Greenhouse track self-propelled inter-row weeding shovel

Abstract

This utility model relates to the field of greenhouse cultivation technology, and in particular to a self-propelled inter-plant weeding shovel with a greenhouse track. It includes a track laid between greenhouse plants, a movable cart movably mounted on its surface, a counterweight at the top of the cart, and connecting rods at both ends of the cart. A weeding shovel is fixedly connected to the end of each connecting rod furthest from the cart. The weeding shovel is used to remove weeds between greenhouse plants. An adjustment mechanism is provided between the connecting rods and the counterweight. This utility model allows the movable cart to move flexibly on the track, using the weeding shovels on both sides to precisely remove weeds between greenhouse plants, solving the problem of difficult operation of large weeding machinery in the narrow space of a greenhouse. A telescopic device pushes the weeding shovel to rotate, adapting to the weeding needs at different root depths. The counterweight at the top of the cart effectively prevents the cart from derailing due to reaction force when weeding deeper.

Description

Technical Field

[0001] This utility model relates to the field of greenhouse cultivation technology, specifically to a greenhouse track-mounted self-propelled weeding shovel for weeding between plants. Background Technology

[0002] In greenhouse agriculture, weed growth poses a serious threat to crop health and yield. Specifically, weeds compete with crops for limited nutrients, water, and light, leading to slow growth, poor development, and even reduced yields. While traditional manual weeding can control weeds to some extent, it is labor-intensive, inefficient, and difficult to apply widely in large-scale greenhouse cultivation. With the expansion of greenhouse cultivation and rising labor costs, manual weeding can no longer meet the demands of modern agriculture for high efficiency and low cost. Existing mechanized weeding technologies, while improving efficiency to some extent, are mostly designed for open fields and have many limitations in greenhouse environments. Firstly, traditional weeders are large in size, which poses challenges in greenhouse applications. The confined space of a greenhouse makes operation difficult, easily causing crop damage and equipment malfunction. Secondly, traditional weeders cannot accurately distinguish between crops and weeds, often using a "one-size-fits-all" approach, resulting in the accidental removal of crops and affecting crop yield. In addition, greenhouse floors are usually relatively flat, but the walking mechanisms of traditional weeders (such as large tires or tracks) are difficult to adapt to this specific environment, leading to unstable movement and poor weeding effect. Furthermore, the greenhouse environment places higher demands on weeding machinery. Due to the limited internal space and high crop planting density in greenhouses, weeding machinery needs to have greater flexibility and precision. At the same time, environmental factors such as humidity and temperature inside the greenhouse may also cause corrosion to mechanical components or affect their normal operation, increasing the difficulty of mechanical design and maintenance.

[0003] However, most weeding machines on the market cannot meet the above requirements at the same time; although some high-end intelligent weeding robots have high precision and flexibility, their high cost and complicated operation technology limit their widespread application in greenhouse agriculture.

[0004] Based on this, a self-propelled greenhouse track weeding shovel is provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0005] To address the aforementioned problems, a self-propelled greenhouse track-mounted weeding shovel is provided, which solves the problems through this new type of equipment.

[0006] To address the problems of existing technologies, this utility model provides a greenhouse track-mounted self-propelled weeding shovel, comprising a track laid between greenhouse plants, a movable trolley movably mounted on the surface, a counterweight at the top of the movable trolley, and connecting rods at both ends of the movable trolley. A weeding shovel is fixedly connected to the end of each connecting rod furthest from the movable trolley. The weeding shovel is used to remove weeds between greenhouse plants. An adjustment mechanism is provided between the connecting rods and the counterweight, and the adjustment mechanism is used to adjust the tilt angle of the weeding shovel.

[0007] Preferably, the adjustment mechanism includes a first hinge fixedly disposed on the side wall of the counterweight, the end of the first hinge away from the counterweight is connected to a telescopic device, the power end of the telescopic device is provided with a third hinge, and the end of the third hinge away from the telescopic device is connected to the surface of the connecting rod.

[0008] Preferably, a second hinge is provided on each side of the mobile vehicle, and the end of the second hinge away from the mobile vehicle is connected to the end of the connecting rod away from the weeding shovel.

[0009] Preferably, the first hinge includes a set of fixed blocks and two sets of movable blocks. The fixed blocks are fixedly disposed on the surface of the counterweight block, and the two sets of movable blocks are fixedly disposed at one end of the telescopic device. The fixed blocks are respectively provided with cylinders at both ends, and the two sets of movable blocks are provided with slots on their sidewalls, and the cylinders are respectively engaged with the slots located on both sides. The internal structures of the first hinge, the second hinge, and the third hinge are the same.

[0010] Preferably, the mobile vehicle is an electrically driven trolley.

[0011] The advantages of this utility model compared to the prior art are: This invention utilizes a mobile cart that moves flexibly along a track and employs weeding shovels on both sides to precisely remove weeds between greenhouse plants. This avoids the inefficiency and inaccuracy of traditional manual weeding and solves the problem of operating large weeding machinery in the confined space of a greenhouse. The weeding shovels can be tilted and rotated via a telescopic device, adjusting their angle to accommodate weeds at different root depths. This flexibility ensures more thorough weeding and effectively prevents weed regrowth. A counterweight at the top of the mobile cart prevents it from derailing due to reaction forces when weeding deeper, enhancing the stability and safety of the equipment. Compared to traditional manual weeding, this invention achieves mechanized weeding, significantly reducing labor intensity. Furthermore, the equipment is low-cost, simple to set up, and easy to promote and apply in large-scale greenhouse cultivation, contributing to lower overall production costs.

[0016] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0017] Example 1 This embodiment provides a greenhouse track-mounted self-propelled weeding shovel for weeding between plants, such as... Figures 1-3 As shown, the system includes a track 1 laid between greenhouse plants, a movable cart 2 movably mounted on the surface of the track 1, a counterweight 3 mounted on the top of the movable cart 2, connecting rods 5 mounted at both ends of the movable cart 2, and a weeding shovel 6 fixedly connected to the end of each connecting rod 5 away from the movable cart 2. The weeding shovel 6 is used to remove weeds between the greenhouse plants, and an adjustment mechanism 4 is provided between the connecting rod 5 and the counterweight 3. The adjustment mechanism 4 is used to adjust the tilt angle of the weeding shovel 6.

[0018] The mobile cart 2 moves within the track 1 and uses weeding shovels 6 on both sides of the cart 2 to remove weeds from the ground it passes over, thereby clearing weeds between greenhouse plants. Simultaneously, the telescopic device 8 pushes the weeding shovels 6 to rotate, thus clearing weeds at different root depths. Furthermore, a counterweight 3 at the top of the mobile cart 2 prevents it from detaching from the track 1 due to reaction force when the weeding shovels 6 are at a deeper depth. This invention is suitable for weeding between greenhouse plants and has the advantages of low cost and simple setup compared to existing technologies.

[0019] Based on Embodiment 1, the solution in Embodiment 1 will be further described in detail below, with reference to the specific working method described in detail: like Figures 1-3As shown, in a preferred embodiment, the adjustment mechanism 4 includes a first hinge 7 fixedly disposed on the side wall of the counterweight 3. The end of the first hinge 7 away from the counterweight 3 is connected to a telescopic device 8. The power end of the telescopic device 8 is provided with a third hinge 10. The end of the third hinge 10 away from the telescopic device 8 is connected to the surface of the connecting rod 5.

[0020] like Figures 1-3 As shown, in a preferred embodiment, the movable vehicle 2 is provided with a second hinge 9 on each side, and the end of the second hinge 9 away from the movable vehicle 2 is connected to the end of the connecting rod 5 away from the weeding shovel 6.

[0021] like Figures 1-3 As shown, in a preferred embodiment, the first hinge 7 includes a set of fixed blocks and two sets of movable blocks. The fixed blocks are fixedly disposed on the surface of the counterweight block 3, and the two sets of movable blocks are fixedly disposed at one end of the telescopic device 8. The fixed blocks are respectively provided with cylinders at both ends, and the two sets of movable blocks have slots on their side walls, and the cylinders are respectively engaged with the slots located on both sides. The internal structures of the first hinge 7, the second hinge 9, and the third hinge 10 are the same.

[0022] like Figures 1-3 As shown, in a preferred embodiment, the mobile vehicle 2 is an electrically driven vehicle.

[0023] The working principle is as follows: In use, this utility model involves a movable cart 2 moving within the track 1, using weeding shovels 6 on both sides of the cart 2 to remove weeds from the ground, thus clearing weeds between greenhouse plants. Simultaneously, the telescopic device 8 pushes the weeding shovels 6 to rotate, thereby clearing weeds at different root depths. Furthermore, a counterweight 3 at the top of the cart 2 prevents it from detaching from the track 1 due to reaction force when the weeding shovels 6 are at a deeper depth. This utility model is suitable for weeding between greenhouse plants and has the advantages of low cost and simple setup compared to existing technologies.

[0024] Example 2 S1 track laying: Inside the greenhouse, a dedicated track 1 is laid out according to the layout of the crop planting rows; The track must be flat and stable, and strictly aligned with the crop planting rows to provide a precise travel path for the subsequent mobile vehicle 2; S2 event vehicle preparation: An electrically driven trolley is selected as the mobile vehicle 2, ensuring that its wheels match the track 1 and can move flexibly on the track 1. A counterweight 3 is installed on the top of the mobile vehicle 2. The weight of the counterweight 3 needs to be precisely calculated to balance the reaction force generated by the weeding shovel 6 during operation and prevent the equipment from tipping over or derailing from the track 1. Installation of S3 weeding shovel 6 and connecting rod 5: Connecting rods 5 are installed at both ends of the mobile vehicle 2, and a weeding shovel 6 is fixedly connected to the end of each connecting rod 5 away from the mobile vehicle 2. The design of the weeding shovel 6 needs to take into account its adjustable contact angle with the ground to adapt to weeds in different growth stages; S4 Adjustment Mechanism 4 Settings: An adjustment mechanism 4 is installed between the connecting rod 5 and the counterweight 3. The mechanism includes a first hinge 7, a telescopic device 8 (such as an electric push rod or a hydraulic cylinder), and a third hinge 10. The first hinge 7 is fixed to the side wall of the counterweight 3. One end of the telescopic device 8 is connected to the first hinge 7, and the other end is connected to the connecting rod 5 through the third hinge 10. The telescopic device 8 can dynamically adjust the tilt angle of the weeding shovel 6 by telescopic movement. S5 Equipment Testing and Adjustment: Activate the telescopic device 8 and test its ability to push the connecting rod 5 to ensure it can cover the root depth range of the target weeds.

[0025] At the same time, check whether the rotation of the first hinge 7, the second hinge 9 and the third hinge 10 is smooth, and ensure that the weeding shovel 6 can freely rotate with the movement of the telescopic device 8. S6 Autonomous Movement and Weeding Operations: Connect the power supply to the mobile vehicle 2, and control the mobile vehicle 2 to move autonomously along the track 1 via remote control or preset program. The speed is set to 0.5-1m / s to balance efficiency and weeding accuracy. During the movement, the tilt angle of the weeding shovel 6 is adjusted by the telescopic device 8 according to the depth of the weed roots, so as to achieve precise weeding.

[0026] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
