Description

Technical Field

[0001] This application relates to the technical field of hoisting mechanisms for agricultural machinery installation, specifically a hoisting mechanism for agricultural machinery installation. Background Technology

[0002] The main function of harvesters is to harvest crops. Mechanized harvesting can complete the harvesting of large areas of farmland in a short time, significantly improving harvesting efficiency. During the installation of agricultural machinery, regular inspections and maintenance can promptly identify and resolve problems that may arise during the use of the machinery, avoiding production interruptions caused by mechanical failures and ensuring the smooth progress of agricultural production.

[0003] The existing patent CN221917127U discloses a hoisting mechanism for repairing agricultural machinery. The mechanism involves manually starting a motor, which drives the main gear at the output end to rotate. This drives the internal gear to rotate, which in turn drives the driven gear to rotate. The driven gear then drives a threaded rod to rotate along a fixed sleeve, causing a movable plate to move along the inner side of the fixed sleeve. This movement of the movable block pushes open the elastic plate, releasing the fixing of the fixed rod. The hook is then manually removed, and the component to be hoisted is manually hung on it. The first hydraulic rod on the fixed plate is manually activated, pushing the movable sleeve to adjust its angle, thus transferring the hung component. The second hydraulic cylinder is manually activated, causing the movable rod to move within the movable sleeve, thus adjusting the height of the hung component. When the device needs to be secured, bolts are manually screwed into the bottom plate at the end of the fixed plate and pad to secure the device. Rubber pads protect the hung component, effectively preventing damage from falling parts.

[0004] When the above-mentioned device is installed on the harvester in muddy ground, it cannot be used on the uneven surface of the muddy ground. During the mechanical installation process, it will be tilted, causing safety hazards.

[0005] Therefore, it is necessary to provide a hoisting mechanism for installing agricultural machinery to solve the above problems.

[0006] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Utility Model Content

[0007] Based on the aforementioned problems in the existing technology, the problem to be solved by this application is to provide a hoisting mechanism for installing agricultural machinery, which uses a motor to drive the entire fixing frame and hook to rotate at an angle, making it easier to rotate the screw to enter the ground, and rotate the fixing feet to adjust the contact position between the fixing feet and the ground, so as to better fix it.

[0008] The technical solution adopted by this application to solve its technical problem is: a hoisting mechanism for installing agricultural machinery, including a first fixed frame, a turntable provided on the top of the first fixed frame, threaded holes provided at the four corners of the first fixed frame, a screw threadedly connected to the inside of the threaded holes, a handle fixed to the top of the screw, a fixed foot threadedly connected to the bottom of the outer side of the screw, the bottom of the outer side of the screw penetrating through the fixed foot, a fixed cylinder fixed inside the screw, a sliding column slidably connected inside the fixed cylinder, the top of the sliding column penetrating through the handle, a conical column fixed to the bottom of the sliding column, four conical grooves provided on the outer side of the conical column, four first grooves provided on the bottom of the outer side of the fixed cylinder, a locking block slidably connected inside the first groove, and a drill bit fixed to the bottom of the fixed cylinder.

[0009] The beneficial effects of the above embodiments are as follows: the conical sliding column makes the locking block better engage with the soil and prevents it from moving; by pulling the sliding column, the conical groove at the bottom of the sliding column pulls back the conical sliding column to reset it; and the conical sliding column drives the locking block to retract.

[0010] Furthermore, a groove is provided at both ends of the top of the turntable, the end of the conical slide column is slidably connected to the inside of the conical slide groove, and the conical slide column is fixed to the inside of the locking block.

[0011] The beneficial effects of the above embodiments are as follows: the sliding column is pushed, and the sliding column drives the conical column to move downward. The conical column moves downward and squeezes the conical column outward through multiple conical grooves, so that the conical column slides out through the first groove and comes into contact with the interior of the soil.

[0012] Furthermore, a motor is installed in the middle of the first fixing frame, and a rotating shaft is fixed in the middle of the turntable. The output of the motor is fixedly connected to the middle of the turntable through the rotating shaft. A fixing mechanism is provided on the top of the turntable. The fixing mechanism includes a third fixing frame. A fourth fixing frame is slidably connected to the top of the interior of the third fixing frame. A rotating blade is rotatably connected to the bottom of the third fixing frame. Support rods are rotatably connected to both ends of the other side of the third fixing frame. The bottom of the rotating blade is connected to the top of the turntable. A first hydraulic rod is rotatably connected to one side of the top of the turntable, and a second hydraulic rod is rotatably connected to one side of the third fixing frame.

[0013] The beneficial effect of the above embodiment is that by starting the motor set in the middle of the first fixing frame, the motor drives the rotating shaft to rotate, which in turn drives the turntable to rotate. The rotation of the turntable drives the fixing mechanism set at the top to rotate, thereby adjusting the position of the fixing mechanism that needs to be rotated.

[0014] Furthermore, a second sliding groove is provided in the middle of one side of the third fixing frame, the output end of the first hydraulic rod is slidably connected to the inside of the second sliding groove, and the output end of the second hydraulic rod is rotatably connected to one side of the fourth fixing frame.

[0015] The beneficial effect of the above embodiment is that: the support rod set on one side contacts the surface of the ground, so that the support rod and the fixing mechanism form a triangular structure, and the three sides of the triangle restrict each other, so that its shape is not easy to change.

[0016] Furthermore, a fixing plate is rotatably connected to the other side of the fourth fixing frame. A motor is installed at one end of the fixing plate, and an electric hoist is installed on one side of the fixing plate. The output end of the motor is connected to the electric hoist.

[0017] The beneficial effect of adopting the above embodiment is that: starting the second hydraulic rod pushes the fourth fixing frame, causing the fourth fixing frame to slide inside the third fixing frame and extend.

[0018] Furthermore, the electric hoist has a rope inside, and the output end of the rope has a hook.

[0019] The beneficial effect of adopting the above embodiment is that: starting the first hydraulic rod pushes the third fixing frame in the fixing mechanism to move, and the third fixing frame rotates through the rotating shaft, thereby adjusting the angle of the top of the third fixing frame to rotate up and down, which facilitates the adjustment of the height of the hook.

[0020] Furthermore, the first hydraulic rod is located at the top of the first slot, and the second hydraulic rod is installed at both ends on one side of the third fixing frame.

[0021] The beneficial effect of using the above embodiments is that the position of the first fixed frame can be adjusted by the first hydraulic rod and the second hydraulic rod.

[0022] The beneficial effects of this application are:

[0023] 1. This application provides a hoisting mechanism for installing agricultural machinery. By pulling the fixing mechanism to open it, and activating the first hydraulic rod to move the third fixing frame within the fixing mechanism, the third fixing frame rotates via a pivot, thereby adjusting the vertical rotation angle of its top end to facilitate hook height adjustment. Activating the second hydraulic rod pushes the fourth fixing frame, causing it to slide inside the third fixing frame and extend, thus lengthening the overall length of the fourth fixing frame and adjusting the hook's extension position within it. Activating the motor located in the middle of the first fixing frame drives the pivot, which in turn rotates a turntable. The turntable's rotation causes the top-mounted fixing mechanism to rotate, adjusting its rotation position. The mechanism can rotate without moving the entire structure. By adjusting the vertical angle, extension height, and rotation position, the hoisting mechanism for machinery installation can be used more flexibly.

[0024] Turning the handle moves the screw downwards, causing the drill bit at the bottom of the screw to penetrate the ground, making better contact between the outer side of the screw and the ground. Turning the fixing feet moves them along the screw, bringing the bottoms of the four fixing feet into contact with the ground surface, ensuring better stability and preventing tilting or movement. Pushing the sliding column moves the conical column downwards, which, through multiple conical grooves, compresses the conical column outwards, allowing it to slide out through groove number one and contact the ground. The conical column design ensures better engagement with the ground, preventing movement.

[0036] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0037] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0038] like Figure 1 , 2As shown in Figures 4, 5, and 6, this application provides a hoisting mechanism for installing agricultural machinery, comprising: a primary fixing frame 1, with threaded holes 105 at each of the four corners of the primary fixing frame 1; a screw rod 2 is threadedly connected to the inside of the threaded holes 105; a handle 201 is fixed to the top of the screw rod 2; and a fixing foot 202 is threadedly connected to the bottom of the outer side of the screw rod 2. Rotating the handle 201 causes the screw rod 2 to move downwards, allowing the drill bit 210 at the bottom of the screw rod 2 to drill into the ground, thus improving the contact between the outer side of the screw rod 2 and the ground. Rotating the fixing foot 202 causes the fixing foot 202 to move via the screw rod 2, with the bottom of the four fixing feet 202 contacting the ground surface. The bottom of the outer side of the screw rod 2 penetrates through the fixing foot 202. A fixing cylinder 203 is fixed inside the screw rod 2. The internal sliding connection of the 03 is a sliding column 205. The top of the sliding column 205 passes through the handle 201. The bottom of the sliding column 205 is fixed with a conical column 206. The outer side of the conical column 206 is provided with four conical grooves 207. The conical sliding column 209 is provided to make the locking block 208 better engage with the soil and prevent it from moving. By pulling the sliding column 205, the conical groove 207 at the bottom of the sliding column 205 pulls back the conical sliding column 209 to reset. The conical sliding column 209 drives the locking block 208 to retract. The bottom of the outer side of the fixed cylinder 203 is provided with four first grooves 204. The locking block 208 is slidably connected inside the first groove 204. The bottom of the fixed cylinder 203 is fixed with a drill bit 210. The top of the turntable 103 is provided with first grooves 104 at both ends.

[0039] A conical sliding column 209 is fixed to the inner side of the locking block 208. Pushing the sliding column 205 causes the conical column 206 to move downwards. The downward movement of the conical column 206 compresses the conical sliding column 209 outwards through multiple conical sliding grooves 207, causing the conical sliding column 209 to slide out through the first sliding groove 204 and contact the interior of the soil. The end of the conical sliding column 209 is slidably connected to the interior of the conical sliding groove 207. A motor is installed in the middle of the first fixing frame 1, and a turntable 103 is set on the top of the first fixing frame 1. A rotating shaft 102 is fixed in the middle of the turntable 103. The motor output is fixedly connected to the middle of the turntable 103 through the rotating shaft 102. A fixing mechanism 3 is set on the top of the turntable 103. By activating the first fixing frame 1... The motor installed in the part drives the rotating shaft 102 to rotate, which in turn drives the turntable 103 to rotate. The rotation of the turntable 103 drives the fixed mechanism 3 installed at the top to rotate, thereby adjusting the position of the fixed mechanism 3 to be rotated. The fixed mechanism 3 includes a third fixed frame 301. The top of the third fixed frame 301 is slidably connected to a fourth fixed frame 302. The bottom of the third fixed frame 301 is rotatably connected to a rotating page 306. Both ends of the other side of the third fixed frame 301 are rotatably connected to support rods 303. The bottom of the rotating page 306 is connected to the top of the turntable 103. One side of the top of the turntable 103 is rotatably connected to a first hydraulic rod 304. One side of the third fixed frame 301 is rotatably connected to a second hydraulic rod 305.

[0040] In this embodiment, rotating the handle 201 drives the screw 2 downward, causing the drill bit 210 at the bottom of the screw 2 to drill into the ground, making better contact between the outer side of the screw 2 and the interior of the ground. Rotating the fixing feet 202 causes the fixing feet 202 to move via the screw 2, and the bottoms of the four fixing feet 202 contact the ground surface, allowing the bottom fixing feet 202 to better stabilize the whole and prevent tilting and movement. Pushing the sliding column 205 causes the conical column 206 to move downward. The conical column 206 moves downward and squeezes the conical sliding column 209 outward through multiple conical grooves 207, causing the conical sliding column 209 to pass through the first groove 207. 04. The slide out and contacts the interior of the soil. The cone-shaped sliding column 209 makes the locking block 208 better engage with the interior of the soil to prevent it from moving. By pulling the sliding column 205, the cone-shaped sliding groove 207 at the bottom of the sliding column 205 pulls back the cone-shaped sliding column 209 to reset it. The cone-shaped sliding column 209 drives the locking block 208 to retract. By activating the motor set in the middle of the first fixing frame 1, the motor drives the rotating shaft 102 to rotate, which in turn drives the turntable 103 to rotate. The rotation of the turntable 103 drives the fixing mechanism 3 set at the top to rotate, thereby adjusting the position of the fixing mechanism 3 to be rotated. The fixing mechanism 3 can be rotated without moving the whole structure.

[0041] like Figure 1 ,2 3. A second sliding groove 307 is provided in the middle of one side of the third fixing frame 301. The output end of the first hydraulic rod 304 is slidably connected to the inside of the second sliding groove 307. The output end of the second hydraulic rod 305 is rotatably connected to one side of the fourth fixing frame 302. Through the support rod 303 provided on one side, the support rod 303 contacts the ground surface, so that the support rod 303 and the fixing mechanism 3 form a triangular structure. The three sides of the triangle are mutually constrained, and its shape is not easily changed. A fixing plate 4 is rotatably connected to the other side of the fourth fixing frame 302. Activating the second hydraulic rod 305 pushes the fourth fixing frame 302, causing the fourth fixing frame 302 to slide inside the third fixing frame 301. Extending the line, a motor 401 is installed at one end of the fixed plate 4, and an electric hoist 402 is installed on one side of the fixed plate 4. The output end of the motor 401 is connected to the electric hoist 402. A first hydraulic rod 304 is set at the top of the first slot 104, and a second hydraulic rod 305 is installed at both ends on one side of the third fixed frame 301. A rope 403 is installed inside the electric hoist 402, and a hook 404 is set at the output end of the rope 403. When the first hydraulic rod 304 is started, it pushes the third fixed frame 301 in the fixed mechanism 3 to move. The third fixed frame 301 rotates through the rotating shaft 102, thereby adjusting the angle of the top of the third fixed frame 301 to adjust the height of the hook 404.

[0042] In this embodiment, the support rod 303, in contact with the ground surface, forms a triangular structure with the fixing mechanism 3. The three sides of the triangle are mutually constrained, preventing its shape from easily changing and thus preventing serious damage such as breakage of the cylinders of the first and second hydraulic rods 305 during the use of the hook 404. Pulling the fixing mechanism 3 opens the mechanism, activating the first hydraulic rod 304 to move the third fixing frame 301 within the fixing mechanism 3. The third fixing frame 301 rotates via the pivot 102, adjusting the angle of its top rotation to facilitate height adjustment of the hook 404. Activating the second hydraulic rod 305 pushes the fourth fixing frame 302, causing it to slide and extend within the third fixing frame 301, thus lengthening the overall length of the fourth fixing frame 302 and adjusting the position of the hook 404 within it.

[0043] Working principle:

[0044] When the harvester needs to be installed in the field, the fixing mechanism 3 is opened by pulling it. Activating hydraulic rod 304 pushes the third fixing frame 301 within the fixing mechanism 3 to move. The third fixing frame 301 rotates via shaft 102, thereby adjusting the vertical rotation angle of its top end to facilitate adjustment of the hook 404's height. Activating hydraulic rod 305 pushes the fourth fixing frame 302, causing it to slide inside the third fixing frame 301 and extend, thus lengthening the overall length of the fourth fixing frame 302 and adjusting the position of the hook 404 within it to the desired extension. By starting the motor located in the middle of the first fixing frame 1, the motor drives the rotating shaft 102 to rotate, which in turn drives the turntable 103 to rotate. The rotation of the turntable 103 drives the fixing mechanism 3 located at the top to rotate, thereby adjusting the position of the fixing mechanism 3 to be rotated. The fixing mechanism 3 can be rotated without moving the whole structure. By adjusting the vertical angle, the extension height, and the rotation position, the hoisting mechanism for mechanical installation can be used more flexibly.

[0045] Rotating handle 201 causes screw 2 to move downwards, allowing the drill bit 210 at the bottom of screw 2 to drill into the ground, making better contact between the outer side of screw 2 and the ground. Rotating fixing feet 202 moves screw 2, allowing the bottoms of the four fixing feet 202 to contact the ground surface, stabilizing the entire structure and preventing tilting or movement. This pushes sliding column 205, which in turn moves conical column 206 downwards. The downward movement of conical column 206 compresses conical sliding column 209 through multiple conical grooves 207, causing it to slide out through groove 204 and contact the ground. The conical sliding column 209 allows the locking block 208 to better engage with the ground, preventing it from moving. By pulling the sliding column 205, the conical groove 207 at the bottom of the sliding column 205 pulls back the conical sliding column 209 to reset it. The conical sliding column 209 then drives the locking block 208 to retract. The support rod 303 contacts the ground surface, forming a triangular structure with the fixing mechanism 3. The three sides of the triangle are mutually constrained, making its shape less prone to change. This prevents serious damage such as the breakage of the cylinders of the first hydraulic rod 304 and the second hydraulic rod 305 during the use of the hook 404, which could cause the lifted object to fall.

[0046] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
