Abstract

The present invention relates to a weeding pulverizer, comprising a motor 1 and a transmission column, wherein the motor 1 is mounted on the upper side of a holding frame, a handle is mounted on the outer periphery of the holding frame, the head of the transmission column extends into the inner side of the holding frame and is connected to the output head of the motor 1, a crushing unit is mounted on the lower side of the transmission column, and a weeding unit is arranged in a circular array on the outer periphery of the crushing unit. The weeding range or mowing capacity can be increased by adjusting the diameter of a cutting assembly composed of a crushing unit and a weeding unit. An increase in the diameter of the cutting assembly will greatly increase the mowing range of the weeding unit when it rotates, but obstacles will also increase accordingly. Encountering grass stems that are difficult to remove will cause the weeding efficiency of the device to decrease or even get stuck.

Description

Technical Field

[0001] The invention belongs to the field of weeding pulverizers, in particular to a weeding pulverizer. Background Art

[0002] The lawn mower will gradually roll up the grass stems and leaves during the weeding process, resulting in inefficient weeding and difficulty in removal. There are great risks during removal and it is easy to scratch fingers. However, few current lawn mowers can automatically complete the cleaning conveniently and quickly. Therefore, a weed crusher is proposed. Summary of the invention

[0003] The purpose of this section is to summarize some aspects of embodiments of the present invention and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and the specification abstract and the invention title of this application to avoid blurring the purpose of this section, the specification abstract and the invention title, and such simplifications or omissions cannot be used to limit the scope of the present invention.

[0004] In view of the following technical problems in the prior art: the weeding efficiency is low and it is difficult to remove, there are great risks during removal and it is easy to scratch fingers, and the current weeders rarely complete the cleaning automatically and quickly.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: a weeding shredder, comprising a motor 1 and a power column, wherein the motor 1 is mounted on the upper side of a holding frame, a handle is mounted on the outer periphery of the holding frame, the head of the power column extends into the inner side of the holding frame and is connected to the output head of the motor 1, a crushing unit is mounted on the lower side of the power column, and weeding units are arranged in a circular array on the outer periphery of the crushing unit, and the number of the weeding units is X.

[0006] The value of X ranges from 4 to 6.

[0007] As a preferred technical solution of a weeding pulverizer, the outer periphery of the crushing unit is surrounded by X-shaped rectangular blocks connected end to end, and the power component inside the crushing unit;

[0008] A power assembly is installed in the crushing unit, and the power assembly includes a power transmission column and a vertical column. A servo motor is arranged at the tail of the vertical column. The output head of the servo motor is equipped with a second rotary disk. One end of the power transmission column is equipped with a first rotary disk. The rotary disks are engaged with the second rotary disk. Several power transmission disks and power transmission columns are connected in the crushing unit. The power transmission column is fixedly sleeved with spiral teeth. The outer ring of the power transmission disk is equipped with transmission teeth. The spiral teeth are engaged with the transmission teeth.

[0009] Each rectangular surface of the material-crushing unit is connected to a weeding unit, and the weeding unit comprises a rotating column, one end of which penetrates into the material-crushing unit, and the rotating column is fixedly connected to the power transmission disc.

[0010] The servo motor controls the rotation of the second rotary disk, and the second rotary disk drives the first rotary disk to rotate. The first rotary disk uses the power transmission column to drive the power transmission disk and the rotating column to rotate, so that the weeding unit rotates to complete the posture adjustment;

[0011] Since the spiral tooth structure on the power transmission column makes it impossible for the power transmission disc to drive the power transmission column to rotate, it is impossible to directly act on the weeding unit through external force to change the posture of the weeding unit.

[0012] As a preferred technical solution for a weed pulverizer, both the second disc and the first disc are umbrella discs, the first disc is arranged with the large diameter end below the small diameter end, and the second disc faces the opposite direction to the first disc.

[0013] The structures of turntable 2 and turntable 1 limit each other, which prevents turntable 1 from moving upward, thereby limiting the possible upward movement of the power transmission column.

[0014] As an optimal technical solution for a weeding shredder, the weeding unit includes a rectangular block, which is connected to the outer periphery of the crushing unit and is screwed to the crushing unit. A restraining pin is installed on the rectangle of the crushing unit, and the restraining pin is in movable abutment with the rectangular block.

[0015] The extension size of the weeding unit is positively correlated with the angle at which the rectangular block deviates from the horizontal plane, and the restraining pin can limit the swing amplitude of the rectangular block.

[0016] As a preferred technical solution of a weeding pulverizer, a cleaning column is installed on each rectangle of the crushing unit, and the cleaning column and the rectangular block do not interfere with each other. The cleaning column is composed of a top block and a straight cylinder. The inner sides of the crushing unit and the straight cylinder are chambers that can hold liquid. The top block is installed on the straight cylinder, and a plurality of drainage channels are also recessed on the straight cylinder. The straight cylinder is connected to a liquid supply pipeline.

[0017] The top block is in a truncated cone shape, and the small round surface of the top block is connected to the straight cylinder.

[0018] As a preferred technical solution of a weeding pulverizer, the four upper corners of the rectangular block are all configured with sharp corners;

[0019] The pointed movable sleeve is connected to an outer jacket, and the material of the outer jacket is polyethylene.

[0020] The crushing unit and the weeding unit rotate, and the cleaning column can reduce the grass stems and leaves from being wound around the root of the rectangular block and the connection part of the crushing unit to avoid the rectangular block from getting stuck. The top block on the cleaning column can roll up the stems and leaves, and then the cleaning column can generate a jet to cut the wound stems and leaves to remove them.

[0021] The servo motor is used to control the breaking frame and the rectangular block to swing back and forth at a high frequency. The blade cuts and pulls off the stems and leaves between the weeding units and between the weeding units and the cleaning columns, so that the stems and leaves are separated and the weeding units and the cleaning columns are cleaned of impurities.

[0022] As an optimal technical solution for a weeding pulverizer, a crushing frame is installed in the rectangular block, a recovery channel is recessed at one end of the crushing frame away from the crushing unit, one end of the extension frame extends into the recovery channel, a square column is installed in the inner cavity of the extension frame, the square column is fixedly connected to a rectangular beam 1, the wire of the rectangular beam 1 is connected to a rotating column, the wire on the rotating column is connected to a rectangular beam 2, and the rectangular beam 1 and the rectangular beam 2 are both variably connected to the rectangular channel opened in the inner cavity of the crushing frame;

[0023] The power transmission disc controls the rotating column to make a complete circular motion, and locks the posture of the crushing frame so that the crushing frame cannot deflect, and is connected to the rectangular beam through the rotating column;

[0024] The rectangular channel of the crushing frame limits the rotation of rectangular beam 1, so that rectangular beam 1 can only move along the axial direction of the rotating column. The rotation of the rotating column causes rectangular beam 1 and rectangular beam 2 to move in the inner cavity of the crushing frame, and rectangular beam 1 moves outward or inward, thereby extending or shortening the weeding unit.

[0025] As a preferred technical solution of a weeding pulverizer, the weeding unit contains two groups of stacked supplementary blocks, which are arranged on both sides of a square column or a rectangular beam. The cross-section of the supplementary blocks is a parallelogram. The supplementary blocks arranged on both sides of the square column or the rectangular beam correspond to each other, and two rubber bands are connected between the corresponding supplementary blocks. The two rubber bands on each supplementary block are respectively passed around the two sides of the outer periphery of the square column or the rectangular beam. The square column is located at one end of the recycling channel and is preset as an inclined surface, which is variably connected to the supplementary block.

[0026] The supplementary block located at the innermost side of the extension frame abuts against the elastic member, and one end of the supplementary block away from the elastic member is pressed against the inner cavity wall of the extension frame.

[0027] The servo motor controls the rotation of the second turntable, and the second turntable rotates with the first turntable. The first turntable uses the power transmission column to drive the power transmission disk and the rotating column to rotate. If the crushing frame and the rectangular block are not constrained and locked, the rotating column drives the crushing frame to swing to change the posture of the crushing frame.

[0028] The crushing frame may be blocked by the restraining pin installed on the outer ring of the crushing unit. If the rectangular block is threaded with a bolt and one end of the bolt is frictionally connected with the outer periphery of the crushing unit and locked, the rectangular block will also be locked. Therefore, after the crushing frame and the rectangular block are constrained or locked, the rotating column can overcome the obstacle and drive the rectangular beam 2 and the rectangular beam 1 to move along the axis of the rotating column, so that the extended frame moves out of the recovery channel. As the extended frame moves out, a vacancy is generated in the recovery channel, and the elastic member pushes the supplementary block to occupy the vacancy in the recovery channel. The supplementary blocks entering the recovery channel are pulled together by the rubber band rope. The supplementary blocks are stacked together to resist the inclined surface of the square column, and the radial movement of the extended frame and the rectangular beam 1 is blocked and difficult to shake, thereby making the extended frame and the rectangular beam 1 more stable.

[0029] The pipeline connected to the cleaning column is passed through high-pressure water, and the drainage channel on the cleaning column can generate a jet to cut the wound stems and leaves so that they can be removed.

[0030] The beneficial effects of the weeding pulverizer of the present invention are as follows: by adjusting the diameter of the cutting assembly composed of the crushing unit and the weeding unit, the weeding range or mowing capacity can be increased. The increase in the diameter of the cutting assembly will greatly increase the mowing range of the weeding unit when it rotates, but the obstacles will also increase. When encountering grass stems that are difficult to remove, the weeding efficiency of the device will decrease or even get stuck. In this case, the size of the weeding unit can be shortened to enhance the cutting capacity.

[0031] By controlling the swing of the breaking frame and the rectangular block, the blade cuts and pulls off the stems and leaves rolled between the weeding units and between the weeding units and the cleaning columns, thereby separating the stems and leaves and removing impurities from the weeding units and the cleaning columns. High-pressure water is introduced through the pipeline connected to the cleaning columns, and the drainage channel on the cleaning columns can generate a jet to cut the rolled stems and leaves so that they are removed, thereby achieving the purpose of automatic cleaning.

DETAILED DESCRIPTION

[0044] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0045] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0046] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0047] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0048] like Figure 1-10 As shown, the present invention proposes a weeding shredder, including a motor 12 and a power column 14, wherein the motor 12 is mounted on the upper side of a holding frame 13, a handle 18 is mounted on the periphery of the holding frame 13, the head of the power column 14 extends into the inner side of the holding frame 13 and is connected to the output head of the motor 12, a crushing unit 15 is mounted on the lower side of the power column 14, and weeding units 16 are arranged in a circular array on the periphery of the crushing unit 15, and the number of the weeding units 16 is X.

[0049] The value of X ranges from 4 to 6.

[0050] As a preferred technical solution of a weeding pulverizer, the outer periphery of the crushing unit 15 is surrounded by X-shaped rectangular blocks connected end to end, and the power component inside the crushing unit 15;

[0051] A power assembly is installed in the crushing unit 15, and the power assembly includes a power transmission column 1504 and a vertical column 1507. A servo motor 1506 is arranged at the tail of the vertical column 1507. A turntable 2 1505 is installed at the output head of the servo motor 1506. A turntable 1508 is installed at one end of the power transmission column 1504. The turntable 1 1508 is engaged with the turntable 2 1505. Several power transmission disks 1503 and power transmission columns 1504 are screwed together in the crushing unit 15. Spiral teeth are fixedly mounted on the power transmission column 1504. Transmission teeth are installed on the outer ring of the power transmission disk 1503. The spiral teeth are engaged with the transmission teeth.

[0052] Each rectangular surface of the material-crushing unit 15 is connected to a weeding unit 16 , and the weeding unit 16 includes a rotating column 1604 , one end of which penetrates into the material-crushing unit 15 , and the rotating column 1604 is fixedly connected to the power transmission disc 1503 .

[0053] The servo motor 1506 controls the rotation of the second rotary disk 1505, and the second rotary disk 1505 rotates the first rotary disk 1508. The first rotary disk 1508 uses the power transmission column 1504 to drive the power transmission disk 1503 and the rotating column 1604 to rotate, so that the weeding unit 16 rotates to complete the posture adjustment.

[0054] Since the spiral tooth structure on the power transmission column 1504 makes it impossible for the power transmission disc 1503 to drive the power transmission column 1504 to rotate, it is impossible to directly act on the weeding unit 16 through external force to change the posture of the weeding unit 16.

[0055] As a preferred technical solution for a weed pulverizer, both disc 2 1505 and disc 1 1508 are umbrella discs. Disc 1 1508 is arranged with its large diameter end below its small diameter end, and disc 2 1505 faces opposite to disc 1 1508.

[0056] The structures of turntable 2 1505 and turntable 1 1508 limit each other, so that turntable 1 1508 cannot move upward, thereby limiting the possible upward movement of the power transmission column 1504.

[0057] As an optimal technical solution for a weeding shredder, the weeding unit 16 includes a rectangular block 1602, which is connected to the outer periphery of the crushing unit 15, and the rectangular block 1602 is screwed to the crushing unit 15. A restraining pin is installed on the rectangle of the crushing unit 15, and the restraining pin is in movably abutted against the rectangular block 1602.

[0058] The extension size of the weeding unit 16 is positively correlated with the angle at which the rectangular block 1602 deviates from the horizontal plane.

[0059] The restraining pins can limit the swing amplitude of the rectangular block 1602 .

[0060] As a preferred technical solution of the weeding pulverizer, a cleaning column 1502 is installed on each rectangle of the crushing unit 15, and the cleaning column 1502 does not interfere with the rectangular block 1602. The cleaning column 1502 is composed of a top block 1510 and a straight cylinder 1509. The inner sides of the crushing unit 15 and the straight cylinder 1509 are chambers that can accommodate liquids. The top block 1510 is installed on the straight cylinder 1509, and a plurality of drainage channels 1511 are also recessed on the straight cylinder 1509. The straight cylinder 1509 is connected to a liquid supply pipeline.

[0061] The top block 1510 is in the shape of a truncated cone, and the small round surface of the top block 1510 is connected to the straight cylinder 1509;

[0062] The four upper corners of the rectangular block 1602 are all configured with sharp corners 1610;

[0063] The height of the top block 1510 is three times that of the straight tube 1509;

[0064] The pointed corner 1610 is movably connected to a jacket, and the material of the jacket is polyethylene.

[0065] The crushing unit 15 and the weeding unit 16 rotate, and the cleaning column 1502 can reduce the grass stems and leaves from being wound around the root of the rectangular block 1602 and the connection part of the crushing unit 15, and the top block 1510 on the cleaning column 1502 can roll up the stems and leaves, and then the cleaning column 1502 can generate a jet to cut the wound stems and leaves to remove them, so as to avoid the rectangular block 1602 from getting stuck;

[0066] The servo motor 1506 is used to control the breaking frame 1601 and the rectangular block 1602 to swing back and forth at a high frequency, and the blade cuts and pulls off the stems and leaves between the weeding units 16 and the stems and leaves between the weeding units 16 and the cleaning column 1502, thereby separating the stems and leaves and removing impurities from the weeding units 16 and the cleaning column 1502.

[0067] As an optimal technical solution for a weeding shredder, a crushing frame 1601 is installed in the rectangular block 1602, and a recovery channel 1603 is recessed at one end of the crushing frame 1601 away from the crushing unit 15. One end of the extension frame 1612 extends into the recovery channel 1603, and a square column 1615 is installed in the inner cavity of the extension frame 1612. The square column 1615 is fixedly connected to a rectangular beam 1607, and the wire of the rectangular beam 1607 is connected to a rotating column 1604, and the wire of the rotating column 1604 is connected to a rectangular beam 2 1608. The rectangular beam 1607 and the rectangular beam 2 1608 are both variably connected to the rectangular channel opened in the inner cavity of the crushing frame 1601.

[0068] The power transmission disk 1503 controls the rotating column 1604 to make a complete circular motion, by locking the posture of the breaker frame 1601 so that the breaker frame 1601 cannot deflect, and the rotating column 1604 is threadedly connected with the rectangular beam 1 1607; the rectangular channel of the breaker frame 1601 limits the rotation of the rectangular beam 1 1607, so that the rectangular beam 1 1607 can only move along the axial direction of the rotating column 1604, and the rotation of the rotating column 1604 causes the rectangular beam 1 1607 and the rectangular beam 2 1608 to move in the inner cavity of the breaker frame 1601, and the rectangular beam 1 1607 moves outward or inward, thereby extending or shortening the weeding unit 16.

[0069] The weeding unit 16 contains two groups of stacked supplementary blocks 1605, which are arranged on both sides of the square column 1615 or the rectangular beam 1607. The cross section of the supplementary blocks 1605 is a parallelogram. The supplementary blocks 1605 arranged on both sides of the square column 1615 or the rectangular beam 1607 correspond to each other, and two rubber bands 1606 are connected between the two corresponding supplementary blocks 1605. The two rubber bands 1606 on each supplementary block 1605 go around the two sides of the outer periphery of the square column 1615 or the rectangular beam 1607 respectively. The end of the square column 1615 located at the recycling channel 1603 is preset as an inclined surface, and the inclined surface is variably connected to the supplementary block 1605.

[0070] The supplementary block 1605 located at the innermost side of the extension frame 1612 abuts against the elastic member 1614 , and one end of the supplementary block 1605 away from the elastic member 1614 is pressed against the inner cavity wall of the extension frame 1612 .

[0071] The servo motor 1506 controls the rotation of the second turntable 1505, and the second turntable 1505 rotates the first turntable 1508. The first turntable 1508 uses the power transmission column 1504 to drive the power transmission disk 1503 and the rotating column 1604 to rotate. If the crushing frame 1601 and the rectangular block 1602 are not constrained and locked, the rotating column 1604 drives the crushing frame 1601 to swing to change the posture of the crushing frame 1601.

[0072] The crushing frame 1601 may be blocked by the restraining pins installed on the outer ring of the crushing unit 15. If the rectangular block 1602 is threaded with the bolt 1613, and one end of the bolt 1613 is frictionally connected with the outer periphery of the crushing unit 15 and locked, the rectangular block 1602 will also be locked. Therefore, after the crushing frame 1601 and the rectangular block 1602 are restrained or locked, the rotating column 1604 can overcome the obstacles and drive the rectangular beam 2 1608 and the rectangular beam 1 1607 to move along the axis of the rotating column 1604, so that the extension frame 1612 moves out of the recycling passage. Channel 1603, as the extension frame 1612 is moved out, a vacancy is generated in the recycling channel 1603, and the elastic member 1614 pushes the supplementary block 1605 to occupy the vacancy in the recycling channel 1603, and the supplementary blocks 1605 entering the recycling channel 1603 are pulled together by the rubber band 1606, and the supplementary blocks 1605 are stacked together to resist the inclined surface of the square column 1615, and the radial movement of the extension frame 1612 and the rectangular beam 1607 is blocked and difficult to shake, so that the extension frame 1612 and the rectangular beam 1607 are more stable;

[0073] High-pressure water is introduced into the pipeline connected to the cleaning column 1502, and the drainage channel 1511 on the cleaning column 1502 can generate a jet to cut the wrapped stems and leaves so that they can be cleared.

[0074] The same side of the breaking frame 1601 and the rectangular block 1602 is set as a blade.

[0075] A handle 18 is installed on the periphery of the holding frame 13. When the rotating column 1604 rotates, when the rectangular block 1602 is not locked, the rotating column 1604 drives the rectangular beam 1607 to move the rectangular block 1602 out of the recovery channel 1603. The resistance is greater than the resistance of the deflection of the crushing frame 1601, so the rotating column 1604 can preferentially drive the crushing frame 1601 to deflect.

[0076] The elastic member 1614 is a spring, and the power transmission disc 1503 and the power transmission column 1504 are common worm gears.

[0077] The specific implementation method is as follows: holding the handle 18, starting the motor 12 to control the power column 14 to rotate, the power column 14 rotates the breaking frame 1601 through the crushing unit 15, and controls the blade of the breaking frame 1601 to contact the weeds, cut and break the stems and leaves of the grass, and scatter them on the ground, thereby achieving the purpose of weeding;

[0078] In the interval of weeding, the artificial locking is released, and the locking effect of the bolt 1613 or other means on the rectangular block 1602 is released. Since the rectangular beam 1607 and the rotating column 1604 are threaded together and are subject to great resistance, the rotating column 1604 will apply a great torque to the crushing frame 1601 through the rectangular beam 1607 during the rotation process, so that the servo motor 1506 and the power component can be used to control the crushing frame 1601 and the rectangular block 1602 to swing back and forth at a high frequency. The blade of the crushing frame 1601 cuts off or breaks the stems and leaves rolled between the crushing frames 1601 and the stems and leaves between the crushing frame 1601 and the cleaning column 1502, so that the stems and leaves are separated, and the crushing frame 1601 and the cleaning column 1502 are cleaned, and the pipeline connected to the cleaning column 1502 is passed with high-pressure water, and the drainage channel 1511 on the cleaning column 1502 can generate a jet to cut the wound stems and leaves so that they are removed.

[0079] It will be appreciated that in the development of any actual implementation, as in any engineering or design project, numerous implementation-specific decisions may be made. Such a development effort may be complex and time-consuming, but will be a routine task of design, fabrication, and production for those of ordinary skill having the benefit of this disclosure without undue experimentation.

[0080] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
