Description

Technical Field

[0001] This utility model relates to the field of baling machine technology, and in particular to a folding mechanism for a baling machine with a rotating screen. Background Technology

[0002] A baler is an agricultural machine used to compress and bundle loose materials such as straw and hay into bales. It is widely used in agricultural production and animal husbandry. A baler is a mechanical device used for bundling, compressing, and sealing goods. It can bundle loose items into compact packages, improving transportation efficiency and reducing losses. Balers are mainly divided into two types: manual balers and automatic balers. Automatic balers use electro-hydraulic pressure transmission technology, which can complete the baling task faster and more accurately. Depending on the application, balers can be divided into various types, such as hydraulic balers, tractor-trailer balers, corn stalk balers, wheat straw balers, rice straw balers, flax balers, etc. The dust removal device of the baler is fixedly installed with fasteners. The installation position of the dust removal device is at the highest point. When passing through culverts or height-restricted sections, the dust removal screen can only be removed to pass or detour, which is not only inconvenient but also increases transportation costs. Utility Model Content

[0003] The purpose of this invention is to address the aforementioned problems and shortcomings by proposing a rotating screen folding mechanism for a baler: Hydraulic cylinder three retracts, pulling hydraulic cylinders one and two to rotate. At this time, the rotating screen dust removal device rotates to the top of the support rod and crossbar via rotating blocks one and rotating shafts one and two on hydraulic cylinders one and two. This facilitates placement, bending, reducing the overall height, and transportation. It solves the problem of excessive height hindering transportation.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A folding mechanism for a baler includes a base plate, a hopper mounted on the top outer wall of the base plate, and a folding structure mounted on the top outer wall of the base plate at the hopper. A dust removal device for the folding structure is mounted on the top of the hopper, and a support assembly is provided on one end of the outer wall of the base plate. The folding structure includes a support frame mounted on the top outer wall of the base plate, support inclined plates welded to both ends of the top outer wall of the support frame, a rotating shaft I welded to the outer walls of both ends of one side of the support inclined plates, hydraulic cylinder I and hydraulic cylinder II respectively located at the rotating shaft I, and rotating blocks I mounted at both ends of hydraulic cylinder I and hydraulic cylinder II.

[0005] Preferably, a rotating shaft 2 is provided at one end of the rotating block of the first hydraulic cylinder and the second hydraulic cylinder, and an installation ring is welded to the other end of the rotating shaft 2. The rotating screen dust removal device is installed on the inner side outer wall of the installation ring, and the two ends of the first hydraulic cylinder and the second hydraulic cylinder are rotatably connected to the outer wall of the first rotating shaft and the second rotating shaft through the rotating block 1.

[0006] Preferably, an extension plate is installed at one end of each of the two outer walls of the support frame, and a pull ring is installed at the top of the outer wall of the hydraulic cylinder, with the pull ring and one end of the extension plate close to each other and a rotating shaft on one side of the outer wall.

[0007] Preferably, a hydraulic cylinder is provided between the three rotating shafts, and rotating blocks are installed at both ends of the hydraulic cylinder, and the rotating blocks are rotatably connected to the outer wall of the three rotating shafts.

[0008] Preferably, a limiting plate is installed on the outer wall of the hopper at the location of the second hydraulic cylinder, and one side of the outer wall of the second hydraulic cylinder is in contact with the outer wall of the limiting plate. The first hydraulic cylinder is parallel to the second hydraulic cylinder, and the second hydraulic cylinder is higher than the first hydraulic cylinder.

[0009] Preferably, the support assembly includes a hinged seat installed at one end of both sides of the support frame, a support rod rotatably connected to the outer wall of the hinged seat, and crossbars installed at equal intervals on the top outer wall of the support rod.

[0010] Preferably, the hydraulic cylinders three, two, and one are connected to the controller via wires, and the controller is connected to the power supply via wires. A reinforcing rod is installed on the support frame at the support inclined plate.

[0011] The beneficial effects of this utility model are as follows: When hydraulic cylinder three retracts, it pulls hydraulic cylinder one and hydraulic cylinder two to rotate. At this time, the rotary screen dust removal device rotates to the top of the support rod and crossbar through the rotating block one and rotating shaft one and rotating shaft two on hydraulic cylinder one and hydraulic cylinder two. This makes it easy to place, easy to bend, easy to reduce the overall height, and easy to transport. Unfold the support rod on the hinge seat, and lay the crossbar on top of the support rod to facilitate the placement of the rotary screen dust removal device. Attached Figure Description
