Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and more specifically, to a seed coating machine with high coating efficiency. Background Technology

[0002] A seed coating machine is a machine that coats selected seeds with a coating agent, granulating them. There are rotary drum type, floating type, and combined type. It consists of a coating tank, dispensing, metering, spraying, air supply, power, and transmission devices. The seeds and coating agent repeatedly rub and compress against each other inside the coating tank, forming a coating layer of a certain strength on the seed surface. Coated seeds are uniform in size and shape, which is beneficial for mechanical sowing, improving sowing accuracy, and reducing seed consumption and thinning workload.

[0003] An existing patent describes a small seed coating device (patent authorization number CN210016889U). A triangular fixing frame is vertically positioned above a base, and two stirring tanks are fixed on the triangular fixing frame. A motor is located at the center of the base, and the motor's output end is connected to a drive shaft. Two stirrers are mounted on the drive shaft and are located inside the stirring tanks. The upper end of the drive shaft is fitted with a bearing located at the center of the upper end of the triangular fixing frame. The device features a simple structure, low manufacturing cost, easy and convenient maintenance, labor saving, and high work efficiency. It is widely applicable to the coating of seeds from various crops such as corn, soybeans, wheat, and peanuts.

[0004] However, in patent authorization number CN210016889U, when the seed coating agent baffle is opened, the seed coating agent flows into the mixing tank under the action of gravity. Under the continuous stirring of the first and second stirrers, the seed coating agent will be fully mixed with the seeds. Since the coating agent and seeds are mixed by a single stirring method, the seed has poor fluidity inside the mixing tank. The seeds at the bottom of the mixing tank that cannot be stirred have poor binding effect with the coating agent, so the stirring time needs to be extended, which will cause serious seed wear and affect its survival rate. Therefore, we propose a seed coating machine with high coating efficiency to solve the above problems. Utility Model Content

[0011] A support is provided on the outside of the mixing tank. A through hole is provided at the top of the support.

[0019] 3. Beneficial Effects

[0020] Compared with existing technologies, the advantages of this utility model are:

[0021] (1) In this scheme, by turning on the vibration motor, the elastic force of the spring is used to make the guide column slide up and down through the guide hole opened at the bracket under the influence of vibration, thereby causing the protrusion to drive the mixing tank to vibrate up and down. At the same time, by turning on the drive motor, the spiral blades are rotated inside the cylinder through the drive shaft, so that the seeds at the bottom of the mixing tank enter the inner side of the cylinder through the bottom notch, then are lifted up, and finally discharged through the top notch. This can effectively accelerate the fluidity of the seeds, thereby improving the efficiency of seed coating.

[0022] (2) In this scheme, the coating agent is added to the inside of the measuring cup and the amount is accurately measured. Then, the stop valve is opened and the coating agent is added to the mixing tank through the feeding pipe to ensure the accurate amount of coating agent, thereby ensuring the coating effect of the seeds.

[0023] (3) In this solution, the equipment is shut down in time by using a timer to set the duration of the seed coating process, thus avoiding damage caused by prolonged friction between seeds. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0031] Example:

[0032] Please see Figure 1-4 A seed coating machine with high coating efficiency includes a mixing tank 1, a discharge pipe 2 connected to the bottom of the mixing tank 1, and a gate valve 3 installed at the discharge pipe 2. A cylinder 4 is fixedly connected to the inner side of the mixing tank 1. Notches 5 are symmetrically opened at the top and bottom of the side wall of the cylinder 4. A drive shaft 6 is rotatably connected to the inner side of the cylinder 4. Spiral blades 7 are welded to the outer wall of the drive shaft 6.

[0033] A carrier plate 8 is fixedly connected to the top of the mixing tank 1, and a drive motor 9 with a power output end connected to the transmission shaft 6 is installed on the upper surface of the carrier plate 8.

[0034] A support 12 is provided on the outside of the mixing tank 1. A through hole 13 is provided at the top of the support 12. A guide hole 14 is provided on the side wall of the support 12 and is connected to the through hole 13. A protrusion 10 extending to the inside of the through hole 13 is welded to the outer wall of the mixing tank 1. A guide post 11 that is slidably connected to the guide hole 14 is welded to the side wall of the protrusion 10. A spring 15 is installed below the protrusion 10.

[0035] A vibration motor 16 is installed on one side of the drive motor 9;

[0036] It should be noted that when using this high-efficiency seed coating machine, firstly, an appropriate amount of seeds to be coated is poured into the mixing tank 1. Then, the coating machine is added to the mixing tank 1, and the vibration motor 16 is turned on. Under the influence of vibration, the elastic force of the spring 15 causes the guide column 11 to slide up and down through the guide hole 14 opened at the bracket 12, thereby causing the protrusion 10 to drive the mixing tank 1 to vibrate up and down. At the same time, by turning on the drive motor 9, the spiral blade 7 is rotated inside the cylinder 4 through the drive shaft 6. This allows the seeds at the bottom of the mixing tank 1 to enter the inside of the cylinder 4 through the bottom notch 5, then be lifted upwards, and finally discharged through the top notch 5. This effectively accelerates the fluidity of the seeds, thereby improving the seed coating efficiency. After the coating work is completed, the gate valve 3 is opened, and the power output end of the drive motor 9 is reversed by the control device, thereby discharging the seeds.

[0037] like Figure 1 As shown, the top of the side wall of the mixing tank 1 is connected to a feeding pipe 17 with an L-shaped structure, and the top of the feeding pipe 17 is connected to a measuring cup 18, and a shut-off valve is installed at the bottom of the measuring cup 18.

[0038] It should be noted that by adding the coating agent to the inside of the measuring cup 18 and accurately measuring the amount, and then opening the shut-off valve to add the coating agent to the mixing tank 1 through the feeding pipe 17, the accurate amount of coating agent is ensured, thereby ensuring the coating effect of the seeds.

[0039] like Figure 3As shown, the drive shaft 6 passes through the top of the cylinder 4, and a bearing is installed at the part where the cylinder 4 and the drive shaft 6 are combined. The power output end of the drive motor 9 passes through the carrier plate 8, and the power output end of the drive motor 9 is connected to the top of the drive shaft 6 through a coupling.

[0040] It should be noted that this reduces the friction between the drive shaft 6 and the cylinder 4, ensures the rotational accuracy of the drive shaft 6, and enables the power transmitted by the drive motor 9 to be normally transmitted to the drive shaft 6.

[0041] like Figure 3 As shown, the outer diameter of the spiral blade 7 is matched with the inner diameter of the cylinder 4;

[0042] It should be noted that this allows the seeds that have entered the inner side of cylinder 4 to be smoothly lifted upwards.

[0043] like Figure 1 As shown, one end of the spring 15 is connected to the bottom wall of the through hole 13, and the other end of the spring 15 is connected to the lower surface of the protrusion 10.

[0044] It should be noted that the elastic force of the spring 15 is used to make the mixing tank 1 vibrate up and down, which is beneficial to the coating of seeds.

[0045] like Figure 1 As shown, a timer 19 is installed on the side of the drive motor 9 away from the vibration motor 16;

[0046] It should be noted that by using timer 19 to set the duration of the seed coating process, damage caused by prolonged friction between seeds can be avoided.

[0047] In use: First, pour an appropriate amount of seeds to be coated into the mixing tank 1. Then, add the coating machine into the mixing tank 1 and turn on the vibration motor 16. Under the influence of vibration, the elastic force of the spring 15 causes the guide column 11 to slide up and down through the guide hole 14 opened at the bracket 12, thereby causing the protrusion 10 to drive the mixing tank 1 to vibrate up and down. At the same time, by turning on the drive motor 9, the spiral blade 7 rotates inside the cylinder 4 through the drive shaft 6, so that the seeds at the bottom of the mixing tank 1 enter the inside of the cylinder 4 through the bottom notch 5, are then lifted upwards, and finally discharged through the top notch 5. This can effectively accelerate the fluidity of the seeds, thereby improving the efficiency of seed coating. After the coating work is completed, by opening the gate valve 3, the power output end of the drive motor 9 is reversed by the control device, thereby discharging the seeds.

[0048] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
