Description

Technical Field

[0001] The utility model relates to the technical field of agricultural and animal husbandry machinery, in particular to a foldable transverse grass rake. Background Art

[0002] Alfalfa has strong adaptability and is tolerant to alkaline soil but not acidic soil. It is suitable for growing in neutral soil with good drainage, deep soil layer and rich in calcium. It has a relatively fast growth rate and can quickly cover the soil under suitable conditions. Alfalfa can symbiotically fix nitrogen with rhizobia, increase soil fertility, and play multiple roles in agriculture, animal husbandry and ecological construction.

[0003] When harvesting alfalfa, the rake gathers the scattered grass into strips, increasing the area of contact between the grass and the air, thereby accelerating the evaporation of moisture in the grass and allowing the grass to dry more quickly to a moisture content suitable for storage.

[0004] Application number: CN202021622330.1 discloses a hydraulically-lifted horizontal grass rake, comprising a frame, a grass rake, a wheel axle, a leg jack, an intermediate beam, a left-hand angle steel (I), a left-hand angle steel, a crossbeam, a traction plate, a pin, an adjustable square tube device, an oil pipe, a right-hand angle steel, and a right-hand angle steel (I). The hydraulically-lifted horizontal grass rake provided by this utility model features a rational structural design, convenient operation, and ease of maintenance and repair. It offers excellent performance and high productivity. When the rake teeth are harvesting forage, the operation can be completed by simply moving the tractor's hydraulic handle back and forth. When the tractor's hydraulic handle is moved to the raised position, the hydraulic cylinder provides power to lift the rake teeth beam. When the tractor's hydraulic handle is moved to the lowered position, the rake rapidly descends to the rake position under its own weight. After the operation is completed, the machine can be switched from the working state to the transport state with a simple operation, effectively meeting the needs of practical applications.

[0005] However, the above device has the following problems when used: the grass-raking mechanism cannot be retracted, takes up a large space when idle, is inconvenient to load and unload, and is inconvenient to move. At the same time, the above device is not convenient for adjusting the working width of the grass-raking mechanism. Therefore, a foldable horizontal grass-raking machine is needed. Utility Model Content

[0006] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a foldable horizontal grass rake.

[0007] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0008] A foldable horizontal grass rake comprises a connecting rod, a C-shaped mounting frame being rotatably mounted on the end of the connecting rod, a mounting block being rotatably mounted within the C-shaped mounting frame, a centralizing disk being fixedly mounted on the top and bottom ends of the mounting block, a pair of grass rake assemblies being symmetrically arranged between a pair of the centralizing disks, and a drive assembly for adjusting the angle of the grass rake assemblies being disposed within the pair of the centralizing disks;

[0009] The grass raking assembly includes a pair of rotating rods rotatably installed between a pair of centralizing disks, a rotating block is fixedly sleeved on the pair of rotating rods, a grass raking mounting plate is fixedly installed on the end of the rotating block, a movable mounting plate is movably provided below the grass raking mounting plate, a plurality of connecting plates are fixedly installed on the bottom end of the movable mounting plate, a grass raking rake is fixedly installed on the front end of the connecting plate, and a plurality of supporting components are provided at the bottom end of the rotating block.

[0010] Preferably, a telescopic cylinder is fixedly installed on the top of the grass raking mounting plate, and the telescopic rod of the telescopic cylinder movably passes through the grass raking mounting plate and is fixedly installed on the top of the movable mounting plate. A plurality of sliding rods are fixedly installed on the top of the movable mounting plate, and the sliding rods slide and pass through the top of the grass raking mounting plate. A limit block is fixedly installed on the top of the sliding rod;

[0011] It is used for raking grass operations. The telescopic cylinder pushes the movable mounting plate through the telescopic rod, so that the lower end of the connecting plate is close to the ground, thereby facilitating the raking and raking grass operations.

[0012] Preferably, the support assembly comprises a plurality of support columns equidistantly and evenly fixedly mounted on the bottom end of the rotating block, the bottom end of each support column is rotatably mounted with a rotating ball, and the outer wall of the rotating ball is in contact with the outer wall of the centralizing disk;

[0013] It is used to ensure the stability of the rotating block and the raking mounting plate during rotation. When the rotating rod drives the rotating block and the raking mounting plate to rotate, the rotating ball rotates at the bottom end of the support column, providing support while increasing the smoothness of rotation.

[0014] Preferably, the driving assembly includes a rotating shaft rotatably mounted between a pair of concentrating disks, the rotating shaft being coaxially fixedly connected to a driving gear, the driving gear being meshed with a pair of driven gears, the driven gears being coaxially fixedly connected to a rotating rod, a forward and reverse motor being fixedly mounted on the top of the concentrating disk, and an output shaft of the forward and reverse motor being coaxially fixedly connected to the rotating shaft;

[0015] It is used to rotate the mowing assembly, adjust the operating width of the mowing assembly and fold a pair of mowing assemblies at the same time, which is convenient for loading, unloading and moving. The forward and reverse motors drive the driving gear to rotate forward through the rotating shaft, and the driven gear drives the rotating rod to rotate. At this time, the mowing assembly moves closer to the connecting rod to adjust the operating width of the mowing assembly. When the mowing operation is completed, the forward and reverse motors drive the driving gear to rotate in the opposite direction through the rotating shaft. At this time, the mowing assembly moves away from the connecting rod, and finally makes the outer walls of a pair of mowing mounting plates fit together, which is convenient for subsequent loading, unloading and moving.

[0016] Preferably, a support wheel is fixedly installed at the bottom end of the centralizing disk, and a universal wheel is fixedly installed at one end of the bottom of the grass raking mounting plate away from the centralizing disk;

[0017] The supporting wheel and the bottom end of the universal wheel are located at the same height.

[0018] The utility model has the following beneficial effects:

[0019] 1. By setting up a driving assembly, the forward and reverse motors drive the driving gear to rotate forward through the rotating shaft, and the driven gear drives the rotating rod to rotate. At this time, the raking assembly moves closer to the connecting rod to adjust the operating width of the raking assembly. When the raking operation is completed, the forward and reverse motors drive the driving gear to rotate in the opposite direction through the rotating shaft. At this time, the raking assembly moves away from the connecting rod, and finally the outer walls of a pair of raking mounting plates are fitted together, which is convenient for subsequent loading, unloading and movement.

[0020] 2. By setting up a grass raking component, the telescopic cylinder pushes the movable mounting plate through the telescopic rod, so that the lower end of the connecting plate is close to the ground, which facilitates the grass raking operation. When the rotating rod drives the rotating block and the grass raking mounting plate to rotate, the rotating ball rotates at the bottom of the support column, providing support while increasing the smoothness of the rotation.
