Example Embodiment

[0038] The present invention will be further described in detail below in conjunction with the drawings.

[0039] The stepwise compaction method of alfalfa fresh grass scraps is as follows:

[0040] 1. Set the compaction parameters: the compaction barrel is placed at the starting position of the highest point of the lifting device. According to the alfalfa silage process requirements, set the critical pressure value of the response signal sent by the pressure sensor and the working time of one unloading stroke of the unloading hydraulic motor; Set the gravity compensation value of the compacted material according to the preset compaction density to offset the influence of the gravity of the compacted material on the compaction density;

[0041] 2. Segmented compaction: use auger to transport and squeeze the fresh alfalfa grass to the compaction bucket;

[0042] 3. Unloading and compaction cycle: When the fresh grass scraps in the barrel reach the preset pressure, the signal processing...

Abstract

The invention relates to a staged compacting method and device for crushed fresh alfalfa forage. The staged compacting method comprises the following steps: firstly, parameters are preset, then a compacting process for the crushed fresh alfalfa forage is performed by stages, and through the coordination of a vertical staged auger and an unloading hydraulic motor, compacting and unloading work circulates. The device comprises a material bin, an unloading cylinder, the auger, a compacting barrel, a lifting mechanism, the unloading hydraulic motor, a pressure sensor and a signal processing control system, and hydraulic and communication control systems are used for ensuring that the compactness intensity of the crushed fresh alfalfa forage in all stages meets the requirements of an alfalfa silage process and the intensity is constant. According to the method and the device, nutrient loss caused to fresh alfalfa forage during a mechanical compaction process can be reduced, the compacting is even, the intensity is adjustable, and the operation is continuous and stable.

Description

technical field [0001] The invention relates to a method and device for compacting fresh grass scraps, in particular to a segmental compaction method and device for fresh grass scraps of alfalfa, belonging to the field of animal husbandry machinery. Background technique [0002] Alfalfa has the advantages of high crude protein content, good palatability, easy digestion, and low crude fiber content, and is currently the main source of high-quality feed for animal husbandry. The harvest season of alfalfa in the main alfalfa producing areas in my country is mostly the rainy season, and the nutrient loss can reach up to 50%, which is not suitable for harvesting alfalfa hay. The silage production of alfalfa can effectively preserve the nutritional content of alfalfa and facilitate long-term storage. Therefore, alfalfa silage technology is being gradually popularized and applied in recent years. [0003] Alfalfa silage to achieve a suitable compaction density is the key process ...
