Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary equipment for plant protection machines, in particular to a circulating medicine mixing device for plant protection machines. Background Technique

[0002] Plant protection machinery refers to machinery for rural plant protection. Since some plant protection machinery sprays liquid medicine on plants over a large area during use, the plant protection machinery needs to continuously prepare liquid medicine, so a circulating medicine mixing device for plant protection machines is required.

[0003] According to the description in the circulating medicine mixing device for plant protection machines (authorization announcement number: CN 211462771U) disclosed on the patent network, "The utility model relates to the technical field of plant protection machines, especially a circulating medicine mixing device for plant protection machines, including a mixing tank. An electric motor is fixedly installed above the interior of the mixing tank. The lower end of the control output of the electric motor is fixedly installed with a rotating shaft. A mixing spiral is welded on the outer side of the rotating shaft. A medicine storage box is fixedly installed on one side of the mixing tank. A medicine adding hopper is welded and communicated with the upper end of the medicine storage box. A medicine inlet pipe is communicated with the bottom of the medicine storage box. The lower end of the medicine inlet pipe is fixedly connected with a diaphragm pump. The diaphragm pump is fixedly installed outside the mixing tank. The output end of the diaphragm pump is fixedly installed with a connecting pipe. The end of the connecting pipe is communicated with the mixing tank. A water inlet pipe is fixedly installed above the other side of the mixing tank. A water outlet pipe is fixedly installed below the other side of the mixing tank. This medicine mixing device has a good mixing effect and is worthy of promotion."

[0004] Regarding the above description content, the applicant believes that the following problems exist:

[0005] During the use of this utility model, the liquid medicine sucked is sent into the mixing tank through the diaphragm pump. Since there is a certain pressure when the diaphragm pump adds the liquid medicine into the mixing tank, the liquid medicine is sprayed into the mixing tank, causing the liquid medicine to mix with the water inside the mixing tank and also having a mixing effect. Then, it is mixed by the mixing spiral. However, in actual use, the bottom of the inner wall of the mixing tank is higher than the water outlet pipe, which will cause the liquid medicine in the mixing tank to not be completely discharged during liquid discharge and will remain. When different liquid medicines are mixed, the liquid medicines will repel each other, causing the liquid medicine to fail or even produce toxicity, which is harmful to plants. Therefore, it is necessary to improve a circulating medicine mixing device for plant protection machines to solve the above problems. Content of the Utility Model

[0035] Embodiment 2:

[0036] Please refer to Figure 6 , and in combination with Embodiment 1, it is further obtained that the medicine adding mechanism 7 includes a mounting frame 71. The mounting frame 71 is fixedly installed on the right side of the medicine mixing tank 1. The top of the mounting frame 71 is fixedly installed with a medicine storage tank 72. The top of the medicine storage tank 72 is fixedly installed with a medicine inlet hopper 73. Two mounting plates 74 are fixedly installed on the left side of the medicine storage tank 72. The bottom of the medicine storage tank 72 is fixedly installed with a medicine inlet pipe A 75. The bottom of the mounting frame 71 is fixedly installed with a water pump 76. The bottom of the water pump 76 is fixedly installed with a medicine inlet pipe B 77. A check valve 78 is arranged outside the medicine inlet pipe B 77, so that the flow direction of the liquid medicine inside the medicine storage tank 72 is one-way and reverse flow into the medicine storage tank 72 will not occur.

[0037] Furthermore, one end of the medicine inlet pipe B 77 away from the water pump 76 is fixedly installed with the medicine mixing tank 1, one end of the medicine inlet pipe A 75 away from the medicine storage tank 72 is fixedly installed with the water pump 76. The medicine inlet pipe A 75 is arranged inside the mounting frame 71. One side of the mounting plate 74 away from the medicine storage tank 72 is fixedly installed with the medicine mixing tank 1, making the installation of the medicine storage tank 72 more stable.

[0038] During the actual operation process, when this device is in use, the L-shaped mounting plate 3 is attached to the plant protection machine, and the bolt A4 is turned to install the L-shaped mounting plate 3 on the plant protection machine, so that this device can be installed on the plant protection machine for use. When not in use, it can be disassembled to reduce the weight of the plant protection machine and facilitate transportation. The liquid medicine is added into the medicine storage tank 72 through the medicine inlet hopper 73. The medicine storage tank 72 is used to provide the liquid medicine. The water pump 76 is started to drive the liquid medicine in the medicine storage tank 72 to enter the inside of the medicine mixing tank 1 through the medicine inlet pipe A75 and the medicine inlet pipe B77. When the liquid medicine enters the inside of the medicine mixing tank 1, the water for dilution is simultaneously injected into the medicine mixing tank 1 through the water inlet pipe 2. The motor A613 is started to drive the bevel gear A614 to rotate, so that the bevel gear B615 and the bevel gear C617 rotate synchronously, driving the stirring roller A616 and the stirring roller B618 to rotate in reverse synchronously, so that the water and the liquid medicine are fully mixed in the medicine mixing tank 1. After the mixing is completed, the motor B625 is started to drive the gear 626 to rotate. The annular rack 623 meshes with the gear 626, driving the turntable 622 to rotate outside the rotating shaft 621, so that the material discharge hole coincides with the discharge pipe 5. The stirring roller A616 rotates to drive the rotating rod 619 to rotate, so that the rotating rod 619 and the scraper 6112 scrape the liquid medicine adhering to the inner wall of the medicine mixing tank 1. When the scraper 6112 is worn out after being used for a long time, the spring 6110 drives the slider 6111 to move, so that the scraper 6112 always fits the inner wall of the medicine mixing tank 1, so that the uniformly stirred diluted liquid medicine in the medicine mixing tank 1 can all be discharged into the medicine storage tank of the plant protection machine through the discharge pipe 5 for use, avoiding residue. When the discharging in the medicine mixing tank 1 is completed, the motor B625 is started so that the material discharge hole no longer coincides with the discharge pipe 5, and the above operations can be repeated to perform the next stirring and dilution of the liquid medicine, so that the diluted liquid medicine in the medicine storage tank of the plant protection machine can be immediately injected with the newly diluted liquid medicine after being used up, ensuring continuous use. When changing the liquid medicine, clean water can be injected through the water inlet pipe 2 to clean the inside of the medicine mixing tank 1, which is convenient for the stirring of another liquid medicine.

[0039] It should be noted that in this article, relative terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or elements inherent to such process, method, article or device.
