Description

Technical Field

[0001] The utility model relates to the field of seed treatment agent equipment, in particular to a liquid material supply and distribution device and equipment thereof. Background Art

[0002] Seed treatment agents are used for seed dressing during the seed sowing period. Seed treatment agents include seed dressing agents, seed mixing agents and seed soaking agents. Seed mixing agents are diluted in a certain proportion before sowing and evenly mixed with seeds. The seeds absorb the seed treatment agents and play a role in preventing and controlling diseases and insect pests when the seeds are sown and germinated. Seed treatment agents can prevent seeds from carrying pathogens, and at the same time prevent seeds from being hindered by diseases and insect pests during the germination and growth of seedlings after sowing. The current existing seed treatment methods are to add seed treatment agents manually in proportion. There are large operating errors and inaccurate dosage addition problems during the treatment process, especially when different agents are added in proportion, the addition amount has poor accuracy. Therefore, this method has the following defects: 1. It is not suitable for the treatment of large quantities of seeds, but only suitable for small quantities. The large-scale treatment process is time-consuming and labor-intensive; 2. There are large errors in the operation process of manually adding seed treatment agents, and the amount added is difficult to control. Too much addition will damage the seeds, and too little addition will not have an ideal preventive protection effect on the seeds. Utility Model Content

[0007] Furthermore, a third valve is provided on the feeding pipe, and a second vacuum conveyor is provided at the lower end of the weigher. Preferably, the second vacuum conveyor forms negative pressure around it through the high-speed flow of compressed air, thereby taking away the raw materials, thereby improving the conveying efficiency of the materials.

[0008] Furthermore, the first vacuum conveyor and the second vacuum conveyor are both connected to a compressed air conveying pipe.

[0009] Furthermore, the compressed air is delivered to a first air pipe and a second air pipe, the air delivery speed of the first air pipe is greater than the air delivery speed of the second air pipe, and the first air pipe and the second air pipe are connected to the first vacuum conveyor through a tee. The delivery speed of the raw material is achieved through the first air pipe and the second air pipe, thereby ensuring the accuracy of the raw material addition and avoiding excessive addition of the raw material due to inertia.

[0010] Furthermore, the feed port of the feed pipe extends toward the bottom of the raw material tank, thereby ensuring a continuous supply of raw materials and avoiding a supply interruption of the raw materials or a large amount of residue at the bottom of the raw material tank.

Each liquid material supply and dispersing device provides different raw materials or auxiliary materials. After the preparation is completed, they can be directly used to treat seeds, or diluted with water before treatment, so as to ensure the effect of the seed treatment agent. In addition, it can also reduce the volatilization of the seed treatment agent during transportation and storage, reduce the cost of packaging and transportation, and reduce the cost of seed treatment.

[0013] Furthermore, it also includes a controller for controlling the entire device.

[0014] Furthermore, the raw material tank comprises a water storage barrel, and the water storage barrel is provided with a water inlet pipe and a liquid level meter.

[0015] The utility model has the following characteristics: by arranging a plurality of liquid material supply and dispersing devices, it is possible to realize the automatic addition and configuration of different seed treatment agents according to a proportion that is accurate, and the agents can be directly used to treat seeds or be treated after dilution, thereby reducing the packaging and transportation costs of the finished seed treatment agent; a disperser is arranged at the discharge end of the feeding pipe, which reduces the impact on the weighing device during the discharge of the raw materials, prevents the raw materials from splashing and affecting the weighing accuracy of the weighing device, and reduces the amplitude of the raw material swing.
