Description

Technical Field

[0001] The utility model relates to the field of coating agent medicines, in particular to a continuous supply device for seed coating agent. Background Art

[0002] Seed coating is the process of compounding pesticides, fungicides, micro-fertilizers, plant growth regulators, etc. through a scientific formula, adding an appropriate amount of solvent to form a paste, and then using a machine to evenly stir it and apply it to the seeds to form a coating. When in use, the above components need to be mixed and stirred before use. Small-scale coating agents are usually manually mixed and poured into the seeds. Large-scale and long-term seed coating requires the coating agent to be stirred in advance and discharged into the nozzle through a pump for use. Stirring and supply are carried out separately, which reduces efficiency and cannot be supplied continuously. Utility Model Content

[0013] The utility model is further described below in conjunction with the accompanying drawings:

[0014] like Figure 1 As shown, a seed coating agent continuous supply device is composed of a base frame 1, a stirring temporary storage box 2 and a continuous supply column cavity box 3;

[0015] The stirring temporary storage box 2 and the continuous supply column chamber box 3 are fixedly installed on the bottom frame 1. A partition layer 4 is fixedly installed in the stirring temporary storage box 2. The partition layer 4 divides the stirring temporary storage box 2 into an upper stirring chamber and a lower temporary storage chamber. A temporary storage valve 13 is installed on the partition layer 4 to facilitate the storage of the stirred seed coating agent in the temporary storage chamber for continuous supply.

[0016] A three-way valve 19 is installed at the bottom of the side box wall of the stirring temporary storage box 2. The two valve ports of the three-way valve 19 are connected to the side box wall of the continuous supply column chamber box 3 through a valve branch pipe 21, specifically connected to the upper and lower sides of the side box wall. Check valves 15 are installed on the upper and lower side box walls of the column chamber box 3. The two check valves 15 are connected together through a valve connecting pipe 16. The pipe body of the valve connecting pipe 16 is connected to a continuous supply pipe 17.

[0017] A lifting plug 18 is provided in the cavity plug of the column cavity box 3 for continuous supply, and a forward and reverse screw 14 is screwed at the center of the lifting plug 18. A transmission box 10 is fixedly installed on the top of the stirring temporary storage box 2. The top end of the forward and reverse screw 14 extends into the transmission box 10 and is connected and installed with a dual-purpose forward and reverse motor 11. A transmission wheel 12 is fixedly mounted on the forward and reverse screw 14 in the transmission box 10. A stirrer 7 is provided in the stirring cavity. The top end of the stirring shaft of the stirrer 7 extends into the transmission box 10 and is fixedly installed with a stirring wheel 8. The stirring wheel 8 is connected to the transmission wheel 12 through a stirring belt 9.
