Coating device for breeding of peanut seeds

Abstract

This utility model discloses a coating device for peanut seed breeding, including a cylinder. A motor is connected to a flange at one end of the cylinder, and a spiral blade is fixedly connected to the output shaft of the motor. A feed hopper is fixedly connected to the surface of the cylinder, and the interior of the feed hopper is connected to the interior of the cylinder. A fixing frame is fixedly connected to the surface of the cylinder. Through the setting of protrusions and stirring rods, when the spiral blades rotate, they drive the seeds to make spiral motion along the axis of the stirring rod, realizing preliminary conveying and dispersion. The protrusions on the stirring rod and spiral blades will break the regularity of seed movement. Under the obstruction and pushing of the protrusions and stirring rods, the seeds constantly change their direction of movement, and frequently collide and rub against each other, greatly increasing the probability of contact with the coating liquid. This allows the coating liquid to coat the seed surface more evenly, effectively avoiding the problem of uneven coating thickness caused by insufficient stirring.

Description

Technical Field

[0001] This utility model belongs to the field of peanut seed breeding technology, and in particular relates to a coating device for peanut seed breeding. Background Technology

[0002] Peanuts are annual herbaceous plants belonging to the legume family and the genus Arachis. Peanuts require seed coating during breeding. Seed coating technology can increase seed survival rate, improve sowing efficiency, and protect seeds from diseases. Seed coating involves using a liquid adhesive to form an adhesive film on the seed surface, then coating the seed with fungicides, insecticides, micronutrients, and plant growth regulators. Existing patent number 202221768371.0, entitled "A Seed Coating Device for High-Yield Breeding," includes a conveying pipe, an auger installed in the conveying pipe for conveying materials, and a drying chamber installed at the end of the conveying pipe. The conveying pipe is inserted into the drying chamber; a spray device is installed in the middle of the conveying pipe; a discharge port and a hot air fan are installed at the bottom of the drying chamber; a hot air pipe is fixed to the top of the drying chamber, with the end of the hot air pipe furthest from the drying chamber inserted into the conveying pipe.

[0003] However, in the above-mentioned scheme, the seeds are transported and the coating solution is mixed solely by the auger. The movement trajectory of the seeds within the auger's transport channel is relatively simple, which may lead to uneven seed coating thickness due to insufficient mixing. Utility Model Content

[0004] To address the problems existing in the prior art, this utility model provides a coating device for peanut seed breeding. Under the obstruction and pushing of the protrusions and stirring rod, the seeds continuously change their direction of movement, frequently colliding and rubbing against each other, which greatly increases the probability of contact with the coating liquid. This allows the coating liquid to coat the seed surface more evenly, effectively avoiding the problem of uneven coating thickness caused by insufficient stirring.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a coating device for peanut seed breeding, comprising a cylinder, a motor connected to a flange at one end of the cylinder, a spiral blade fixedly connected to the output shaft of the motor, a feed hopper fixedly connected to the surface of the cylinder, the interior of the feed hopper communicating with the interior of the cylinder, a fixing frame fixedly connected to the surface of the cylinder, a material box movably connected to the interior of the fixing frame, a material pipe fixedly connected to the bottom end of the material box, a material pump installed on the material pipe, a diversion box fixedly connected to the end of the material pipe away from the material box, multiple spray pipes fixedly connected to the bottom end of the diversion box, the interior of the spray pipe communicating with the interior of the diversion box, and the spray pipes movably penetrating and extending into the interior of the cylinder, an installation groove opened on the surface of the cylinder, a receiving box movably connected to the interior of the installation groove, an arc-shaped filter screen installed at the top of the receiving box, multiple protrusions installed on the surface of the spiral blades, and a stirring rod fixedly connected to the output shaft of the motor.

[0006] Furthermore, multiple fixing rods are fixedly connected to the opposite surfaces of the material bin and the diversion box.

[0007] Furthermore, the contents of the hopper and the distribution box are connected by a material pipe.

[0008] Compared with the prior art, the beneficial effects of this utility model are:

[0009] By incorporating protrusions and a stirring rod, the rotating blades cause the seeds to spiral along the axis of the stirring rod, achieving initial transport and dispersion. The protrusions on the stirring rod and spiral blades disrupt the regularity of the seed movement. Under the obstruction and pushing of the protrusions and the stirring rod, the seeds constantly change their direction of movement, frequently colliding and rubbing against each other, greatly increasing the probability of contact with the coating liquid. This allows the coating liquid to more evenly coat the seed surface, effectively avoiding uneven coating thickness caused by insufficient stirring. Attached Figure Description

[0015] See appendix Figure 1-2 As shown, a coating device for peanut seed breeding includes a cylinder 1. A motor 2 is connected to a flange at one end of the cylinder 1. A spiral blade 3 is fixedly connected to the output shaft of the motor 2. A feed hopper is fixedly connected to the surface of the cylinder 1, and the interior of the feed hopper is connected to the interior of the cylinder 1. A fixing frame 6 is fixedly connected to the surface of the cylinder 1. A material box 7 is movably connected to the interior of the fixing frame 6. A material pipe 8 is fixedly connected to the bottom of the material box 7. A material pump 11 is installed on the material pipe 8. A diversion box 9 is fixedly connected to the end of the material pipe 8 away from the material box 7. Multiple spray pipes 10 are fixedly connected to the bottom of the diversion box 9. The interior of the spray pipes 10 is connected to the interior of the diversion box 9, and the spray pipes 10 movably penetrate and extend into the interior of the cylinder. An installation groove is opened on the surface of the cylinder 1. A receiving box is movably connected to the interior of the installation groove. An arc-shaped filter screen is installed at the top of the receiving box. Multiple protrusions 4 are provided on the surface of the spiral blade 3. A stirring rod 5 is fixedly connected to the output shaft of the motor 2.

[0016] Multiple fixing rods are fixedly connected to the opposite surfaces of the material bin 7 and the diversion box 9.

[0017] The contents of the material bin 7 and the diversion box 9 are connected by the material pipe 8.

[0018] Working principle: During use, peanut seeds enter the cylinder 1 through the feed hopper. The motor 2 drives the spiral blades 3 and the stirring rod 5 to rotate, conveying the peanut seeds inside the cylinder 1. The coating liquid is added through the feed hopper 7 and pumped by the feed pump 11 and feed pipe 8 to the distribution box 9. From there, it is distributed to the spray pipe 10 and finally sprayed into the cylinder 1. The protrusion 4 and the stirring rod 5, when the spiral blades rotate, cause the seeds to move axially along the stirring rod 5. The spiral motion achieves initial conveying and dispersion, while the protrusions 4 on the stirring rod 5 and the spiral blades 3 disrupt the regularity of seed movement. Under the obstruction and pushing of the protrusions 4 and the stirring rod 5, the seeds constantly change their direction of movement, frequently colliding and rubbing against each other, greatly increasing the probability of contact with the coating liquid. This allows the coating liquid to coat the seed surface more evenly, effectively avoiding the problem of uneven coating thickness caused by insufficient stirring. The motor 2 and the cylinder 1 are connected by a flange, which facilitates disassembly for cleaning the spiral blades 3. The receiving box can be disassembled for cleaning the arc-shaped filter screen.
