Description

Technical Field

[0001] This utility model relates to the field of loader technology, specifically to a loader working device for mushroom cultivation. Background Technology

[0002] Loaders, as a widely used multi-functional earthmoving and transporting machine, are mainly used in construction sites, ports, stations, freight yards and other places to load or transport loose materials such as soil, sand, gravel, coal and garbage over short distances. They can also perform traction, leveling, stacking and unloading operations, making them a multi-purpose and highly efficient engineering machine.

[0003] In large-scale mushroom cultivation factories in China, using straw (such as rice straw, wheat straw, corn stalks, etc.) as a cultivation substrate is a common and cost-effective method, especially suitable for saprophytic fungi (such as button mushrooms, straw mushrooms, oyster mushrooms, etc.). The straw used as a cultivation substrate needs to be soaked or wetted. Generally, a water storage tank is dug down into the ground, and a loader is used to load and transport the straw into the water storage tank. The bucket is then tilted downwards to completely soak the straw in water, and then the bucket is tilted upwards to transport the straw to the designated location.

[0004] Therefore, there is an urgent need to develop new working devices suitable for loaders in mushroom cultivation, expand the functionality of loaders, and improve their adaptability to different working conditions. Utility Model Content

[0005] To address the problems existing in the prior art, this utility model provides a loader working device for mushroom cultivation. The downward tilting angle of the grass-grabbing implement and the upward tilting force of the bucket cylinder are both large, meeting the requirements of the operating conditions and improving the loader's adaptability. When the hinge point between the boom and the grass-grabbing implement is within 3 meters of the ground, the downward tilting angle of the grass-grabbing implement is above 60°. Furthermore, in this state, the upward tilting force of the bucket cylinder can exceed the rated load by 10%. Simultaneously, the lower clamp of the grass-grabbing implement adopts a closed multi-tooth structure, and the upper clamp adopts a split multi-tooth structure, enabling the simultaneous gripping of two or more materials with different dimensions. This also prevents material spillage during loading and transportation, meeting the operational requirements of mushroom cultivation.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a loader working device for mushroom cultivation, comprising: a grass grabber, a boom, a tie rod, a rocker arm, a tipping cylinder, a boom cylinder, and a main unit. One end of the boom is hinged to the main unit, and the other end is hinged to the grass grabber. The lower middle part of the boom is connected to the main unit through the boom cylinder, which controls the swing of the boom. The middle part of the rocker arm is hinged to the middle part of the boom. The upper end of the rocker arm is connected to the main unit through the tipping cylinder, and the lower end of the rocker arm is connected to the grass grabber through the tie rod. The tipping cylinder controls the grass grabber to swing around the end of the boom.

[0007] Furthermore, the rocker arm and the tipping cylinder, the tipping cylinder and the main unit, the rocker arm and the tie rod, and the tie rod and the grass grabber are connected by hinges.

[0008] Furthermore, the hinge point between the boom and the main unit is higher than the hinge point between the boom cylinder and the main unit.

[0009] Furthermore, the grass-grabbing device includes: an upper clamping body, a hydraulic cylinder, a lower clamping body, an upper pin, and a lower pin. The upper clamping body and the lower clamping body are hinged together on one side, allowing the upper and lower clamping bodies to open and close around the hinge point. One end of the hydraulic cylinder is hinged to the upper clamping body, and the other end is hinged to the lower clamping body. The hydraulic cylinder controls the opening and closing of the upper and lower clamping bodies.

[0010] Furthermore, the lower clamp body adopts a closed multi-tooth structure.

[0011] Furthermore, the upper clamp body adopts a split multi-tooth structure.

[0012] Furthermore, the upper clamp body includes: an upper left clamp body and an upper right clamp body. The upper left clamp body and the upper right clamp body are hinged to the lower clamp body on the same side. The upper left clamp body and the upper right clamp body are respectively connected to the lower clamp body through a hydraulic cylinder, so that the upper left clamp body and the upper right clamp body can open and close independently with the lower clamp body.

[0013] Furthermore, the upper clamp body is also provided with a lever arm and fixed on the upper clamp body, with one end extending above the tool cylinder. The upper clamp body is hinged to the tool cylinder through the lever arm.

[0014] Furthermore, the hinge point between the middle part of the rocker arm and the middle part of the boom is not located on the line connecting the hinge point between the rocker arm and the tipping cylinder and the hinge point between the rocker arm and the pull rod.

[0015] The beneficial effects of this utility model are:

[0016] (1) The upper clamp of the grass grabber adopts a split multi-tooth structure, which can simultaneously grab two or more materials with different external dimensions, and can also prevent the loader from spilling materials during loading and transportation.

[0017] (2) The lower clamp of the grass grabber adopts a closed multi-tooth structure to prevent material spillage during loading and transportation by the loader;

[0018] (3) When the working device of the loader for mushroom cultivation is at any position within 3 meters above the ground at the hinge point between the boom and the grass grabber, the downward tilting angle J of the grass grabber is above 60°. Especially when the hinge point between the boom and the grass grabber is at its lowest point (when the boom cylinder is in its shortest state), the downward tilting angle J of the grass grabber can reach 67°, which meets the operation requirements of mushroom cultivation.

[0019] (4) When the loader working device is in the downward state of the grass grabbing device, the upward force of the tipping cylinder can exceed the rated load by more than 10%. Especially when the distance between the boom and the grass grabbing device hinge point is the lowest (when the boom cylinder is in the shortest state), the upward force of the tipping cylinder can exceed the rated load by 20%, which meets the operation requirements of mushroom cultivation.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the invention.

[0026] like Figure 1 As shown, a loader working device for mushroom cultivation includes a grass grabber 1, a boom 2, a tie rod 3, a rocker arm 4, a tipping cylinder 5, a boom cylinder 6, and a main unit 7.

[0027] like Figure 1As shown, the rear end of boom 2 is hinged to the main unit 7 at point I, the front end of boom 2 is hinged to the grass grabber 1 at point A, the upper middle part of boom 2 is hinged to the middle part of rocker arm 4 at point D, the lower middle part of boom 2 is hinged to the front end of boom cylinder 6 at point F, the rear end of boom cylinder 6 is hinged to the main unit 7 at point H, the front end of tie rod 3 is hinged to the grass grabber 1 at point B, the rear end of tie rod 3 is hinged to the lower end of rocker arm 4 at point C, the upper end of rocker arm 4 is hinged to the front end of tipping cylinder 5 at point E, and the rear end of tipping cylinder 5 is hinged to the main unit 7 at point G.

[0028] Point D, where the upper part of the boom 2 is hinged to the middle part of the rocker arm 4, is not located at point E, where the upper end of the rocker arm 4 is hinged to the front end of the tipping cylinder 5, and point C, where the rear end of the tie rod 3 is hinged to the lower end of the rocker arm 4.

[0029] like Figure 2 As shown, the grass grabber 1 includes: an upper clamping body, a hydraulic cylinder 12, a hinge pin 13, a lower clamping body 14, an upper pin 16, and a lower pin 17. The upper clamping body is further divided into a left upper clamping body 15 and a right upper clamping body. The upper clamping body and the lower clamping body 14 are connected by the hinge pin 13. The hydraulic cylinder 12 is connected to the upper clamping body via the upper pin 16, and to the lower clamping body 14 via the lower pin 17. The extension and retraction of the hydraulic cylinder 12 is controlled by the loader's hydraulic system, thereby controlling the opening and closing of the upper clamping bodies (left upper clamping body 15 and right upper clamping body) of the grass grabber 1 to grab materials.

[0030] like Figure 2 As shown, the upper clamp of the grass grabber 1 adopts a split multi-tooth structure, which can simultaneously grab two or more materials with different shapes and sizes, and can also prevent the loader from spilling materials during loading and transportation.

[0031] like Figure 2 As shown, the split-type multi-tooth upper clamp body includes: a left upper clamp body 15 and a right upper clamp body. Both the left upper clamp body 15 and the right upper clamp body are connected to the lower clamp body 14 through hinge pins 13. The upper ends of the two implement cylinders 12 are connected to the left upper clamp body 15 and the right upper clamp body respectively through upper pin shafts 16, and the lower ends of the two implement cylinders 12 are connected to the lower clamp body 14 through lower pin shafts 17. The upper clamp body adopts a split clamp body. The extension and retraction of the two implement cylinders 12 are controlled by the loader hydraulic system, thereby independently controlling the opening or closing of the left upper clamp body 15 and the right upper clamp body of the grass grabber to grab materials.

[0032] like Figure 2 As shown, the upper clamp body or the upper left clamp body 15 and the upper right clamp body are also provided with lever arms 18. Lever arms 18 are fixed on the upper clamp body, and one end of them extends above the hydraulic cylinder 12. The upper clamp body or the upper left clamp body 15 and the upper right clamp body are hinged to the hydraulic cylinder 12 through the lever arm 18. The setting of lever arm 18 can reduce the control force of the hydraulic cylinder 12, so that it can better control the opening and closing action of the grass grabbing machine 1.

[0033] The lower clamp 14 of the grass grabber 1 adopts a closed multi-tooth structure to prevent material spillage during loading and transportation by the loader.

[0034] like Figure 3 As shown, the working device of the loader for mushroom cultivation has optimized the dimensional proportions of the hinge points AF of the grass grabber, boom, tie rod, and rocker arm. This ensures that the downward tilting angle J of the grass grabber is above 60° at any position where the height of the hinge point A between the boom and the grass grabber is within 3 meters of the ground. In particular, when the hinge point between the boom and the grass grabber is at its lowest point (when the boom cylinder is in its shortest state), the downward tilting angle J of the grass grabber can reach 67°, meeting the operational requirements for mushroom cultivation.

[0035] The loader working device for mushroom cultivation has optimized the dimensional proportions of the AF hinge points of the grass grabber, boom, tie rod, and rocker arm. This allows the tilting force of the bucket cylinder to exceed the rated load by more than 10% when the grass grabber is tilted down. In particular, when the hinge point between the boom and the grass grabber is at its lowest point (when the boom cylinder is in its shortest position), the tilting force of the bucket cylinder can exceed the rated load by 20%, thus meeting the operational requirements of mushroom cultivation.

[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions or improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
