Abstract
Description
Technical Field
[0001] This utility model relates to the field of tree root grinding machine technology, and in particular to a tree root grinding machine. Background Technology
[0002] Tree root grinders (also known as stump crushers) are key pieces of equipment used in landscaping, forestry, and municipal maintenance to remove residual tree roots after felling. They use high-speed rotating carbide blades to cut underground tree roots into fragments, thus efficiently removing the roots and avoiding the problems of high cost, low efficiency, and environmental damage associated with traditional digging methods.
[0003] Currently, while traditional root grinding machines on the market have largely achieved the core function of root crushing, they suffer from significant shortcomings in mobility. Existing equipment typically employs an integral structure or limited sway steering, with the machine body fixedly connected to the chassis, making independent large-angle rotation impossible. At construction sites, especially in complex environments with confined spaces and numerous obstacles, operators must frequently move the entire machine back and forth to "find the right position" in order to adjust the cutting angle. This process is not only time-consuming and labor-intensive but also demands a high level of operator experience, resulting in low overall operational efficiency. Therefore, this application proposes a root grinding machine to address these problems. Utility Model Content
[0004] Based on this, in order to solve the problems existing in the prior art, this application provides a tree root grinding machine, including a base, and the base is provided with a wheel assembly;
[0005] Mounting base, which is horizontally rotatably mounted on the upper surface of the base;
[0006] The drive mechanism is mounted on the upper surface of the mounting base;
[0007] A cutting assembly is located at one end of the mounting base, and the drive mechanism is connected to the cutting assembly via a transmission assembly.
[0008] The control frame is located at the other end of the mounting base.
[0009] Furthermore, the base is provided with a connector, one end of which is fixedly connected to the base, and the other end extends into the interior of the mounting base. A thrust bearing is fitted on the outer wall of the connector, one end of which abuts against the base, and the other end protrudes from the base and abuts against the mounting base.
[0010] Furthermore, the bottom of the base is provided with an arc-shaped first limiting hole, the center of which is located on the rotation axis of the mounting base. The bottom of the mounting base is provided with a limiting rod, one end of which is fixedly connected to the mounting base, and the other end extends into the first limiting hole.
[0011] Furthermore, the wheel assembly includes a first axle and rollers, the first axle being mounted on a base and the rollers being movably fitted onto both ends of the first axle.
[0012] Furthermore, the cutting assembly includes a second rotating shaft and a cutter head. The two ends of the second rotating shaft are rotatably connected to the mounting base, and one end of the second rotating shaft passes through the mounting base and extends to the outside of the mounting base. The cutter head is fixedly sleeved on the second rotating shaft.
[0013] Furthermore, the transmission assembly includes a first transmission wheel, a second transmission wheel, and a transmission belt. The first transmission wheel is located at the output end of the drive mechanism, and the second transmission wheel is fixedly sleeved on one end of the second rotating shaft extending to the periphery of the mounting base. The first transmission wheel and the second transmission wheel are connected by a transmission belt.
[0014] Furthermore, the control frame includes a first bracket and a second bracket, the first bracket being disposed at the end of the mounting base away from the cutting assembly, and one end of the second bracket being rotatably connected to both sides of the first bracket.
[0015] Furthermore, the first bracket has connecting plates on both sides, and one end of the second bracket is hinged to the two connecting plates. The connecting plates are provided with several second limiting holes, and pins are inserted into the second limiting holes. The second bracket can be fixedly connected to the connecting plates by the pins.
[0016] Furthermore, the first bracket is equipped with a mounting plate, and a control lever is mounted on the mounting plate.
[0017] Furthermore, a spring lock is provided inside the mounting base, and a lock cylinder is slidably installed inside the spring lock. One end of the lock cylinder can be inserted into the base to restrict the rotation of the mounting base.
[0018] Beneficial effects: By setting the mounting base and the base to be rotatable relative to each other, the machine body and the base can rotate independently at a large angle. When the cutting angle of the cutting component needs to be adjusted, it can be quickly adjusted without moving the entire machine body, saving time and effort and further improving work efficiency.

[0031] like Figure 1-3 As shown, this application provides a root grinding machine, including: a base 1, and a wheel assembly 11 disposed on the base 1;
[0032] The wheel assembly 11 includes a first axle 111 and a roller 112. The first axle 111 is mounted on the base 1, and the roller 112 is movably sleeved on both ends of the first axle 111.
[0033] Mounting base 2 is horizontally rotatably mounted on the upper surface of base 1. Rollers 112 are located on both sides of mounting base 2, and a certain distance is provided between mounting base 2 and rollers 112 on both sides.
[0034] Drive mechanism 3 is mounted on the upper surface of mounting base 2;
[0035] Cutting component 4 is disposed at one end of mounting base 2, and driving mechanism 3 is connected to cutting component 4 through a transmission component 5.
[0036] Control frame 6 is located at the other end of mounting base 2.
[0037] In this embodiment, at least one set of wheel assemblies 11 is provided, the length of the mounting base 2 is longer than that of the base 1, and the end of the mounting base 2 where the cutting assembly 4 is mounted is provided as a groove with the opening facing downwards;
[0038] The drive mechanism 3 is an electric motor or an internal combustion engine, which provides power for the operation of the cutting component 4;
[0039] The control frame 6 can control the steering, operation, and parking of the root grinder;
[0040] When in operation, the drive mechanism 3 is activated to drive the cutting component 4 to cut the tree roots. When it is necessary to adjust the cutting angle and turn the cutting component 4, it is only necessary to control the control frame 6 to make the mounting base 2 rotate relative to the base 1 to adjust the cutting component 4 without moving the entire machine body.
[0041] This application sets the mounting base 2 and the base 1 to be rotatable relative to each other, so that the machine body and the base 1 can rotate independently at a large angle. When the cutting angle of the cutting component 4 needs to be adjusted, it can be quickly adjusted without moving the entire machine body, saving time and effort and further improving work efficiency.
[0042] In one embodiment, the base 1 is provided with a connector 21. One end of the connector 21 is fixedly connected to the base 1, and the other end extends into the interior of the mounting base 2. A thrust bearing 211 is sleeved on the outer wall of the connector 21. One end of the thrust bearing 211 abuts against the base 1, and the other end protrudes from the base 1 and abuts against the mounting base 2.
[0043] In this embodiment, the thrust bearing 211 is partially embedded in the base 1, the connector 21 is cylindrical or cylindrical, and the other end of the connector 21 extends into the mounting base 2 and is rotatably connected to the mounting base 2.
[0044] Thrust bearing 211 is prior art, a rolling bearing specifically designed to withstand loads (axial loads) in the axial direction. The structure includes two washers: a shaft ring (tightly fitted to the shaft) and a housing ring (tightly fitted to the bearing housing), and a cage: a cage assembly containing steel balls that roll on the raceways of the two washers.
[0045] Furthermore, the connector 21 extending into the mounting base 2 is fitted with a retaining ring 212, and an annular groove 213 is provided on the outer wall of the connector 21 near the retaining ring 212, with the annular groove 213 located above the retaining ring 212.
[0046] With this configuration, if the mounting base 2 is about to detach from the connector 21 during operation, the mounting base 2 will cause the retaining spring 212 to slide toward the slot 213. When the retaining spring 212 slides into the slot 213, the retaining spring 212 is locked by the slot 213 and cannot slide any further, thereby restricting the mounting base 2 from continuing to slide and achieving the purpose of preventing the mounting base 2 from detaching from the connector 21.
[0047] like Figure 4 As shown, in one embodiment, the bottom of the base 1 is provided with an arc-shaped first limiting hole 12, the center of the first limiting hole 12 is located on the rotation axis of the mounting base 2, and the bottom of the mounting base 2 is provided with a limiting rod 22, one end of the limiting rod 22 is fixedly connected to the mounting base 2, and the other end extends into the first limiting hole 12.
[0048] In this embodiment, the first limiting hole 12 is a blind hole or a through hole, and the angle between the two ends of the first limiting hole 12 and the center of the circle is the adjustable angle range of the body.
[0049] Specifically, when the mounting base 2 rotates, it drives the limiting rod 22 to slide synchronously in the first limiting hole 12. When the limiting rod 22 slides to both ends of the first limiting hole 12, it is blocked by the first limiting hole 12. At this time, the limiting rod 22 stops sliding, and the mounting base 2 also reaches the maximum adjustment angle.
[0050] In one embodiment, the cutting assembly 4 includes a second rotating shaft 41 and a cutter head 42. The two ends of the second rotating shaft 41 are rotatably connected to the mounting base 2, and one end of the second rotating shaft 41 passes through the mounting base 2 and extends to the outside of the mounting base 2. The cutter head 42 is fixedly sleeved on the second rotating shaft 41.
[0051] In this embodiment, the mounting base 2 has a notch at one end near the cutter head 42, and part of the cutter head 42 extends from bottom to top through the mounting base 2, with several blades provided on the blade.
[0052] like Figure 5 As shown, in one embodiment, the transmission assembly 5 includes a first transmission wheel 51, a second transmission wheel 52, and a transmission belt 53. The first transmission wheel 51 is disposed at the output end of the drive mechanism 3, and the second transmission wheel 52 is fixedly sleeved on one end of the second rotating shaft 41 extending to the periphery of the mounting base 2. The first transmission wheel 51 and the second transmission wheel 52 are connected by the transmission belt 53.
[0053] In this embodiment, the drive mechanism 3 drives the first transmission wheel 51 to rotate, and the first transmission wheel 51 drives the second transmission wheel 52 to rotate synchronously through the transmission belt 53. The rotation of the second transmission wheel 52 drives the second rotating shaft 41 to rotate, and the rotation of the second rotating shaft 41 drives the cutter head 42 to rotate. The rotation of the cutter head 42 can cut and crush the tree roots.
[0054] In one embodiment, the control frame 6 includes a first bracket 61 and a second bracket 62. The first bracket 61 is disposed at one end of the mounting base 2 away from the cutting component 4, and one end of the second bracket 62 is rotatably connected to both sides of the first bracket 61.
[0055] In this embodiment, a handrail 63 is provided at the other end of the second bracket 62;
[0056] The second bracket 62 is rotatably connected to the first bracket 61, so that the included angle between the second bracket 62 and the first bracket 61 is adjustable, and the second bracket 62 can be folded, reducing the space occupied during storage and transportation when not in operation.
[0057] In one embodiment, the first bracket 61 is provided with connecting plates 64 on both sides, and one end of the second bracket 62 is hinged to the two connecting plates 64. The connecting plates 64 are provided with a plurality of second limiting holes 641, and pins 65 are inserted into the second limiting holes 641. The second bracket 62 can be fixedly connected to the connecting plates 64 by the pins 65.
[0058] In this embodiment, different second limiting holes 641 correspond to different included angles between the second bracket 62 and the first bracket 61;
[0059] The second bracket 62 has through holes on both sides corresponding to the second limiting hole 641. When the second bracket 62 is fixed, the pin 65 is inserted into the second limiting hole 641 after passing through the through holes on both sides of the second bracket 62, so that the second bracket is fixed. When the second bracket 62 is adjusted, the pin 65 is pulled out from the second limiting hole 641.
[0060] In one embodiment, the first bracket 61 is provided with a mounting plate 7, and a control lever 71 is provided on the mounting plate 7.
[0061] In this embodiment, the operator can control the root grinder to cut tree roots and park the machine at any time by pulling the control lever 71.
[0062] In one embodiment, a protective shell 23 is provided at one end of the mounting base 2 near the cutter head 42, and the protective shell 23 covers part of the periphery of the cutter head 42.
[0063] In this embodiment, the protective shell 23 is disposed on the periphery of the cutter head 42 above the mounting base 2. It can block the tree root fragments cut by the cutter head 42, prevent the tree root fragments from being carried away by the high-speed rotating cutter head 42 and prevent workers from accidentally touching them and causing injury.
[0064] In one embodiment, a baffle 24 is provided at the bottom of the mounting base 2 near the cutter head 42.
[0065] In this embodiment, the baffle 24 is disposed on the periphery of the cutter head 42 below the mounting base 2. The baffle 24 can block the tree root fragments cut by the cutter head 42 and prevent the tree root fragments from being scattered around by the high-speed rotating cutter head 42.
[0066] In one embodiment, a traction rod 8 is also included, which is disposed at one end of the mounting base 2 near the cutting assembly 4.
[0067] In this embodiment, the traction rod 8 is used to connect the root grinder to other traction equipment, such as a tractor. The traction rod 8 is detachably installed on the end of the mounting base 2 near the cutting assembly 4.
[0068] In one embodiment, the mounting base 2 is further provided with at least one handle 25.
[0069] In this embodiment, there is one handle 25, which is arranged in an inverted U-shape and is located at one end of the mounting base 2 near the cutter head 42. The handle 25 facilitates the handling and movement of the root grinder.
[0070] In one embodiment, a brake hub 9 is provided on the side of the roller 112 near the base 1.
[0071] In this embodiment, by setting a brake drum 9, and the brake drum 9 can be controlled by a control lever 71 to brake, the purpose of parking is achieved. This is prior art and will not be described in detail here.
[0072] like Figure 6 As shown, in one embodiment, a spring lock 26 is provided inside the mounting base 2, and a lock cylinder 261 is slidably disposed inside the spring lock 26. The base 1 has a hole that matches the lock cylinder 261. When one end of the lock cylinder 261 extends through the hole of the mounting base 2 and the base 1 into the interior of the base 1, the base 1 and the mounting base 2 are relatively fixed, restricting the rotation of the mounting base 2. The other end of the lock cylinder 261 is connected to the control rod 71 through a pull wire 72.
[0073] Among them, a spring 262 is provided between the outside of the lock cylinder 261 and the inner wall of the spring lock 26 housing. The spring 262 can drive the lock cylinder 261 to reset.
[0074] When in operation, pulling the control lever 71 will cause the connected pull cable 72 to pull the lock cylinder 261 upward into the mounting base 2. At this time, the lock cylinder 261 no longer restricts the mounting base 2, and the mounting base 2 can rotate relative to the base 1. After the control lever 71 is reset, one end of the lock cylinder 261, under the action of the spring 262, causes the lock cylinder 261 to extend through the hole of the mounting base 2 and the base 1 into the interior of the base 1. At this time, the mounting base 2 is locked to the base 1 and cannot be rotated.
[0075] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
