Specific embodiments

[0020] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] As Figure 1 shown, a wheat planting medicament dressing device includes a stirring barrel 1. A discharge pipe 11 is further arranged on the outer surface of the stirring barrel 1, which can discharge the evenly stirred wheat seeds. A first stirring roller 12 is rotatably installed on the bottom surface of the inner cavity of the stirring barrel 1, so that the device can stir the medicament during use, and the surface of the wheat seeds can be evenly coated with the medicament. A spiral auger 13 is further fixed on the outer surface of the stirring barrel 1. The spiral auger 13 is a prior art and can convey the wheat seeds into the stirring barrel 1, so that the wheat seeds and the medicament are stirred and mixed. A feeding assembly 2 is further arranged at the output end of the spiral auger 13.

[0022] As Figure 2 and Figure 3 shown, the feeding assembly 2 includes a connecting pipe 21 fixedly connected to the spiral auger 13, so that the materials conveyed by the spiral auger 13 can enter the connecting pipe 21, and at the same time, the materials in the connecting pipe 21 can also enter the stirring barrel 1. An impeller 22 is rotatably installed on the inner surface of the connecting pipe 21, so that the impeller 22 can be driven to rotate when the materials are conveyed. A mounting bracket 23 is fixed on the outer surface of the connecting pipe 21, and an upper part of the outer surface of the mounting bracket 23 is fixedly provided with a mounting box 24. During use of the device, the medicament to be used is poured into the mounting box 24. A sealing plate 25 is further arranged in the inner cavity of the mounting box 24. Through grooves 26 are respectively arranged on the sealing plate 25 and the lower end of the mounting box 24, which can allow the medicament in the mounting box 24 to enter the stirring barrel 1. An adjustment assembly 3 is further arranged on the bottom surface of the inner cavity of the mounting box 24.

[0023] As Figure 3 and Figure 4As shown, the adjusting assembly 3 includes a friction wheel 31 rotatably mounted on the bottom surface of the inner cavity of the installation box body 24, and the friction wheel 31 is fixedly connected to the impeller 22, so that when the impeller 22 rotates, it can drive the friction wheel 31 to rotate. At the same time, due to the design of the impeller 22, the rotational speed inside the friction wheel 31 can be adapted to the conveying speed of wheat seeds (that is, when the wheat seeds are conveyed quickly, the friction wheel 31 can rotate quickly; when the wheat seeds are conveyed slowly, the friction wheel 31 can rotate slowly). A second stirring roller 32 fixedly connected to the friction wheel 31 is also rotatably mounted at the upper end of the sealing plate 25, so that when the second stirring roller 32 rotates, it can stir the medicament in the installation box body 24, facilitating the mixing of the medicament and wheat seeds. An arc-shaped friction strip 34 adapted to the through groove 26 is also slidably mounted on the bottom surface of the inner cavity of the installation box body 24. The arc-shaped friction strip 34 is used to seal the installation box body 24, and at the same time, the sealing degree of the arc-shaped friction strip 34 to the through groove 26 is adjusted according to the sliding angle of the arc-shaped friction strip 34, so as to control the amount of the medicament entering the stirring barrel 1. An arc-shaped spring 35 is fixed to the counterclockwise side surface of the arc-shaped friction strip 34.

[0024] In addition, when the arc-shaped spring 35 is in a natural state, the arc-shaped friction strip 34 seals the through groove 26, so that when the spiral auger 13 does not convey wheat seeds (that is, when the impeller 22 does not rotate), the medicament in the installation box body 24 cannot enter the stirring barrel 1. One end of the arc-shaped spring 35 far from the arc-shaped friction strip 34 is also fixed with an arc-shaped rack 36 slidably connected to the installation box body 24. The arc-shaped rack 36 can slide clockwise or counterclockwise on the bottom surface of the inner cavity of the installation box body 24. A limiting block 37 for limiting the arc-shaped friction strip 34 is fixed to the bottom surface of the inner cavity of the installation box body 24, so that when the arc-shaped rack 36 slides toward the side close to the arc-shaped friction strip 34, it can compress the arc-shaped spring 35. Due to the design of the meshing of the friction wheel 31 and the arc-shaped friction strip 34, the arc-shaped spring 35 can move different distances according to the rotational speed of the friction wheel 31 itself.

[0025] Specifically, when the rotation speed of the friction wheel 31 is relatively slow, due to the mutual friction between the friction wheel 31 and the arc-shaped spring 35, the arc-shaped friction strip 34 rotates counterclockwise, enabling the medicament in the installation box body 24 to enter the stirring barrel 1 through the through groove 26. At the same time, due to the design of the arc-shaped spring 35, the arc-shaped friction strip 34 can move an appropriate distance according to the rotation speed of the friction wheel 31, further enabling the device to automatically control the feeding amount of the medicament according to the feeding amount of wheat seeds, which facilitates the operation of the device. A gear 38 meshing with the arc-shaped rack 36 is also rotatably installed on the bottom surface of the inner cavity of the installation box body 24, so that when the gear 38 rotates, it drives the arc-shaped rack 36 to rotate, thereby compressing the arc-shaped spring 35. When designing the gear 38, it is necessary to consider fixing it to prevent the elastic force of the arc-shaped spring 35 from causing the arc-shaped rack to move away from the arc-shaped spring, thus affecting the normal operation of the device. Therefore, the adjusting rod for adjusting the gear 38 needs to be fixed during design to make the device more stable during use.

[0026] At the same time, through the design of the mutual friction between the friction wheel 31 and the arc-shaped friction strip 34, when the friction wheel 31 rotates, the moving distance of the arc-shaped friction strip 34 can be adjusted according to its own rotation speed and the elasticity of the arc-shaped spring 35 (for example: when the rotation speed of the friction wheel 31 is 20 rpm, the arc-shaped friction strip 34 can only be opened by 10%, and when the rotation speed of the friction wheel 31 is 40 rpm, the arc-shaped friction strip 34 can only be opened by 20%). Further, the amount of the medicament entering the stirring barrel 1 can be adjusted according to the amount of wheat entering the stirring barrel 1, without the need for operators to adjust, which facilitates the operation of the device and also increases the applicability of the device during use.

[0027] The specific implementation manner of this embodiment is as follows: When the device is in use, the medicament to be used is added into the installation box body 24, and then the spiral auger 13 is controlled to transport wheat seeds into the stirring barrel 1. The spiral auger 13 transports the wheat seeds, and at the same time, when the wheat seeds are transported, they can push the impeller 22 to rotate. When the impeller 22 rotates, it drives the friction wheel 31 and the second stirring roller 32 to rotate. When the second stirring roller 32 rotates, it can stir the medicament in the installation box body 24 to prevent the powdery medicament in the installation box body 24 from caking, making the device more stable during use;

[0028] When the friction wheel 31 is in use, due to the mutual friction with the arc-shaped friction strip 34, the arc-shaped friction strip 34 rotates counterclockwise, further enabling the arc-shaped friction strip 34 not to seal the through groove 26. At the same time, due to the design of the arc-shaped spring 35, the arc-shaped friction strip 34 can move an appropriate distance according to the rotation speed of the friction wheel 31, further enabling the device to automatically control the feeding amount of the medicament according to the feeding amount of wheat seeds, which facilitates the operation of the device;

[0029] Due to the design of the arc-shaped rack 36 and the gear 38, the device can adjust the softness and hardness of the arc-shaped spring 35 during use, and further adjust the moving distance of the arc-shaped friction strip 34 of the friction wheel 31 at the same speed, so that the device can be applicable to different medicaments during use, increasing the applicability of the device during use.

[0030] It should be noted that the specific installation methods, circuit connection methods, and control methods of the first stirring roller 12, the spiral auger 13, the impeller 22, etc. in the present utility model are all conventional designs, and the present utility model will not be elaborated in detail.

Those skilled in the art should understand that the present utility model is not limited by the above embodiments.
