[0001] The utility model relates to the technical field of pesticide proportioning, in particular to a liquid pesticide proportioning device. Background Art

[0002] Pesticides refer to chemical and biological drugs used to control harmful organisms that endanger agricultural, forestry and animal husbandry production. Normally, the concentrations of chemical and biological drugs just leaving the factory are relatively high. When used, the pesticides leaving the factory will be diluted and proportioned according to the actual crop scale requirements.

[0003] The existing Chinese patent application number 201620688391.5 discloses a liquid pesticide proportioner, including a medicine pot with a scale and an open top and a liquid pot, the medicine pot is provided with a medicine outlet pipe for discharging the internal liquid pesticide, the liquid pot is correspondingly provided with a connecting pipe matching therewith, the medicine outlet pipe / connecting pipe or between the two is provided with a control switch for connecting or cutting off the flow of liquid between the two, so that the liquid pesticide can be accurately configured without a measuring cup and a drainage tool.

[0004] However, the liquid pesticide proportioner still has some shortcomings in actual use. For example, each time the proportioning of the pesticide is performed, only one pesticide can be introduced into the liquid pot at a time, and different pesticides need to be repeatedly introduced into the pot, which is a cumbersome step. In addition, since no injection accessories are provided, each time the pesticide is proportioned, only the entire dosage of the pesticide in the pot can be introduced into the liquid pot, so that only a single proportioning can be performed. The next proportioning needs to be poured into the pot again, which is not practical and has a low proportioning efficiency. Utility Model Content

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] The utility model provides a technical solution: comprising a proportioning component 1, wherein the top of the proportioning component 1 is threadedly connected with three dispensing components 2, the proportioning component 1 comprises a proportioning pot 101, a motor cavity 102 is provided at the bottom of the proportioning pot 101, a proportioning cavity 103 is provided in the proportioning pot 101 and above the motor cavity 102, and three threaded joints 106 are provided on the top surface of the proportioning pot 101;

[0021] The dispensing component 2 includes a dosing tube 201, a dosing chamber 202 is provided in the dosing tube 201, a threaded head 203 is fixedly installed at the bottom of the dosing tube 201, a piston 204 is movably installed in the dosing chamber 202, a moving screw 205 is rotatably installed at the center of the top surface of the piston 204, a flat plate 206 is fixedly installed on the top of the dosing tube 201, a slot 207 is provided at the rear of the top surface of the flat plate 206, and both ends of the slot 207 are slidably installed. There is a clamping plate 208, and a semi-threaded opening 209 is opened in the middle of the opposite surfaces of the two clamping plates 208. The two semi-threaded openings 209 can together form a complete threaded opening. The movable screw 205 is threadedly inserted in the threaded opening. The front of the plate 206 is opened with a slide groove 210, and an adjusting screw 211 is rotatably installed in the slide groove 210. A threaded block 212 is slidably installed on both sides of the slide groove 210, and the threaded block 212 is threadedly sleeved on both ends of the adjusting screw 211.

[0022] In this embodiment, a partition is provided between the motor cavity 102 and the proportioning cavity 103 , and a rotating motor 104 is fixedly installed at the center of the inner bottom surface of the motor cavity 102 .

[0023] At the same time, the two threaded blocks 212 correspond to the two clamps 208 one by one, and the threaded blocks 212 are fixedly connected to the clamps 208. One end of the adjusting screw 211 extends to the outside of one side of the flat plate 206, and a knob is fixedly installed at the extended end, which can conveniently control the merging and separation of the two clamps 208, and then control the separation and merging of the two semi-threaded openings 209. Therefore, when extracting the medicine, you only need to simply lift the abutting screw 205. When injecting, the medicine can be injected accurately and slowly.

[0024] The three threaded heads 203 correspond to the three threaded connectors 106 one by one. The threaded heads 203 are threadedly inserted into the threaded connectors 106. The rotating motor 104 is started, and the stirring head 105 can be driven to rotate by the rotating motor 104. The rotation of the stirring head 105 can accelerate the mixing of the medicine.

[0025] One end of the output shaft of the rotating motor 104 passes through the partition and is fixedly mounted with a stirring head 105 , and a spout 107 is fixedly mounted at the bottom of the front side of the mixing pot 101 .

[0026] During use, when it is necessary to perform proportioning, several dispensing components 2 are selected and activated according to the type of medicine to be proportioned this time. When using the dispensing component 2, the threaded head 203 is unscrewed from the opening of the threaded joint 106. After unscrewing, the adjusting screw 211 is rotated. Since the adjusting screw 211 is a double-headed threaded rod, the textures at both ends are opposite. Therefore, the rotation of the adjusting screw 211 drives the two threaded blocks 212 threadedly sleeved thereon to move to both sides respectively. The movement of the two threaded blocks 212 can drive the two clamping plates 208 to separate. After the two clamping plates 208 are separated, the threaded head 203 can be inserted into the proportioning medicine, and then the adjusting screw 211 is manually pulled. By pulling the adjusting screw 211, the piston 204 can be driven to move in the medicine adding chamber 202, so that the medicine can be sucked into the medicine adding chamber 202. After a certain dose is inhaled, the adjusting screw 211 is rotated at this time. The rotation of the adjusting screw 211 can drive the two clamping plates 208 to merge Together, and then merge the two half-threaded openings 209 together. After merging, re-thread the threaded head 203 and the threaded connector 106, repeat the above operation to suck other agents into the corresponding dosing chamber 202, and then introduce the agents in each dosing chamber 202 into the mixing pot 101 according to the various data of the pesticide to be proportioned. The specific introduction steps are as follows: first, rotate the abutting screw 205. Since the abutting screw 205 is threadedly connected to the entire threaded opening, as the abutting screw 205 rotates, the abutting screw 205 will rise and fall accordingly. By controlling the abutting screw 205 to descend, the piston 204 can be driven to descend, so that the agent can be injected into the mixing chamber 103 for proportioning. After each proportioned agent is injected into the mixing pot 101, start the rotating motor 104. The rotation of the rotating motor 104 can drive the stirring head 105 to rotate, and the rotation of the stirring head 105 can accelerate the mixing of the agents.

[0027] To summarize, the liquid pesticide proportioner can absorb three different pesticide agents at one time by setting up three dispensing components, and the proportioning personnel do not need to repeat the medicine taking steps. At the same time, by controlling the rotation of the adjusting screw, the piston can be slowly and steadily pushed to move in the dosing chamber, and then the required dosage can be stably injected into the proportioning chamber, which can not only improve the proportioning accuracy, but also the remaining agent in the dosing chamber can provide agent for the next proportioning, thereby realizing multiple pesticide proportioning operations, and thus effectively improving the practicality of the proportioner.
