Description

Technical Field

[0001] This utility model relates to the field of chestnut planting technology, specifically to a tracked trenching and fertilizing machine for chestnut orchards in mountainous areas. Background Technology

[0002] In the mountain chestnut planting industry, trenching and fertilization are key steps to ensure the healthy growth of chestnut trees and increase yield. Trenching and fertilization equipment is often needed in the process of trenching and fertilization.

[0003] Patent CN223053414U discloses a trenching and fertilizing machine for fruit tree planting, including a handle, a drive assembly providing rotational power fixedly connected to the top of the outer shell, a rotating column fixedly connected to the drive assembly, a drive wheel fixedly connected to the outside of the rotating column, a belt sleeved on the outside of the drive wheel, a driven wheel rotatably connected inside the belt, a power assembly providing rotational force fixedly connected inside the protective shell, a rotating column fixedly connected to the power assembly, and a feed inlet fixedly connected to the top of the transport pipe.

[0004] Although this device solves the problem of some devices being unable to quantitatively apply organic fertilizer, and allows the soil to be leveled by the flat plate after the fertilizer has been applied, thus solving the problem of some devices being unable to store the flat plate, the multiple plow-like structures on the outer wall of the tillage column in this device are fixed and the distance between each pair of adjacent plow-like structures cannot be adjusted. Therefore, the distance between each pair of adjacent ditches cannot be adjusted according to planting needs. At the same time, the device has poor mobility and is difficult to adapt to complex mountainous environments. In view of this, we propose a tracked ditching and fertilizing machine for chestnut orchards in mountainous areas. Utility Model Content

[0005] The purpose of this utility model is to provide a tracked trenching and fertilizing machine for chestnut orchards in mountainous areas. By designing an electric cylinder and adjustable trenching components in the trenching and fertilizing mechanism, it solves the problem that the height and spacing of the plow blades are inconvenient to adjust and difficult to adapt to different planting requirements. Through the fertilizing components and related accessories, it solves the problems of inaccurate fertilization and easy waste.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A tracked ditching and fertilizing machine for chestnut orchards in mountainous areas includes a tracked vehicle body. A mounting plate is installed on the right side surface of the tracked vehicle body near the top. A ditching and fertilizing mechanism is provided on the bottom surface of the mounting plate. The ditching and fertilizing mechanism includes a lifting plate located below the mounting plate and an electric cylinder mounted on the top surface of the mounting plate for driving the lifting plate to move up and down. The ditching and fertilizing mechanism also includes:

[0008] An adjustable trenching assembly is installed on the bottom surface of a lifting plate and is used to trench the soil. The adjustable trenching assembly includes two fixed plates fixed on the bottom surface of the lifting plate, two movable plates located on the bottom surface of the lifting plate, two plow blades installed on the bottom surface of the movable plates on the same side, a bidirectional screw rotatably connected between the two fixed plates and used to drive the two movable plates to move, and a connecting plate is fixed on the right side surface of the movable plates.

[0009] Two fertilization components are respectively installed on the outer right side of the two connecting plates for fertilizing the opened trenches. The fertilization components include a fertilization cylinder, a feeding funnel fixed on the top surface of the feeding funnel, and a discharge pipe fixed on the bottom surface of the fertilization cylinder.

[0010] In a preferred embodiment, the cylinder body of the electric cylinder is mounted on the top surface of the mounting plate, the piston rod of the electric cylinder passes through the top surface of the mounting plate and extends to the bottom of the mounting plate, and the lifting plate is fixed on the bottom surface of the piston rod of the electric cylinder.

[0011] In a preferred embodiment, the fixed plate is installed on the bottom surface of the lifting plate from front to back. The adjustable trenching assembly also includes two rotating columns that are rotatably connected to the two fixed plates respectively, a motor installed on the outer wall of one of the fixed plates and whose output shaft is coaxially connected to the rotating column on the same side, the bidirectional lead screw is coaxially fixed between the two rotating columns and arranged from front to back, the moving plate is threadedly connected to the bidirectional lead screw, and the two moving plates are symmetrically arranged on the outer circumferential wall of the bidirectional lead screw.

[0012] In a preferred embodiment, the bottom surface of the lifting plate is provided with a guide groove arranged in a front-to-back manner, and the top surface of the movable plate is fixed with a guide block that is slidably connected to the guide groove on the bottom surface of the lifting plate.

[0013] In a preferred embodiment, the longitudinal cross-sectional shape of the guide groove on the bottom surface of the lifting plate is convex, and the shape of the guide block is convex, which matches the shape of the guide groove on the bottom surface of the lifting plate.

[0014] These four settings allow for adjustable plow blade height, adjustable spacing between the two plow blades, more direct and stable lifting drive of the lifting plate, precise adjustment of plow blade height, synchronous and reverse movement of the two moving plates, efficient and stable adjustment of plow blade spacing, smoother movement of the moving plates, avoidance of deviation affecting trenching accuracy, and reduced likelihood of the moving plates detaching from the lifting plate during movement, thus improving structural stability.

[0015] In a preferred embodiment, the feeding funnel and the unloading pipe are both connected to the inner cavity of the fertilizer cylinder on the same side. A manual valve is installed on the outer wall of the feeding funnel, and a solenoid valve is installed on the outer wall of the unloading pipe.

[0016] In a preferred embodiment, a sealing ring is provided at the part of the fertilizer cylinder that contacts the feed funnel tube on the same side, and a sealing ring is also provided at the part of the discharge pipe that contacts the fertilizer cylinder on the same side.

[0017] In a preferred embodiment, the bottom of the fertilizer cylinder has a structure that is concave from all sides to the center, and the position of the discharge pipe corresponds to that of the plow blade on the same side and the size is compatible.

[0018] These three settings, through the configuration of the fertilizer application component, enable fertilizer to be applied into the prepared trenches, enhance the sealing of the fertilizer application component to prevent fertilizer leakage and waste, and allow fertilizer to fall more smoothly into the corresponding trenches, thereby improving the accuracy of fertilization.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] 1. This utility model, through the setting of the tracked vehicle body, realizes the flexible movement of the entire device in complex mountainous environments. It is especially suitable for chestnut orchards on mountainous terrain where large machinery is difficult to access. Its tracked design increases the contact area with the ground, reduces the pressure per unit area, and improves the passability on soft or rugged terrain, achieving the effect of adapting to various mountainous conditions. At the same time, the mounting plate provides a stable mounting foundation for the ditching and fertilizing mechanism, ensuring that the ditching and fertilizing mechanism can work normally during the movement of the device.

[0021] 2. The electric cylinder, adjustable ditching component, and fertilization component in this utility model's ditching and fertilization mechanism work together to achieve diversified and precise ditching and fertilization operations. The electric cylinder can precisely control the lifting and lowering of the lifting plate, thereby flexibly adjusting the depth of the plow blades into the soil to meet the needs of different chestnut planting depths. The bidirectional screw in the adjustable ditching component, driven by a motor, can synchronously adjust the position of the two moving plates, changing the distance between the two plow blades. This allows for flexible adjustment of the distance between adjacent ditches according to the planting spacing of chestnut trees, achieving a precise ditching effect. In addition, the fertilization component, corresponding to the position of the plow blades, can promptly and accurately apply fertilizer into the ditch after it is dug, avoiding fertilizer waste and uneven distribution, improving fertilizer utilization, and reducing the labor intensity of manual fertilization, achieving a highly efficient and precise fertilization effect.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0031] Please see Figures 1-5 The present invention provides a technical solution: a tracked ditching and fertilizing machine for chestnut orchards in mountainous areas, including a tracked vehicle body 1, an installation plate 2 installed on the right side surface of the tracked vehicle body 1 near the top, a ditching and fertilizing mechanism 3 provided on the bottom surface of the installation plate 2, the ditching and fertilizing mechanism 3 including a lifting plate 31 located below the installation plate 2, an electric cylinder 32 installed on the top surface of the installation plate 2 and used to drive the lifting plate 31 to lift. The ditching and fertilizing mechanism 3 also includes: an adjustable ditching component 34, set on the bottom surface of the lifting plate 31, used to ditch the soil, the adjustable ditching component 34 including two fixed plates 341 fixed on the bottom surface of the lifting plate 31, two moving plates 345 located on the bottom surface of the lifting plate 31, two plow blades 347 installed on the bottom surface of the moving plates 345 on the same side, a bidirectional screw 343 rotatably connected between the two fixed plates 341 and used to drive the two moving plates 345 to move, and a connecting plate 33 fixed on the right side surface of the moving plate 345.

[0032] The tracked vehicle body 1 enables the device to move across complex terrain in the hillside chestnut orchard; the mounting plate 2 ensures the stable installation of the ditching and fertilizing mechanism 3; the lifting plate 31 and electric cylinder 32 allow the height of the plow blades 347 to be adjusted; the bidirectional lead screw 343 of the adjustable ditching component 34 allows the distance between the two plow blades 347 to be adjusted; and the fertilizing component 35 ensures that fertilizer is precisely applied into the ditch.

[0033] The cylinder body of the electric cylinder 32 is mounted on the top surface of the mounting plate 2, the piston rod of the electric cylinder 32 passes through the top surface of the mounting plate 2 and extends to the bottom of the mounting plate 2, and the lifting plate 31 is fixed on the bottom surface of the piston rod of the electric cylinder 32.

[0034] By using a specific installation method for the electric cylinder 32, the cylinder body is fixed and the piston rod is connected to the lifting plate 31, making the lifting drive direct and stable, ensuring that the height adjustment of the plow blade 347 is precise, meeting the needs of different trenching depths, and improving operational adaptability.

[0035] The fixed plate 341 is installed on the bottom surface of the lifting plate 31 from front to back. The adjustable trenching assembly 34 also includes two rotating columns 342 that are rotatably connected to the two fixed plates 341 respectively, a motor 344 installed on the outer wall of one of the fixed plates 341 and whose output shaft is coaxially connected to the rotating column 342 on the same side, a bidirectional lead screw 343 coaxially fixed between the two rotating columns 342 and arranged from front to back, and a moving plate 345 threadedly connected to the bidirectional lead screw 343, and the two moving plates 345 are symmetrically arranged on the outer circumferential wall of the bidirectional lead screw 343.

[0036] By cooperating with the fixed plate 341, rotating column 342, motor 344 and bidirectional lead screw 343, the motor drives the lead screw to rotate, so that the two moving plates 345 move synchronously in opposite directions, so that the spacing of the plow blades 347 can be adjusted efficiently and smoothly to adapt to different planting spacings.

[0037] The bottom surface of the lifting plate 31 is provided with a guide groove arranged in a front-to-back manner, and the top surface of the moving plate 345 is fixed with a guide block 346 that is slidably connected to the guide groove on the bottom surface of the lifting plate 31.

[0038] By using the bottom guide groove of the lifting plate 31 and the top guide block 346 of the moving plate 345, the moving plate 345 slides along the groove when it moves, avoiding deviation, ensuring a regular trenching trajectory, improving trenching accuracy, and reducing rework.

[0039] The longitudinal cross-sectional shape of the guide groove on the bottom surface of the lifting plate 31 is convex, and the shape of the guide block 346 is convex, which matches the shape of the guide groove on the bottom surface of the lifting plate 31.

[0040] The connection stability is increased by using the U-shaped guide groove and the matching U-shaped guide block 346, so that the moving plate 345 is not easy to detach from the lifting plate 31 when it moves, ensuring smooth trenching operation and reducing the probability of failure.

[0041] In this embodiment, as Figures 1-3 , Figure 6 As shown, the trenching and fertilizing mechanism 3 also includes two fertilizing components 35, which are respectively set on the right outer wall of the two connecting plates 33, for fertilizing the trenches. The fertilizing component 35 includes a fertilizing cylinder 351, a feeding funnel 352 fixed on the top surface of the feeding funnel 352, and a discharge pipe 354 fixed on the bottom surface of the fertilizing cylinder 351.

[0042] Both the feed hopper 352 and the discharge pipe 354 are connected to the inner cavity of the fertilizer cylinder 351 on the same side. A manual valve 353 is installed on the outer wall of the feed hopper 352, and a solenoid valve 355 is installed on the outer wall of the discharge pipe 354.

[0043] The feed hopper 352 and discharge pipe 354 are connected to the fertilizer cylinder 351. With the help of manual valve 353 and solenoid valve 355, fertilizer addition is convenient and discharge is controllable, enabling precise adjustment of fertilizer application and reducing waste.

[0044] A sealing ring is provided at the part where the fertilizer cylinder 351 contacts the pipe body of the feed funnel 352 on the same side, and a sealing ring is also provided at the part where the discharge pipe 354 contacts the fertilizer cylinder 351 on the same side.

[0045] The sealing rings at the contact points between the fertilizer applicator 351, the feed hopper 352, and the discharge pipe 354 enhance the sealing of the connection, prevent fertilizer leakage, ensure fertilizer utilization, and reduce operating costs.

[0046] The bottom of the fertilizer cylinder 351 is concave from all sides to the center, and the position of the discharge pipe 354 corresponds to the position of the plow blade 347 on the same side and the size is compatible.

[0047] The concave structure at the bottom of the fertilizer cylinder 351 makes it easy for fertilizer to accumulate; the matching of the discharge pipe 354 and the plow blade 347 allows the fertilizer to fall precisely into the corresponding ditch, improving the accuracy of fertilization and helping chestnut growth.

[0048] It should be added that the electric cylinder 32, the motor 344, and the two solenoid valves 355 are all electrically connected to the external PLC and the external power supply via wires, and the external PLC is also electrically connected to the external power supply via wires.

[0049] Finally, it should be noted that the tracked vehicle body 1, electric cylinder 32, motor 344, two solenoid valves 355 and other components involved in this utility model are all general standard parts or components known to those skilled in the art. Their structure and principle can be known to those skilled in the art through technical manuals or conventional experimental methods. In the idle space of this device, all the above-mentioned electrical components, which refer to power elements, electrical components and adapted controllers and power supplies, are connected by wires. The specific connection method should refer to the working principle of this utility model. The electrical connections between each electrical component are completed in the order of operation. The detailed connection methods are all technologies known in the art.

[0050] In this embodiment, during actual use, the external PLC controls the electric cylinder 32 to start, driving the lifting plate 31 to descend, so that the plow blade 347 contacts the soil and reaches the preset depth, after which the PLC controls the electric cylinder 32 to stop running.

[0051] Next, the PLC controls the motor 344 to start, and the motor 344 drives the rotating column 342 and the bidirectional lead screw 343 to rotate, so that the two moving plates 345 move along the guide groove of the lifting plate 31. After adjusting the distance between the two plow blades 347 to the preset value, the PLC controls the motor 344 to stop.

[0052] When the tracked vehicle body 1 moves, the plow blade 347 opens the ditch, and at the same time, the PLC controls two solenoid valves 355 to open, and the fertilizer in the fertilizer cylinder 351 falls into the corresponding ditch through the unloading pipe 354; when fertilization needs to be stopped, the PLC controls the solenoid valve 355 to close.

[0053] When the trenching depth needs to be adjusted, the PLC controls the electric cylinder 32 to run; when feeding, the manual valve 353 of the feeding funnel 352 is manually opened to add fertilizer. The entire process is coordinated by the PLC to complete the trenching and fertilization operation.

[0054] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
