be sprayed out in a spiral shape. The agent sprayed from the spiral tube 101 pushes the water dividing ring 4 to rotate. The water dividing ring 4 rotates at a uniform speed under the push of the agent. The through hole 403 inside the water dividing ring 4 is intermittently connected with the drain hole 102 at the bottom of the shell 1, so that the agent accumulated inside the shell 1 is intermittently sprayed into the inside of the spherical cover 202. After the agent is guided by the spherical cover 202, it is quickly sprayed out from the inside of the spherical cover 202 by the water hammer effect formed by the thrust applied by the subsequent agent, thereby realizing pesticide spraying on crops or soil.

[0034] The above-mentioned specific embodiments are only several preferred embodiments of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above-mentioned embodiments, those skilled in the art can make various alternative improvements and combinations to the above-mentioned specific embodiments.
