Description

Technical Field

[0001] This utility model relates to the field of loader technology, specifically a skid steer loader. Background Technology

[0002] In coal mining operations, the complexity of the underground environment and the stringent requirements of construction pose extremely high challenges to engineering equipment. Furthermore, underground coal mining operations encompass multiple stages, including material loading and transportation, roadway support, dredging, and crushing, but existing engineering equipment has relatively limited functionality. When handling large pieces of gangue or rock, traditional loaders, relying solely on their standard buckets, are insufficient for crushing, necessitating the use of additional crushing equipment, increasing equipment investment and operating costs. For maintenance work such as roadway deformation repair and anchor bolt / cable support, existing equipment is even less capable, requiring reliance on manual labor or specialized equipment, resulting in low construction efficiency. Utility Model Content

[0003] The purpose of this utility model is to provide a skid steer loader to solve the problem of low construction efficiency caused by the single function of existing engineering equipment.

[0004] This utility model provides a skid steer loader, including: a loader body, an auxiliary mechanism, an adjustment mechanism, a mounting mechanism, and a moving mechanism. One end of the adjustment mechanism is connected to the loader body, and the other end of the adjustment mechanism is detachably connected to the auxiliary mechanism through the mounting mechanism. The moving mechanism is disposed at the bottom of the loader body and is used to drive the loader body to move. The adjustment mechanism is used to adjust the positional relationship between the auxiliary mechanism and the loader body.

[0005] The auxiliary mechanism includes a connecting sleeve and an actuator. The connecting sleeve is disposed on the actuator and has a slot. The actuator includes any one of a bucket assembly, a digging arm assembly, a hydraulic mixing tank assembly, a gripper assembly, and a forklift arm assembly.

[0006] The installation mechanism includes a docking box and a plug rod. The docking box is embedded in the connecting sleeve and has a through hole. The plug rod is disposed inside the docking box and its end can extend toward the outside of the docking box toward the through hole. When the plug rod passes through the through hole and is placed in the slot, the installation mechanism is fixed to the auxiliary mechanism.

[0007] Furthermore, the mounting mechanism also includes a screw and a trapezoidal slider. The insertion rod includes a first sub-rod and a second sub-rod. The trapezoidal slider is disposed between the first sub-rod and the second sub-rod. The trapezoidal slider is provided with a screw hole, and the trapezoidal slider is threadedly connected to the screw through the screw hole.

[0008] When the screw drives the trapezoidal slider to slide along the screw in a first direction, the first sub-rod and the second sub-rod move in opposite directions, and the ends of the first sub-rod and the second sub-rod respectively pass through the corresponding through holes on the docking box and are inserted into the corresponding slots on the auxiliary mechanism.

[0009] Furthermore, the installation mechanism also includes a limiting block and a spring. The limiting block is provided on the first sub-rod near the trapezoidal slider and on the second sub-rod near the trapezoidal slider. When the ends of the first sub-rod and the second sub-rod pass through the corresponding through holes on the docking box and are inserted into the corresponding slots on the auxiliary mechanism, the limiting block abuts against the inner wall of the docking box.

[0010] The two ends of the spring are respectively connected to the first sub-rod and the second sub-rod. When the first sub-rod and the second sub-rod move in opposite directions, the elastic potential energy of the spring increases.

[0011] Furthermore, the mounting mechanism also includes a worm gear and a worm. The worm gear is coaxially arranged with the screw, and the worm meshes with the worm gear. The worm drives the screw to rotate in the forward direction through the worm gear, thereby driving the trapezoidal slider to slide on the screw along the first direction.

[0012] Furthermore, the screw is a bidirectional screw, and each end of the bidirectional screw is provided with a trapezoidal slider, and each trapezoidal slider corresponds to one insertion rod.

[0013] Furthermore, the adjustment mechanism includes a fixed plate, a connecting rod, a first hydraulic rod, a connecting arm, a crossbar, and a second hydraulic rod. The adjustment mechanism is mounted on the loader body via the fixed plate. The connecting rod and the first hydraulic rod are positioned between the fixed plate and the connecting arm. The connecting rod is adjusted to a first angle via the first hydraulic rod, where the first angle is the angle between the connecting rod and the connecting arm. The crossbar is positioned between two opposing connecting arms. One end of the second hydraulic rod is mounted on the crossbar, and the other end of the second hydraulic rod is connected to the mounting mechanism. The end of the connecting arm is movably connected to the mounting mechanism. The connecting arm is adjusted to a second angle via the second hydraulic rod, where the second angle is the angle between the connecting arm and the mounting mechanism.

[0014] Furthermore, the loader body includes a housing and an engine, oil tank, hydraulic pump, and multi-way valve disposed within the housing. The input end of the hydraulic pump is connected to the output end of the engine. The inlet end of the hydraulic pump is connected to the oil tank via a pipe. The outlet end of the hydraulic pump is connected to the inlet end of the multi-way valve via a pipe. The outlet end of the multi-way valve is connected to the oil tank. The auxiliary mechanism, the adjusting mechanism, and the mounting mechanism are respectively connected to the multi-way valve via corresponding pipelines.

[0015] Furthermore, the loader body also includes a storage box for storing at least one of the bucket assembly, the digging arm assembly, the hydraulic mixing tank assembly, the gripper assembly, and the forklift arm assembly.

[0016] Furthermore, the moving mechanism includes a drive motor and a moving wheel, with the output shaft of the drive motor connected to the rotation shaft of the moving wheel.

[0017] Furthermore, the movable wheels are provided with anti-slip textures.

[0018] In this embodiment of the utility model, the loader body provides the power and operating platform, and the moving mechanism drives the loader to move; the adjusting mechanism can flexibly adjust the positional relationship between the auxiliary mechanism and the loader body to meet the needs of different working postures; the installation mechanism realizes the detachable connection between the auxiliary mechanism and the adjusting mechanism, so that the skid steer loader can quickly replace the bucket assembly, digging arm assembly, hydraulic mixing tank assembly, gripper assembly and forklift arm assembly to meet the diverse operating needs of shoveling, digging, mixing and grabbing.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0033] The terms "first," "second," etc., used in the specification and claims of this utility model are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such usage can be interchanged where appropriate so that embodiments of this utility model can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, the first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0034] like Figures 1 to 11 As shown, this utility model provides a skid steer loader, including: a loader body 1, an auxiliary mechanism 2, an adjustment mechanism 3, a mounting mechanism 4, and a moving mechanism 5. One end of the adjustment mechanism 3 is connected to the loader body 1, and the other end of the adjustment mechanism 3 is detachably connected to the auxiliary mechanism 2 through the mounting mechanism 4. The moving mechanism 5 is located at the bottom of the loader body 1 and is used to drive the loader body 1 to move. The adjustment mechanism 3 is used to adjust the positional relationship between the auxiliary mechanism 2 and the loader body 1.

[0035] The auxiliary mechanism 2 includes a connecting sleeve 201 and an actuator. The connecting sleeve 201 is mounted on the actuator and has a slot 2011. The actuator includes any one of a bucket assembly 202, a digging arm assembly 203, a hydraulic mixing tank assembly 204, a gripper assembly 205, and a forklift arm assembly 206.

[0036] The mounting mechanism 4 includes a docking box 401 and a plug rod 402. The docking box 401 is embedded in the connecting sleeve 201 and has a through hole. The plug rod 402 is disposed inside the docking box 401 and its end can extend toward the outside of the docking box 401 toward the through hole. When the plug rod 402 passes through the through hole and is placed in the slot 2011, the mounting mechanism 4 is fixed with the auxiliary mechanism 2.

[0037] In this embodiment, the loader body 1 provides the power and operating platform, and the moving mechanism 5 drives the loader to move. The adjusting mechanism 3 can flexibly adjust the positional relationship between the auxiliary mechanism 2 and the loader body 1 to meet the needs of different working postures. The mounting mechanism 4 realizes the detachable connection between the auxiliary mechanism 2 and the adjusting mechanism 3, so that the skid steer loader can quickly replace the bucket assembly 202, the digging arm assembly 203, the hydraulic mixing tank assembly 204, the gripper assembly 205 and the forklift arm assembly 206 to meet the diverse operating needs of shoveling, digging, mixing and grabbing. Through the modular design of the auxiliary mechanism 2 and the nested arrangement of the docking box 401 and the connecting sleeve 201, the rapid switching of the detachable structure is realized, which effectively solves the problem of single function and low construction efficiency of traditional engineering equipment, and improves the adaptability and continuous operation efficiency of the single machine in multi-condition construction.

[0038] Optionally, the mounting mechanism 4 also includes a screw 403 and a trapezoidal slider 404. The insertion rod 402 includes a first sub-rod and a second sub-rod. The trapezoidal slider 404 is disposed between the first sub-rod and the second sub-rod. The trapezoidal slider 404 is provided with a screw hole, and the trapezoidal slider 404 is threadedly connected to the screw 403 through the screw hole.

[0039] When the screw 403 drives the trapezoidal slider 404 to slide along the first direction on the screw 403, the first sub-rod and the second sub-rod move in opposite directions. The ends of the first sub-rod and the second sub-rod pass through the corresponding through holes on the docking box 401 and are inserted into the corresponding slots 2011 on the auxiliary mechanism 2.

[0040] In this embodiment, the threaded connection between the screw 403 and the trapezoidal slider 404 constructs a linkage-type plug-in structure, which can convert the rotational motion of the screw 403 into the linear motion of the trapezoidal slider 404. Each plug 402 may include a first sub-rod and a second sub-rod, and the trapezoidal slider 404 is disposed between the first sub-rod and the second sub-rod. When the screw 403 drives the trapezoidal slider 404 to slide along the first direction, the pushing action of the trapezoidal inclined surface causes the first sub-rod and the second sub-rod to move in opposite directions, and their ends synchronously pass through the docking box 401. The corresponding through hole on the upper part is precisely inserted into the slot 2011 of the connecting sleeve 201 of the auxiliary mechanism 2, forming a bidirectional symmetrical insertion and locking. Through the stability of the threaded transmission and the guiding nature of the trapezoidal slider, the insertion rod 402 is quickly opened and positioned and reliably mechanically connected, thereby realizing the detachable connection between the installation mechanism 4 and the auxiliary mechanism 2. This facilitates the quick replacement of the bucket assembly 202, the digging arm assembly 203, the hydraulic mixing tank assembly 204, the gripper assembly 205, and the forklift arm assembly 206, meeting diverse operational needs such as shoveling, digging, mixing, and grabbing.

[0041] It should be understood that the first direction can be either left or right, depending on the orientation of the trapezoidal inclined plane, so that when the trapezoidal slider 404 slides along the first direction, the first sub-rod and the second sub-rod corresponding to the trapezoidal slider 404 will move in opposite directions.

[0042] Optionally, the mounting mechanism 4 also includes a limiting block 405 and a spring 406. Limiting blocks 405 are respectively provided on the first sub-rod near the trapezoidal slider 404 and on the second sub-rod near the trapezoidal slider 404. When the ends of the first sub-rod and the ends of the second sub-rod pass through the corresponding through holes on the docking box 401 and are inserted into the corresponding slots 2011 on the auxiliary mechanism 2, the limiting block 405 abuts against the inner wall of the docking box 401.

[0043] The two ends of the spring 406 are connected to the first sub-rod and the second sub-rod, respectively. When the first sub-rod and the second sub-rod move in opposite directions, the elastic potential energy of the spring 406 increases.

[0044] In this embodiment, both the first sub-rod and the second sub-rod are provided with limiting blocks 405 near the trapezoidal slider 404. The limiting blocks 405 can prevent the first sub-rod and the second sub-rod from moving excessively. When the ends of the two sub-rods are inserted into the slots 2011 of the auxiliary mechanism 2, the limiting blocks 405 abut against the inner wall of the docking box 401, accurately limiting the extension stroke of the insertion rod and ensuring that the insertion depth meets the design requirements.

[0045] Furthermore, the two ends of the spring 406 are connected to the first sub-rod and the second sub-rod respectively. When the trapezoidal slider 404 drives the sub-rods to move in opposite directions, the spring is stretched and stores elastic potential energy. When the auxiliary mechanism 2 needs to be disassembled, the spring 406 releases the elastic potential energy, assists the first sub-rod and the second sub-rod to move in opposite directions, so that the insertion rod 402 retracts, which facilitates quick disassembly and improves work efficiency.

[0046] Optionally, the mounting mechanism 4 further includes a worm gear 407 and a worm 408. The worm gear 407 is coaxially arranged with the screw 403, and the worm 408 meshes with the worm gear 407. The worm 408 drives the screw 403 to rotate in the forward direction through the worm gear 407, so as to drive the trapezoidal slider 404 to slide on the screw 403 along the first direction.

[0047] In this embodiment, the worm gear 407 and the screw 403 are coaxially fixedly connected. The worm 408 meshes with the worm gear 407 to form a reduction transmission pair. When the worm 408 rotates under the drive of an external force (such as a motor), the meshing relationship of the worm gear drives the screw 403 to rotate in the forward direction, thereby causing the trapezoidal slider 404, which is threadedly connected to the screw 403, to slide in the first direction, pushing the first sub-rod and the second sub-rod to move in opposite directions and insert into the slot 2011 of the auxiliary mechanism 2 to fix the auxiliary mechanism 2. When it is necessary to disassemble the auxiliary mechanism 2, the meshing relationship of the worm gear drives the screw 403 to rotate in the forward direction. The moving screw 403 rotates in the opposite direction, causing the trapezoidal slider 404, which is threadedly connected to the screw 403, to slide in the second direction, pushing the first sub-rod and the second sub-rod to move towards each other. The first sub-rod and the second sub-rod move out of the slot 2011 of the auxiliary mechanism 2 to unlock the auxiliary mechanism 2. This realizes the detachable connection between the installation mechanism 4 and the auxiliary mechanism 2, which facilitates the quick replacement of the bucket assembly 202, the digging arm assembly 203, the hydraulic mixing tank assembly 204, the gripper assembly 205, and the forklift arm assembly 206, meeting the diverse operational needs of shoveling, digging, mixing, and grabbing.

[0048] In this way, by utilizing the characteristics of stable transmission ratio, strong self-locking (preventing reverse rotation of the screw), and smooth operation of worm gear transmission, it is possible to ensure that the trapezoidal slider obtains sufficient driving force through speed reduction and torque increase, and to lock the screw position by using the self-locking function of the worm gear after insertion, so as to avoid the insertion rod from loosening due to vibration during operation, thereby improving the reliability and operational safety of the installation mechanism from the power transmission level.

[0049] Optionally, the screw 403 is a bidirectional screw, and each end of the bidirectional screw is provided with a trapezoidal slider 404, and each trapezoidal slider 404 corresponds to a plug 402.

[0050] In this embodiment, the two ends of the bidirectional screw are respectively provided with threads of opposite directions (such as left and right threads), and each thread segment corresponds to a trapezoidal slider 404. Each slider is connected to a set of insertion rods 402 (i.e., the first sub-rod and the second sub-rod). When the bidirectional screw rotates, the trapezoidal sliders at both ends slide synchronously in opposite directions (such as the first direction and the second direction) along the screw axis based on the difference in thread direction, pushing the corresponding insertion rods outward to open them up, so that the ends of the two sets of insertion rods pass through the through holes of the docking box and are inserted into the corresponding slots of the auxiliary mechanism 2 at the same time. Through the synchronous transmission characteristics of the bidirectional screw, the symmetrical insertion action of the two insertion rods is realized. Compared with the single screw drive, it can provide a more balanced clamping force, avoid connection deviation caused by unilateral force, improve the stability and centering of the auxiliary mechanism during installation, and at the same time, the self-synchronization characteristics of the bidirectional thread simplify the control logic and ensure a fast and reliable mechanical connection.

[0051] It should be understood that having threads with the same direction of rotation at both ends of a bidirectional screw can achieve the same technical effect, which will not be elaborated further here.

[0052] Optionally, the adjustment mechanism 3 includes a fixed plate 301, a connecting rod 302, a first hydraulic rod 303, a connecting arm 304, a crossbar 305, and a second hydraulic rod 306. The adjustment mechanism 3 is mounted on the loader body 1 via the fixed plate 301. The connecting rod 302 and the first hydraulic rod 303 are positioned between the fixed plate 301 and the connecting arm 304. The connecting rod 302 is adjusted to a first angle via the first hydraulic rod 303. The first angle is the angle between the connecting rod 302 and the connecting arm 304. The crossbar 305 is positioned between two opposite connecting arms 304. One end of the second hydraulic rod 306 is mounted on the crossbar 305, and the other end of the second hydraulic rod 306 is connected to the mounting mechanism 4. The end of the connecting arm 304 is movably connected to the mounting mechanism 4. The connecting arm 304 is adjusted to a second angle via the second hydraulic rod 306. The second angle is the angle between the connecting arm 304 and the mounting mechanism 4.

[0053] In this embodiment, the fixed plate 301 serves as the fixed base of the adjustment mechanism 3 and is rigidly connected to the loader body 1. A rotatable connecting rod 302 and a first hydraulic rod 303 are provided between the fixed plate 301 and the connecting arm 304. The first angle between the connecting rod 302 and the connecting arm 304 is changed by the extension and retraction of the first hydraulic rod, thereby realizing the pitching action of the connecting arm 304 (such as raising or lowering the auxiliary mechanism). Furthermore, the two connecting arms 304 are rigidly connected by a crossbar 305 to enhance the stability of the connecting arm 304. A second hydraulic rod 306 is provided between the crossbar 305 and the mounting mechanism 4. The end of the connecting arm 304 is hinged to the mounting mechanism 4. When the second hydraulic rod 306 extends and retracts, it drives the mounting mechanism 4 to rotate around the hinge point, thereby changing the second angle between the connecting arm 304 and the mounting mechanism 4, thereby realizing the angle tilt adjustment of the auxiliary mechanism 2 (such as tilting the bucket forward or backward). In this way, through the independent or coordinated action of the first hydraulic rod 303 and the second hydraulic rod 306, the auxiliary mechanism 2 has the ability to perform combined vertical lifting and tilting motions, which can adapt to the posture requirements under various working conditions such as material loading, excavation, and leveling, thereby improving the flexibility and accuracy of operation.

[0054] Optionally, the loader body 1 includes a housing 101 and an engine 102, an oil tank 103, a hydraulic pump 104, and a multi-way valve 105 disposed within the housing 101. The input end of the hydraulic pump 104 is connected to the output end of the engine 102. The inlet end of the hydraulic pump 104 is connected to the oil tank 103 through a pipe. The outlet end of the hydraulic pump 104 is connected to the inlet end of the multi-way valve 105 through a pipe. The outlet end of the multi-way valve 105 is connected to the oil tank 103. The auxiliary mechanism 2, the adjusting mechanism 3, and the mounting mechanism 4 are respectively connected to the multi-way valve 105 through corresponding pipelines.

[0055] In this embodiment, the housing 101 serves as a support platform for the internally integrated components such as the engine 102, oil tank 103, hydraulic pump 104, and multi-way valve 105. The output end of the engine 102 is mechanically connected to the input end of the hydraulic pump 104 (e.g., via belt, gear, or coupling), driving the hydraulic pump to rotate. The hydraulic pump 104 draws hydraulic oil from the oil tank 103 through a suction pipe at its inlet end, pressurizes it, and then delivers it to the inlet end of the multi-way valve 105 through an outlet pipe. The multi-way valve 105 distributes the high-pressure oil to auxiliary mechanisms 2 (e.g., the actuator hydraulic motor), adjusting mechanisms 3 (e.g., the first and second hydraulic rods), and mounting mechanisms 4 (e.g., the insert rod drive cylinder) according to operating commands. The low-pressure oil from each component returns to the oil tank 103 through the return end of the multi-way valve, forming a closed-loop hydraulic cycle. This provides stable hydraulic power to each mechanism, ensuring coordinated and reliable operation of all mechanisms and enabling efficient loader operation. Simultaneously, the hydraulic system facilitates the control and flexible operation of each mechanism.

[0056] Optionally, the loader body 1 also includes a storage box for storing at least one of the bucket assembly 202, the digging arm assembly 203, the hydraulic mixing tank assembly 204, the gripper assembly 205, and the forklift arm assembly 206.

[0057] In this embodiment, the storage box can store various actuators, which facilitates the quick replacement of the auxiliary mechanism 2 in different operating scenarios, reduces the time and manpower costs of finding and moving actuators, and at the same time, centralized storage can effectively protect the actuators, prevent them from being damaged when idle, and improve equipment management efficiency and the service life of the actuators.

[0058] Optionally, the moving mechanism 5 includes a drive motor 501 and a moving wheel 502, with the output shaft of the drive motor 501 connected to the rotation shaft of the moving wheel 502.

[0059] In this embodiment, the drive motor 501 provides power to the moving wheels 502, enabling the loader body 1 to move autonomously. The drive motor 501 has stable power output and is easy to control. It can flexibly adjust the speed and direction of travel according to the operation requirements, so that the skid steer loader can move quickly in different terrains and work areas, improving the mobility and working range of the equipment.

[0060] Optionally, the caster wheel 502 is provided with anti-slip texture.

[0061] In this embodiment, the anti-slip texture on the movable wheel 502 increases the friction with the ground, which can effectively prevent the loader from slipping when driving or operating on complex ground such as wet, muddy or slippery surfaces, improve the stability and safety of the loader during driving and operation, and ensure that the loader can operate reliably under various working conditions.

[0062] Specifically, the working principle of this skid steer loader is as follows: During operation, the engine 102 drives the hydraulic pump 104 to operate. The hydraulic pump 104 draws hydraulic oil from the oil tank 103 and pressurizes it, then delivers it through pipelines to the multi-way valve 105. The multi-way valve 105 then distributes the hydraulic oil as needed to the corresponding pipelines of the auxiliary mechanism 2, the adjusting mechanism 3, and the mounting mechanism 4, providing power to each mechanism. When it is necessary to change the working function, the worm gear 408 is rotated, which drives the screw 403 to rotate through the worm wheel 407. The screw 403 drives the trapezoidal slider 404 to slide, causing the first and second sub-stems of the insert rod 402 to retract, disconnecting the mounting mechanism 4 from the auxiliary mechanism 2, removing the original actuator, taking out the required actuator from the storage box, inserting the docking box 401 into the connecting sleeve 201, and rotating the worm gear 408 again. Rod 408 extends the insertion rod 402 into the insertion slot 2011. Limiting block 405 ensures the insertion rod 402 is accurately positioned. Spring 406 assists in maintaining connection stability. When adjusting the working position and posture, the first hydraulic rod 303 extends and retracts to change the first angle between the connecting rod 302 and the connecting arm 304. The second hydraulic rod 306 extends and retracts to adjust the second angle between the connecting arm 304 and the mounting mechanism 4. The two hydraulic rods work together to realize the position and angle adjustment of the auxiliary mechanism 2 in space. The drive motor 501 of the moving mechanism 5 drives the moving wheel 502 to rotate, enabling the loader to move on the work site. The anti-slip texture on the moving wheel 502 ensures that the loader travels stably on various types of ground. Throughout the process, the various mechanisms cooperate with each other to achieve efficient and flexible operation of the skid steer loader.
