Description

Technical Field

[0001] This application relates to the technical field of sand control machinery, and in particular to a tracked integrated machine for pressing grass and covering sand. Background Technology

[0002] A straw pressing and sand covering machine is a device that assists in inserting straw into sandy soil. It typically has rotating rollers that, as the machine moves, press the straw laid on the sand into the center, achieving a tight bond between the straw and the sand to form a sand barrier. However, because straw pressing usually requires manual or auxiliary equipment to pre-lay the straw before using the straw pressing and sand covering machine, the process becomes more complicated, reducing overall operational efficiency. Summary of the Invention

[0003] In order to improve the overall efficiency of grass pressing, this application provides a tracked grass pressing and sand covering machine.

[0004] This application provides a tracked integrated machine for pressing grass and covering sand, which adopts the following technical solution:

[0005] A tracked integrated grass pressing and sand covering machine includes: a pulling mechanism and a grass pressing mechanism, wherein the pulling mechanism is used to drive the grass pressing mechanism to move; the grass pressing mechanism includes...

[0006] The connecting frame is connected to the pulling mechanism;

[0007] The walking wheels are rotatably connected to the connecting frame via a rotating shaft;

[0008] A hay pressing disc, connected to the rotating shaft, is coaxially arranged with and rotates together with the traveling wheel. The outer diameter of the hay pressing disc is larger than the outer diameter of the traveling wheel. Multiple receiving openings for hay to enter are evenly spaced along the outer circumference of the hay pressing disc.

[0009] The feed hopper is installed on the connecting frame and forms an upward-facing feeding cavity. It also has a clearance opening for the upper part of the pressing disc to enter the feeding cavity and a discharge port communicating with the clearance opening. The discharge port is used to remove the straw in the receiving cavity from the discharge port from the feed hopper when the pressing disc rotates.

[0010] By adopting the above technical solution, the forage is fed into the hopper and falls into the receiving opening of the pressing disc. When the pulling mechanism drives the pressing mechanism to move, the traveling wheels roll on the sand to drive the pressing disc to roll synchronously, thereby bringing the forage on the pressing disc out of the hopper and inserting it into the sand. This achieves the synchronous laying of forage and pressing, improves the continuity of operation, and increases the overall operation efficiency.

[0011] Optionally, the grass-pressing mechanism has at least two sets, and the connecting frame of both sets of grass-pressing mechanisms is hinged to the pulling mechanism.

[0012] By adopting the above technical solution, at least two sets of grass pressing mechanisms have increased the coverage area of ​​a single operation, further improving operational efficiency.

[0013] Optionally, the grass-pressing mechanism can be detachably connected to the pulling mechanism.

[0014] By adopting the above technical solution, the grass pressing mechanism can be detachably connected to the pulling mechanism, which facilitates flexible configuration according to different operational needs and terrain conditions, thereby improving the applicability and maintainability of the equipment.

[0015] Optionally, the pulling mechanism includes a traction machine and a hay-placing platform, the hay-placing platform being mounted on the traction machine for placing hay, and the connecting frame being connected to the hay-placing platform.

[0016] Optionally, the connecting frame is hinged to the pulling mechanism. The grass pressing and sand covering machine also includes a lifting mechanism. The lifting mechanism includes a vertical pole, a rope component, and a winder. The vertical pole is fixedly installed on the pulling mechanism. The winder is installed on the vertical pole and is used to wind and unwind the rope component. The end of the rope component away from the winder is wound around the vertical pole and connected to the connecting frame and / or the feed hopper.

[0017] By adopting the above technical solution and setting up the lifting mechanism, the height and angle of the grass pressing mechanism can be adjusted as needed, so that the grass pressing mechanism can be turned away from the sand after the grass pressing operation is completed, thus enhancing the flexibility of the equipment.

[0018] Optionally, the straw pressing mechanism further includes a scraper plate, which is fixed in the straw pressing disc and opposite to the discharge port, and the scraper plate abuts against the outer peripheral wall of the straw pressing disc located in the feeding chamber.

[0019] By adopting the above technical solution, the scraper can scrape off the straw from the pressing disc except for the receiving opening, thereby improving the uniformity of the straw distributed at intervals on the pressing disc, and thus improving the uniformity of the formed straw and sand barrier.

[0020] Optionally, the straw pressing mechanism further includes a baffle, one end of which is connected to the scraper plate, and the other end of which extends out of the feed hopper from the discharge port. The baffle extends circumferentially along the straw pressing disc and is close to the outer periphery of the forward end of the straw pressing disc, and the bottom of the baffle is close to the bottom of the traveling wheel.

[0021] By adopting the above technical solution, the baffle prevents the hay from falling off the hay pressing disc during the process of the hay pressing disc carrying the hay out.

[0022] Optionally, a pusher plate corresponding to each of the receiving openings is moved radially along the tamp disc in the tamp disc, and an abutment rod extending to the outside of the tamp disc is connected to one end of the pusher plate near the rotating shaft.

[0023] The connecting frame is connected to an adjusting member that surrounds the rotating shaft. The adjusting member includes, in sequence along the circumference of the rotating shaft, a first adjusting section, a first transition section, a second adjusting section, and a second transition section. The outer peripheral walls of the first adjusting section and the second adjusting section extend coaxially with the rotating shaft, and the outer diameter of the first adjusting section is smaller than that of the second adjusting section. The first transition section and the second transition section are both located between the first adjusting section and the second adjusting section, and the first transition section and the second transition section are respectively located at opposite ends of the first adjusting section. The outer peripheral walls of the first transition section and the second transition section smoothly transition from the outer peripheral wall of the first adjusting section to the outer peripheral wall of the second adjusting section.

[0024] When the grass pressing disc rotates, the abutting rod is magnetically attracted to the outer peripheral wall of the first adjusting section, the first transition section, the second adjusting section, and the second transition section in sequence. When the receiving port on the grass pressing disc is located below the bottom of the pressing wheel, the abutting rod corresponding to the receiving port abuts against the first transition section, the second adjusting section, and the second transition section in sequence.

[0025] When the abutting rod abuts against the outer peripheral wall of the first adjusting section, the adjusting piece retracts into the tamp disc. When the abutting rod abuts against the outer peripheral wall of the second adjusting section, the adjusting piece extends into the receiving opening, and the end of the adjusting piece away from the abutting rod approaches the outer peripheral wall of the tamp disc.

[0026] By adopting the above technical solution, the design of the pusher plate, the abutment rod, and the adjusting parts enables dynamic adjustment of the straw in the receiving opening, so that the straw can enter the sandy land evenly and quantitatively. During the process of the straw pressing disc rotating out of the sandy land, it is not easy to carry the straw out of the sandy land again, thus improving the straw pressing effect.

[0027] Optionally, an abutment ring is detachably connected to the outer wall of the first adjustment section for magnetic attraction of the abutment rod. The abutment ring is arc-shaped. The inner wall of the abutment ring is attached to the outer wall of the first adjustment section so as to be coaxial with the first adjustment section. The two ends of the abutment ring are far apart from each other and abut against the outer walls of the first transition section and the second transition section respectively. The outer diameter of the abutment ring is smaller than the outer diameter of the second adjustment section.

[0028] By adopting the above technical solution, the outer diameter of the first adjustment section can be increased by installing the abutment ring on the first adjustment section. When the abutment rod abuts against the abutment ring, the pusher plate is pushed into the receiving opening to adjust the size of the receiving opening, thereby adjusting the amount of straw entering the receiving opening and further improving the adaptability of the equipment.

[0029] In summary, this application includes at least one of the following beneficial effects:

[0030] 1. The pressing disc is equipped with a receiving opening so that when the traveling wheels move on the sand, they drive the pressing disc, which contains grass, to rotate and move together. The pressing disc can continuously insert grass into the sand, and the laying and insertion of grass are carried out at the same time, thereby improving the continuity and efficiency of the operation. In addition, the equipment has a compact structure, is lightweight, and is easy to move.

[0031] 2. By hinged the connecting frame to the pulling mechanism, the components of the grass pressing mechanism can be lifted off the sand surface by the lifting mechanism, so that the grass pressing mechanism can be stored after the grass pressing is completed.

[0032] 3. The cooperation between the pusher plate and the adjusting component allows the pusher plate to automatically push the grass into the sand into the pressing disc during the movement of the pressing disc, further assisting the grass in the action of inserting it into the sand and improving the pressing effect.

[0041] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0042] Example 1:

[0043] This application discloses a tracked integrated machine for pressing grass and covering sand. (Refer to...) Figure 1 The grass pressing and sand covering machine includes a pulling mechanism 1, a lifting mechanism 8, and a grass pressing mechanism 2. The grass pressing mechanism 2 is hinged to the pulling mechanism 1. The pulling mechanism 1 drives the grass pressing mechanism 2 forward on the sand to bring the grass to and press it into the sand. The lifting mechanism 8 is installed between the pulling mechanism 1 and the grass pressing mechanism 2, so as to drive the grass pressing mechanism 2 to rotate relative to the pulling mechanism 1 to the use state and the storage state.

[0044] The pulling mechanism 1 includes a traction machine 101 and a grass-laying platform 102. The traction machine 101 is a conventional tracked traction machine used to provide power for the entire machine to move forward on the sand. The grass-laying platform 102 is a square plate fixed to the body of the traction machine 101, and the plate surface of the grass-laying platform 102 extends horizontally. The operator can sit on the grass-laying platform 102, and the grass-laying platform 102 is also used to place the grass that needs to be inserted into the sand.

[0045] Reference Figure 1 and Figure 2 The grass pressing mechanism 2 has two sets, which are arranged horizontally along the walking direction of the vertical traction machine 101 and connected to the grass placement platform 102. Each set of grass pressing mechanism 2 includes a connecting frame 201, a walking wheel 202, a grass pressing disc 203, a feed hopper 204, and a scraper 205.

[0046] The connecting frame 201 is a hollow frame, with one end hinged to the end of the grass-laying platform 102 away from the forward direction of the tractor 101. A rotating shaft 3 is rotatably connected to the bottom of the connecting frame 201 via a bearing seat (not shown in the figure). The axis of the rotating shaft 3 is parallel to the distribution direction of the two sets of grass-pressing mechanisms 2. One end of the rotating shaft 3 extends from the side of the connecting frame 201 away from the other set of grass-pressing mechanisms 2 and is fixed to the traveling wheel 202. The traveling wheel 202 is coaxially fitted onto the outer wall of the rotating shaft 3. The traveling wheel 202 is a rubber tire with a rough, raised stripe surface for walking on sand.

[0047] Reference Figure 2 The grass-pressing disc 203 is disc-shaped and coaxially mounted and fixed to the rotating shaft 3, ensuring that the grass-pressing disc 203 and the rotating shaft 3 are coaxial. The outer diameter of the grass-pressing disc 203 is larger than the outer diameter of the traveling wheel 202, so that when the traveling wheel 202 rolls on the sand, the lower part of the grass-pressing disc 203 embeds into the sand, and the traveling wheel 202 drives the grass-pressing disc 203 to rotate synchronously via the rotating shaft 3. It should be noted that the grass-pressing disc 203 has multiple evenly spaced receiving openings 4 along its circumference. These openings 4 are used to insert grass, allowing the grass to be carried into the sand as the grass-pressing disc 203 rotates.

[0048] Reference Figure 1 and Figure 2 The feed hopper 204 is a square box-shaped structure forming an upward-opening material placement chamber 5, and the bottom of the feed hopper 204 is fixed to the top of the connecting frame 201. The bottom of the feed hopper 204 has a clearance opening 6 and a discharge opening 7 that communicate with the material placement chamber 5. The discharge opening is located on the side of the feed hopper 204 closest to the straw placement platform 102, and the discharge opening 7 extends along the axis parallel to the straw pressing disc 203, with an extension length greater than the length of the straw. The clearance opening 6 connects to the side of the discharge opening 7 away from the straw placement platform 102, and its length extends perpendicular to the axis of the straw pressing disc 203 and away from the straw placement platform 102. The extension thickness of the clearance opening 6 along the axis parallel to the straw pressing disc 203 is slightly greater than the thickness of the straw pressing disc 203.

[0049] The top of the straw pressing disc 203 extends into the feed hopper 204 through the clearance port 6 on the side away from the straw placement platform 102, while the top of the straw pressing disc 203 extends into the feed hopper 204 through the discharge port 7 on the side close to the straw placement platform 102, and the straw pressing disc 203 is located in the middle of the discharge port 7.

[0050] Reference Figure 1 and Figure 3The scraper 205 is square and fixed in the feed hopper 204. Specifically, the scraper 205 is fixed to the inner walls of the feed hopper 204 on opposite sides along the axis parallel to the pressing disc 203. The scraper 205 extends vertically and is located above the discharge port 7. Simultaneously, the lower surface of the scraper 205 abuts against the outer peripheral wall of the pressing disc 203 to scrape away the straw outside the receiving opening 4 of the pressing disc 203.

[0051] When the grass pressing and sand covering machine is in use, the tractor 101 drives the grass pressing mechanism 2 to move on the sand. The connecting frame 201 rotates relative to the grass placing platform 102 under the gravity of each component in the grass pressing mechanism 2 until the walking wheel 202 abuts against the sand surface. At this time, the lower part of the grass pressing disc 203 is inserted into the sand. The traveling wheels 202 roll on the sand under the pulling force of the traction machine 101, driving the pressing disc 203 forward. Simultaneously, the operator places the straw from the placing platform 102 into the placing chamber 5 and applies downward pressure to press the straw against the pressing disc 203. The middle of the straw, subjected to downward pressure and its own weight, enters the receiving opening 4 of the pressing disc 203. As the pressing disc 203 rotates, it gradually carries the straw out from the discharge port 7, inserting the middle of the straw into the sand. As the pressing disc 203 rotates away from the sand, the straw is squeezed and rubbed by the sand, leaving it confined in the sand. Two operators can simultaneously feed the two sets of pressing mechanisms 2 into their feed hoppers 204, forming two parallel straw and sand barriers as the traction machine 101 moves.

[0052] Reference Figure 1 and Figure 4 Furthermore, to facilitate the maintenance and replacement of the straw-pressing mechanism 2, the connecting frame 201 is detachably connected to the straw-laying platform 102. Specifically, two connecting seats 13 are bolted to the tail of the straw-laying platform 102. The two connecting seats 13 are located near opposite sides of the straw-laying platform 102, and each connecting seat 13 is fitted with a screw 14, which is connected to the screw 14 by bolts. The screw 14 serves as a hinge for the connecting frame 201 to hinge onto the straw-laying platform 102. The connecting frame 201 is rotatably fitted onto the screw 14 and can move along the axis of the screw 14. Nuts 15 are threaded onto the screw 14, and each connecting frame 201 corresponds to two nuts 15. The two nuts 15 abut against opposite sides of the connecting frame 201 to restrict the upward movement of the connecting frame 201 along the screw 14 axis when the straw-pressing mechanism 2 is in use.

[0053] When the grass pressing mechanism 2 needs to be dismantled, one of the connecting seats 13 is removed from the grass placement platform 102 and separated from the screw 14. Then, the nut 15 and the connecting frame 201 are separated from the screw 14 in sequence to dismantle the grass pressing mechanism 2. In addition, the distance between the grass pressing discs 203 on the two grass pressing mechanisms 2 can be adjusted by adjusting the position of the nut 15, thereby improving the adaptability of the equipment.

[0054] Reference Figure 1 and Figure 4 The lifting mechanism 8 includes a vertical rod 81, a rope member 82, and a winder 83. The vertical rod 81 is fixed to the body of the traction machine 101 and extends inclined upwards towards the feed hopper 204. A fixed pulley is rotatably connected to the top of the vertical rod 81. The winder 83 is installed at the bottom of the vertical rod 81 for winding the rope member 82 and for winding and unwinding the rope member 82.

[0055] The rope assembly 82 includes a main rope 821 and a branch rope 822. One end of the main rope 821 is wound around the winder 83, and the other end of the main rope 821 extends along the upright 81 and passes over a fixed pulley. One end of the branch rope 822 is fixedly connected to the end of the main rope 821 away from the winder 83, and the other end of the branch rope 822 is connected to the end of the component in the straw pressing mechanism 2 away from the straw placement platform 102. In this embodiment, there are four branch ropes 822. Two branch ropes 822 are connected at the ends away from the main rope 821 to the connecting frame 201 and the feed hopper 204 in one set of grass pressing mechanisms 2, respectively. The other two branch ropes 822 are connected at the ends away from the main rope 821 to the connecting frame 201 and the feed hopper 204 in another set of grass pressing mechanisms 2, respectively. In other embodiments, there may be two branch ropes 822. The two branch ropes 822 are connected to the connecting frame 201 in two sets of grass pressing mechanisms 2, or to the feed hopper 204 in two sets of grass pressing mechanisms 2, respectively.

[0056] When pressing grass on sand, both the main rope 821 and the branch rope 822 are in a slack state, and the grass pressing mechanism 2 is in use. The rotation angle between the connecting frame 201 and the grass placement platform 102 can be adjusted automatically according to the undulation of the sand. After the grass pressing operation is completed, the main rope 821 is wound up, so that both the main rope 821 and the branch rope 822 are taut. The main rope 821 and the branch rope 822 pull the connecting frame 201 to rotate upward relative to the grass placement platform 102, so that the lowest point of each component in the grass pressing mechanism 2 is higher than the sand surface and the lowest point of the traction machine 101. At this time, the grass pressing mechanism 2 is in a retracted state, and when the traction machine 101 moves, the grass pressing mechanism 2 will not disturb the sand surface or the ground.

[0057] The implementation principle of a tracked grass pressing and sand covering integrated machine according to an embodiment of this application is as follows: When the tractor 101 moves on the sand, it drives the traveling wheels 202 and the grass pressing wheels to roll in the sand, feeding grass into the feed hopper 204 and pressing the grass down. The grass enters the receiving port 4 of the grass pressing wheel. When the grass pressing wheel rolls, it carries the grass out of the feed hopper 204 and inserts it into the sand, so as to realize the synchronous operation of feeding and inserting.

[0058] Example 2:

[0059] The difference between this embodiment and Embodiment 1 is that, referring to Figure 5, this embodiment further includes a baffle 206. The baffle 206 is in the shape of an arc plate, and the inner diameter of the baffle 206 is slightly larger than the outer diameter of the grass pressing disc 203. Specifically, the inner diameter of the baffle 206 is 1cm-2cm larger than the outer diameter of the grass pressing disc 203. In this embodiment, 1cm is selected.

[0060] The upper end of the baffle 206 is fixed to the bottom of the scraper 205, and the lower end of the baffle 206 extends from the discharge port 7 into the feed hopper 204. The lower end of the baffle 206 is also close to and higher than the bottom of the traveling wheel 202, so that the baffle 206 is less likely to come into contact with the sand surface. At the same time, the baffle 206 is coaxially arranged with the straw pressing disc 203 and is opposite to one side of the straw pressing disc 203 in the forward direction.

[0061] Therefore, when the straw pressing disc 203 carries the straw into and out of the hopper 204 through the receiving port 4, the straw is opposite to the baffle 206 during the downward movement, so that it is not easily affected by wind, gravity, etc. and leaves the straw pressing disc 203, thereby improving the stability of the straw on the straw pressing disc 203 when the straw pressing disc 203 is rotating.

[0062] Example 3:

[0063] The difference between this embodiment and the previous embodiments lies in the structure of the grass-pressing disc 203. Specifically, refer to... Figure 6 and Figure 7 In this embodiment, multiple pusher plates 9 move in the grass pressing disc 203. The pusher plates 9 are square-shaped, and the number and position of the pusher plates 9 correspond one-to-one with the receiving opening 4.

[0064] Reference Figure 7Specifically, the surface of the pusher plate 9 is parallel to the surface of the pressing disc 203. The length of the pusher plate 9 extends radially along the pressing disc 203, and the width of the pusher plate 9 is the same as the width of the receiving opening 4 near the center of the pressing disc 203. The pusher plate 9 moves along its own length within the pressing disc 203, and the cavity in the pressing disc 203 for the pusher plate 9 to move is connected to the corresponding receiving opening 4. This allows the end of the pusher plate 9 away from the center of the pressing disc 203 to move completely back into the pressing disc 203, or to move away from the center of the pressing disc 203 and extend into the corresponding receiving opening 4, thereby pushing out the hay in the receiving opening 4. To improve the ease of assembling the pusher plate 9, the pressing disc 203 is composed of two halves joined together.

[0065] To adjust the position of the pusher plate 9, an abutment rod 10 is fixed to one end of the pusher plate 9 near the center of the pressing disc 203. An adjusting member 11 is fixedly connected to the connecting frame 201, with its outer wall providing abutment against the abutment rod 10. The adjusting member 11 is sleeved on the rotating shaft 3. During the rotation of the pressing disc 203, the abutment rod 10 is always magnetically attracted to the outer wall of the adjusting member 11.

[0066] One end of the abutment rod 10 is fixed to the pusher plate 9, and the other end of the abutment rod 10 extends to the outside of the pressing plate 203 along the direction perpendicular to the plate surface of the pressing plate 203. An adjustment groove 16 is provided on the pressing plate 203 for the abutment rod 10 to move radially along the pressing plate 203.

[0067] Reference Figure 7 The adjusting member 11 includes a first adjusting section 111, a first transition section 112, a second adjusting section 113 and a second transition section 114 that are integrally formed and connected in sequence along the rotation axis 3. The first adjusting section 111 is connected to the second transition section 114 so that the adjusting member 11 forms a closed ring.

[0068] The first adjustment section 111 is an arc shape coaxial with the rotating shaft 3, and the first adjustment section 111 is simultaneously opposite to the lower middle, middle and upper parts of the grass pressing disc 203. When the receiving port 4 on the grass pressing disc 203 is located outside the sand, the abutment rod 10 is magnetically attracted to the outer peripheral wall of the first adjustment section 111. At this time, the pusher plate 9 corresponding to the receiving port 4 does not extend into the receiving port 4 but is stored in the grass pressing disc 203, so that the receiving port 4 of the grass pressing disc 203 can be inserted and receive the grass.

[0069] The second adjusting section 113 is an arc shape coaxial with the rotating shaft 3. The second adjusting section 113 is opposite to the lower part of the tamp disc 203, and the outer diameter of the second adjusting section 113 is larger than the outer diameter of the first adjusting section 111. When the receiving port 4 on the tamp disc 203 is close to or located at the bottom of the tamp disc 203, the abutment rod 10 is magnetically attracted to the outer wall of the second adjusting section 113. At this time, the pusher plate 9 corresponding to the receiving port 4 extends into the receiving port 4 and moves to be close to the outer peripheral wall of the tamp disc 203, thereby assisting in pushing the grass in the receiving port 4 into the sand and assisting in the discharge of grass on the tamp disc 203.

[0070] The first transition section 112 is used to connect one end of the first adjustment section 111 and one end of the second adjustment section 113. The second transition section 114 is used to connect the other end of the first adjustment section 111 and the other end of the second adjustment section 113. The distance from the outer wall of the first transition section 112 and the second transition section 114 to the axis of the rotation shaft 3 gradually increases along the circumference of the rotation shaft 3 from the first adjustment section 111 towards the second adjustment section 113, so that the first transition section 112 and the second transition section 114 are both used to smoothly transition and connect the outer wall of the first adjustment section 111 and the outer wall of the second adjustment section 113.

[0071] Reference Figure 6 and Figure 7 When the receiving opening 4 on the tamp disc 203 enters the sand, the corresponding abutment rod 10 slides from the outer wall of the first adjusting section 111 to the outer wall of the first transition section 112. When the receiving opening 4 on the tamp disc 203 leaves its lowest position, the corresponding abutment rod 10 slides from the outer wall of the second adjusting section 113 to the outer wall of the second transition section 114. When the receiving opening 4 on the tamp disc 203 leaves the sand, the corresponding abutment rod 10 slides from the outer wall of the second transition section 114 to the outer wall of the first adjusting section 111. Thus, during the rolling of the tamp disc 203 on the sand, the abutment rod 10 sequentially and cyclically abuts against the outer walls of the first adjusting section 111, the first transition section 112, the second adjusting section 113, and the second transition section 114, thereby assisting in pushing the fodder in the sand.

[0072] Reference Figure 7 Furthermore, an abutment ring 12 is detachably connected to the outer wall of the first adjusting section 111. The abutment ring 12 is arc-shaped, and its inner diameter is the same as the outer diameter of the first adjusting section 111, while its outer diameter is smaller than the outer diameter of the second adjusting section 113. The central angle of the abutment ring 12 is also the same as the central angle of the first adjusting section 111. The outer wall of the first adjusting section 111 has at least two bolt holes, and the abutment ring 12 has countersunk holes that correspond one-to-one with the bolt holes. The abutment ring 12 is coaxially connected to the first adjusting section 111 by countersunk bolts. The shank of the countersunk bolt is threaded through the countersunk hole into the bolt hole, and the head of the countersunk bolt abuts into the countersunk hole.

[0073] After the abutment ring 12 is installed into the first adjustment section 111, the two ends of the abutment ring 12 that are far apart from each other abut against the outer walls of the first transition section 112 and the second transition section 114, respectively, so that the outer wall of the abutment ring 12 is connected to the outer walls of the first transition section 112 and the second transition section 114. Thus, when the abutment rod 10 moves to the original position of the first adjustment section 111, the abutment rod 10 is magnetically attracted to the outer wall of the abutment ring 12. Since the outer diameter of the abutment ring 12 is larger than the outer diameter of the first adjustment section 111, the end of the pusher plate 9 that is far away from the abutment rod 10 is pushed into the receiving opening 4, reducing the size of the receiving opening 4 and thus reducing the amount of grass entering the receiving opening 4.

[0074] There are multiple abutment rings 12, each with a different outer diameter. For different terrains and wind speed adjustment components 11, a suitable abutment ring 12 can be selected and installed on the first adjustment section 111, or the abutment ring 12 can be removed from the first adjustment section 111 to adjust the size of the receiving opening 4, thereby adjusting the amount of grass inserted into the sand as needed.

[0075] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
