For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0027] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0028] A seed coating agent mixing device with quantitative discharging, such as Figure 1 , 2 The stirring tank 22 includes a feeding hopper 16 and a discharging assembly. The feeding hopper is arranged at the upper end of the side wall of the stirring tank, and a discharging port 21 is arranged at the bottom of the stirring tank.

[0029] The discharging assembly is arranged below the discharging port, and includes: a base 11, a discharging tray 7, a material cup 2 and a control rod 12. A discharging shaft 5 is vertically arranged on the base, and a discharging motor 10 is also arranged on the base. The discharging motor can drive the discharging shaft to rotate by meshing the bevel gear arranged on its transmission shaft with the bevel gear sleeved on the discharging shaft. The center of the discharging tray is fixedly connected to the discharging shaft, and the rotation of the discharging shaft can cause the discharging tray to rotate.

[0030] A cup groove 1 is provided on the discharge tray, the upper opening of the cup groove is flush with the top surface of the discharge tray, and a liftable tray 3 is provided in the cup groove; the material cup is detachably arranged on the tray, and a guide section is provided on the outer edge of the tray, which can guide and limit the material cup to the center of the tray when the material cup is placed in.

[0031] A guide rod 6 and a push rod 4 are provided on the bottom surface of the tray, and a first through hole 8 for accommodating the guide rod and a second through hole 9 for accommodating the push rod are provided on the bottom surface of the cup groove. The guide rod is slidably arranged in the first through hole and cooperates with the first through hole. The tray can be lifted and lowered in the cup groove under the guidance of the guide rod and the first through hole.

[0032] A receiving hole is provided on the base, and the control rod can be raised and lowered in the receiving hole. When the rotation of the discharging tray makes the cup groove and the discharging port relatively aligned, the second through hole will be relatively aligned with the receiving hole. At this time, the rising action of the control rod can make the top of the control rod insert into the second through hole, thereby locking the rotation of the discharging tray to prevent the discharging tray from rotating abnormally when the material enters the material cup. When the weight of the material in the material cup reaches the preset weight, the increase in the weight of the material cup can press down the tray so that the top rod at the bottom of the tray is inserted into the second through hole. The control rod can be lowered by the top rod against the control rod, and finally the top of the control rod can be withdrawn from the second through hole. When the control rod leaves the second through hole, the rotation lock of the discharging tray will be released. At this time, the discharging tray can rotate under the drive of the discharging motor and the discharging shaft, so that the material cup containing the preset weight of material leaves the discharging port, which is convenient for the staff to take.

[0033] It should be noted that the discharge motor in this embodiment should have a self-protection function to avoid the discharge motor from being stopped and damaged when the discharge tray is in a rotationally locked state.

[0034] The discharging assembly also includes a spring 13 and a latch 14. The spring is sleeved on the metering rod. The bottom of the spring is connected to the top surface of the base. The latch is arranged on the top of the spring. A plurality of grooves 15 for accommodating the latch are arranged on the metering rod, and the plurality of grooves are evenly arranged along the axis direction of the metering rod. When the latch is inserted into the groove of the metering rod, the spring can provide an upward elastic force for the metering rod through the latch. When the metering rod is aligned with the second through hole, the top of the metering rod can be inserted into the second through hole under the action of the elastic force. When the weight of the material in the material cup is greater than the elastic force of the spring, the push of the top rod against the metering rod can compress the spring, so that the metering rod moves downward and exits the second through hole.

[0035] When the latch is inserted into different grooves on the control rod, the initial length of the spring is different. Since the initial length of the spring will affect the elastic force generated by the compression of the spring, the staff can adjust the pressure of the control rod to trigger the descending action by adjusting the installation groove of the latch, and then change the timing of the discharging tray to rotate and unlock to adjust the preset weight in this embodiment. When the groove where the latch is inserted is closer to the top of the control rod, the initial length of the spring is longer, and the upward elastic force provided by the spring to the control rod is smaller, so that the weight of the material in the material cup that can be unlocked by the discharging tray is lighter, that is, the preset weight is lighter, and quantitative discharging of seed coating agents of different weights is realized, which is convenient for adapting to packaging of various specifications.

[0036] In order to improve the discharging efficiency of the device, two cup grooves can be provided on the discharging tray, and the two cup grooves should be symmetrically arranged on both sides of the center of the discharging tray. When working, the two cup grooves can alternately perform quantitative discharging and packaging, so that when one material cup is under the discharging port to receive the material, the other material cup can be taken out of the cup groove to package the material therein. Correspondingly, multiple cup grooves can also be provided. When multiple cup grooves are provided, the multiple cup grooves should be arranged in a ring shape on the discharging tray, and a tray and a material cup are provided inside each cup groove. By providing multiple cup grooves, the rotation interval of the discharging tray during operation can be shortened, thereby further improving the discharging efficiency of the device.

[0037] The stirring kettle is cylindrical, and the bottom surface of the stirring kettle is funnel-shaped. The discharge port is located at the bottom end of the funnel-shaped. A stirring motor 30 is arranged on the top surface of the stirring kettle. A feed port 17 is arranged on the upper end of the side wall of the stirring kettle, and the feed hopper is connected to the feed port. The stirring kettle is also provided with a rotatable stirring blade 20 and an auger 19. There are two stirring blades, and the lower edge of the stirring blade is a bevel and can match with the bottom surface of the stirring kettle. The stirring blade is also provided with a square hole 23, which can allow the material in the stirring kettle to pass through, so as to prevent the material from being greatly stirred by the stirring blade, that is, reducing the resistance of the stirring blade, saving energy, and also making the material in the stirring kettle be more fully mixed.

[0038] A channel for accommodating an auger is provided between the two stirring blades. The auger is provided in the channel and is located at the center of the stirring kettle. The lower end of the auger is located at the center of the funnel-shaped bottom surface of the stirring kettle. The auger shaft 25 extends upward, and the top end of the auger shaft extends above the top surface of the stirring kettle. The top end of the auger shaft is provided with an auger drive wheel 28. The upper edge of the stirring blade is connected to the stirring shaft 26 through a stirring rod 24. The stirring shaft sleeve is provided outside the auger shaft. The two stirring blades rotate around the auger, and the rotation direction of the stirring blade is opposite to that of the auger. The upper end of the stirring shaft is provided with a blade drive wheel 27.

[0039] The blade drive wheel and the auger drive wheel are both bevel gears, which are respectively meshed with the driving bevel gear 29 on the stirring motor drive shaft and driven by the stirring motor, thereby driving the stirring blade and the auger to rotate respectively. Since the blade drive wheel and the auger drive wheel are respectively meshed with the two sides of the bevel gear on the stirring motor drive shaft, the stirring blade and the auger rotate in opposite directions, and the auger can transport the material in the stirring kettle upward. After the material is transported to the upper end of the auger, it is freely scattered to the outside of the auger and stirred by the stirring blade. The stirring blade and the auger cooperate to fully mix the material in the stirring kettle.

[0040] A feed plate is provided in the mixing kettle above the mixing blade, one end of which is connected to the feed port, and a plurality of circular holes are arranged alternately on the feed plate. After the material enters from the feed port, it passes through the feed plate and can be evenly sprinkled in the mixing kettle through the plurality of circular holes during the process of sliding downward, so that the material in the mixing kettle is easier to be mixed evenly.

[0041] When producing seed coating agents, first pour the raw materials from the feed hopper into the stirring kettle, mix them evenly through the auger and stirring blades in the stirring kettle, and then discharge them from the discharge port. When the cup groove is aligned with the discharge port, the material in the stirring kettle can fall into the material cup under the action of gravity, and the upper opening of the cup groove can fit tightly with the discharge port to prevent the material from spilling out.

[0042] When the material in the material cup reaches the preset weight, the tray descends to make the push rod insert downward into the second through hole to push the top of the control rod out of the second through hole. At this time, the discharging tray rotates and unlocks. The discharging tray rotates under the drive of the discharging motor. The cup groove and the material cup filled with material gradually leave the discharging port. At this time, the discharging port is closed by the top surface of the discharging tray, and the material in the stirring kettle will not spill out. When the other set of cup grooves and material cups are rotated to align with the discharging port, due to the insufficient weight of the material in the material cup, the control rod is inserted into the second through hole aligned with it under the push of the spring to lock the rotation of the discharging tray. At this time, the material cup filled with material can be taken away by the operator to package the material in the material cup. After the material cup filled with material is taken away, the empty material cup should be replaced in time and put into the cup groove. When the material cup below the discharging port is filled with the preset weight of material, the discharging tray will rotate and unlock, and the empty material cup will continue to rotate to the bottom of the discharging port for quantitative discharging, and the discharging is carried out alternately in this way.

[0043] The effects of the above scheme are described below:

[0044] In the utility model, the control rod can be pushed out of the second through hole by the descending push rod only when the material in the material cup reaches a preset weight under the thrust provided by the spring and the latch, so that the material discharging plate can be rotated and unlocked, and the weight of each material discharging can be automatically limited, and the operator is no longer required to weigh it twice, thereby reducing the risk of contact with toxic substances; by adjusting the latch to be inserted into different grooves on the control rod, the initial length of the spring is changed, so that the thrust provided by the spring to the control rod is different, and the push rod can push the control rod out of the second through hole. The weight of the material in the material cup required is also different, thereby achieving quantitative discharging of different weights. The material can be adapted to the packaging needs of various materials and specifications; the top surface of the discharge tray can fit tightly with the discharge port, reducing the risk of material spilling; multiple cup slots and material cups can discharge materials alternately, and when one cup slot and material cup are aligned with the discharge port for discharging, other material cups can be taken out of the cup slot and the materials in the cups can be packaged, thus improving the packaging / packaging efficiency; the feed plate adopts a staggered porous structure, which makes the material spilling more evenly during feeding and is easy to stir; the auger transports the material that slides down to the center of the funnel-shaped bottom surface in the mixing kettle upward, and cooperates with the stirring blades to mix the materials more evenly.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
