Description

Technical Field

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

[0002] Sweet potatoes, as an important food and feed crop, typically require crushing after harvesting to facilitate subsequent storage, fermentation, or further processing. A sweet potato crusher, as a key piece of equipment for achieving this purpose, has been widely used in agricultural production.

[0003] Existing sweet potato crushers primarily focus on optimizing the internal structure of the crushing chamber to improve crushing efficiency and effectiveness. However, in actual use, due to the significant differences in size and irregular shape of sweet potatoes, larger sweet potatoes, if directly fed into the crusher, can cause blockages at the feed inlet or become stuck between the crushing components. This leads to a sharp increase in equipment operating resistance and may even cause the motor to overload and shut down, severely impacting the continuity and stability of production.

[0004] To avoid the aforementioned problems, operators typically have to perform a manual pre-processing step before feeding the sweet potatoes into the crusher, which involves manually cutting large pieces of sweet potatoes into smaller chunks using blades. This manual pre-processing method not only significantly increases the labor intensity of the operators but also greatly reduces the automation level and overall efficiency of the entire crushing process, making the cutting stage a significant bottleneck in the entire production chain.

[0005] Therefore, this utility model proposes a sweet potato crusher to overcome the shortcomings of the existing technology. Utility Model Content

[0006] In view of the problems existing in the sweet potato crusher, such as the need for manual pre-cutting before crushing large pieces of material, low level of automation, high labor intensity and easy blockage, this utility model aims to provide a sweet potato crusher with an improved structure that can effectively solve the above problems.

[0007] This utility model provides a sweet potato crusher, including: a machine body, a hopper, a partition plate; and a cutting mechanism disposed between the hopper and the partition plate.

[0008] The cutting mechanism includes a support plate, a sliding rod is slidably connected inside the support plate, and a cutting blade is fixedly connected to the bottom end of the sliding rod.

[0009] The cutting mechanism also includes a drive assembly, which includes a servo motor fixed to one side of the support plate. The output end of the servo motor is rotatably connected to a cam. The profile surface of the cam abuts against the top of the slide rod, thereby driving the slide rod to drive the cutting blade to reciprocate, so as to realize automatic cutting before the material enters the machine body.

[0010] Preferably, the drive assembly further includes a spring, which is sleeved on the outer periphery of the slide rod. The two ends of the spring abut against the inner wall of the support plate and the flange fixed on the slide rod, respectively, to provide a restoring force to the slide rod after the cam thrust disappears.

[0011] Preferably, the drive assembly further includes a hollow elongated block, which is fixed to the support plate and houses the cam inside the hollow elongated block to protect the cam and prevent material debris from interfering with it.

[0012] Preferably, a sweet potato crusher further includes an energy-saving mechanism that is expandably connected to the outer wall of the machine body. The energy-saving mechanism includes an elongated frame plate, in which a solar panel is fixed. The energy-saving mechanism also includes a power component for driving the elongated frame plate to expand or retract.

[0013] Preferably, the power assembly includes a second servo motor, the output end of which is fixedly connected to a worm gear. The power assembly also includes a worm wheel meshing with the worm gear and a bidirectional threaded rod coaxially fixed on the worm wheel. The bidirectional threaded rod is threadedly engaged with the elongated frame plate, and the automatic deployment of the solar panel is achieved by motor drive.

[0014] Preferably, the power assembly also includes a hollow block, with the worm gear and the bidirectional threaded rod rotatably housed in the middle of the hollow block, and the servo motor fixed to the outside of the hollow block, forming a compact drive module.

[0015] Preferably, the power assembly also includes an elongated column, which is arranged parallel to the bidirectional threaded rod. The two ends of the elongated column are fixed to the hollow block, and the elongated column passes through the guide hole opened in the elongated frame plate to guide the movement of the elongated frame plate during the unfolding or retracting process and prevent it from rotating.

[0016] Preferably, the energy-saving mechanism includes two sets of elongated frame plates and solar panels symmetrically arranged on both sides of the body. Correspondingly, the bidirectional threaded rod has two sections of threads with opposite directions of rotation. The two sections of threads respectively engage with the threads of the elongated frame plates on both sides to achieve synchronous back-to-back expansion or front-to-back retraction of the elongated frame plates on both sides.

[0017] This utility model has the following beneficial effects: 1. This utility model solves the problem in the prior art that large materials such as sweet potatoes need to be pre-cut manually before crushing, which is inefficient and labor-intensive. It solves the problem by setting a cutting mechanism with servo motor, cam and slide bar working in coordination below the feed inlet of the crusher. It achieves the technical effect of automatically completing the cutting, improving the overall crushing efficiency and reducing labor costs.

[0018] 2. This utility model solves the problem of existing crushers relying too heavily on the power grid or generators, having high energy consumption and limited usage scenarios when operating outdoors, by setting up an energy-saving mechanism that uses a servo motor to drive a worm gear and a bidirectional threaded rod to control the unfolding and retraction of solar panels. It achieves the technical effects of using clean energy to provide auxiliary power to the equipment, reducing the energy consumption of the equipment, and enhancing the equipment's adaptability to the changing outdoor environment.

[0019] 3. This utility model, by modularly integrating the cutting mechanism and the energy-saving mechanism, and by adopting mature and reliable mechanical structures such as cam-slide rod transmission and worm gear-thread rod transmission, solves the problems of loose structure, complex transmission chain and high failure rate of some multi-functional equipment, and achieves the technical effect of compact structure, stable and reliable operation and easy maintenance.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0023] Example: Please refer to Figures 1 to 4This utility model provides a sweet potato crusher, which aims to solve the problems of low efficiency caused by the need for manual cutting before crushing sweet potatoes and high energy consumption during outdoor operations in the prior art.

[0024] like Figure 1 and Figure 2 As shown, a sweet potato crusher includes a body 1 and a hopper 4 disposed on the upper part of the body 1, and a partition 5 movably disposed between the hopper 4 and the body 1; the sweet potato crusher further includes a cutting mechanism 2 disposed between the hopper 4 and the partition 5, and an energy-saving mechanism 3 that can be unfolded and connected to the outer wall of the body 1; during operation, the sweet potato to be crushed first enters from the hopper 4, and is automatically cut into pieces by the cutting mechanism 2. The cut sweet potato pieces fall into the body 1 through the partition 5 for final crushing, and the energy-saving mechanism 3 can be unfolded when needed to absorb solar energy to power the equipment.

[0025] Specifically, refer to Figure 3 and Figure 4 The cutting mechanism 2 is for automatic cutting and includes a support plate 201. A slide rod 202, capable of reciprocating up and down, is slidably connected within the support plate 201. A cutting blade 203 for chopping sweet potatoes is fixedly connected to the bottom end of the slide rod 202. The cutting mechanism 2 also includes a drive assembly 204, which provides power for the movement of the cutting blade 203. The drive assembly 204 includes a servo motor 2041 fixed to one side of the support plate 201. A cam 2043 is rotatably connected to the output end of the servo motor 2041. The contour surface of the cam 2043 abuts against the top end of the slide rod 202, thereby powering the servo motor 2041. The rotational motion is efficiently converted into the reciprocating linear motion of the slide bar 202. To ensure that the slide bar 202 can reliably return to its original position, the drive assembly 204 also includes a spring 2044. The spring 2044 is sleeved on the outer periphery of the slide bar 202, and its two ends abut against the inner wall of the support plate 201 and the flange fixed on the slide bar 202, respectively. The elastic force of the spring 2044 pushes the slide bar 202 back to its initial position. In addition, to protect the transmission components, the drive assembly 204 also includes a hollow long block 2042. The hollow long block 2042 is fixed on the support plate 201 and houses the cam 2043 inside it to prevent external impurities from affecting its movement.

[0026] Please refer to Figure 1 , Figure 2 and Figure 4The energy-saving mechanism 3 is used to absorb solar energy to provide power to the equipment during outdoor operation. It includes an expandable elongated frame plate 301, in which a solar panel 302 is fixed. The energy-saving mechanism 3 also includes a power component 303 for driving the elongated frame plate 301 to expand or retract. The power component 303 includes a hollow block 3032 fixed to the outer wall of the body 1, and a servo motor 3031 fixed to the outside of the hollow block 3032. A worm gear 3036 is fixedly connected to the output end of the servo motor 3031. A worm wheel 3033 is rotatably arranged inside the hollow block 3032 and meshes with the worm gear 3036. The worm wheel 3033 is coaxially fixed to the middle of a bidirectional threaded rod 3034. The two ends of the bidirectional threaded rod 3034 extend from the hollow block 3032 and are threadedly engaged with the elongated frame plate 301, respectively. The elongated frame plate 301 has corresponding... A threaded hole is provided to mate with the bidirectional threaded rod 3034. To ensure the stability of the elongated frame plate 301 during unfolding or retraction, the power assembly 303 also includes an elongated column 3035. The elongated column 3035 is set parallel to the bidirectional threaded rod 3034, and its two ends are fixed to the hollow block 3032. The elongated column 3035 passes through the guide hole opened on the elongated frame plate 301, and a sliding guide fit is formed between the elongated column 3035 and the guide hole. This transmission structure, which consists of the servo motor 3031, worm gear 3036, worm wheel 3033 and bidirectional threaded rod 3034, together with the guiding effect of the elongated column 3035, ensures that the solar panel 302 can unfold and retract smoothly and synchronously. Moreover, the worm gear 3036-worm wheel 3033 transmission has a self-locking characteristic, which allows the solar panel 302 to stay stably at any unfolding angle.

[0027] As a preferred embodiment, to ensure the stability and reliability of the cutting mechanism 2, the structure of the drive assembly 204 can be further optimized; please refer to... Figure 3 Spring 2044 is sleeved on the outer periphery of slide rod 202. The two ends of spring 2044 abut against the inner wall of support plate 201 and the integrally formed flange on slide rod 202, respectively. After the thrust of cam 2043 ends, spring 2044 uses its stored elastic potential energy to drive slide rod 202 and cutting blade 203 to quickly return to their original positions. At the same time, hollow block 2042 is fixed to support plate 201 by bolt connection and completely houses cam 2043 inside it to prevent material debris from affecting the transmission between cam 2043 and slide rod 202.

[0028] As another preferred embodiment, in order to maximize the utilization of solar energy and maintain the overall structural balance of the device, please refer to... Figure 1 and Figure 4The energy-saving mechanism 3 preferably includes two sets symmetrically arranged on both sides of the body 1; each set of energy-saving mechanism 3 includes an elongated frame plate 301 and a solar panel 302 installed therein; corresponding to this structure, a bidirectional threaded rod 3034 extends from the middle to both sides to form two sections of threads with opposite directions of rotation. These two sections of threads are respectively threaded into the threaded holes on the elongated frame plates 301 on both sides, thereby ensuring that when the bidirectional threaded rod 3034 rotates, it can synchronously drive the solar panels 302 on both sides to retract towards each other or unfold away from each other, with coordinated movement and stable structure.

[0029] In one specific structural layout of the power assembly 303, to achieve its modularity and compactness, a hollow block 3032 serves as the integrated base of the power assembly 303. The hollow block 3032 rotatably accommodates the worm gear 3033 and the middle part of the bidirectional threaded rod 3034, while the servo motor 3031 is fixed to the outer wall of the hollow block 3032, and the worm 3036 at its output end extends into the hollow block 3032 and meshes with the worm gear 3033. At the same time, the two ends of the elongated column 3035, which serves as a guide mechanism, are also fixed to the hollow block 3032 and are arranged parallel to the bidirectional threaded rod 3034, together forming a power module that integrates driving and guiding.

[0030] Working principle: When sweet potato cutting is required, the sweet potato to be cut is placed in the hopper 4, and then the servo motor 2041 in the drive assembly 204 is started. The servo motor 2041 drives the cam 2043 connected to its output end to rotate. During the rotation, the contour surface of the cam 2043 continuously pushes the top of the slide rod 202 in the support plate 201, forcing the slide rod 202 to move downward against the elastic force of the spring 2044. When the cam 2043 rotates past its highest point, the pushing force on the slide rod 202 disappears, and the slide rod 202 quickly returns to its original position under the action of the elastic force stored in the spring 2044. Through this repeated movement, the slide rod 202 drives the cutting blade 203 fixed at its bottom end to perform efficient reciprocating cutting motion in the hopper 4, cutting the sweet potato into pieces suitable for crushing. After cutting, the partition 5 is pulled open, and the material falls into the machine body 1 for final crushing.

[0031] When the device needs to utilize solar energy outdoors, the servo motor 3031 in the power assembly 303 is activated; the servo motor 3031 drives the worm gear 3036 to rotate, and the worm gear 3036 in turn drives the worm wheel 3033 meshing with it to rotate; since the worm wheel 3033 is coaxially fixed with the bidirectional threaded rod 3034, the bidirectional threaded rod 3034 rotates accordingly; since the two threads of the bidirectional threaded rod 3034 have opposite directions of rotation, when it rotates, it will drive the elongated frame plates 301 on both sides to move outward or inward along the elongated column 3035, which serves as a guide rail, through thread engagement to synchronously drive them to expand or contract; this process allows the solar panels 302 installed in the elongated frame plates 301 to fully expand to absorb light energy to the maximum area, or to compactly contract during transportation and storage.
