Description

Technical Field

[0001] This application belongs to the field of agricultural machinery technology, and specifically relates to a harrowing machine for leveling pasture. Background Technology

[0002] Pasture leveling is one of the core aspects of pasture planting and management. By uniformly cutting the pasture, ventilation and light penetration can be effectively improved, pasture tillering and regeneration can be promoted, and the yield and quality of pasture can be increased. This is of great significance for maintaining the ecological balance of the grassland and ensuring the supply of feed for animal husbandry.

[0003] Currently, the main technical problems with raking machines used for pasture leveling on the market are as follows: most of the equipment uses a fixed structure for mowing, and the radial position of the blades cannot be flexibly adjusted. This makes it difficult to adapt to the height requirements of different forage varieties (such as tall ryegrass and dwarf clover) or different growth stages of the same variety (such as the greening stage and the maturity stage). This can easily lead to inconsistent mowing depth. If the mowing is too shallow, it may not be able to level the grass effectively, while if it is too deep, it may damage the grass roots and affect regeneration, thus reducing the leveling effect of the pasture.

[0004] Therefore, developing a pasture leveling harrow that can flexibly adjust the mowing height to improve the efficiency and quality of pasture leveling is a technical problem that urgently needs to be solved in this field. Utility Model Content

[0005] This application provides a pasture leveling harrow that can flexibly adjust the mowing height, in order to solve the problems of existing pasture leveling harrows in terms of adjusting the mowing height and ease of operation.

[0006] To achieve the above objectives, this application provides a pasture leveling harrow, including a vehicle body, a push handle fixedly installed at one end of the vehicle body, and a mowing chamber installed at the other end. A mowing mechanism is installed inside the mowing chamber, and the mowing mechanism is connected to a motor through a pulley assembly.

[0007] The mowing mechanism includes a first blade plate and a second blade plate, which are rotatably disposed on opposite sides within the mowing chamber. The second blade plate is connected to the first blade plate via a rotating shaft, the end of which near the second blade plate is connected to the pulley assembly. The first blade plate has multiple adjusting grooves extending around its circumference, and a limiting rod is slidably disposed within each adjusting groove. The second blade plate has corresponding limiting grooves extending around its circumference, and a mounting seat is slidably disposed within each limiting groove. A blade is fixedly disposed between the limiting rod and the mounting seat. The first blade plate has a partition ring chamber, and a diameter adjustment assembly is installed within the partition ring chamber. The diameter adjustment assembly is connected to the multiple limiting rods.

[0008] In one embodiment, the diameter adjustment assembly includes a plurality of fixed grooves corresponding to the adjustment grooves on the isolation ring chamber and an adjustment disc rotatably disposed within the isolation ring chamber. The end of the slide rod away from the blade is slidably disposed within the fixed grooves. A plurality of limiting ring grooves are provided through the adjustment disc. A limiting boss is slidably disposed within the limiting ring grooves. The limiting boss is also fixedly connected to the end of the limiting slide rod near the fixed groove.

[0009] In one embodiment, an adjustment component is also included. The adjustment component includes a mounting ring, which is rotatably mounted on the side wall of the mowing chamber and fixedly connected to the partition ring chamber. A second limiting shaft is fixedly mounted at the end of the mounting ring near the first blade plate. A first limiting shaft is fixedly mounted on the adjustment disc. An adjustment shaft is slidably mounted within the first and second limiting shafts. A knob is fixedly mounted at the end of the adjustment shaft away from the adjustment disc.

[0010] In one embodiment, a compression spring is provided between the knob and the second limiting shaft.

[0011] In one embodiment, a protrusion is provided on the outside of the adjusting shaft, and grooves are provided inside the first limiting shaft and the second limiting shaft.

[0012] In one embodiment, two guide wheel assemblies are symmetrically arranged at the bottom of the mowing bin.

[0013] Compared with the prior art, the beneficial effects of this application are:

[0014] 1. Adjustable radial position of the blade to adapt to different grass height requirements: Through the adjustment plate, fixed slide groove and limit slide rod in the diameter adjustment component, the radial position of the blade can be flexibly adjusted to achieve precise cutting of grass at different growth heights, ensuring uniform cutting effect and significantly improving the efficiency and quality of pasture leveling operations.

[0015] 2. Convenient adjustment and reliable locking: The adjustment components (mounting ring, adjustment shaft, limit shaft, compression spring and knob) are ingeniously designed. Pressing the knob will release the lock, and after rotation adjustment, releasing the knob will automatically reset and lock through the limit shaft. This effectively prevents changes in mowing depth caused by accidental rotation of the adjustment disc during operation, and improves the reliability and safety of equipment operation.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are also within the scope of protection of this application.

[0026] See Figures 1 to 7 As shown, the pasture leveling harrow provided in this application includes a vehicle body 1, with a push handle 2 fixedly installed at one end of the vehicle body 1 and a mowing chamber 3 installed at the other end. A mowing mechanism 5 is installed inside the mowing chamber 3, and the mowing mechanism 5 is connected to a motor 6 via a pulley assembly 7. Optionally, the motor 6 is fixedly installed on the top of the vehicle body 1.

[0027] When using this equipment to level pasture, first start the motor 6 to drive the mowing mechanism 5 to rotate through the pulley assembly 7. The mowing mechanism 5 quickly cuts the pasture. At the same time, the operator holds the push handle 2 to push the vehicle body 1 forward, so that the mowing mechanism 5 continuously and evenly cuts the pasture, thereby achieving rapid leveling of the pasture.

[0028] The mowing mechanism 5 includes a first blade plate 51 and a second blade plate 52, which are rotatably disposed on opposite sides of the mowing chamber 3. The second blade plate 52 is connected to the first blade plate 51 by a rotating shaft 59, which is connected to a pulley assembly 7 at one end near the second blade plate 52. The first blade plate 51 has multiple adjusting grooves 54 extending around its circumference, and a limiting rod 573 is slidably disposed within each adjusting groove 54. The second blade plate 52 has a limiting groove 523 extending around its circumference corresponding to the adjusting grooves 54, and a mounting slide 524 is slidably disposed within each limiting groove 523. A blade 53 is fixedly disposed between the limiting rod 573 and the mounting slide 524. The first blade plate 51 has a partition ring chamber 56, and a diameter adjustment assembly 57 is installed within the partition ring chamber 56. The diameter adjustment assembly 57 is connected to the multiple limiting rods 573.

[0029] In this embodiment, the motor 6 drives the pulley assembly 7 to rotate the shaft 59, which in turn drives the second blade plate 52 to rotate synchronously with the first blade plate 51, ensuring that the two blade plates work together. The two ends of the blade 53 are connected to the mounting slide 524 through the limiting slide rod 573, ensuring that the blade 53 remains stable during high-speed rotation and preventing the blade 53 from becoming loose or shifting due to vibration, which would affect the mowing effect.

[0030] When leveling pasture, since the growth status of pasture in different pasture areas is not the same, before mowing, the operator observes the height of the pasture and, based on the actual situation, pushes the limiting slide bar 573 to move within the adjusting groove 54 through the diameter adjustment component 57. The two ends of the blade 53 are connected to the mounting slide 524 through the limiting slide bar 573, thereby stabilizing the radial position of the blade 53 along the blade plate. This ensures that the mowing mechanism 5 can adapt to pasture of different heights, achieves cutting for different pasture heights, ensures uniform mowing effect, and improves the overall efficiency and quality of pasture leveling operations.

[0031] Optionally, the diameter adjustment assembly 57 includes a plurality of fixed slide grooves 572 corresponding to the adjustment slide groove 54 on the partition ring chamber 56 and an adjustment disc 571 rotatably disposed in the partition ring chamber 56. The end of the limiting slide rod 573 away from the blade 53 is slidably disposed in the fixed slide groove 572. A plurality of limiting ring grooves 574 are provided through the adjustment disc 571. A limiting boss 575 is slidably disposed in the limiting ring groove 574. The limiting boss 575 is also fixedly connected to the end of the limiting slide rod 573 near the fixed slide groove 572.

[0032] During the leveling of pasture, the drive adjustment plate 571 is rotated. During the rotation, the adjustment plate 571 drives the limit bosses 575 to slide within the limit ring grooves 574. Then, the other end of the limit bosses 575 pushes the limit slide rods 573 to move within the fixed slide grooves 572, further adjusting the radial position of the blades 53.

[0033] After the blade 53 is adjusted, the adjustment component 8 is fixed back to the partition ring chamber 56, and the adjustment disc 571 is further locked to prevent the adjustment disc 571 from deflecting during the cutting process of the blade 53, which would cause the cutting depth to change and affect the leveling effect.

[0034] Optionally, an adjustment assembly 8 is also included. The adjustment assembly 8 includes a mounting ring 81, which is rotatably mounted on the side wall of the mowing chamber 3 and fixedly connected to the partition ring chamber 56. A second limiting shaft 85 is fixedly mounted on the end of the mounting ring 81 near the first blade plate 51. A first limiting shaft 83 is fixedly mounted on the adjustment disc 571. An adjustment shaft 82 is slidably mounted within the first limiting shaft 83 and the second limiting shaft 85. A knob 55 is fixedly mounted on the end of the adjustment shaft 82 away from the adjustment disc 571. A compression spring 84 is provided between the knob 55 and the second limiting shaft 85.

[0035] In this embodiment, the adjustment assembly 8 drives the adjustment disk 571 to rotate. Specifically, when the machine is stopped and the height of the blade 53 for cutting hay needs to be adjusted, the operator first presses the knob 55 towards the first blade plate 51. During the pressing of the knob 55, the adjustment shaft 82 is driven to slide towards the first blade plate 51 against the elastic force of the compression spring 84. As the adjustment shaft 82 slides towards the first blade plate 51, it disengages from the limit of the second limit shaft 85, causing the adjustment shaft 82 to... The second limiting shaft 85 and the mounting ring 81 can rotate freely. At this time, the first limiting shaft 83 and the adjusting shaft 82 are still engaged. The operator continues to rotate the knob 55. During the rotation of the knob 55, the adjusting shaft 82 is driven to rotate. The adjusting shaft 82 drives the first limiting shaft 83 to rotate. In turn, the first limiting shaft 83 drives the adjusting disk 571 to rotate. During the rotation of the adjusting disk 571, the limiting boss 575 slides in the limiting ring groove 574, pushing the limiting slide rod 573 to move stably, ensuring the radial position adjustment of the blade 53.

[0036] After the radial position of the blade 53 is adjusted, the operator releases the knob 55. The released knob 55 automatically resets under the action of the compression spring 84. At the same time, the knob 55 drives the adjustment shaft 82 to reset, so that the adjustment shaft 82 re-engages with the second limit shaft 85. Thus, the fixing action of the mounting ring 81 locks the adjustment plate 571 to rotate, ensuring that the height of the blade 53 remains stable during the mowing process. This avoids changes in mowing depth caused by accidental rotation of the adjustment plate 571, further improving the reliability and safety of the mowing operation, and ensuring the flatness of the pasture and the efficiency of mowing.

[0037] It should be noted that a protrusion is provided on the outer side of the adjusting shaft 82, and grooves are provided in the first limiting shaft 83 and the second limiting shaft 85. When the protrusion is slid into the groove, the adjusting shaft 82 is engaged with the first limiting shaft 83 and the second limiting shaft 85.

[0038] Optionally, two guide wheel assemblies 4 are symmetrically arranged at the bottom of the mowing chamber 3. When the operator pushes the vehicle body 1 to move, the guide wheel assembly 4 can effectively support the mowing chamber 3, improve the stability and maneuverability of the mower, and at the same time facilitate the operator to control the direction of travel of the vehicle body 1.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
