Description

Technical Field

[0001] This utility model relates to the field of crop root irrigation technology, and in particular to an irrigation device for greenhouse crop root diseases. Background Technology

[0002] In intensive agricultural production such as greenhouses, root diseases are a key factor affecting crop yield and quality. For these diseases, root drenching with pesticides directly applied to the crop roots is widely recognized as the most direct and efficient control method. Specialized root drenching equipment is typically required for this operation.

[0003] The effectiveness of root drenching is closely related to whether the pesticide solution can be accurately delivered to the main root distribution area of ​​the crop. This means that the depth of drenching is a key parameter that determines the success or failure of pest control. If the drenching depth is too shallow, the pesticide solution will easily remain in the surface soil, making it difficult for the roots to absorb effectively and potentially resulting in loss due to evaporation. If the drenching depth is too deep, it will bypass the main root zone, wasting the pesticide solution and failing to achieve the desired control effect.

[0004] However, common root sprayers in existing technologies often lack stable and reliable depth adjustment and positioning mechanisms. Operators mostly rely on personal experience and visual estimation to control the depth of the spray needle insertion into the soil. This method is not only cumbersome and inefficient, but more seriously, it makes it difficult to ensure consistent spraying depth for every crop, resulting in inconsistent overall control effects and affecting the accuracy and standardization of pesticide application.

[0005] Therefore, this utility model proposes a greenhouse crop root disease irrigation device to address the shortcomings of existing technologies. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides a greenhouse crop root disease irrigation device, which aims to improve the problems of existing greenhouse crop root disease irrigation devices, such as irrigation depth relying on manual experience, inconvenient adjustment, and unreliable positioning, resulting in unstable pesticide application effects.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A greenhouse crop root disease irrigation device includes a support frame, a liquid pipe installed inside the support frame, and a height plate that can slide up and down along the support frame; the irrigation device is also equipped with a height adjustment and locking mechanism, which consists of a rotating wheel, a sliding rod, a handwheel, and a sliding block.

[0009] The rotating wheel is rotatably connected to the bracket and is connected to the height plate via a transmission to drive the height plate to move up and down.

[0010] Furthermore, the sliding rod is rotatably and axially slidably mounted on the bracket, the handwheel is fixedly connected to one end of the sliding rod, and the sliding block is fixedly connected to the sliding rod; when the handwheel drives the sliding rod to rotate, the sliding block rotates accordingly and drives the rotating wheel to rotate, thereby adjusting the position of the height plate; when the handwheel drives the sliding rod to slide axially, the sliding block switches between a locked position that can lock the rotating wheel and an unlocked position that can release the rotating wheel.

[0011] Preferably, the height plate is provided with a slot, and the outer circumference of the wheel is provided with multiple round rods. The round rods slide in the slot, thereby converting the rotational motion of the wheel into the vertical linear motion of the height plate.

[0012] Preferably, when the sliding block is in the locked position, its front end engages between two adjacent round rods on the rotating wheel.

[0013] Preferably, the medicine dispenser also includes a fixing frame, and the lower part of the support is fixedly connected to the fixing frame.

[0014] Preferably, the applicator further includes a wheel frame rotatably connected to the fixed frame, and wheels mounted on the wheel frame.

[0015] Preferably, the wheel frame rotates on a fixed frame about a horizontal axis so that the wheel can switch between a moving position supporting the medicine dispenser and a retracted position that does not contact the ground.

[0016] Preferably, the liquid tube is equipped with a switch for controlling the flow of the liquid.

[0017] Preferably, the lower end of the support is connected to a needle for injecting the medicine into the soil, and the medicine tube is connected to the needle.

[0018] This utility model has the following beneficial effects:

[0019] 1. In this utility model, a height adjustment and locking mechanism is set up by linking a handwheel, a sliding block, and a rotating wheel. This mechanism drives the height plate in contact with the ground to move up and down and can be reliably locked. This solves the problem of complex drug depth adjustment and inaccurate positioning in the prior art, which leads to unstable drug application effect. It achieves rapid and accurate adjustment of drug depth, ensures the consistency and reliability of working depth, and improves the technical effect of drug application.

[0020] 2. In this utility model, by setting a rotatable and retractable wheel frame and wheels, the problems of inconvenience in moving the medicine dispenser in greenhouses and other work sites and the high labor intensity in the prior art are solved. The technical effect of making the equipment easy to move and saving labor is achieved, which greatly reduces the labor intensity of users and can be switched to a stable working state, thereby improving the convenience of operation and the overall work efficiency.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please refer to Figures 1 to 5 This utility model provides a greenhouse crop root disease irrigation device, which aims to solve the problems of complex operation for adjusting irrigation depth, inaccurate positioning, and high labor intensity caused by inconvenient equipment movement in the existing technology.

[0030] like Figure 1 , Figure 2 and Figure 4As shown, the greenhouse crop root disease irrigation device includes a support 2, which serves as the main frame of the entire device, and a fixed frame 10 fixedly connected to the lower part of the support 2. The support 2 has a liquid pipe 1 for conveying liquid medicine inside. The lower end of the support 2 is connected to a needle for injecting liquid medicine into the soil. The liquid pipe 1 is connected to the needle. A switch 3 for controlling the on and off of liquid medicine is also installed on the liquid pipe 1. The irrigation device also includes a height plate 4 that can be slidably set on the support 2. The height plate 4 determines the irrigation depth of the irrigation device by contacting the ground. In order to achieve precise adjustment and reliable locking of the position of the height plate 4, the irrigation device is also equipped with a height adjustment and locking mechanism, which includes a rotating wheel 7, a sliding rod 9, a handwheel 5, and a sliding block 6.

[0031] Specifically, the rotating wheel 7 is rotatably connected to the bracket 2, the height plate 4 is provided with a slot 8, and the outer circumference of the rotating wheel 7 is provided with multiple round rods. The round rods of the rotating wheel 7 slide in cooperation with the slots 8 of the height plate 4. Through this transmission connection method, the rotational motion of the rotating wheel 7 can be converted into the vertical linear motion of the height plate 4, thereby adjusting its height. The sliding rod 9 is rotatably and axially slidingly mounted on the bracket 2. The handwheel 5 is fixedly connected to one end of the sliding rod 9. The operator can drive the sliding rod 9 to rotate or slide axially by operating the handwheel 5. The sliding block 6 is fixedly connected to the sliding rod 9, so the sliding block 6 will rotate or slide along with the sliding rod 9. Axial sliding: When adjusting the height, the operator turns the handwheel 5, which drives the sliding rod 9 to rotate. The sliding rod 9 then drives the sliding block 6 to rotate, which in turn drives the rotating wheel 7 to rotate, thereby realizing the lifting and lowering adjustment of the height plate 4. After the adjustment is completed, the operator pushes and pulls the handwheel 5 to cause the sliding rod 9 and the sliding block 6 to undergo axial displacement. The sliding block 6 can switch between a locked position that can lock the rotating wheel 7 and an unlocked position that can release the rotating wheel 7. In the locked position, the front end of the sliding block 6 is engaged between two adjacent round rods on the rotating wheel 7, thereby restricting the rotation of the rotating wheel 7 and thus stably fixing the height plate 4 in the adjusted position.

[0032] To further enhance the ease of use of the equipment in a greenhouse environment, the greenhouse crop root disease sprayer also includes a retractable mobile device, which consists of a wheel frame 11 and wheels 12 mounted on the wheel frame 11. The wheel frame 11 and the aforementioned fixed frame 10 form a specific rotational connection, thereby enabling the entire sprayer to switch between a stable operating state and a convenient mobile state.

[0033] Please refer to the following carefully. Figure 4 and Figure 5 The structure of this mobile device will be described in detail below:

[0034] The fixed frame 10 serves as the bottom support structure of the entire device. The wheel frame 11 is rotatably connected to both sides of the fixed frame 10 via a horizontally set pivot. The wheel 12 is installed at the end of the wheel frame 11 away from the rotatable connection end. In this way, the wheel frame 11 can rotate up and down around the horizontal axis on the fixed frame 10, thereby driving the wheel 12 to move between two different working positions. The first position is the moving position. In this position, the wheel frame 11 rotates downward, so that the wheel 12 contacts the ground and supports the entire applicator. At this time, the user can easily push the device to move a long distance. The second position is the folded position. In this position, the wheel frame 11 rotates upward, so that the wheel 12 leaves the ground and is stored on the side of the device. At this time, the entire applicator is stably supported on the ground by the fixed frame 10 and the bottom of the bracket 2, ensuring that the device will not shake or shift when performing root application, thus ensuring the accuracy of the operation. This switchable structure cleverly solves the contradiction between the convenience of moving the device and the stability during operation.

[0035] Based on the above embodiments, the present invention may further include the following preferred technical solutions:

[0036] As a preferred implementation of the height adjustment locking mechanism, the slot 8 on the height plate 4 is a vertically elongated through slot. Multiple round rods are uniformly fixedly connected to the outer circumference of the rotating wheel 7. The two ends of each round rod extend into the slot 8 of the height plate 4 and can slide along the length of the slot 8. When the rotating wheel 7 rotates, the round rods move up and down in the slot 8, driving the height plate 4 to move up and down synchronously, thereby achieving height adjustment. When locking is required, the sliding block 6 moves axially, and its front end can accurately engage in the gap formed between two adjacent round rods on the rotating wheel 7. This mechanical limiting method achieves reliable locking of the rotating wheel 7.

[0037] As a preferred embodiment, in order to facilitate the user's control of the supply of medicine, a switch 3 is provided on the medicine pipe 1. The switch 3 can be installed on the bracket 2 in a position that is easy to operate with one hand, such as near the handwheel 5. The switch 3 can be a ball valve or a push-button valve to realize the rapid opening and closing of the flow of medicine.

[0038] As another preferred embodiment, a needle for injecting medicine into the soil is fixedly connected to the lower end of the support 2. The needle has a hollow structure, with its upper end sealed and connected to the medicine tube 1 inside the support 2, and its lower end has a sharp conical structure to facilitate insertion into the soil. Multiple liquid outlet holes can be opened on the side wall of the needle so that the medicine can be more evenly dispersed into the soil around the crop roots.

[0039] Working principle: Before administering the medicine, the height is first adjusted. The operator pulls the handwheel 5 outward, which drives the sliding rod 9 and the fixedly connected sliding block 6 to move axially to the unlock position, separating the sliding block 6 from the rotating wheel 7. Then, the handwheel 5 is rotated, which drives the rotating wheel 7 to rotate through the sliding rod 9 and the sliding block 6. Since the round rod on the rotating wheel 7 slides in the slot 8 on the height plate 4, the rotation of the rotating wheel 7 drives the height plate 4 to move up and down along the vertical direction of the bracket 2. When the height plate 4 is adjusted to the position corresponding to the required medicine depth, the operator stops rotating the handwheel 5 and pushes the handwheel 5 inward, causing the sliding block 6 to move axially to the locking position. Its front end engages between two adjacent round rods on the rotating wheel 7, thereby locking the rotating wheel 7. At this time, the height of the height plate 4 is fixed.

[0040] When applying pesticide, move the pesticide applicator next to the crop so that the bottom of the height plate 4 contacts the ground. At this time, the needle at the lower end of the bracket 2 will accurately reach the preset root depth. Turn on the switch 3, and the external pesticide will flow out through the pesticide tube 1 and be injected into the soil at the root of the crop through the needle. After completing the pesticide application for one crop, turn off the switch 3. When it is necessary to move the equipment over a long distance in the greenhouse, the wheel frame 11 can be flipped downward around the rotation connection point between it and the fixed frame 10 so that the wheels 12 contact the ground and support the entire equipment. The user can then easily push the equipment to move. After reaching the new work point, the wheel frame 11 can be flipped upward to fold it up and make the equipment stable.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
