Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and in particular to a simple sweet potato harvesting plow. Background Technology

[0002] Sweet potatoes are an important food and cash crop, widely cultivated. Harvesting is the most labor-intensive and time-consuming part of sweet potato production. Traditionally, sweet potato harvesting relied mainly on manual digging or simple animal-powered plows, which were not only inefficient but also prone to damaging the tubers. With the development of agricultural mechanization, various types of sweet potato harvesters have emerged, among which the digging plow is widely used due to its simple structure and low cost.

[0003] However, existing simple sweet potato harvesting plows still have significant limitations in actual operation. Most harvesting plows use a fixed digging shovel or plow body structure, whose entry angle and depth are set at the factory, or can only be finely adjusted by cumbersome manual bolts. Faced with the differences in tuber formation depth among different sweet potato varieties and the variations in soil compaction in different plots, this fixed structure often makes it difficult to maintain the optimal digging posture, easily leading to missed digging or damage to tubers.

[0004] More importantly, traditional simple harvesting plows mainly rely on the passive lifting of the digging components to separate sweet potatoes from the soil, lacking an active soil-breaking mechanism. In heavy clay soils or soils with high moisture content, the excavated clods are difficult to break up, causing sweet potatoes to often be encased in a large amount of mud and hard clods. This not only increases the difficulty of subsequent manual picking and cleaning, but also easily damages the sweet potato skin during the compression and rolling of the clods, affecting the commercial value and storage life of the sweet potatoes.

[0005] Therefore, this utility model proposes a simple sweet potato harvesting plow to address the shortcomings of existing technologies. Utility Model Content

[0006] In view of the problems existing in the sweet potato harvesting plow, such as difficulty in adjusting the digging posture, inability to adapt to different soil and variety requirements, poor separation of sweet potato and soil after digging, and easy damage to the fruit, this utility model aims to provide a simple sweet potato harvesting plow with an improved structure that can effectively solve the above problems.

[0007] This utility model provides a simple sweet potato harvesting plow, including: a plow head, a plow body, plow wings, a column, connecting parts and a plow frame; as well as a vibration mechanism installed on the plow frame and an adjustment mechanism installed on the column.

[0008] The plowshare is located at the lowest end of the device and is fixedly connected to the plow body. The plow wings are symmetrically assembled on both sides of the plow body. The upper end of the plow body is vertically connected to the column. The column is connected to the horizontally arranged plow frame through the connector. The vibration mechanism includes a support block one, a drive assembly, a spring, a limit rod, a limit plate, a limit box, a limit block, and an impact column. The adjustment mechanism includes a support block two, a motor two, a limiting rod, a limit arm one, a rotating ball, a transmission rod, a motor three, and a limit arm two.

[0009] Furthermore, the support block one in the vibration mechanism is fixed to the side of the plow frame, and the motor one in the drive assembly is inserted and fixed inside the limiting box, driving the guide block to reciprocate linearly along the guide rod, compressing the spring and pushing the impact column to continuously impact the plow frame; the adjustment mechanism is fixed to the column with the support block two as the base, and uses the motor two and the motor three to drive the rotating ball in the connecting piece to rotate at multiple angles through the limiting arm one, the limiting arm two and the transmission rod, thereby changing the tilt angle of the column.

[0010] Preferably, the drive assembly further includes a guide block, which is driven by the motor to reciprocate linearly along the guide rod. The spring is sleeved on the outside of the guide rod and is repeatedly compressed and released when the guide block moves, thereby efficiently converting the rotational power provided by the motor into elastic potential energy to provide explosive force for the impact action.

[0011] Preferably, the elastic force generated by the spring is transmitted to the limiting block through the spring, the limiting rod, and the limiting plate. Multiple limiting plates are fixed to the top of the limiting box. The limiting block is pushed by the force to move the impact column. This force transmission path design ensures the concentrated release of vibration energy and enhances the impact effect.

[0012] Preferably, the plow frame receives the impact of the impact column and transmits the high-frequency slight vibration to the lower column, the plow body, the plow head and the plow wings. By utilizing the conduction characteristics of the rigid connection structure, the entire digging component resonates, thereby effectively shaking off the soil adhering to the surface of the sweet potato.

[0013] Preferably, after the second motor is started, the power is transmitted to the first limiting arm through the limiting rod. The limiting rod is fixed inside the second support block and provides limiting support for the first and second limiting arms to prevent excessive displacement of the two arms during the adjustment process and to ensure the accuracy of the adjustment action.

[0014] Preferably, the motor three drives the second limiting arm to move synchronously with the first limiting arm. The first limiting arm and the second limiting arm drive the connecting piece to move through the transmission rod. This dual-arm coordinated drive provides greater adjustment torque, ensuring that posture adjustment can be successfully completed even under heavy load conditions.

[0015] Preferably, the movement of the connector drives the rotating ball to rotate at multiple angles. By adjusting the posture of the rotating ball, the tilt angle of the column is changed, thereby controlling the soil penetration depth of the plow head, the support angle of the plow body, and the opening range of the plow wings, thus achieving refined management of excavation operation parameters.

[0016] Preferably, the adjustment mechanism is fixed to the corresponding area of ​​the column by the second support block, and the first support block of the vibration mechanism is fixed to the side of the plow frame. The plow body is vertically connected to the column. This layout makes reasonable use of space, so that the vibration and adjustment functions do not interfere with each other, and ensures the compactness of the whole machine structure.

[0017] This utility model has the following beneficial effects:

[0018] 1. This utility model, by setting up a vibration mechanism, uses a motor to drive an eccentric or cam assembly to drive a guide block and spring to store and release energy, pushing the impact column to intermittently impact the plow frame, generating high-frequency vibration and transmitting it to the digging component. This solves the problem of large amount of soil on the surface of sweet potato tubers after digging and the difficulty of manual cleaning in existing sweet potato harvesting equipment. It achieves the technical effect of quickly separating sweet potato tubers from adhering soil and hard soil clods, reducing the impurity rate after harvesting, and reducing mechanical damage to the fruit caused by the compression of hard soil clods.

[0019] 2. This utility model, by setting an adjustment mechanism, utilizes the ball joint connection structure at the top of the column and the connecting rod assembly driven by dual motors to achieve flexible tilt adjustment of the column relative to the plow frame at multiple angles. This solves the problem that the traditional harvesting plow has a fixed angle and depth of soil entry, and cannot adapt to the planting depth of different sweet potato varieties and the difference in soil compaction in different plots. It achieves the technical effects of precisely controlling the plow head's soil entry posture, optimizing digging resistance, improving digging efficiency and adaptability.

[0020] 3. This utility model, by setting the sliding cooperation between the guide rod and the guide block and the limiting support of the limiting rod on the limiting arm, constructs a stable motion guiding system, which solves the problem that vibration and adjustment components are prone to swaying, jamming or motion failure under high load operating environment, and achieves the technical effect of improving the overall operating stability of the device and extending the service life of key moving parts.

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0029] Example:

[0030] Reference Figures 1 to 5 This utility model provides a simple sweet potato harvesting plow, which aims to solve the structural defects of existing sweet potato harvesting equipment that cannot flexibly adjust the soil entry posture according to soil compaction and variety, and that the separation effect of sweet potato tubers from soil after digging is poor and easily causes fruit damage.

[0031] The simple sweet potato harvesting plow includes a plow head 1, a plow body 2, plow wings 3, a column 4, a connector 5, and a plow frame 6, as well as a vibration mechanism 7 and an adjustment mechanism 8 integrated to achieve specific functions. The components work together to form an organic whole for sweet potato digging and separation.

[0032] The plow head 1, as the core soil-breaking component, is located at the bottom of the device. Its back is fixedly connected to the bottom of the plow body 2 by welding or bolting. It is used to cut into the soil layer first. The plow wings 3 are symmetrically assembled on both sides of the plow body 2. The plow wings 3 extend backward and upward to flip and guide the soil and sweet potato mixture dug up by the plow head 1 to both sides to prevent soil accumulation.

[0033] The upper end of the plow body 2 is vertically fixed to the bottom end of the column 4. The column 4 is a key support member connecting the underground excavation component and the ground traction component. It has sufficient structural strength to withstand the excavation resistance. The top of the column 4 is connected to the horizontally arranged plow frame 6 through the connector 5. The connector 5 is not a simple rigid fixation, but allows the relative posture adjustment between the column 4 and the plow frame 6 through a specific matching relationship. The plow frame 6 serves as the installation skeleton of the entire device. Its front end is used to connect to the traction power such as tractors, and its rear end and sides are used to support auxiliary mechanisms.

[0034] The vibration mechanism 7 is installed on the crossbeam section of the plow frame 6. It generates high-frequency vibration through a specific mechanical structure and transmits it to the plow frame 6, which in turn transmits it to the plow head 1 and plow wings 3 below to achieve soil separation. The adjustment mechanism 8 is set in the column 4. It works closely with the column 4 and the connecting parts 5. It changes the tilt angle of the column 4 relative to the plow frame 6 through the action of the internal drive element, thereby achieving precise control of the depth of the plow head 1 into the soil.

[0035] The support block 71 of the vibration mechanism 7 is fixed to the side of the plow frame 6, providing a stable mounting point for the vibration component. The adjustment mechanism 8 is fixed to the corresponding area of ​​the column 4 with the support block 81 as the mounting base, ensuring the stability of the fulcrum for the adjustment action. With this layout, the harvesting plow can complete multiple tasks such as digging, breaking up soil, separating and adjusting posture simultaneously during the movement.

[0036] The vibration mechanism 7 is mainly composed of a support block 71, a drive assembly 72, a spring 73, and an impact actuator. The support block 71 serves as the main mounting body for the vibration unit and is installed on the side crossbeam of the plow frame 6 by bolts or welding. The limit box 76 is arranged horizontally and its two ends are fixedly connected to the internal space of the support block 71. Several limit plates 75 are also fixedly connected to the top of the limit box 76 to limit the stroke of the internal moving parts and provide guidance assistance.

[0037] A drive assembly 72 is installed in the internal cavity of the limiting box 76. The drive assembly 72 includes a motor 721, a guide block 722, and a guide rod 723. The motor 721 passes through and is fixedly connected to the inner wall of the limiting box 76, serving as a power source to provide initial mechanical energy. One end of the guide rod 723 is fixedly connected to the inside of the limiting block 77. The guide block 722 is slidably connected to the outer cylindrical surface of the guide rod 723 through its central through hole. The output shaft of the motor 721 and the guide block 722 are connected by a conventional transmission mechanism such as an eccentric wheel or a cam, thereby converting the rotational motion of the motor 721 into the reciprocating linear motion of the guide block 722 along the axial direction of the guide rod 723.

[0038] Spring 73 is sleeved on the outside of guide rod 723 and located between guide block 722 and limit rod 74. During the reciprocating sliding of guide block 722, spring 73 is repeatedly compressed and released, generating periodic elastic force. One end of limit rod 74 abuts against spring 73, and the other end passes through limit plate 75 and limit block 77 in sequence and is finally fixedly connected. Impact column 78 is fixedly connected to the bottom of limit block 77 and is perpendicular to the outer wall of plow frame 6. Under the combined action of spring 73 elastic force and motor driving force, limit block 77 drives impact column 78 to perform high-frequency reciprocating motion and continuously and intermittently impact plow frame 6. The vibration wave generated by this impact is transmitted downward along the rigid connection structure to plow head 1 and plow wings 3, causing the soil surrounding sweet potato to loosen and fall off.

[0039] Support block 2 81 is fixedly connected to the outer wall of column 4 by welding or bolt fastening as the installation carrier. Motor 2 82 and Motor 3 87 are fixedly installed side by side in the internal cavity of support block 2 81. The top of the limiting rod 83 is fixedly connected to the inner top wall of support block 2 81 and extends vertically downward. The output shaft of motor 2 82 passes through the motor housing and is fixedly connected to one end of limiting arm 1 84. The output shaft of motor 3 87 is fixedly connected to one end of limiting arm 2 88. The limiting rod 83 is located between limiting arm 1 84 and limiting arm 2 88. The outer surface of the limiting rod 83 is in contact or has a slight clearance fit with the side of limiting arm 1 84 and limiting arm 2 88 to prevent excessive swing of the limiting arm during movement.

[0040] One end of the transmission rod 86 is hinged to the end of the first limiting arm 84 and the second limiting arm 88 away from the motor via a pin. The other end of the transmission rod 86 extends to the top of the column 4 and is fixedly connected thereto. The connecting piece 5 is fixedly installed at the bottom of the plow frame 6. The connecting piece 5 has a spherical cavity for accommodating the rotating ball 85. The rotating ball 85 is rotatably embedded in the spherical cavity. The top of the column 4 passes through the opening at the bottom of the connecting piece 5 and is inserted into the spherical cavity and fixedly connected to the rotating ball 85. The size of the opening at the bottom of the connecting piece 5 is larger than the diameter of the column 4 to reserve space for tilting and swinging. The structure uses the rotating ball 85 to build a flexible connection fulcrum between the column 4 and the plow frame 6. With the pushing and pulling action of the transmission rod 86, the angle between the axis of the column 4 and the vertical line of the ground can be changed, thereby synchronously adjusting the working posture of the plow head 1 and the plow body 2.

[0041] The implementation principle of this application embodiment is as follows: the plow head 1 is located at the bottom of the device and is fixedly connected to the plow body 2. The plow wings 3 are symmetrically assembled on both sides of the plow body 2. The upper end of the plow body 2 is vertically connected to the column 4. The column 4 is connected to the horizontally arranged plow frame 6 through the connector 5. The vibration mechanism 7 is installed on the crossbeam section of the plow frame 6. Its support block 1 71 is fixed to the side of the plow frame 6. The adjustment mechanism 8 is set in the column 4. Its support block 2 81 is fixed in the corresponding area of ​​the column 4.

[0042] The adjustment mechanism 8 is fixed to the column 4 with the support block 2 81 as the mounting base. After the motor 2 82 is started, the power is transmitted to the limiting arm 1 84 through the limiting rod 83. The top of the limiting rod 83 and the motor 2 82 are fixed inside the support block 2 81. At the same time, the motor 3 87 drives the limiting arm 2 88 to move synchronously. The motor 3 87 is fixed inside the support block 2 81. The limiting rod 83 provides limiting support for the limiting arm 1 84 and the limiting arm 2 88. The two drive the core connecting piece 5 to move through the transmission rod 86. The rotating ball 85 rotates at multiple angles. The transmission rod 86 is fixedly connected to one end of the column 4. By adjusting the posture of the rotating ball 85, the tilt angle of the column 4 can be changed, thereby precisely controlling the soil penetration depth of the plow head 1, the support angle of the plow body 2, and the opening range of the plow wings 3, adapting to the planting depth and soil compaction of different sweet potato varieties.

[0043] The support block 71 of the vibration mechanism 7 is fixed to the crossbeam of the plow frame 6. After the motor 721 in the drive assembly 72 is started, the motor 721 passes through and is fixed inside the limit box 76, driving the guide block 722 to reciprocate linearly along the guide rod 723. The guide rod 723 is fixed inside the limit block 77. At this time, the spring 73 sleeved on the outside of the guide rod 723 will be repeatedly compressed and released. The elastic force is transmitted to the limit block 77 through the spring 73, the limit rod 74, and the limit plate 75. Multiple limit plates 75 are fixed at the top of the limit box 76. The two ends of the limit box 76 are fixed inside the support block 71, which finally pushes the impact column 78 to continuously impact the plow frame 6. The plow frame 6 transmits high-frequency slight vibrations to the lower column 4, plow body 2, plow head 1, and plow wings 3, so that the soil and sweet potato are quickly separated, which reduces the amount of soil on the surface of the sweet potato and avoids the hard soil clods squeezing the sweet potato and causing damage.

[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present 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.
