DETAILED DESCRIPTION

[0024] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] A kind of medicine mixing equipment for seed processing is a seed mixer or a seed medicine mixing machine. The seed medicine mixing machine puts raw materials such as seeds and medicines into a hopper, mixes them fully through the action of a mixing device, and finally discharges the evenly mixed seeds and medicines from the discharge port.

[0026] The vibration force generated by the vibration motor in the existing equipment can vibrate the screening plate to screen the seeds and intercept the straw and debris. However, the long-term vibration of the vibration motor will cause wear and damage to the equipment itself. The main reason is that the vibration will cause the internal parts of the equipment to rub against each other, and the friction will generate heat, which will cause the parts to wear. Long-term friction and wear will lead to the performance of the equipment being reduced, or even failure. Figure 1-Figure 4 , provides a seed processing medicine mixing equipment, including a screening tank 1 and a feed pipe 11, a discharge pipe 12, and a liquid inlet pipe 13 fixedly connected to the screening tank 1, a screening plate 2 is arranged inside the screening tank 1, the inside of the screening plate 2 is concave, a plurality of sieve holes are opened at the bottom of the screening plate 2, and a circular hole is opened at the center of the screening plate 2, and the range of the circular hole will not touch the rotating shaft 31 and interfere with its operation when the screening plate 2 moves back and forth horizontally.

[0027] refer to Figure 1-Figure 4As shown, the vibration force generated by the vibration motor in the existing equipment can vibrate the screening plate to screen the seeds and intercept straw debris. However, the long-term vibration of the vibration motor will cause wear and damage to the equipment itself. The main reason is that the vibration will cause mutual friction between the internal parts of the equipment, and the friction will generate heat, which will cause wear of the parts. Long-term friction and wear will lead to performance degradation of the equipment and even failure problems. In order to intercept the straw debris without damaging the screening tank 1, the following settings are made. The bottom end of the screening tank 1 is provided with a screening mechanism 4 for driving the screening plate 2 to vibrate horizontally and reciprocatingly to intercept the straw debris in the seeds. The screening mechanism 4 includes a motor 41 fixed to the bottom of the screening tank 1 and a power rod 45 slidably sleeved inside the screening tank 1. The outer wall of the output end of the motor 41 is provided with a power component for driving the power rod 45 to move reciprocatingly and horizontally. The power component includes a rotating A belt 49 is provided on the outer wall of the output end of the motor 41 and the rotating rod 42 on the inner wall of the sub-screening tank 1, and two pulleys are provided inside the belt 49. The two pulleys are respectively fixed on the output end of the motor 41 and the outer wall of the rotating rod 42. A pull plate 43 is fixedly connected to the circumferential surface of the top end of the rotating rod 42. An end of the pull plate 43 away from the rotating rod 42 is movably connected to a connecting plate 44. An end of the connecting plate 44 away from the pull plate 43 is movably connected to an end of a power rod 45 away from the sub-screening plate 2. An end face of the power rod 45 is fixedly connected to the circumferential surface of one side of the sub-screening plate 2. Starting the motor 41 drives one of the pulleys to rotate at the output end, and one of the pulleys drives the other pulley to rotate through the belt 49. The rotation of the other pulley drives the rotating rod 42 to rotate. The rotation of the rotating rod 42 drives the pull plate 43 to rotate, and then the connecting plate 44 reciprocates to pull the power rod 45 to move back and forth laterally. The power rod 45 moves back and forth laterally to drive the sub-screening plate 2 to move synchronously. The circumferential surface of the other side of the sub-screening plate 2 is provided with a vibration driving assembly for cooperating with the power assembly to make the sub-screening plate 2 vibrate. The vibration driving assembly includes a retractable cylinder 46 fixed on the circumferential surface of the sub-screening plate 2. The internal sliding sleeve of the retractable cylinder 46 is provided with an insertion rod 47 fixedly connected to the inner wall of the sub-screening tank 1. The outer wall of the insertion rod 47 is fixedly connected with a slider. The inner wall of the retractable cylinder 46 is provided with a slide rail. The slider slides in the slide rail to limit the insertion rod 47. The outer wall of the insertion rod 47 is sleeved with a vibration spring 48 fixedly connected to the storage tube 46 and the screening tank 1. When the screening plate 2 moves to the left, the insertion rod 47 will gradually be inserted into the storage tube 46 and compress the vibration spring 48. When the screening plate 2 moves to the right, the insertion rod 47 will gradually move out of the storage tube 46 and stretch the vibration spring 48. The above cycle can generate a periodic vibration force, thereby causing the screening plate 2 to vibrate individually. The vibration force can help the seeds jump on the screening plate 2, thereby effectively separating the straw debris. When the screening plate 2 vibrates, the straw debris will jump upward, and the seeds will be separated through the screening plate 2, thereby improving the screening effect.

[0028] refer to Figure 1As shown, piling all seeds on the top of the sieve plate 2 for screening will limit the screening capacity and reduce the screening output. Due to the large amount of accumulated seeds, the screening process may become slow, resulting in reduced screening efficiency, and the larger straw debris mixed in the seeds will occupy the sieve holes and hinder the seeds from passing through, which will lead to inaccurate screening results and fail to achieve the ideal seed separation effect. In order to obtain a better screening effect, the following settings are made: the top of the sieve plate 2 is provided with a stirring assembly 3 for evenly screening the seeds. The material distribution component 5 includes a rotating drum 52 rotating at the bottom end of the feed pipe 11, and the bottom end of the rotating drum 52 is fixedly connected to a duck tongue material transfer plate 51, and the duck tongue material transfer plate 51 is fixed to the top of the rotating shaft 31. The seeds enter from the feed pipe 11 and fall on the top of the duck tongue material transfer plate 51, and will eventually slide to the top of the sub-screen plate 2 through the slope of the duck tongue material transfer plate 51. The rotation of the rotating shaft 31 drives the duck tongue material transfer plate 51 to rotate in a circle, so that the seeds fall evenly on the top of the sub-screen plate 2, so as to ensure proper seed fluidity and achieve a more accurate and efficient screening process.

[0029] refer to Figure 1-Figure 2 As shown, the interior of the screening tank 1 is provided with a stirring component 3 for mixing seeds and medicines under the synchronous drive of the power component. The stirring component 3 includes a rotating shaft 31 fixed to the output end of the motor 41, and the outer wall of the rotating shaft 31 is fixedly connected with a stirring blade 32. The output end of the motor 41 drives the rotating shaft 31 to rotate, and then the stirring blade 32 stirs the seeds and medicines in the screening tank 1.

[0030] As shown in reference 3, when the seeds vibrate on the screening plate 2, straw impurities will be intercepted on the screening plate 2. At the same time, the friction and collision force will also cause the fine particles on the surface of the seeds or the debris between the particles to fall off and be raised, forming a certain amount of dust. In order to clean the straw impurities and dust in time, the following settings are made: the circumferential surface of the screening tank 1 is provided with an adsorption component 6 for cleaning the dust on the surface of the seeds and straw debris. The adsorption component 6 includes a circular ring tube 62 fixed on the circumferential surface of the screening tank 1, and the outer circumferential surface of the circular ring tube 62 is fixed A connecting pipe 61 is connected, and a plurality of hoses 63 are fixedly connected to the inner circumference of the annular pipe 62 at equal intervals. The ends of the plurality of hoses 63 away from the annular pipe 62 are fixedly connected to the inside of the sub-screening plate 2. After the connecting pipe 61 is connected to the exhaust end of the fan in the prior art, the fan is started, and the negative pressure generated by the fan is expanded through the annular pipe 62, so that negative pressure is generated at the plurality of hoses 63 to absorb the dust. Through the connecting pipe 61, the dust and straw impurities inside the sub-screening tank 1 can be sucked out by the fan in the prior art and discharged into the inside of the filter box in the prior art.

[0031] refer to Figure 2-Figure 3As shown, applying too much agent to the seeds will result in too long a soaking time or too high a concentration of the agent, which will damage the seeds. Applying too little agent to the seeds will result in the agent having an unclear effect and unable to achieve the expected disease prevention, growth promotion or other management effects, thereby reducing the efficiency of the agent. In order to reasonably control the amount of agent used, the following settings are made: a monitoring device 7 for indicating the liquid level of the agent added is provided inside the screening tank 1, and the monitoring device 7 includes a limiting ring 71 fixed to the inner wall of the screening tank 1, and the limiting ring 71 A high liquid level sensor 72 is fixedly installed at the bottom, and a warning light 73 electrically connected to the high liquid level sensor 72 is fixedly installed on the circumference of the screening tank 1. When the operator pours the medicine, if the medicine contacts the high liquid level sensor 72, the high liquid level sensor 72 will detect the change in liquid level and send a signal to the external controller. After receiving the signal, the external controller can execute the preset control logic to light up the control warning light 73 to remind the operator to stop pouring the medicine. In this way, the control and monitoring of the amount of medicine used can be achieved.

[0032] The above are only preferred embodiments of the present invention and are 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.
