DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] To make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be described in detail below. Apparently, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other implementation manners obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope protected by the present invention.

[0022] As shown in Figures 1-6 , the present invention provides an integrated device for loosening soil and punching holes for vegetable planting, which includes a roller 1 and a digital display control panel. An outer support structure 2 for supporting the rotation of the roller 1 is arranged on the outer side of the roller 1, and a rotary drive assembly 5 for driving the roller 1 to rotate is arranged on the outer support structure 2; a telescopic chute 101 penetrating through its axis is formed on the roller 1, and a plurality of punching cylinders 8 evenly distributed are arranged in the telescopic chute 101. A linear drive assembly for driving the punching cylinders 8 to telescopically move out of the telescopic chute 101 respectively is arranged on the roller 1; an inner soil pushing structure 9 is arranged in the telescopic chute 101. During the process of the linear drive assembly driving the punching cylinders 8 to move, the inner soil pushing structure 9 can push out the soil column in the punching cylinders 8; a soil loosening knife 4 for loosening the soil between two adjacent cylinders 8 during the rotation of the roller 1 is arranged on the outer side of the roller 1, and a vibration structure 7 is arranged on the soil loosening knife 4. When the roller 1 moves horizontally, it drives components such as the soil loosening knife 4 and the punching cylinders 8 to move, realizing the operations of soil loosening and punching.

[0023] See the attached drawings of the specification Figure 3 , the edges of both ends of the punching cylinder 8 are in the shape of a blade. The blade shape can effectively reduce the resistance when the punching cylinder 8 is inserted into the soil, making it easier to cut into the soil and reducing power consumption; at the same time, the sharp blade can make the edges of the planted holes punched relatively regular, avoiding excessive disturbance to the soil, being beneficial to subsequent vegetable planting and root growth. The axis of the punching cylinder 8 is consistent with the radial direction of the roller 1, ensuring that when the punching cylinder 8 rotates with the roller 1, it can be inserted into the soil perpendicular to the ground, making the punched planting holes in a vertical state, meeting the requirements of vegetable planting for the direction of the planting holes, facilitating the accurate placement of subsequent seedlings or seeds, and being beneficial to the vertical downward growth of the roots. And the axial length of the punching cylinder 8 is consistent with the radial length of the roller 1.

[0024] See the attached drawings of the specification Figure 2 and Figure 4As shown in the figure, telescopic sliding frames 801 capable of sliding within telescopic sliding grooves 101 are connected between the punching and inserting cylinders 8. Installation chambers 104 are provided at both axial ends of the roller 1. Fixed blocks 10 are fixedly arranged within the installation chambers 104. Electric telescopic rods 11 are fixedly arranged on the fixed blocks 10. The push rod head end of the electric telescopic rod 11 is connected to the telescopic sliding frame 801. The telescopic direction of the push rod of the electric telescopic rod 11 is consistent with the sliding direction of the telescopic sliding frame 801 within the telescopic sliding groove 101. The output end of the digital display control panel is electrically connected to the input end of the electric telescopic rod 11. During vegetable planting operations, the electric telescopic rod 11 is controlled through the digital display control panel. The electric telescopic rod 11 drives the telescopic sliding frame 801 to drive the punching and inserting cylinders 8 to extend out of the roller 1, and planting holes with controllable depths are punched in the soil using the cutting edges of the punching and inserting cylinders 8. After the operation is completed, the punching and inserting cylinders 8 can be controlled to retract into the roller 1. The coordinated operation of the entire system not only improves the punching efficiency but also can flexibly adjust the punching depth according to different planting requirements, providing strong support for vegetable planting and enhancing the quality and effect of the planting operation.

[0025] See the attached instructions Figure 4 and Figure 5 As shown in the figure, the internal soil pushing structure 9 includes internal guiding sliding grooves 802 opened within the telescopic sliding frame 801. An internal pushing column 901 is arranged within each punching and inserting cylinder 8 for pushing the soil column out of the punching and inserting cylinder 8 to prevent the soil column from remaining and affecting subsequent punching operations, ensuring the continuity and high efficiency of punching. Side opening sliding grooves 803 are opened on both side walls of each punching and inserting cylinder 8. Connecting rods 902 are connected between the internal pushing columns 901. The connecting rods 902 are slidably connected in cooperation with the side opening sliding grooves 803. An effective relative displacement can be generated between the punching and inserting cylinder 8 and the internal pushing column 901 to complete the soil pushing action. Both ends of the connecting rod 902 are fixedly connected to the two fixed blocks 10 respectively, where the fixed block 10 provides a fixed support point for the connecting rod 902. The axial length of the internal pushing column 901 is less than the axial length of the punching and inserting cylinder 8. The various components of the internal soil pushing structure 9 cooperate with each other to jointly realize the function of automatically pushing out the soil column during the process of the punching and inserting cylinder 8 retracting after punching. When the punching and inserting cylinder 8 retracts into the roller 1 driven by the electric telescopic rod 11, the punching and inserting cylinder 8 moves relative to the fixed connecting rod 902 and internal pushing column 901. Driven by the connecting rod 902, the internal pushing column 901 pushes out the soil column within the punching and inserting cylinder 8 along the guidance of the internal guiding sliding groove 802 through the side opening sliding groove 803. This structural design effectively solves the problem of soil column residue during punching, ensures the continuous progress of the punching operation, improves the working efficiency and practicality of the soil loosening and punching integrated device for vegetable planting, and provides reliable technical support for the punching link of vegetable planting. See the attached instructions Figure 1 and Figure 2As shown in the figure, more than two outer opening grooves 102 are formed on the outer side of the roller 1, and the soil loosening knives 4 are arranged in the outer opening grooves 102. During the soil loosening operation, the rotation of the roller 1 provides the driving force for the soil loosening knives 4, enabling the soil loosening knives 4 to continuously act on the soil. The soil loosening knives 4 located in the same outer opening groove 102 are connected to each other by a tool rest 401. The tool rest 401 is fixedly arranged on the inner side wall of the outer opening groove 102 by bolts. A tip is formed on the side of the soil loosening knife 4 opposite to the tool rest 401, and the tip protrudes from the outer surface of the roller 1. When the roller 1 rotates, the tips of the soil loosening knives 4 cut into the soil, and by continuously turning and crushing the soil, the soil becomes loose, creating suitable soil conditions for vegetable planting. Multiple soil loosening knives 4 are distributed in different outer opening grooves 102, enabling the soil loosening operation on a larger area of soil during one rotation of the roller 1, thereby improving the soil loosening efficiency.

[0026] See the attached drawings in the specification Figure 3 As shown in the figure, the vibration structure 7 includes a linkage rod 702 for connecting each soil loosening knife 4 located in the same outer opening groove 102. Its function is to connect each soil loosening knife 4 located in the same outer opening groove 102 into a whole. In this way, when the vibration motor 701 generates vibration, the linkage rod 702 can evenly and efficiently transmit the vibration to each soil loosening knife 4 connected thereto, ensuring that multiple soil loosening knives 4 vibrate synchronously, enhancing the overall vibration effect, and improving the soil crushing and loosening ability. Through the connection of the linkage rod 702, the originally independently working soil loosening knives 4 achieve collaborative operation in terms of vibration, improving the consistency and efficiency of the soil loosening operation. Vibration motors 701 are arranged at both ends of the linkage rod 702. Embedding holes 103 for embedding the vibration motors 701 are formed at both ends of the roller 1. Soft guards 703 are arranged at the ports of the embedding holes 103 facing the outer opening grooves 102, playing a protective role to prevent soil particles, sundries, etc. from entering the interior of the embedding holes 103 during the soil loosening operation and damaging the vibration motors 701. The output end of the digital display control panel is electrically connected to the input end of the vibration motor 701.

[0027] See the attached drawings in the specification Figure 2 、 Figure 3 and Figure 6As shown, the outer support structure 2 includes a horizontal support 201 and a vertical support 202 that are connected to each other. There are more than two connecting frames 203 connecting the horizontal support 201 and the vertical support 202 to each other. A detection ground wheel structure 6 for performing ground contact detection is provided on the horizontal support 201. A lifting drive assembly 3 for driving its up and down movement is provided on the outer support structure 2. An angle sensor 12 for detecting the rotation angle of the roller 1 is provided on the outer support structure 2. The angle sensor 12 monitors and feeds back the rotation angle of the roller 1, thereby providing detection feedback for the drilling operation of the drilling and inserting cylinder 8. Thus, when the axis of the drilling and inserting cylinder 8 is perpendicular to the ground, the soil drilling operation is completed, ensuring that the rotation of the roller 1 meets the operation requirements.

[0028] See the attached instructions Figure 2 and Figure 3 As shown, the rotary drive assembly 5 includes a motor 504 fixedly arranged on the vertical support 202. A first toothed belt pulley 501 is connected to the output shaft end of the motor 504. A second toothed belt pulley 503 is connected to the shaft end of the roller 1. A toothed belt 502 is meshingly connected between the first toothed belt pulley 501 and the second toothed belt pulley 503. The motor 504 is fixedly arranged on the vertical support 202 through a machine base 505. The output end of the digital display control panel is electrically connected to the input end of the motor 504. Each component of the rotary drive assembly 5 closely cooperates to jointly realize the function of providing stable and controllable rotary power for the roller 1. The motor 504 outputs power under the control of the digital display control panel. Through the transmission system composed of the first toothed belt pulley 501, the toothed belt 502 and the second toothed belt pulley 503, the power is efficiently and accurately transmitted to the roller 1, driving the roller 1 to rotate at a set speed and direction. The machine base 505 ensures the stability of the installation of the motor 504. The entire rotary drive assembly 5 works in coordination with other parts of the device such as the outer support structure 2, the soil loosening knife 4, and the drilling and inserting cylinder 8, ensuring that the integrated soil loosening and drilling device for vegetable planting can smoothly perform soil loosening and drilling operations, meeting various requirements for the rotary movement of the roller in the soil treatment work before vegetable planting, and improving the working efficiency and operation quality of the device.

[0029] The detection ground wheel structure 6 includes a wheel rod 601. One end of the wheel rod 601 is rotatably provided with a ground wheel 603. A guard plate 604 for protecting the top side of the ground wheel 603 is arranged on the wheel rod 601. The other end of the wheel rod 601 is hinged to the horizontal support 201 through a hinge seat 602. A torsion spring is arranged at the connection between the hinge seat 602 and the wheel rod 601. A support shaft 605 is connected to the upper side of the hinge seat 602. A pressure sensor 606 is arranged between the support shaft 605 and the horizontal support 201. The output end of the pressure sensor 606 is electrically connected to the input end of the digital display control panel. Each component of the detection ground wheel structure 6 cooperates with each other to jointly realize the function of real-time detection and feedback of the ground condition. During the operation of the integrated device for loosening soil and punching holes in vegetable planting, the ground wheel 603 contacts and rolls on the ground, senses the change of the ground condition. The wheel rod 601 transmits the force received by the ground wheel 603 to the pressure sensor 606. The pressure sensor 606 converts the pressure change into an electrical signal and transmits it to the digital display control panel. The operator understands the ground situation according to these signals and adjusts the working parameters of the device accordingly. The guard plate 604 protects the normal operation of the ground wheel 603, and the hinge seat 602 and the support shaft 605 ensure the transmission of force and the stability of the structure. The entire detection ground wheel structure 6 provides ground condition information for the device, helps to improve the accuracy and efficiency of the device in loosening soil and punching holes under different ground conditions, provides strong support for the soil treatment work before vegetable planting, and improves the intelligent and adaptable level of the device.

[0030] The lifting drive assembly 3 includes a mounting seat plate 301. A plurality of mounting holes 304 are formed on the mounting seat plate 301. Two or more hydraulic cylinders 302 are fixedly arranged on the mounting seat plate 301. The push rod head ends of the hydraulic cylinders 302 are fixedly connected to the horizontal support 201. Two or more parallel distribution guide rods 303 are fixedly connected to the vertical support 202. A guide sliding hole for cooperating with the guide rods 303 to slide is formed on the mounting seat plate 301. The output end of the digital display control panel is electrically connected to the input end of the hydraulic cylinder 302. During the operation of the device, the operator controls the work of the hydraulic cylinder 302 through the digital display control panel. The telescopic movement of the push rod of the hydraulic cylinder 302 drives the horizontal support 201 and the whole device to move up and down. The mounting seat plate 301 provides mounting support for the hydraulic cylinder 302, and through the cooperation of the guide sliding hole and the guide rods 303, it ensures the smoothness and accuracy of the lifting movement of the device. The mounting holes 304 are used to connect the lifting drive assembly 3 with external equipment. The entire lifting drive assembly 3 cooperates with other parts of the device, and according to the ground condition feedback by the detection ground wheel structure 6 and different planting requirements, flexibly adjusts the height of the device to ensure that the soil loosening knife 4 and the punching cylinder 8 can operate at an appropriate depth, improves the working efficiency and operation quality of the device, provides a reliable height adjustment guarantee for the soil treatment work before vegetable planting, and improves the practical and intelligent level of the device. The working principle and technical effect of the present invention: Instructions are issued through the digital display control panel to control the start of the motor 504. As the power source, the output shaft end of the motor 504 drives the first toothed belt pulley 501 to rotate. Since the first toothed belt pulley 501 and the second toothed belt pulley 503 are meshed and connected by the toothed belt 502, the rotation of the first toothed belt pulley 501 drives the movement of the toothed belt 502, which in turn causes the second toothed belt pulley 503 connected to the shaft end of the roller 1 to rotate, ultimately enabling the roller 1 to rotate under the support of the outer support structure 2. The rotation of the roller 1 is the basic movement for subsequent operations such as soil loosening and hole punching in the entire device.

[0031] When the roller 1 starts to rotate, the soil loosening knives 4 installed in the outer opening groove 102 will rotate together with the roller 1. During the rotation, the soil loosening knives 4 come into contact with the soil. The design that their tips protrude from the outer surface of the roller 1 enables the soil loosening knives 4 to cut into the soil, turning and breaking the soil between two adjacent punching cylinders 8, achieving the purpose of soil loosening. At the same time, the vibration motor 701 starts to work under the control of the digital display control panel. The vibration motor 701 transmits the vibration to each soil loosening knife 4 located in the same outer opening groove 102 through the linkage rod 702, causing the soil loosening knives 4 to generate high-frequency vibrations. This vibration can further enhance the soil loosening effect. Especially for some relatively compact soils, the vibration helps the soil loosening knives 4 to more easily cut into the soil and break the soil clods, making the soil more loose, which is beneficial to the growth and extension of the roots during subsequent vegetable planting. Also, the soft shields 703 provided at the insertion holes 103 at both ends of the roller 1 can prevent dirt and other sundries from entering the insertion holes 103 to a certain extent, affecting the normal operation of the vibration motor 701.

[0032] When the digital display control panel controls the push rod of the electric telescopic rod 11 to extend, it will push the telescopic carriage 801 to move in one direction along the telescopic chute 101; when the push rod retracts, the telescopic carriage 801 moves in the other direction along the telescopic chute 101, thereby enabling the punching cylinders 8 to extend and retract from both ends of the telescopic chute 101 respectively.

[0033] Since the edges of both ends of the punching cylinder 8 are in the shape of a blade, and its axial direction is consistent with the radial direction of the roller 1, and its length is also consistent with the radial length of the roller 1, it can smoothly insert into the soil for hole punching operations. By controlling the telescopic amount of the electric telescopic rod 11, the depth of the punching cylinder 8 inserted into the soil can be accurately controlled to meet the requirements for the depth of planting holes in different vegetable plantings.

[0034] During the telescopic movement of the punching and inserting cylinder 8, the inner soil pushing structure 9 comes into play. Since both ends of the connecting rod 902 are fixedly connected to two fixed blocks 10 respectively, and the inner pushing column 901 is connected together through the connecting rod 902, and the connecting rod 902 is slidably connected with the side opening chute 803 on the side wall of the punching and inserting cylinder 8. When the punching and inserting cylinder 8 extends outwards and inserts into the soil and then retracts, the punching and inserting cylinder 8 generates relative movement with respect to the fixed connecting rod 902 and the inner pushing column 901, causing the inner pushing column 901 to slide in the side opening chute 803, thereby pushing out the soil column brought out of the punching and inserting cylinder 8, preventing the soil column from remaining in the punching and inserting cylinder 8 and affecting the next punching operation, and ensuring the continuity and efficiency of punching.

[0035] The ground wheel 603 in the ground wheel structure 6 is in contact with the ground. When the ground conditions change, such as when the ground has undulations or different soil hardness, the ground wheel 603 will be subjected to different degrees of force. This force will cause the wheel rod 601 to rotate around the hinge seat 602, and the torsion spring provided at the connection between the hinge seat 602 and the wheel rod 601 will undergo corresponding deformation. At the same time, the rotation of the wheel rod 601 will cause the support shaft 605 to generate a pressure change on the pressure sensor 606. The pressure sensor 606 converts the detected pressure change signal into an electrical signal and transmits it to the digital display control panel. The digital display control panel can judge the ground conditions according to the received signal, such as the compactness of the soil, the flatness of the ground, etc., and then provide a reference for the operator so as to adjust the working parameters of the device, such as the lifting height, the loosening intensity, etc., according to the actual situation.

[0036] The mounting seat plate 301 is fixedly installed with the external vehicle body through the mounting holes 304. The telescopic movement of the push rod of the hydraulic cylinder 302 can drive the outer support structure 2 to move up and down. The guide rod 303 fixedly connected to the vertical support 202 plays a role in guiding and stabilizing, ensuring the smoothness of the device during the lifting process and preventing shaking or deviation. This lifting adjustment function can adjust the relative height between the device and the ground according to different soil conditions and planting requirements.

[0037] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
