Description

Technical Field

[0001] This utility model belongs to the field of livestock machinery technology, specifically a parallel double-outlet square baler for efficient collection and baling of forage or crop straw. Background Technology

[0002] As a key piece of equipment for harvesting forage and crop straw, the core function of a square baler is to compress field materials into high-density square bales to improve transportation and storage efficiency. Traditional single-output square balers employ a single-piston reciprocating compression and single knotter operation mode, which suffers from inherent bottlenecks such as intermittent compression and limited operating efficiency. To overcome these limitations, this invention provides a novel square baler structure with continuous compression capability and efficient dual-baler coordinated output. Reducing the complexity of the implement structure while ensuring synchronous dual-baler output, and designing an anti-interference dual-baling mechanism to improve the reliability and operating efficiency of the implement structure, has become a pressing technical challenge in this field. Utility Model Content

[0003] To overcome the shortcomings of the existing technology, this utility model provides a parallel double-outlet square baler that can efficiently pick up materials by integrating dual feeding channels, alternating phase compression piston groups, independently operating double knotter mechanisms, and double-outlet baler output devices.

[0004] This utility model is achieved through the following technical solution:

[0005] This utility model relates to a parallel double-outlet square baler, comprising a protective traction beam device, a wide-angle drive shaft, a frame assembly, a five-row flexible beam picking device, a left baling mechanism assembly, a right baling mechanism assembly, a density adjustment chamber device, a baling mechanism chain, a protective cover device, a baling plate, and a hydraulic cylinder. The traction frame assembly of the protective traction beam device is concentrically connected to the front of the frame assembly; the five-row flexible beam picking device is connected to the lower front of the frame assembly; one end of the hydraulic cylinder is hinged to the frame assembly, and the other end is hinged to the five-row flexible beam picking device; the left baling mechanism assembly is installed and fixed on the upper left of the frame assembly, and the right baling mechanism assembly is symmetrically arranged along the center line of the frame assembly on the upper right of the frame assembly; the density adjustment chamber device is connected and fixed at the rear of the frame assembly; and the baling plate is connected and fixed at the rear of the density adjustment chamber device. The bale release plate behind the density adjustment chamber is mainly used to adjust the bale release direction to adapt to different operating directions and crop harvesting needs, thereby improving operating efficiency. The five-row flexible beam picking device picks up materials more cleanly and faster, and is equipped with a hydraulic cylinder to adjust the picking height, realizing stepless adjustment of the distance between the five-row flexible beam picking device and the ground to adapt to different straw thicknesses or terrains.

[0006] As a preferred embodiment of this utility model, the protective traction beam device includes a hook-up frame assembly, a traction head weldment, a connecting traction head assembly, a traction frame assembly, a grass press assembly, and pins. The hook-up frame assembly is concentrically connected and fixed below the traction head weldment by pins. The connecting traction head assembly is concentrically connected and fixed behind the traction head weldment by two pins. The traction frame assembly is fixed behind the connecting traction head assembly. The grass press assembly is concentrically connected below the traction frame assembly. The traction head assembly has a via connecting the tractor and the wide-angle driveshaft. One end of the wide-angle driveshaft is connected to the frame assembly, and the other end is connected to the via connecting the traction head weldment. The core function of the wide-angle driveshaft is to reliably transmit tractor power to the gearbox under dynamic offset, vibration, and heavy load conditions. Without interrupting power, the protective traction beam device can reduce the turning radius during implement operation, significantly improve steering flexibility, and extend the service life of the wide-angle driveshaft, making it particularly suitable for small plots, high-density planting, or complex terrain operations. The small-radius steering capability of the protective traction beam device relies on the large deflection angle of the wide-angle driveshaft. The two work together to protect the driveshaft and ensure uninterrupted power during sharp turns.

[0007] In a preferred embodiment of this utility model, the frame assembly includes a frame body assembly, a gearbox, a left crank connecting rod piston assembly, a right crank connecting rod piston assembly, a feeding mechanism, a left protective pull rod, a right protective pull rod, a drive sprocket, a driven conical double-row sprocket, a frame drive chain, and a driven single-row sprocket. The feeding mechanism is installed inside the frame body assembly. The gearbox is installed at the front of the frame body assembly. The right output shaft of the gearbox is connected to the right crank connecting rod piston assembly. The shaft at the connecting rod end of the right crank connecting rod piston assembly is connected to the right protective pull rod. The right protective pull rod is connected to the right bundling mechanism assembly. The left output shaft of the gearbox is connected to the left crank connecting rod piston assembly. The shaft at the connecting rod end of the left crank connecting rod piston assembly is connected to the drive sprocket. The left protective pull rod is connected to the upper left of the frame body assembly. The left protective pull rod is connected to the left bundling mechanism assembly. The alternating operation of the dual pistons and the coordinated operation of the dual-channel feeding mechanism significantly improve bundling efficiency.

[0008] In a preferred embodiment of this invention, the left end of the feeding mechanism is concentrically connected to a driven conical double-row sprocket, and the right end is concentrically connected to a driven single-row sprocket; a drive sprocket is located on the upper left side of the frame assembly; the driven conical double-row sprocket is located below and behind the drive sprocket; power is transmitted by the frame drive chain. Compared to traditional sprockets, the driven conical double-row sprocket allows for quick assembly and disassembly, reducing downtime.

[0009] In a preferred embodiment of this utility model, a protective cover is installed on the outer side of the frame assembly. The protective cover includes a left rope box assembly, an electric push rod, a frame cover, and a right rope box assembly. The left rope box assembly is located on the left side of the frame cover, and the right rope box assembly is located on the right side. Electric push rods are installed below the left and right rope box assemblies, respectively. One end of each electric push rod connects to the left and right rope box assemblies, and the other end connects to the frame assembly. The rope box moves outward via the electric push rod, increasing the operating space and making maintenance more convenient compared to traditional fixed rope boxes.

[0010] In a preferred embodiment of this invention, power is transmitted from a tractor to a gearbox via a protective traction beam device and a wide-angle drive shaft. The gearbox then transmits power to the left crank connecting rod piston assembly, the right crank connecting rod piston assembly, and the drive sprocket. The drive sprocket transmits power via a frame drive chain to the driven conical double-row sprockets and driven single-row sprockets at both ends of the feeding mechanism. The driven conical double-row sprockets and driven single-row sprockets transmit power to the left and right baling mechanism assemblies via the baling mechanism chain, respectively. The feeding mechanism uses a single-sided input and dual-sided output to achieve alternating feeding. The dual baling mechanism uses dual-sided transmission, with synchronous transmission but asynchronous operation.

[0011] The present invention has the following advantages:

[0012] 1. This utility model can achieve efficient and continuous bundling by combining a double bundling mechanism with a five-row elastic beam picking device, which greatly improves work efficiency and reduces work costs. Attached Figure Description
