[0002] When planting vegetables, fruits and melons in plastic greenhouses, a problem is often encountered, that is, applying medicine to the stems to increase the thickness of the stems of the fruit bunches and prevent the stems from breaking, thereby ensuring the harvest. Most of the existing medicine applying devices are provided with a brush or sponge at one end of the medicine storage bottle, and the other end is connected with a bottle cap by a threaded or plug-in method. The bottle cap can be opened to add medicine or change medicine to the medicine storage bottle, and the stems are applied with the medicine storage bottle. The medicine liquid in the medicine storage bottle is applied to the stems by a brush or sponge. However, the bottle cap is connected by a threaded or plug-in method. When opening the bottle cap, both hands are required to cooperate in the operation, which is inefficient. Moreover, the bottle cap will be attached with medicine liquid. When opening, if the attached medicine liquid is not cleaned, the attached medicine liquid will drip on the fruits and vegetables or on the staff. If the plug-in method is used for connection, the medicine storage bottle is easy to shake during the removal process, causing the residual medicine liquid in the bottle to swing out, and the medicine liquid on the bottle cap will splash into the external environment and on the operator, which is easy to cause environmental pollution and affect the health and safety of personnel.

DETAILED DESCRIPTION

[0024] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0025] like Figure 1-Figure 2 As shown, a device for applying liquid medicine to crop stems, includes a medicine storage bottle 1 and a bottle cap 2, wherein the medicine storage bottle 1 is connected to a brush head 4 through a medicine guiding tube 3, and the medicine liquid flows through the medicine guiding tube 3 to impregnate the brush head 4, and an air valve 5 is provided on the medicine guiding tube 3; it also includes a shell 6 and a control component 7, and the control component 7 is used to control the opening and closing of the bottle cap 2, and the control component 7 includes a pressing member 702 and a rotating drum 703, and the pressing member 702 includes a sleeve 7022 and a pressing rod 7021 sleeved in the sleeve 7022, and the pressing rod 7021 is connected to the sleeve 7022 through a first spring 7023, and the rotating drum 703 is connected to a connecting rod 704, and the connecting rod 704 is connected to the bottle cap 2, and a first spiral groove 7031 is provided on the inner wall of the rotating drum 703, and a limiting column 7024 is correspondingly provided on the pressing rod 7021.

[0026] It should be noted that the rotating drum 703 is rotatable. During actual use, the pressing rod 7021 is pressed, and the limiting column 7024 moves downward with the pressing rod 7021. At this time, the limiting column 7024 cooperates with the first spiral groove 7031 to make the rotating drum 703 rotate, so that the connecting rod 704 drives the bottle cap 2 to rotate with the rotating drum 703 as the axis, so that the medicine storage bottle 1 is opened, so that the medicine adding or changing operation can be carried out. It is easy to use and can also avoid the loss of the bottle cap. In addition, during the rotation of the bottle cap 2, the top surface of the opening of the medicine storage bottle 1 can scrape the bottom surface of the bottle cap 2. In this way, the medicine liquid remaining on the bottom surface of the bottle cap 2 can be scraped off to prevent the medicine liquid from dripping on the body.

[0027] In a specific implementation manner, Figure 3 As shown, the pressing rod 7021 is provided with a pressing cap 7025, and the pressing cap 7025 is provided with at least one set of limiting blocks 7026. A limiting plate 7032 is provided in the rotating drum 703, and the limiting plate 7032 is provided with limiting holes 7033 for the limiting blocks 7026 to pass through. Under normal circumstances, the limiting blocks 7026 are located above the limiting plates 7032.

[0028] For easy observation, an opening may be provided on the top of the rotating drum 703, or the cover may be made of transparent material such as glass. Figure 3 , Figure 6 The middle ones are all open settings.

[0029] The pressing cap 7025 is provided with a clamping member 8, and the clamping member 8 is used to fix the pressing cap 7025;

[0030] The upper end of the first spiral groove 7031 is connected to the second vertical groove 7034 .

[0031] In the above technical solution, the length of the second vertical groove 7034 should be greater than or equal to the thickness of the limiting plate 7032 , so that the rotating drum 703 will not rotate before the limiting block 7026 passes through the limiting hole 7033 .

[0032] In a specific implementation manner, Figure 4-Figure 5 As shown, the clamping member 8 includes a clamping ball 801, which is fixedly connected to the side wall of the pressing rod 7021 through a second spring 802. A through hole 7028 is correspondingly opened on the side wall of the pressing cap 7025, and the clamping ball 801 is arranged in the through hole 7028.

[0033] Under normal circumstances, the limit block 7026 is above the limit plate 7032, and the locking ball 801 is inserted into the through hole 7028. When the medicine storage bottle 1 needs to be opened, the locking ball 801 is manually pressed into the through hole 7028, and then the pressing cap 7025 is rotated to align the limit block 7026 with the limit hole 7033, and then the pressing cap 7025 is pressed. Through the mutual cooperation between the limit column 7024 and the first spiral groove 7031, the rotating drum 703 rotates, so that the connecting rod 704 drives the bottle cap 2 to rotate with the rotating drum 703 as the rotating axis, so that the medicine storage bottle 1 is opened. This setting can prevent the bottle cap 2 from opening due to accidental touch.

[0034] In another embodiment, if Figure 6-Figure 7 As shown, the top surface of the bottle cap 2 is connected to the lower bottom surface of the connecting rod 704 , and the size of the bottle cap 2 is adapted to the inner diameter of the medicine storage bottle 1 .

[0035] In a specific implementation, a movable plate 7036 is provided in the shell 6, and the movable plate 7036 is fixedly connected to the bottom of the shell 6 through an elastic member. A circular groove is provided on the upper surface of the movable plate 7036, and the lower end of the rotating drum 703 is arranged in the circular groove. In actual use, the rotating drum 703 can rotate in the circular groove.

[0036] In a specific implementation, a slide groove 7029 is provided on the pressing cap 7025, and the slide groove 7029 includes a second spiral groove 7027, the upper end of the second spiral groove 7027 is connected to a first vertical groove 7038, and the first vertical groove 7038 is connected to an arc groove 7039, and a limiting rod 7037 matching the slide groove 7029 is correspondingly provided on the rotating drum 703.

[0037] In a specific implementation, the elastic member is a third spring 7035 .

[0038] Under normal circumstances, the third spring 7035 is in a compressed state, the bottle cap 2 is covered on the inside of the medicine storage bottle 1, and the limiting column 7024 is in the second vertical groove 7034. When in use, the card receiving ball 801 is manually pressed into the through hole 7028, and then the pressing cap 7025 is rotated, the limiting rod 7037 moves upward along the second spiral groove 7027, the elastic force of the third spring 7035 is released, and when the limiting rod 7037 moves to the bottom of the first vertical groove 7038, the limiting block 7026 is aligned with the limiting hole 7033, and the bottle cap 2 is just lifted out of the medicine storage bottle 1. At this time, the third spring 7035 is in a normal state, and then the pressing cap 7025 is pressed to make the limiting block 7026 pass through the limiting hole 7033. In this process, the limiting rod 7037 and the limiting column 7024 are respectively in the first vertical groove 7038. When the stop block 7026 completely passes through the stop hole 7033, the stop rod 7037 and the stop column 7024 are respectively at the top of the first vertical groove 7038 and the top of the second vertical groove 7034, and continue to press the pressing cap 7025. During the rotation process, the stop rod 7037 moves in the arc groove 7039, and the stop column 7024 cooperates with the first spiral groove 7031 to make the rotating drum 703 rotate, so that the connecting rod 704 drives the bottle cap 2 to rotate with the rotating drum 703 as the rotating axis, so that the medicine storage bottle 1 is opened. It should be noted that the elastic coefficient of the third spring 7035 is greater than the elastic coefficient of the first spring 7023, so that when the stop column 7024 moves in the first spiral groove 7031, the third spring 7035 will not be compressed, and the rotation of the rotating drum 703 can be realized;

[0039] It should be noted that the unfolded length of the third spring 7035 after releasing the elastic force is equal to the thickness of the bottle cap 2, that is, when the third spring 7035 releases the elastic force, the bottle cap 2 just rises out of the medicine storage bottle 1, and when the bottle cap 2 rotates, the bottle mouth of the medicine storage bottle 1 can just scrape the bottom surface of the bottle cap 2.

[0040] In a specific implementation manner, a sealing ring is arranged around the bottle cap 2 .

[0041] The sealing ring can be made of rubber material to improve the sealing performance of the medicine storage bottle 1.

[0042] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
