Technical Field

[0001] The present application relates to the technical field of sand management machinery, and in particular to a crawler-type grass pressing and sand covering integrated machine. Background Art

[0003] The grass pressing and sand covering machine is a device that assists in inserting grass into the sand. It usually has a rotating pressing wheel, which is used to press the middle of the grass laid on the sand into the sand during the movement of the machine, so as to achieve a close combination of the grass and the sand and form a sand barrier. However, the grass pressing operation usually requires manual or auxiliary equipment to pre-lay the grass, and then use the grass pressing and sand covering machine to press the grass, which increases the number of processes and reduces the overall operation efficiency. Summary of the invention

[0004] In order to improve the overall efficiency of grass compacting, the present application provides a crawler-type grass compacting and sand covering machine.

[0005] The present application provides a crawler-type grass pressing and sand covering integrated machine, which adopts the following technical solution: A crawler-type grass pressing and sand covering integrated machine comprises: 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 comprises A connecting frame connected to the pulling mechanism; A walking wheel, rotatably connected to the connecting frame via a rotating shaft; A grass pressing disc is connected to the rotating shaft to be coaxially arranged with the running wheel and rotate together with the running wheel, and the outer diameter of the grass pressing disc is larger than the outer diameter of the running wheel. The outer circumference of the grass pressing disc is evenly spaced along its circumference to form a plurality of receiving openings for grass to enter; and A feeding hopper is installed on the connecting frame, and is formed with a feeding cavity with an upward opening, and has a clearance port for the upper part of the grass pressing disc to enter the feeding cavity, and also has a discharge port connected with the clearance port. The discharge port is used to move the grass in the receiving port out of the feeding hopper from the discharge port when the grass pressing disc rotates.

[0006] By adopting the above technical solution, the grass is fed into the hopper so that the grass can fall into the receiving opening of the grass pressing disc. When the pulling mechanism drives the grass pressing mechanism to move, the walking wheel rolls on the sand to drive the grass pressing disc to roll synchronously, thereby bringing the grass on the grass pressing disc into and out of the hopper and inserting it into the sand, so as to realize the simultaneous laying of grass and pressing of grass, thereby improving the continuity of operation and the overall operation efficiency.

[0014] Optionally, the grass pressing mechanism further includes a scraper plate, which is fixed in the grass pressing disc and opposite to the discharge port, and the scraper plate abuts against an outer peripheral wall of the grass pressing disc located in the feeding cavity.

[0015] By adopting the above technical solution, the scraper plate can scrape off the grass outside the receiving opening of the grass pressing disc, thereby improving the uniformity of the grass distributed at intervals on the grass pressing disc, and further improving the uniformity of the formed grass and sand barrier.

[0016] Optionally, the grass pressing mechanism also includes a material blocking cover, one end of the material blocking cover is connected to the scraper plate, the other end of the material blocking cover extends out of the feed hopper from the discharge port, the material blocking cover extends circumferentially along the grass pressing disc and is close to the outer periphery of the forward end of the grass pressing disc, and the bottom of the material blocking cover is close to the bottom of the walking wheel.

[0017] By adopting the above technical solution, the material blocking cover prevents the grass from falling off the grass pressing disc easily when the grass pressing disc brings the grass out.

[0018] Optionally, a material pushing piece corresponding to the accommodating opening is provided in the grass pressing disc and moves radially along the grass pressing disc, and an end of the material pushing piece close to the rotating shaft is connected to an abutment rod extending to the outside of the grass pressing disc; The connecting frame is connected to an adjusting member enclosing the rotating shaft, and the adjusting member includes a first adjusting section, a first transition section, a second adjusting section and a second transition section in sequence along the circumference of the rotating shaft; the outer peripheral walls of the first adjusting section and the second adjusting section extend in directions coaxial with the rotating shaft, and the outer diameter of the first adjusting section is smaller than the outer diameter 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 two ends of the first adjusting section that are far away from each other; 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; When the grass pressing disc rotates, the abutment rod is magnetically attracted to the outer peripheral wall of the first adjustment section, the first transition section, the second adjustment section and the second transition section in a circular manner, and when the receiving opening on the grass pressing disc is located below the bottom position of the pressing wheel, the abutment rod corresponding to the receiving opening abuts against the first transition section, the second adjustment section and the second transition section in sequence; When the abutment rod abuts against the outer peripheral wall of the first adjustment section, the adjustment plate is retracted into the grass pressing disc; when the abutment rod abuts against the outer peripheral wall of the second adjustment section, the adjustment plate extends into the accommodating port, and the end of the adjustment plate away from the abutment rod approaches the outer peripheral wall of the grass pressing disc.

[0019] By adopting the above technical solution, the coordinated design of the pushing piece, the abutment rod and the adjusting piece realizes the dynamic adjustment of the grass in the receiving opening, so that the grass can enter the sand evenly and quantitatively.

DETAILED DESCRIPTION

[0025] The following is combined with Figure 1-7This application is described in further detail.

[0026] Embodiment 1: The present application embodiment discloses a crawler-type grass pressing and sand covering integrated machine. Figure 1 The grass pressing and sand covering machine comprises 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, and the pulling mechanism 1 drives the grass pressing mechanism 2 to move forward on the sand to bring and press the grass into the sand. The lifting mechanism 8 is installed between the pulling mechanism 1 and the grass pressing mechanism 2 to be able to drive the grass pressing mechanism 2 to rotate relative to the pulling mechanism 1 to a use state and a storage state.

[0027] Among them, for the pulling mechanism 1, the pulling mechanism 1 includes a tractor 101 and a grass placing platform 102. The tractor 101 is an existing crawler tractor 101, which is used to provide power for the entire machine to move forward on the sand. The grass placing platform 102 is in the shape of a square plate and is fixed on the body of the tractor 101, and the grass placing platform 102 plate surface extends horizontally. The operator can sit on the grass placing platform 102, and the grass placing platform 102 is also used to place grass that needs to be inserted into the sand.

[0028] Reference Figure 1 and Figure 2 As for the grass pressing mechanism 2, the grass pressing mechanism 2 has two groups, and the two groups of grass pressing mechanisms 2 are arranged horizontally along the vertical tractor 101 walking direction and connected to the grass placing platform 102. Each group of grass pressing mechanism 2 includes a connecting frame 201, a walking wheel 202, a grass pressing disc 203, a hopper 204 and a scraper plate 205.

[0029] The connecting frame 201 is in the shape of a hollow frame, and one end of the connecting frame 201 is hinged to the end of the grass placing platform 102 away from the advancing direction of the tractor 101. The bottom of the connecting frame 201 is rotatably connected to a rotating shaft 3 through a bearing seat (not shown in the figure), and the axial direction of the rotating shaft 3 is parallel to the distribution direction of the two groups of grass pressing mechanisms 2. One end of the rotating shaft 3 extends out of the side of the connecting frame 201 in the direction away from the other group of grass pressing mechanisms 2 and is fixed to the walking wheel 202. At the same time, the walking wheel 202 is coaxially sleeved on the outer wall of the rotating shaft 3. The walking wheel 202 is a rubber tire with rough raised stripes on the surface so that it can walk on the sand.

[0030] Reference Figure 2The grass pressing disc 203 is disc-shaped, and the grass pressing disc 203 is also coaxially sleeved and fixed on the rotating shaft 3, so that the grass pressing disc 203 is coaxial with the rotating shaft 3, and the outer diameter of the grass pressing disc 203 is larger than the outer diameter of the running wheel 202, so that when the running wheel 202 rolls on the sand, the lower part of the grass pressing disc 203 is embedded in the sand, and the running wheel 202 drives the grass pressing disc 203 to rotate synchronously through the rotating shaft 3. It should be noted that the outer periphery of the grass pressing disc 203 is evenly spaced along its own circumference and provided with a plurality of receiving openings 4, and the receiving openings 4 are used for grass to be inserted, so that the grass can be brought into the sand when the grass pressing disc 203 rotates.

[0031] Reference Figure 1 and Figure 2 The feed hopper 204 is in a square box shape to form a feeding cavity 5 with an opening facing upward, and the bottom of the feed hopper 204 is fixed to the top of the connecting frame 201. A clearance port 6 and a discharge port 7 connected to the feeding cavity 5 are provided on the bottom of the feed hopper 204. The discharge hopper is located on the side of the feed hopper 204 close to the grass placing platform 102, and the discharge port 7 extends in a direction parallel to the axis of the grass pressing disc 203, and the extension length of the discharge port 7 is greater than the length of the grass. The clearance port 6 is connected to the side of the discharge port 7 away from the grass placing platform 102, and the length of the clearance port 6 extends in a direction perpendicular to the axis of the grass pressing disc 203 and away from the grass placing platform 102. The extension thickness of the clearance port 6 in a direction parallel to the axis of the grass pressing disc 203 is slightly greater than the thickness of the grass pressing disc 203.

[0032] The side of the top of the grass pressing disc 203 away from the grass placing platform 102 extends into the hopper 204 through the clearance opening 6, while the side of the top of the grass pressing disc 203 close to the grass placing platform 102 extends into the hopper 204 through the discharge opening 7, and the grass pressing disc 203 is located in the middle of the discharge opening 7.

[0033] Reference Figure 1 and Figure 3 The scraper plate 205 is in the shape of a square plate and is fixed in the feed hopper 204. Specifically, the scraper plate 205 is fixed to the inner walls of the feed hopper 204 on opposite sides parallel to the axis of the grass pressing disc 203, the scraper plate 205 extends vertically, and the scraper plate 205 is located above the discharge port 7. At the same time, the lower surface of the scraper plate 205 abuts against the outer peripheral wall of the grass pressing disc 203 to scrape the grass outside the receiving port 4 of the grass pressing disc 203.

[0034] When the grass pressing and sand covering machine is in use, the traction machine 101 drives the grass pressing mechanism 2 to move on the sand, and the connecting frame 201 rotates relative to the grass platform 102 under the gravity of the components in the grass pressing mechanism 2 until the walking wheel 202 abuts against the sand surface, and the lower part of the grass pressing disc 203 is inserted into the sand. The walking wheel 202 is subjected to the pulling force of the tractor 101 and rolls on the sand, driving the grass pressing disc 203 to roll forward in the sand. At the same time, the operator puts the grass on the grass placing platform 102 into the placing cavity 5 and applies downward pressure to press the grass toward the grass pressing disc 203. The middle part of the grass is subjected to downward pressure and its own gravity and enters the receiving port 4 of the grass pressing disc 203, so that the grass is gradually taken out from the discharge port 7 during the rotation of the grass pressing disc 203, and the middle part of the grass is inserted into the sand. When the grass pressing disc 203 is turned away from the sand, the grass is squeezed and rubbed by the sand and leaves the grass pressing disc 203 and is limited to the sand. Two operators can feed the feed hoppers 204 of the two groups of grass pressing mechanisms 2 at the same time, so that two parallel rows of grass sand barriers are formed at the same time when the tractor 101 is moving.

[0035] Reference Figure 1 and Figure 4 Furthermore, in order to facilitate the inspection and replacement of the grass pressing mechanism 2, the connecting frame 201 can be detachably connected to the grass placing platform 102. Specifically, two connecting seats 13 are installed at the rear of the grass placing platform 102 by bolts. The two connecting seats 13 are respectively close to the opposite sides of the grass placing platform 102, and a screw rod 14 is sleeved on the two connecting seats 13 at the same time, and is connected to the screw rod 14 by bolts. The screw rod 14 serves as a hinge rod for the connecting frame 201 to be hinged on the grass placing platform 102. The connecting frame 201 is rotatably sleeved on the screw rod 14 and can move along the axial direction of the screw rod 14. A nut 15 is threadedly sleeved on the screw rod 14, and each connecting frame 201 corresponds to two nuts 15, and the two nuts 15 are respectively abutted against the opposite sides of the connecting frame 201 to limit the upward movement of the connecting frame 201 along the axial direction of the screw rod 14 when the grass pressing mechanism 2 is in use.

[0036] When the grass pressing mechanism 2 needs to be removed, one of the connecting seats 13 is removed from the grass placing platform 102 and separated from the screw 14, and then the nut 15 and the connecting frame 201 are separated from the screw 14 in sequence to remove the grass pressing mechanism 2. In addition, by adjusting the position of the nut 15, the distance between the grass pressing discs 203 on the two grass pressing mechanisms 2 can be adjusted to improve the adaptability of the device.

[0037] Reference Figure 1 and Figure 4As for the lifting mechanism 8, 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 tractor 101, and the vertical rod 81 extends in an upward direction gradually approaching the feed hopper 204, and 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 rewinding and unwinding the rope member 82.

[0038] The rope pulling member 82 includes a main rope 821 and a branch rope 822. One end of the main rope 821 is wound on the winder 83, and the other end of the main rope 821 extends along the vertical pole 81 and passes around the 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 parts in the grass pressing mechanism 2 away from the grass placing platform 102. In this embodiment, there are four branch ropes 822, of which two branch ropes 822 have ends away from the main rope 821 connected to the connecting frame 201 and the feed hopper 204 in one group of grass pressing mechanisms 2, and the other two branch ropes 822 have ends away from the main rope 821 connected to the connecting frame 201 and the feed hopper 204 in another group of grass pressing mechanisms 2; in other embodiments, there can also be two branch ropes 822, and the two branch ropes 822 are respectively connected to the connecting frames 201 in the two groups of grass pressing mechanisms 2, or are respectively connected to the feed hoppers 204 in the two groups of grass pressing mechanisms 2.

[0039] When the grass pressing operation is performed on the sand, the main rope 821 and the branch rope 822 are both in a relaxed state, and the grass pressing mechanism 2 is in use at this time, and the rotation angle between the connecting frame 201 and the grass placing platform 102 can be adjusted automatically according to the ups and downs of the sand. After the grass pressing operation is completed, the main rope 821 is rolled up, so that the main rope 821 and the branch rope 822 are both stretched straight, and the main rope 821 and the branch rope 822 pull the connecting frame 201 to rotate upward relative to the grass placing platform 102, so as to drive the lowest point of each component in the grass pressing mechanism 2 to be higher than the lowest point of the sand surface and the tractor 101. At this time, the grass pressing mechanism 2 is in a storage state, and when the tractor 101 moves, the grass pressing mechanism 2 will not interfere with the sand surface or the ground.

[0040] The implementation principle of a crawler-type grass pressing and sand covering integrated machine in the embodiment of the present application is as follows: when the tractor 101 moves on the sand, it drives the walking wheel 202 and the grass pressing wheel to roll in the sand, puts grass into the feed hopper 204 and presses the grass down, and the grass enters the receiving port 4 of the grass pressing wheel. When the grass pressing wheel rolls, it brings the grass into and out of the feed hopper 204 and inserts it into the sand, so as to realize the synchronous feeding and insertion.

[0041] Embodiment 2: The difference between the embodiment of the present application and the embodiment 1 is that, referring to Fig. 5, the embodiment of the present application further includes a material blocking cover 206. The material blocking cover 206 is in the shape of an arc plate, and the inner diameter of the material blocking cover 206 is slightly larger than the outer diameter of the grass pressing disc 203. Specifically, the inner diameter of the material blocking cover 206 is 1cm-2cm larger than the outer diameter of the grass pressing disc 203, and 1cm is selected in the embodiment of the present application.

[0042] The upper end of the material blocking cover 206 is fixed to the bottom of the scraper plate 205, and the lower end of the material blocking cover 206 extends from the discharge port 7 to enter and exit the hopper 204. The lower end of the material blocking cover 206 is close to and higher than the bottom of the walking wheel 202, so that the material blocking cover 206 is not easy to contact the sand surface. At the same time, the material blocking cover 206 is coaxially arranged with the grass pressing disc 203 and is opposite to one side of the grass pressing disc 203 in the forward direction.

[0043] Therefore, when the grass pressing disc 203 brings the grass into and out of the hopper 204 through the receiving port 4, the grass is opposite to the material blocking cover 206 during the downward movement, so that it is not easily affected by wind, gravity, etc. and leaves the grass pressing disc 203, thereby improving the stability of the grass on the grass pressing disc 203 when the grass pressing disc 203 rotates.

[0044] Embodiment three: The difference between the embodiment of the present application and the above-mentioned embodiments is that the structure of the grass pressing plate 203 in the present embodiment is different. Figure 6 and Figure 7 In this embodiment, a plurality of push pieces 9 are movable in the grass pressing disc 203 . The push pieces 9 are in the shape of square pieces, and the number and positions of the push pieces 9 correspond one-to-one to the accommodating openings 4 .

[0045] Reference Figure 7 Specifically, the surface of the push piece 9 is parallel to the plate surface of the grass pressing disc 203, the length direction of the push piece 9 extends radially along the grass pressing disc 203, the width of the push piece 9 is consistent with the width of the side of the receiving port 4 close to the center of the grass pressing disc 203, the push piece 9 moves in the grass pressing disc 203 along its own length direction, and the cavity in the grass pressing disc 203 for the push piece 9 to move is connected with the receiving port 4 corresponding to the push piece 9, so that the end of the push piece 9 away from the center of the grass pressing disc 203 can move to be completely recovered into the grass pressing disc 203, or move away from the center of the grass pressing disc 203 to extend into the corresponding receiving port 4, so as to push out the grass in the receiving port 4. In order to improve the convenience of assembling the push piece 9, the grass pressing disc 203 is spliced ​​in half.

[0046] In order to adjust the position of the push piece 9, an abutting rod 10 is fixed to one end of the push piece 9 near the center of the grass pressing disc 203, and an adjusting member 11 whose outer wall is fixedly connected to the connecting frame 201 for the abutting rod 10 to abut against is sleeved on the rotating shaft 3. During the rotation of the grass pressing disc 203, the abutting rod 10 is always magnetically attracted to the outer wall of the adjusting member 11.

[0047] One end of the abutment rod 10 is fixed on the pushing piece 9, and the other end of the abutment rod 10 extends to the outside of the grass pressing disc 203 along a direction perpendicular to the plate surface of the grass pressing disc 203, and the grass pressing disc 203 is provided with an adjustment groove 16 for the abutment rod 10 to move radially along the grass pressing disc 203.

[0048] 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 which are integrally formed and connected in sequence along the circumference of the rotating shaft 3. The first adjusting section 111 is also connected to the second transition section 114 so that the adjusting member 11 forms a closed ring.

[0049] Among them, the first adjustment section 111 is in the shape of an arc coaxial with the rotating shaft 3, and the first adjustment section 111 is simultaneously opposite to the middle and lower part, the middle part and the upper part of the grass pressing disc 203. When the receiving opening 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 pushing piece 9 corresponding to the receiving opening 4 does not extend into the receiving opening 4 but is received in the grass pressing disc 203, so that the receiving opening 4 of the grass pressing disc 203 can be stuck in and receive grass.

[0050] The second adjustment section 113 is in an arc shape coaxial with the rotating shaft 3, and is opposite to the lower position of the grass pressing disc 203, and the outer diameter of the second adjustment section 113 is greater than the outer diameter of the first adjustment section 111. When the receiving port 4 on the grass pressing disc 203 is close to or located at the bottom of the grass pressing disc 203, the abutment rod 10 is magnetically attracted to the outer wall of the second adjustment section 113, and the pushing piece 9 corresponding to the receiving port 4 is extended into the receiving port 4 and moved to the outer peripheral wall close to the grass pressing disc 203, thereby assisting in pushing the grass in the receiving port 4 into the sand and assisting in the discharge of the grass on the grass pressing disc 203.

[0051] 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, and 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 distances from the outer walls of the first transition section 112 and the second transition section 114 to the axis of the rotating shaft 3 gradually increase along the circumference of the rotating shaft 3 from the first adjustment section 111 to the direction approaching the second adjustment section 113, so that the first transition section 112 and the second transition section 114 are 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.

[0052] Reference Figure 6 and Figure 7When the receiving opening 4 on the grass pressing disc 203 enters the sand, the abutment rod 10 corresponding to the receiving opening 4 slides from the outer wall of the first adjustment section 111 to the outer wall of the first transition section 112. When the receiving opening 4 on the grass pressing disc 203 leaves the lowest position of the grass pressing disc 203, the abutment rod 10 corresponding to the receiving opening 4 slides from the outer wall of the second adjustment section 113 to the outer wall of the second transition section 114. When the receiving opening 4 on the grass pressing disc 203 leaves the sand, the abutment rod 10 corresponding to the receiving opening 4 slides from the outer wall of the second transition section 114 to the outer wall of the first adjustment section 111. Thus, during the rolling process of the grass pressing disc 203 on the sand, the abutment rod 10 cyclically abuts against the outer walls of the first adjustment section 111, the first transition section 112, the second adjustment section 113 and the second transition section 114 in turn, thereby realizing auxiliary pushing of grass in the sand.

[0053] Reference Figure 7 Furthermore, a resistance ring 12 is detachably connected to the outer wall of the first adjustment section 111. The resistance ring 12 is in an arc shape, and the inner diameter of the resistance ring 12 is consistent with the outer diameter of the first adjustment section 111, and the outer diameter of the resistance ring 12 is smaller than the outer diameter of the second adjustment section 113. The central angle of the resistance ring 12 is also consistent with the central angle of the first adjustment section 111. There are at least two bolt holes on the outer wall of the first adjustment section 111, and the resistance ring 12 has countersunk holes corresponding to the bolt holes one by one. The resistance ring 12 is coaxially connected to the first adjustment section 111 through a countersunk bolt, and the rod of the countersunk bolt is threaded into the bolt hole through the countersunk hole, and the head of the countersunk bolt is pressed into the countersunk hole.

[0054] After the abutment ring 12 is installed to the first adjustment section 111, the two ends of the abutment ring 12 that are away from each other respectively abut against the outer walls of the first transition section 112 and the second transition section 114, so that the outer wall of the abutment ring 12 is connected with the outer wall of the first transition section 112 and the outer wall of the second transition section 114. Therefore, 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 greater than the outer diameter of the first adjustment section 111, the end of the pusher 9 away from the abutment rod 10 is pushed into the receiving port 4, so that the size of the receiving port 4 is reduced, so that the amount of forage entering the receiving port 4 is reduced.

[0055] There are multiple interference rings 12, and the outer diameters of the interference rings 12 are different. In different terrains and wind speed adjustment parts 11, a suitable interference ring 12 is selected and installed on the first adjustment section 111, or the interference ring 12 is removed from the first adjustment section 111 to be able to adjust the size of the accommodating port 4, so that the amount of grass inserted into the sand can be adjusted as needed.

[0056] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
