A crawler-type grass roller

Abstract

This utility model belongs to the technical field of hay pressing vehicles, and in particular, a tracked hay pressing vehicle, including a frame. The outer surface of the frame is provided with a driving device, which includes track wheels. The track wheels drive the frame to move by rolling the track chain. By setting a hay pressing device, the hay mat is flattened. The outer surface of the rotating gear has multiple arc-shaped grooves. When the electromagnetic ring is energized, the driving gear meshes with the rotating gear, thereby driving the rotating gear to rotate. The rotating gear drives the hay pressing blades, which are slidably connected to the inner wall of the arc-shaped grooves, to rotate synchronously. However, because the turntable is slidably inserted into the hay pressing blades, it limits their movement, so that the diameter of the circle formed by the multiple hay pressing blades can be adjusted to control the hay pressing depth.

Description

Technical Field

[0001] This utility model relates to the field of hay press vehicle technology, and in particular to a tracked hay press vehicle. Background Technology

[0002] The Three-North Shelterbelt Project is a major ecological project implemented by China to address the increasingly serious problems of desertification and soil erosion. The goal of the project is to establish an ecological barrier to prevent the expansion of desertification and gradually restore the ecological environment. In this process, straw mats and sand barriers have become very important means of preventing and controlling desertification.

[0003] In the existing technology, there are many sand dunes and semi-sand dunes. Traditional tire-type grass trimmers are not only prone to getting stuck in the sand, but also have a very limited working range. However, since the diameter of the grass trimmer blade is fixed, it is difficult to achieve precise control of the depth, resulting in grass trimming that is too shallow and the grass mat is not firmly fixed, or too deep, causing unnecessary soil disturbance and affecting the ecological environment. Therefore, a tracked grass trimmer is proposed to solve the above-mentioned problems. Utility Model Content

[0004] In order to solve the technical problems of existing technologies, such as traditional tire-type hay bale rollers not only easily getting stuck in sand, but also having a very limited working range, and because the diameter of the hay bale roller blades is fixed, it is difficult to achieve precise control of the depth, resulting in hay bale rollers being too shallow and the hay curtains not being fixed firmly, or too deep, which affects the ecological environment, this application provides a tracked hay bale roller.

[0005] The present invention discloses a tracked hay press, comprising a frame, wherein a drive device is provided on the outer surface of the frame, the drive device comprising track wheels, and the track wheels driving the frame to move by the rolling of track chains.

[0006] The outer surface of the frame is provided with a grass-pressing device, which includes a grass-pressing blade. The rotation of the grass-pressing blade flattens the grass curtain.

[0007] Preferably, the driving device further includes a drive motor, which is fixedly installed on the inner side wall of the frame. A drive rod is fixedly installed on the output shaft of the drive motor, and one end of the drive rod is rotatably connected to the inner side wall of the frame through a bearing.

[0008] The above technical solution involves fixing the drive motor to the frame and the drive rod to the drive motor, thereby driving the drive rod to rotate. This facilitates increased power output and maintains operational stability. The drive rod is rotatably connected to the frame via bearings, ensuring that its rotation is not affected while it is fixed, thus guaranteeing rotational stability.

[0009] Preferably, the inner wall of the groove of the front drive wheel of the track wheel is fixedly installed with the outer surface of the drive rod, and the inner side wall of the frame is rotatably connected to a rotating rod through a bearing. The outer surface of the rotating rod is fixedly installed with the inner wall of the groove of the rear drive wheel of the track wheel.

[0010] The above technical solution involves fixing the inner wall of the front drive wheel of the track wheel to the drive rod, thereby driving the front drive wheel to rotate and transmitting power to the track chain. The frame and the rotating rod are rotatably connected by bearings, fixing them without affecting their rotation. The rotating rod is fixedly installed to the rear drive wheel of the track wheel. When the track chain drives the rear drive wheel to rotate, it synchronously drives the rotating rod to rotate, so as to drive the drive gear that is slidably inserted with the rotating rod to rotate.

[0011] Preferably, the straw-pressing device further includes a turntable, one end of the support rod of the turntable is rotatably connected to the inner side wall of the frame, a movable motor is fixedly installed on the outer surface of the frame, the output shaft of the movable motor is fixedly installed to the other end of the support rod of the turntable, a rotating gear is rotatably connected to the outer surface of the support rod of the turntable, a fixed electromagnet is fixedly installed on the outer side of the turntable, and the inner side of the rotating gear is magnetically connected to the outer side of the fixed electromagnet through an adsorption component.

[0012] Through the above technical solution, one end of the turntable's support rod is rotatably connected to the frame, fixing it without affecting its rotation. The frame is fixedly installed to the mobile motor, which drives the turntable to rotate. The turntable is rotatably connected to the rotating gear, fixing it without affecting its rotation. The outer side of the turntable is fixedly installed to the fixed electromagnet, which is magnetically connected to the rotating gear via an adsorption component. The wire of the fixed electromagnet is connected to the power supply. When the fixed electromagnet is energized, the adsorption component fixes the rotating gear and the turntable together, allowing them to rotate synchronously while remaining relatively stationary. This ensures that the grass-pressing blades maintain a consistent diameter during operation, avoiding unnecessary adjustment deviations. When the fixed electromagnet is de-energized, the rotating gear can rotate independently of the turntable, thus desynchronizing the rotation of the turntable and the rotating gear.

[0013] Preferably, the outer surface of the rotating gear is provided with multiple arc-shaped grooves, the inner wall of the arc-shaped grooves is slidably connected to the pin surface of the grass-pressing knife, and the inner wall of the groove of the turntable is slidably inserted into the outer surface of the grass-pressing knife.

[0014] The above technical solution involves multiple arc-shaped grooves on the outer surface of the rotating gear. When the rotating gear rotates, it drives the grass-pressing blades, which are slidably connected to the inner wall of the arc-shaped grooves, to rotate synchronously. However, since the turntable is slidably inserted into the grass-pressing blades, it limits their movement, allowing the circular diameter formed by the multiple grass-pressing blades to be adjusted in order to control the grass-pressing depth.

[0015] Preferably, an electromagnetic ring is fixedly installed at one end of the rotating rod, a drive gear is rotatably connected to the outer surface of the rotating rod via a bearing, and the electromagnetic ring is electrically connected via a conductive slip ring.

[0016] The above technical solution involves fixing the rotating rod to the electromagnetic ring and driving its rotation. The rotating rod and the drive gear are connected by bearings, which fixes the rod without affecting its rotation, thus ensuring the stability of the rotation. The electromagnetic ring is electrically connected through a conductive slip ring, allowing the electromagnetic ring to maintain a continuous electrical connection with external equipment during rotation, avoiding interruption of the electrical connection caused by rotation.

[0017] Preferably, the inner surface of the drive gear is magnetically connected to the outer surface of the electromagnetic ring via an adsorption element, and the drive gear meshes with the rotating gear.

[0018] Through the above technical solution, the drive gear is magnetically connected to the electromagnetic ring through the adsorption component, and the electromagnetic ring is connected to the power supply through the conductive slip ring. When the electromagnetic ring is energized, the drive gear is fixed to it, and the two rotate synchronously. The drive gear meshes with the rotating gear, driving the rotating gear to rotate. Thus, the arc-shaped groove on the rotating gear drives the grass-pressing blades to move on the slidingly inserted turntable, adjusting the circular diameter formed by multiple grass-pressing blades.

[0019] The beneficial effects of this utility model are as follows: 1. By setting up a drive device, the frame is moved, the drive motor drives the drive rod to rotate, the inner wall of the front drive wheel of the track wheel is fixedly installed with the drive rod, driving the front drive wheel to rotate, and then transmitting power to the track chain. The rotating rod is fixedly installed with the rear drive wheel of the track wheel. When the track chain drives the rear drive wheel to rotate, it synchronously drives the rotating rod to rotate, so as to drive the drive gear that is slidably inserted with the rotating rod to rotate. This solves the technical problem in the existing technology that traditional tire-type grass compactors are not only easy to get stuck in the sand in many sand dunes and semi-sand dunes, but also have a particularly limited working range.

[0020] 2. By setting up a grass-pressing device, the grass mat is flattened. When the fixed electromagnet is energized, the rotating gear and the turntable are fixed together by the adsorption component, and the two can rotate synchronously. When the fixed electromagnet is de-energized, the rotating gear can rotate independently of the turntable, so that the rotation of the turntable and the rotating gear are no longer synchronized. The outer surface of the rotating gear has multiple arc-shaped grooves. The electromagnetic ring 6 is connected to the power supply through a conductive slip ring, and the drive gear is fixed to it. The two rotate synchronously. The drive gear meshes with the rotating gear, thereby driving the rotating gear to rotate. The rotating gear drives the grass-pressing blades that are slidably connected to the inner wall of the arc-shaped grooves to rotate synchronously. However, because the turntable and the grass-pressing blades are slidably inserted, they are limited and can only move. This allows the diameter of the circle formed by the multiple grass-pressing blades to be adjusted so as to control the grass-pressing depth. This solves the technical problem in the existing technology that, due to the fixed diameter of the grass-pressing blades, it is difficult to achieve precise depth control, resulting in grass pressing that is too shallow and the grass mat is not firmly fixed, or too deep, resulting in unnecessary soil disturbance and affecting the ecological environment.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figures 1-8 A tracked hay bale vehicle includes a frame 1, and a drive device is provided on the outer surface of the frame 1. The drive device includes track wheels 3, and the track wheels 3 drive the frame 1 to move by rolling the track chain.

[0025] To drive the drive rod 21 to rotate, the drive device also includes a drive motor 2. The drive motor 2 is fixedly installed on the inner side wall of the frame 1. The output shaft of the drive motor 2 is fixedly installed with the drive rod 21. One end of the drive rod 21 is rotatably connected to the inner side wall of the frame 1 through a bearing. The drive motor 2 is fixedly installed to the frame 1, thus fixing it in place. The drive rod 21 is fixedly installed to the drive motor 2, which drives the drive rod 21 to rotate, thereby improving power output and maintaining working stability. The drive rod 21 is rotatably connected to the frame 1 through a bearing, which fixes it without affecting its rotation, thus ensuring rotational stability.

[0026] To drive the drive gear 61, which is slidably inserted into the rotating rod 31, the inner wall of the groove of the front drive wheel of the track wheel 3 is fixedly installed with the outer surface of the drive rod 21. The inner side wall of the frame 1 is rotatably connected to the rotating rod 31 through a bearing. The outer surface of the rotating rod 31 is fixedly installed with the inner wall of the groove of the rear drive wheel of the track wheel 3. The front drive wheel of the track wheel 3 is fixedly installed with the drive rod 21, which drives the front drive wheel to rotate, thereby transmitting power to the track chain. The frame 1 and the rotating rod 31 are rotatably connected through a bearing, which fixes them without affecting their rotation. The rotating rod 31 is fixedly installed with the rear drive wheel of the track wheel 3. When the track chain drives the rear drive wheel to rotate, it synchronously drives the rotating rod 31 to rotate, so as to drive the drive gear 61, which is slidably inserted into the rotating rod 31, to rotate.

[0027] By setting up a drive device, the frame 1 is moved, the drive motor 2 drives the drive rod 21 to rotate, the inner wall of the front drive wheel of the track wheel 3 is fixedly installed with the drive rod 21, driving the front drive wheel to rotate, and then transmitting power to the track chain. The rotating rod 31 is fixedly installed with the rear drive wheel of the track wheel 3. When the track chain drives the rear drive wheel to rotate, it synchronously drives the rotating rod 31 to rotate, so as to drive the drive gear 61 that is slidably inserted with the rotating rod 31 to rotate. This solves the technical problem in the prior art that in many sand dunes and semi-sand dunes, traditional tire-type grass-pressing vehicles are not only easy to get stuck in the sand, but also have a particularly limited working range.

[0028] In order to flatten the straw mat, a straw pressing device is provided on the outer surface of the frame 1. The straw pressing device includes a straw pressing blade 51, and the rotation of the straw pressing blade 51 flattens the straw mat.

[0029] To enable the rotating gear 41 to rotate independently of the turntable 4, the straw-pressing device also includes the turntable 4. One end of the support rod of the turntable 4 is rotatably connected to the inner wall of the frame 1. A moving motor 43 is fixedly installed on the outer surface of the frame 1. The output shaft of the moving motor 43 is fixedly installed to the other end of the support rod of the turntable 4. The rotating gear 41 is rotatably connected to the outer surface of the support rod of the turntable 4. A fixed electromagnet 42 is fixedly installed on the outer side of the turntable 4. The inner side of the rotating gear 41 is magnetically connected to the outer side of the fixed electromagnet 42 through an adsorption component. The support rod of the turntable 4 is rotatably connected to the frame 1, fixing it without affecting its rotation. The frame 1 is fixedly installed to the moving motor 43, fixing it in place. The other end of the support rod of the turntable 4 is fixed to the frame 1. The rotating gear 4 is fixedly installed at the end and drives the turntable 4 to rotate. The turntable 4 is rotatably connected to the rotating gear 41, and its rotation is not affected while it is fixed. The fixed electromagnet 42 is fixedly installed on the outer side of the turntable 4. The fixed electromagnet 42 and the rotating gear 41 are magnetically connected by an adsorption component. The wire of the fixed electromagnet 42 is connected to the power supply. When the fixed electromagnet 42 is energized, the rotating gear 41 and the turntable 4 are fixed together by the adsorption component. The two can rotate synchronously and are in a relatively stationary state to ensure that the grass-pressing blade 51 has a consistent diameter during operation and to avoid unnecessary adjustment deviations. When the fixed electromagnet 42 is de-energized, the rotating gear 41 can rotate independently of the turntable 4, so that the rotation of the turntable 4 and the rotating gear 41 are no longer synchronized.

[0030] To control the pressing depth, the outer surface of the rotating gear 41 is provided with multiple arc-shaped grooves 5. The inner wall of the arc-shaped grooves 5 is slidably connected to the pin surface of the pressing blade 51. The inner wall of the groove of the turntable 4 is slidably inserted into the outer surface of the pressing blade 51. As the rotating gear 41 rotates, it drives the pressing blade 51, which is slidably connected to the inner wall of the arc-shaped grooves 5, to rotate synchronously. However, since the turntable 4 is slidably inserted into the pressing blade 51, it limits its movement, so that the diameter of the circle formed by the multiple pressing blades 51 can be adjusted to control the pressing depth.

[0031] To ensure rotational stability, an electromagnetic ring 6 is fixedly installed at one end of the rotating rod 31. A drive gear 61 is rotatably connected to the outer surface of the rotating rod 31 via a bearing. The electromagnetic ring 6 is electrically connected via a conductive slip ring. The rotating rod 31 is fixedly installed with the electromagnetic ring 6 to drive its rotation. The rotating rod 31 and the drive gear 61 are rotatably connected via a bearing. While fixing the rod, the rotation is not affected, so as to ensure rotational stability and allow the electromagnetic ring 6 to maintain a continuous electrical connection with external equipment during rotation, avoiding the interruption of electrical connection caused by rotation.

[0032] In order to adjust the circular diameter formed by multiple grass-pressing blades 51, the inner side of the drive gear 61 is magnetically connected to the outer surface of the electromagnetic ring 6 through an adsorption component. The drive gear 61 meshes with the rotating gear 41 and is magnetically connected to the electromagnetic ring 6 through the adsorption component. The electromagnetic ring 6 is connected to the power supply through a conductive slip ring. When the electromagnetic ring 6 is energized, the drive gear 61 is fixed to it, and the two rotate synchronously. The drive gear 61 meshes with the rotating gear 41, driving the rotating gear 41 to rotate. This causes the grass-pressing blades 51 to move on the slidably inserted turntable 4 through the arc-shaped groove 5 on the rotating gear 41, thereby adjusting the circular diameter formed by the multiple grass-pressing blades 51.

[0033] By setting up a straw-pressing device, the straw mat is flattened. When the fixed electromagnet 42 is energized, the rotating gear 41 is fixed to the turntable 4 via an adsorption component, allowing them to rotate synchronously. When the fixed electromagnet 42 is de-energized, the rotating gear 41 can rotate independently of the turntable 4, thus desynchronizing the rotation of the turntable 4 and the rotating gear 41. Multiple arc-shaped grooves 5 are formed on the outer surface of the rotating gear 41. The electromagnetic ring 6 is connected to the power supply via a conductive slip ring, and the drive gear 61 is fixed to it, allowing them to rotate synchronously. The drive gear 61 meshes with the rotating gear 41, thereby… The rotating gear 41 drives the grass-pressing blade 51, which is slidably connected to the inner wall of the arc-shaped groove 5, to rotate synchronously. However, since the turntable 4 is slidably inserted into the grass-pressing blade 51, it limits its movement, allowing the diameter of the circle formed by multiple grass-pressing blades 51 to be adjusted to control the grass-pressing depth. This solves the technical problem in the prior art where the diameter of the grass-pressing blade is fixed, making it difficult to achieve precise depth control, resulting in grass pressing that is too shallow and the grass mat is not firmly fixed, or too deep, causing unnecessary soil disturbance and affecting the ecological environment.

[0034] Working principle: When the drive frame 1 needs to move, the drive motor 2 is started to drive the drive rod 21 to rotate, which drives the front drive wheel of the track wheel 3 fixedly installed thereto to rotate, thereby transmitting power to the track chain. The track chain drives the rear drive wheel to rotate, thereby driving the rotating rod 31 to rotate on the rotatingly connected frame 1. When the grass compaction depth needs to be adjusted during operation, the rotating rod 31 drives the electromagnetic ring 6 to rotate. The electromagnetic ring 6 is connected to the power supply through a conductive slip ring. When the electromagnetic ring 6 is energized, the fixed electromagnet 42 on the turntable 4 is de-energized, and the mobile motor 43 fixedly installed on the turntable 4 is also in the off state. The drive gear 61 is fixed to the electromagnetic ring 6, and the two rotate synchronously. The drive gear 61 meshes with the rotating gear 41, and drives the rotating gear 41 to rotate on the support rod of the turntable 4. The arc groove 5 opened on the rotating gear 41 drives the grass compaction blade 51 slidably connected to it to rotate synchronously. However, since the turntable 4 and the grass compaction blade 51 are slidably inserted, they are limited and can only move, thereby adjusting the diameter of the circle formed by multiple grass compaction blades 51. Since the diameter adjustment is completed instantly, the diameter adjustment can be avoided from being affected by the rotation of the grass compaction blade 51 due to traction force. After adjustment, the electromagnetic ring 6 is de-energized and released from the drive gear 61. The fixed electromagnet 42 is energized, and the rotating gear 41 is fixed on the turntable 4 through the adsorption component. At the same time, the moving motor 43 is started to drive the turntable 4 to rotate, thereby driving the grass-pressing blade 51, which is slidably inserted into the turntable 4, to rotate. Since the rotating gear 41 is fixed to the turntable 4, the two rotate synchronously and are in a relatively stationary state, ensuring that the grass-pressing blade 51 maintains a consistent diameter during operation and avoiding unnecessary adjustment deviations.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
