Description

Technical Field

[0001] This utility model belongs to the field of agricultural machinery, specifically relating to a large-format straw bale press and release device. Background Technology

[0002] Large-format hay balers are one of the important pieces of equipment in my country's agricultural and pastoral harvesting machinery. Their main function is to collect, convey, feed, compress, and bale loose hay, rice straw, wheat straw, and other crops into high-density rectangular bales. The use of a bale release device effectively ensures a smooth transition of the bales from the large-format hay baler to the ground, preventing them from scattering due to falls. Existing bale release devices mostly adopt a plate structure, which suffers from high release resistance, inconvenient bale weighing, and inability to meet the needs of bale release for different lengths, thus affecting the operating efficiency of large-format hay balers. Summary of the Invention

[0003] To overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a baling device with low baling resistance, convenient bale weighing, and suitable for baling operations of bales of different lengths.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] A large-format straw bale baler unloading device includes a corner frame, a hydraulic cylinder bracket, a sensor bracket, a roller support, a conveyor roller, a connecting plate, a load cell, a connecting pipe, fasteners, a folded edge, a roller support, and a chain. The corner frame is characterized by: a hydraulic cylinder bracket fixed to its bottom; sensor brackets symmetrically fixed externally; and roller supports symmetrically fixed internally. The roller supports are fixed to freely rotatable conveyor rollers. The upper end of the sensor bracket is hinged to the connecting plate, and the lower end is designed with a connecting pipe for installing load cells. The load cells are inserted into the connecting pipe of the sensor bracket and fixed by fasteners. The bottom of the corner frame has an inwardly folded edge, and the roller support is placed on the folded edge at the bottom of the corner frame and fixedly connected to the corner frame by fasteners. Five freely rotatable conveyor rollers are fixed inside the roller support, and chains are symmetrically fixed externally. The chains are connected to the upper end of the sensor bracket.

[0006] The beneficial effects of this utility model are: the roller bracket and roller support are fixed with freely rotating conveyor rollers, which reduces the friction force on the bales when they slide on the unloading device, and reduces the unloading resistance of the Dafang bale press; the weighing sensor is inserted into the connecting pipe at the lower end of the sensor support, which can accurately and conveniently weigh the continuously output bales; the installation position of the roller support on the bottom folded edge of the corner frame can be adjusted according to the length of the bales, realizing the unloading operation of bales of different lengths of the Dafang bale press.
