Description

Technical Field

[0001] This utility model relates to the field of honeysuckle berry cultivation technology, specifically a novel soil loosening device for honeysuckle berry cultivation. Background Technology

[0002] Honeysuckle berries, as a small berry with high economic value, have specific requirements for soil conditions. Loose, well-aerated, and fertile soil promotes healthy root development, helps the plant absorb nutrients and water, and thus increases fruit yield and quality. In honeysuckle berry cultivation, maintaining proper soil condition is a crucial agricultural operation that directly affects the berry's growth and final yield.

[0003] Most soil loosening equipment currently on the market for honeysuckle berry cultivation uses traditional designs, which presents many problems that urgently need to be solved. Regarding the adjustment of tilling depth and angle, traditional equipment typically employs fixed structures or simple mechanical adjustment methods, which are cumbersome to operate and have a limited adjustment range. They are unable to flexibly adjust to the diverse needs of different terrains, soil textures, and different growth stages of honeysuckle berry for soil loosening. For example, when planting honeysuckle berry on slopes, traditional equipment cannot effectively adjust the tilling angle to adapt to the slope, resulting in uneven tilling. During the seedling stage, it is also difficult to control the tilling depth, easily damaging the seedling roots. Utility Model Content

[0004] The purpose of this invention is to provide a new type of soil loosening device for planting honeysuckle berries, which solves the technical problem of inconvenient adjustment of soil turning depth and angle in traditional soil loosening equipment. It achieves the goal of flexibly adapting to various planting conditions, comprehensively improving the soil loosening effect, and thus promoting the growth of honeysuckle berries, increasing yield and quality.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a novel soil loosening device for planting honeysuckle berries, comprising a loosening vehicle body, a soil turning wheel angle adjustment part, and a plowing blade telescopic lifting part. A counterweight is fixedly installed on the top outer wall of the loosening vehicle body, and a push handle is fixedly installed on the outer wall of the side with the counterweight. The soil turning wheel angle adjustment part is located on one outer wall of the loosening vehicle body. The plowing blade telescopic lifting part is located at the bottom of the loosening vehicle body.

[0006] Preferably, the soil turning wheel angle adjustment part specifically includes: a mounting groove symmetrically opened on the loosening vehicle body; a fixed shaft, respectively fixedly installed on the outer walls of both sides of the loosening vehicle body; and threaded positioning holes, circumferentially equidistantly opened on the outer wall of the loosening vehicle body.

[0007] Preferably, each of the mounting slots has a rotating shaft movably mounted inside, and each rotating shaft has a movable roller fixedly fitted on its outer wall. The movable rollers are respectively located on the outer walls of both sides of the loosening vehicle body, and each movable roller has equidistant grooves on its circumference. A rotating arm is movably fitted on the outer wall of the movable roller.

[0008] The device is equipped with movable rollers, which are fixed to a rotating shaft. The rotating shaft is movably installed in the mounting slot of the loosening vehicle body, providing good support for the loosening device. When the operator pushes the loosening vehicle body with counterweights and push handles, the movable rollers can roll easily, making it more convenient to move the device in the honeysuckle planting area. At the same time, since the movable rollers are distributed on both sides of the loosening vehicle body, it is convenient to operate in different terrains and planting areas, improving work efficiency.

[0009] Preferably, the rotating arms are respectively disposed on the outer walls of both sides of the loosened vehicle body, and positioning holes are equally spaced on the rotating arms. The positioning holes are adapted to the threaded positioning holes, and mudguards and fixed mounting blocks are respectively fixedly installed between the rotating arms.

[0010] Preferably, a round shaft is fixedly installed between the fixed mounting blocks, and a soil turning wheel is movably sleeved on the outer wall of the round shaft. A threaded positioning bolt is provided inside the positioning hole, and the threaded positioning bolt is threadedly connected to the threaded positioning hole through the positioning hole.

[0011] The system is equipped with positioning holes and threaded positioning holes. The positioning holes on the rotating arm are matched with the threaded positioning holes on the loosening vehicle body and are connected by threaded positioning bolts. When adjusting the angle of the turning wheel, the operator only needs to loosen the threaded positioning bolts and rotate the rotating arm connected to the fixed mounting block to drive the turning wheel to rotate around the circular shaft. Since the positioning holes and threaded positioning holes are equidistantly distributed around the circumference, multiple precise angle adjustment settings can be provided to meet the requirements of the turning wheel angle under different soil conditions and planting needs. For example, in soft soil, the turning wheel angle can be adjusted to a smaller angle to reduce the turning depth; in compacted soil, the angle can be adjusted to a larger angle to enhance the turning effect, ensuring the accuracy and efficiency of the turning operation.

[0012] Preferably, the plowing blade telescopic lifting part specifically includes: an adjustment channel, which is opened inside the loosening vehicle body; a fixing block, which is fixedly installed on the outer walls of both sides of the loosening vehicle body; a shaft, which is fixedly installed on the outer wall of the fixing block; and a storage slot, which is symmetrically opened at the bottom of the loosening vehicle body.

[0013] Preferably, the outer wall of the shaft is movably fitted with a movable sleeve one, and the outer wall of the movable sleeve one is respectively fixedly installed with a hydraulic telescopic rod one and a hydraulic telescopic rod two, and the telescopic ends of the hydraulic telescopic rod one and the hydraulic telescopic rod two are fixedly connected to the movable sleeve two.

[0014] Two hydraulic telescopic rods, Hydraulic Telescopic Rod One and Hydraulic Telescopic Rod Two, are installed. The telescopic ends of both rods are connected to a movable sleeve, which is fitted onto the connecting shaft of the L-shaped adjusting arm. When the height of the plowing blades needs to be adjusted, the angle of the L-shaped adjusting arm can be changed by controlling the extension and retraction of Hydraulic Telescopic Rod One and Hydraulic Telescopic Rod Two. This, in turn, causes the fixed connecting plate and the plowing blades to rise and fall synchronously. Because the hydraulic system provides stable and precise power output, it can achieve greater height adjustment compared to traditional mechanical adjustment methods, meeting the plowing operations under different soil depth requirements and ensuring the consistency of soil loosening depth.

[0015] Preferably, an adjusting shaft is movably installed inside the adjusting channel, and an L-shaped adjusting arm is fixedly sleeved on the outer wall of the adjusting shaft. The L-shaped adjusting arms are respectively arranged on both sides of the loosening vehicle body, and a connecting shaft is fixedly installed on the outer wall of each L-shaped adjusting arm. The movable sleeve is movably sleeved on the outer wall of the connecting shaft, and a fixed connecting plate is fixedly connected between the L-shaped adjusting arms. Plowing blades are fixedly installed at equal intervals on the top outer wall of the fixed connecting plate.

[0016] The system is equipped with plowing blades, which are fixedly mounted on a connecting plate. As the loosening vehicle moves, the plowing blades cut into the soil along with the L-shaped adjusting arm. Their sharp blades and reasonable spacing effectively break up hard lumps and compacted layers in the soil. In conjunction with hydraulic telescopic rods one and two, the depth of penetration of the plowing blades can be flexibly adjusted according to the soil compaction and tillage depth requirements. When encountering compacted soil, the hydraulic telescopic rods extend, allowing the plowing blades to penetrate deeper into the soil. With its powerful soil-breaking ability, it loosens the deep soil, enhances soil aeration and water permeability, creates a favorable soil environment for the growth of honeysuckle roots, and improves the overall quality of soil loosening.

[0017] This invention provides a novel soil loosening device for planting honeysuckle berries. It has the following beneficial effects:

[0018] (1) This utility model uses a rotating arm that is movably sleeved on the outer wall of a movable roller. The positioning holes on the rotating arm are equidistant from each other and are matched with the threaded positioning holes equidistant from each other on the circumference of the loosening vehicle body. The rotating arm is connected and fixed by a threaded positioning bolt. When it is necessary to adjust the soil turning depth, the threaded positioning bolt is loosened, the rotating arm is rotated to change the angle between the soil turning wheel and the ground, and then the threaded positioning bolt is tightened to fix it. For example, when loosening the soil in shallow soil, the angle of the soil turning wheel is reduced to make it fit the ground better and achieve fine turning of the shallow soil. When loosening the soil in deep soil, the angle of the soil turning wheel is increased to allow the soil turning wheel to penetrate into the soil and achieve the purpose of deep soil loosening, thus meeting the soil turning needs of different planting stages and soil conditions.

[0019] (2) This utility model adjusts the height and depth of the plowing blades by adjusting the rotation of the shaft in the adjusting groove, thereby driving the L-shaped adjusting arm to change the angle. At different stages of honeysuckle planting, such as the seedling stage when the root system is shallow, the plowing blades can be raised for shallow cultivation to avoid damaging the root system; the mature stage when the root system is well developed requires deeper soil loosening, so the height of the plowing blades is reduced to increase the cultivation depth, which meets the needs of honeysuckle growth for different soil loosening levels and promotes healthy root growth of the plant.

[0027] Example 1:

[0028] Addressing the inconvenience of adjusting the tilling depth and angle of traditional soil loosening equipment, this invention provides a preferred embodiment of a novel soil loosening device for honeysuckle berry cultivation, for example... Figures 1-4 As shown: A novel soil loosening device for planting honeysuckle berries includes a loosening vehicle body 1, a soil turning wheel angle adjustment part 3, and a plowing blade telescopic lifting part 4. A counterweight 2 is fixedly installed on the top outer wall of the loosening vehicle body 1, and a push handle is fixedly installed on the outer wall of the side with the counterweight 2. The soil turning wheel angle adjustment part 3 is located on the outer wall of one side of the loosening vehicle body 1.

[0029] The tillage wheel angle adjustment part 3 specifically includes: a mounting groove 311, symmetrically opened on the loosening vehicle body 1; a fixed shaft 315, respectively fixedly installed on the outer walls of both sides of the loosening vehicle body 1; and threaded positioning holes 314, circumferentially and equidistantly opened on the outer wall of the loosening vehicle body 1.

[0030] Rotating shafts 312 are movably installed inside the mounting slots 311. Moving rollers 313 are fixedly sleeved on the outer walls of the rotating shafts 312. The moving rollers 313 are respectively set on the outer walls of both sides of the loosening vehicle body 1. Grinding grooves are equidistantly opened on the circumference of the moving rollers 313.

When the L-shaped adjusting arm 415 rotates, it drives the fixed connecting plate 4113 and the plowing blade 416 installed on its top outer wall to change height. At the same time, the movable sleeve 4111 slides on the connecting shaft 4112. The connecting shaft 4112 is fixed to the outer wall of the L-shaped adjusting arm 415. If adjustment is required, the hydraulic telescopic rod 418 and the hydraulic telescopic rod 419 can be activated. One end of hydraulic telescopic rod 418 and hydraulic telescopic rod 419 is fixed to the outer wall of movable sleeve 417. Movable sleeve 417 is fitted onto shaft 414, which is installed on the outer wall of fixed block 413. Fixed block 413 is located on both sides of loosening vehicle body 1. The hydraulic telescopic rod extends and retracts, pushing movable sleeve 4111 to further fine-tune the soil penetration depth of plow blade 416, achieving fine turning of shallow soil. When turning deep soil, the angle of the turning wheel is increased, allowing the turning wheel to penetrate deeper into the soil, achieving the purpose of deep soil loosening and meeting the soil turning needs of different planting stages and soil conditions.

[0034] Example 2:

[0035] Please see Figures 1-4 Furthermore, based on Embodiment 1, the following is obtained: the plowing blade telescopic lifting part 4 specifically includes: an adjustment channel 411, which is opened inside the loosening vehicle body 1; a fixing block 413, which is fixedly installed on the outer walls of both sides of the loosening vehicle body 1; a shaft 414, which is fixedly installed on the outer wall of the fixing block 413; and a storage groove 412, which is symmetrically opened at the bottom of the loosening vehicle body 1.

[0036] The outer wall of the shaft 414 is movably fitted with a movable sleeve 417. The outer wall of the movable sleeve 417 is fixedly installed with a hydraulic telescopic rod 418 and a hydraulic telescopic rod 419. The telescopic ends of the hydraulic telescopic rods 418 and 419 are fixedly connected to the movable sleeve 4111.

[0037] An adjusting shaft 4114 is movably installed inside the adjusting channel 411. An L-shaped adjusting arm 415 is fixedly sleeved on the outer wall of the adjusting shaft 4114. The L-shaped adjusting arms 415 are respectively arranged on both sides of the loosening vehicle body 1. A connecting shaft 4112 is fixedly installed on the outer wall of each L-shaped adjusting arm 415. A movable sleeve 4111 is movably sleeved on the outer wall of the connecting shaft 4112. A fixed connecting plate 4113 is fixedly connected between the L-shaped adjusting arms 415. Plowing blades 416 are fixedly installed at equal intervals on the top outer wall of the fixed connecting plate 4113.

[0038] In this embodiment, according to the planting stage of honeysuckle berries and soil texture, the adjusting shaft 4114 inside the adjusting channel 411 is rotated. An L-shaped adjusting arm 415 is fixedly sleeved on the outer wall of the adjusting shaft 4114. When the L-shaped adjusting arm 415 rotates, it drives the fixed connecting plate 4113 and the plowing blade 416 installed on its top outer wall to change height. At the same time, the movable sleeve 4111 slides on the connecting shaft 4112. The connecting shaft 4112 is fixed to the outer wall of the L-shaped adjusting arm 415. If adjustment is required, the hydraulic telescopic rod 418 and the hydraulic telescopic rod 419 can be activated. One end of the second sleeve 419 is fixed to the outer wall of the movable sleeve 417. The movable sleeve 417 is fitted onto the shaft 414, which is installed on the outer wall of the fixed block 413. The fixed block 413 is located on both sides of the loosening vehicle body 1. The hydraulic telescopic rod extends and retracts, pushing the movable sleeve 4111 to further fine-tune the soil penetration depth of the plowing blade 416. During the seedling stage, the root system is relatively shallow, so the plowing blade can be raised for shallow cultivation to avoid damaging the root system. During the mature stage, the root system is well developed and requires deeper soil loosening. The height of the plowing blade is reduced to increase the cultivation depth, meeting the needs of honeysuckle berries for different soil loosening levels and promoting healthy root growth.

[0039] Working principle: When in use;

[0040] Step 1: Push the loosening vehicle body 1 to the work site, ensure that the counterweight 2 is firmly installed, and push the handle to make it easy to operate. Check whether the connections of each component of the tilling wheel angle adjustment part 3 and the plow blade telescopic lifting part 4 are tight, and whether the threaded positioning bolt 3111, hydraulic telescopic rod one 418 and hydraulic telescopic rod two 419 are working properly.

[0041] Step 2: Based on soil conditions and tillage requirements, loosen the threaded positioning bolt 3111. The threaded positioning holes 314, which are originally equidistant from the outer circumference of the loosening vehicle body 1, are threadedly connected through the positioning hole. Fix the rotating arm 317 and rotate it. The rotating arm 317 is movably sleeved on the outer wall of the movable roller 313. The movable roller 313 rotates in the mounting through slot 311 symmetrically opened on the loosening vehicle body 1 through the rotating shaft 312. The positions of the positioning hole and the threaded positioning hole 314 on the rotating arm 317 change. Adjust the angle between the soil turning wheel 319 and the ground. After the adjustment is completed, tighten the threaded positioning bolt 3111 to fix the rotating arm 317, thereby determining the angle of the soil turning wheel 319.

[0042] Step 3: Based on the planting stage of honeysuckle and soil texture, rotate the adjusting shaft 4114 inside the adjusting channel 411. An L-shaped adjusting arm 415 is fixedly sleeved on the outer wall of the adjusting shaft 4114. When the L-shaped adjusting arm 415 rotates, it drives the fixed connecting plate 4113 and the plowing blade 416 installed on its top outer wall to change height. At the same time, the movable sleeve 4111 slides on the connecting shaft 4112. The connecting shaft 4112 is fixed on the outer wall of the L-shaped adjusting arm 415. If adjustment is required, the hydraulic telescopic rod 418 and the hydraulic telescopic rod 419 can be activated. One end of the hydraulic telescopic rod 418 and the hydraulic telescopic rod 419 is fixed on the outer wall of the movable sleeve 417. The movable sleeve 417 is sleeved on the shaft 414. The shaft 414 is installed on the outer wall of the fixed block 413. The fixed block 413 is located on both sides of the loosening vehicle body 1. The hydraulic telescopic rod extends and retracts, pushing the movable sleeve 4111 to further fine-tune the soil penetration depth of the plowing blade 416.

[0043] Step 4: The operator holds the push handle and pushes the loosening vehicle 1 forward. The moving roller 313 rolls on the ground, and the grooves on its outer wall increase friction to ensure the vehicle moves forward stably. The plowing blades 416 first cut into the soil to loosen and break up the deep soil. Depending on the previously adjusted depth, the operation is carried out in soil layers at different depths.

[0044] Step 5: After the work is completed, push the loosening vehicle 1 to the designated location and park it. Clean the soil and debris attached to the plow blades 416 and the turning wheel 319, and check whether any parts are damaged or loose.

[0045] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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 this utility model should be included within the protection scope of this utility model.
