Description

Technical Field

[0001] This utility model relates to the field of soil deep tillage machine technology, specifically to a deep tillage machine for improving soil in vegetable planting. Background Technology

[0002] In vegetable cultivation, high-quality soil conditions are fundamental to ensuring healthy growth and improving yield and quality. However, with the large-scale and intensive development of modern agriculture, soil problems in vegetable-growing areas are becoming increasingly prominent. On the one hand, long-term monoculture planting methods and the excessive use of chemical fertilizers have led to severe soil compaction, reduced soil aeration and water permeability, making it difficult for vegetable roots to breathe and grow normally, thus affecting nutrient absorption. On the other hand, soil fertility is imbalanced, organic matter content is declining, and the number of beneficial microorganisms is decreasing, exacerbating the occurrence of soil-borne diseases and reducing the disease resistance and quality of vegetables. In addition, some areas also suffer from soil pH imbalances, further limiting vegetable growth.

[0003] To achieve soil loosening, a soil improvement subsoiler is typically used. Patent CN104472032A discloses a vibratory subsoiler, characterized by: a frame, traction device, transmission device, vibratory subsoiler, and depth control device. The traction device is located at the front of the frame. The transmission device consists of a power input shaft, a drive shaft, a drive sprocket, a crankshaft, a driven sprocket, a drive connecting rod, and a driven connecting rod. The power input shaft is located at the front of the frame, the drive shaft at the lower part of the frame, the drive sprocket on the drive shaft, the crankshaft in the upper middle part of the frame, the driven sprocket and drive connecting rod on the crankshaft, and the driven connecting rod on the drive connecting rod. The vibratory subsoiler is located at the rear of the frame, and the depth control device is located on both sides of the frame. This invention effectively reduces the traction resistance of the vibratory subsoiler, resulting in good soil loosening. It also prevents tractor vibration caused by the vibration of the vibratory subsoiler, thus avoiding discomfort for the tractor driver.

[0004] While this technical solution offers advantages such as good soil loosening, most current soil improvement and deep tillage machines still have some shortcomings in use. For example, most machines use deep tillage shovels inserted into the soil at constant intervals, and then the machine moves to move the shovels through the soil to turn it over and achieve deep loosening. However, during the soil turning process, many large clumps of soil become clumped together, making it impossible to further break up the clumps and affecting the loosening effect. Therefore, we propose a soil improvement and deep tillage machine for vegetable cultivation. Utility Model Content

[0005] The purpose of this invention is to provide a deep tillage machine for vegetable planting soil improvement, so as to solve the defects mentioned in the background art.

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

[0007] A soil improvement and deep tillage machine for vegetable cultivation includes a hydraulic arm mounted on the soil deep tillage machine. Two sets of vertical beams are fixedly installed at the bottom of the hydraulic arm, with multiple beams in each set arranged at equal intervals along the longitudinal direction. An adjustable-angle deep tillage shovel is installed at the bottom of each vertical beam, and the shovel is inserted into the soil for loosening operations. A vertically oriented column is also fixedly installed at the bottom of the hydraulic arm, and an arc-shaped cover is fixedly installed at the bottom of the column. Side plates are fixedly installed at both the front and rear ends of the arc-shaped cover. A central rotating shaft is rotatably connected between the two side plates. A blade assembly roller is fixedly installed on the central rotating shaft, and multiple sets of crushing blades are fixedly installed on the blade assembly roller. The central rotating shaft is driven by a motor.

[0008] Preferably, the two sets of vertical beams are arranged in an alternating pattern, and the multiple crushing blades in each set are arranged in a ring at equal intervals.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This utility model achieves flexible and precise soil loosening operations by setting two sets of staggered vertical beams with equal longitudinal spacing at the bottom of the hydraulic arm, and installing an adjustable deep loosening shovel at the bottom of the beams. The deep loosening shovel at different angles can adapt to different soil types and planting needs, effectively break up the soil compaction layer, improve soil aeration and water permeability, and create good conditions for vegetable root growth.

[0019] 2. This utility model achieves efficient crushing of large consolidated soil clods generated during deep loosening by installing a vertical column at the bottom of the hydraulic arm and setting an arc-shaped cover with crushing teeth at its bottom end. At the same time, a blade assembly roller with crushing blades driven by a motor is set inside the arc-shaped cover, and the crushing blades are positioned between adjacent crushing teeth. The crushing teeth and crushing blades work together to crush the soil clods multiple times, ensuring that the soil is loose and uniform, and improving the soil improvement effect.

[0020] 3. This utility model achieves convenient adjustment and stable fixation of the deep loosening shovel angle by setting a hinged seat at the bottom of the vertical beam, setting a vertical rod rotatably connected to the hinged seat on the deep loosening shovel, and using an arc-shaped steel plate, fastening bolts and nuts to fix the angle of the deep loosening shovel. Operators can quickly adjust the angle of the deep loosening shovel according to actual operation needs to meet diverse soil improvement and deep loosening requirements, while ensuring that the deep loosening shovel will not deviate in angle during operation, thus improving the practicality and stability of the equipment.

[0027] 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.

[0028] Please see Figures 1-3 This utility model provides a technical solution: a deep tillage machine for vegetable planting soil improvement, including a hydraulic arm 1 installed on the deep tillage machine. The hydraulic arm 1 is driven by a hydraulic cylinder installed on the deep tillage machine. Two sets of vertical beams 10 are fixedly installed at the bottom of the hydraulic arm 1. Multiple vertical beams 10 in each set are arranged at equal intervals along the longitudinal direction. An adjustable-angle deep tillage shovel 14 is provided at the bottom end of the vertical beam 10. The deep tillage shovel 14 is inserted into the soil for soil loosening. The two sets of vertical beams 10 are arranged in an alternating manner, so that multiple deep tillage shovels 14 work together to loosen the soil over a large area and evenly. The equally spaced vertical beams 10 ensure the regularity of the deep tillage operation, avoid missed loosening or repeated deep tillage, and effectively improve the deep tillage efficiency.

[0029] In this embodiment, a vertical column 2 is fixedly installed at the bottom of the hydraulic arm 1. An arc-shaped cover 20 is fixedly installed at the bottom end of the vertical column 2. Side plates 22 are fixedly installed at both the front and rear ends of the arc-shaped cover 20. A central rotating shaft 23 is rotatably connected between the two side plates 22. A blade assembly roller 24 is fixedly installed on the central rotating shaft 23. Multiple sets of crushing blades 25 are fixedly installed on the blade assembly roller 24. The central rotating shaft 23 is driven by a motor. The output shaft of the motor is fixedly connected to the central rotating shaft 23 through a coupling. The motor is fixedly installed on the subsoiler. The multiple crushing blades 25 in each set are arranged in a ring with equal spacing. After the subsoiler shovel 14 loosens the soil, the crushing blades 25 can further contact the turned-up soil. The ring-shaped crushing blades 25 can crush the turned-up soil clods. The combination of the two makes the loosening and crushing of soil clods more thorough.

[0030] like Figure 1 and Figure 2As shown, multiple sets of crushing teeth 21 are fixedly installed on the inner wall of the arc-shaped cover 20 from front to back. Each set of crushing teeth 21 is arranged along the arc direction of the arc-shaped cover 20. Each set of crushing blades 25 is located between two adjacent sets of crushing teeth 21. When the central rotating shaft 23 drives the blade assembly roller 24 and the crushing blades 25 to rotate, the crushing blades 25 and the crushing teeth 21 form an interlaced crushing space. When the soil passes through this space, it will be cut by the crushing blades 25 and impacted by the crushing teeth 21. After multiple compressions and crushing, the crushing effect on the consolidated soil blocks is ensured, and the soil particles are further refined.

[0031] Specifically, the subsoil shovel 14 is set at a downward angle, and the crushing blade 25 is located behind the subsoil shovel 14, which conforms to the operation logic of deep loosening and crushing soil. The downward-sloping subsoil shovel 14 can more easily insert into the soil and turn it over. The turned-over soil then moves backward to the crushing blade 25, which promptly crushes the soil, making the entire operation process smooth and efficient.

[0032] like Figure 3 As shown, a hinge seat 11 is fixedly installed at the bottom end of the vertical beam 10, and a vertical rod 13 is fixedly installed on the rear side of the deep loosening shovel 14. The top end of the vertical rod 13 is located inside the hinge seat 11 and is rotatably connected to the left and right side plates of the hinge seat 11 via a rotating shaft. Arc-shaped steel plates 15 are fixedly installed on both the left and right sides of the vertical rod 13. The two arc-shaped steel plates 15 are fitted onto the left and right sides of the vertical beam 10, and the arc-shaped steel plates 15 are fixed to the vertical beam 10 by fastening bolts 16 and nuts 17. Multiple second bolt holes 151 are provided on the arc-shaped steel plates 15, and first bolt holes 12 are provided at corresponding positions on the vertical beam 10. The fastening bolts 16 pass through the first bolt holes 12 and the second bolt holes 151, and the nuts 17 are tightened on the fastening bolts 16. After the deep loosening shovel 14 is adjusted to a suitable angle, it can be firmly fixed. Multiple second bolt holes 151 on the arc-shaped steel plate 15 cooperate with the first bolt holes 12 on the vertical beam 10 to achieve multiple angle fixing options, ensuring that the deep loosening shovel 14 will not shift in angle due to soil resistance and other factors during operation, thus ensuring the stability and accuracy of deep loosening operations.

[0033] It is worth noting that the curved steel plate 15 and the pivot point on the vertical rod 13 are concentrically arranged. There are two first bolt holes 12 and eight to twelve second bolt holes 151. This arrangement ensures the flexibility of the submersible shovel 14 angle adjustment while enhancing the reliability of the fixing structure. The concentric arrangement makes the submersible shovel 14 rotate more smoothly, and the appropriate number of bolt holes not only meets the needs of different angle adjustments but also ensures the tightening force during fixing, making the entire angle adjustment and fixing system more scientific and practical.

[0034] When using the vegetable planting soil improvement and deep tillage machine of this utility model, first start the hydraulic cylinder installed on the improvement and deep tillage machine to drive the hydraulic arm 1 to adjust to a suitable working height and position. Then, adjust the deep tillage shovel 14 to a suitable angle and fix it according to the soil conditions and planting needs through the hinge seat 11, vertical rod 13, arc steel plate 15, fastening bolt 16 and nut 17.

[0035] Once ready, operate the subsoiler to move forward. The two sets of vertical beams 10 arranged in an alternating pattern on the left and right sides drive the subsoil shovels 14 to insert into the soil. The downward-sloping subsoil shovels 14 easily break through the compacted soil layer and turn the soil up. Multiple sets of subsoil shovels 14 work together to complete the soil loosening operation evenly and over a large area.

[0036] The turned-up soil can pass through the crushing blades 25. At this time, the motor is started to drive the central rotating shaft 23, so that the blade assembly roller 24 and the crushing blades 25 rotate at high speed. The crushing blades 25 arranged in a ring at equal intervals cooperate with the crushing teeth 21 set along the arc of the arc cover 20 to cut and impact the soil clods entering the arc cover 20. After multiple compression and crushing, the large soil clods are refined.

[0037] 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. The scope of protection of this utility model is defined by the appended claims and their equivalents.
