Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery, in particular to a seed coating and drying integrated machine. Background Art

[0002] Seed coating refers to coating the surface of seeds with a liquid made of fungicides, pesticides, micro-fertilizers, colorants or fillers to improve the disease resistance and stress resistance of seeds, accelerate seed germination and increase yield. After coating, seeds need to be dried.

[0003] The current seed coating machine adds a corresponding amount of liquid medicine to the seeds, and then stirs them to coat the surface of the seeds. Since the liquid medicine is added unevenly, it is easy for the seeds to stick together and form clumps due to excessive local liquid medicine, which affects the coating effect. Some coating machines have a drying function. After the seeds are coated, hot air is blown into the stirred seeds to dry the coated seeds. However, the hot air can only dry the seeds on the surface, so the drying effect is poor and the drying efficiency is low. Utility Model Content

A driving motor 13 for driving the rotating wheel 12 to rotate is fixedly arranged at the bottom of the box body 2, a liquid outlet 23 is arranged on the side wall of the liquid adding box 7, a closed heating chamber 8 is provided between the box body 2 and the inner liner 3, an electric heater 21 is arranged in the heating chamber 8, and return air holes 6 are evenly distributed along the circumferential direction on the top of the inner liner 3 to connect the heating chamber 8 with the inner part of the inner liner 3, and a fan 11 is arranged at the bottom of the box body 2 to connect the heating chamber 8 with the inner part of the inner liner 3.

[0024] The liquid adding box 7 comprises a circular closed box body 18 and a liquid injection hole 17 arranged at the top of the box body 18. The inside of the box body 18 is a liquid storage cavity 16, and the liquid outlet holes 23 are evenly distributed on the side wall of the box body 18. The bottom of the box body 18 is a cone with a large mouth facing upward. A connecting column 20 is fixedly arranged on the top surface of the rotating wheel 12, and a supporting column 19 is fixedly arranged under the box body 18. The connecting column 20 is plugged with the supporting column 19. The upper part of the connecting column 20 is a quadrangular prism, so that the supporting column 19 can be driven to rotate.

[0025] The bottom of the inner liner 3 is fixedly connected to the housing 2, the runner 12 is a disc-shaped wheel with a high center and a low edge, the runner 12 is rotatably connected to the bottom of the housing 2, the edge of the runner 12 is in clearance with the inner liner 3, the clearance is smaller than the size of the seeds, the lower part of the runner 12 and the housing 2 are provided with an intermediate cavity 15, the runner 12 is provided with air holes 14 that connect the intermediate cavity 15 and the upper part of the runner 12, the air holes 14 are evenly distributed on the runner 12, and the diameter of the air holes 14 is smaller than the size of the seeds. A radial material stripping plate 22 is fixedly provided on the upper part of the runner 12, the bottom of the housing 2 is provided with an air inlet 9, the bottom surface of the housing 2 is provided with an air suction hole 10 at the location of the heating cavity 8, and the air inlet and air outlet of the fan 11 are connected to the air suction hole 10 and the air inlet 9 respectively.

[0026] The working process of the utility model is:

[0027] First, the seeds are introduced into the inner liner 3, and the seeds fall on the wheel 12 at the bottom of the inner liner 3. The liquid medicine is injected into the liquid storage chamber 16 through the injection hole 17, and the liquid medicine accumulates at the bottom of the liquid storage chamber 16. Then the driving motor 13 drives the wheel 12 to rotate, and the wheel 12 drives the seeds to rotate through the material stripping plate 22. Under the action of centrifugal force, the part of the seed close to the inner liner 3 rises along the inner wall of the inner liner 3, and then falls under the action of gravity, so that it turns inside the inner liner 3. At the same time, under the action of centrifugal force, the liquid medicine in the liquid storage chamber 16 is thrown toward the inner wall of the box body 18 under the action of centrifugal force, and then evenly sprayed toward the turning seeds through the liquid outlet 23.

[0028] After the liquid medicine is filled, the seeds and the liquid medicine are evenly mixed, the electric heater 21 is started, and the fan 11 is started. Under the action of the fan 11, hot air is blown from the hot air chamber 8 through the fan 11, the middle chamber 15 and the air holes 14 to the seeds being turned over, and the seeds are dried. Part of the hot and humid air is discharged from the top of the inner tank 3. In addition, when the hot air is blown upward through the air holes 14, it will pass through the gaps between the seeds and exert an upward force on the seeds, which is more conducive to the turning of the seeds.

[0029] The liquid adding box 7 is detachable, and the amount of liquid medicine added to the liquid adding box 7 can be accurately matched according to the amount of the corresponding seeds, which can prevent excessive liquid medicine and insufficient liquid medicine. The liquid medicine is uniformly sprayed through the liquid outlet 23 by centrifugal force, and then uniformly mixed in the seeds being turned over, which can prevent the seeds from sticking together due to excessive local liquid medicine. The liquid adding box 7 has a simpler structure and is more convenient to clean. It does not need to be equipped with a liquid adding pump and corresponding pipelines, and it is more reliable when working.

[0030] Example 2

[0031] The difference between this embodiment and embodiment 1 is that:

[0032] A U-shaped frame 1 is disposed outside the box body 2, the box body 2 is located inside the frame 1, and both sides of the middle of the box body 2 are rotatably connected to the frame 1 respectively. A reduction motor 4 for driving the box body 2 to rotate is disposed on the frame 1.

[0033] When the coated seeds are dried, the reduction motor 4 drives the box 2 to rotate and pour out the dried seeds.

[0034] Example 3

[0035] The difference between this embodiment and embodiment 2 is that:

[0036] The inner wall of the inner container 3 is fixedly provided with a strip-shaped baffle 5 , the baffle 5 is inclined, and the baffle 5 is four strips evenly distributed around the axis of the inner container 3 .

[0037] The four ribs rise in a spiral shape, which can make the seeds in the inner container 3 rise higher, so that the surface area of ​​the seeds is larger when they are turned over, which is conducive to full contact with the liquid medicine and is more conducive to improving the drying effect.
