Description

Technical Field

[0001] The utility model relates to the field of harvesting, in particular to the technical field of silage harvesting, and specifically refers to a silage harvester. Background Art

[0002] Silage is a type of feed that is made from plant-based feeds with high moisture content through sealing and fermentation, and is mainly used to feed ruminants. Silage is more storage-resistant than fresh feed, and its nutritional components are stronger than those of dry feed. In addition, silage storage occupies less land and there is no fire problem.

[0003] Silage is obtained by cutting green forage with a moisture content of 65% - 75% into pieces and then, under anaerobic and oxygen-deficient conditions, inhibiting the reproduction of various miscellaneous bacteria through the fermentation of anaerobic lactic acid bacteria. Silage has an acid fragrance, is soft and juicy, has good palatability, is rich in nutrition, and is conducive to long-term preservation, making it an excellent feed source for livestock.

[0004] When harvesting silage, the driver drives the harvester to move. The silage material is cut by the cutter and enters the crusher through the conveying trough for crushing. Finally, the feed is transported into the discharge box. Since the height of the discharge box is relatively high, a conveying mechanism is added between the crusher and the discharge box for transportation, which increases the length of the entire equipment and also increases the cost. Content of the Utility Model

[0005] In view of the deficiencies of the prior art, the utility model provides a silage harvester. Through the settings of a feeding bin, a feeding plate, and a feeding pipe, the silage material is thrown upward and fed into the discharge bin, thereby shortening the length of the entire equipment and reducing the cost.

[0006] The utility model is realized through the following technical solutions. A silage harvester includes a vehicle body and a crushing and shredding device located between the discharge box and the conveying trough. The crushing and shredding device includes a box body, which includes a chopping bin communicating with the conveying trough, a crushing bin located behind the chopping bin, and a feeding bin located on the side of the crushing bin and having a feeding opening on the top surface. A plurality of feeding plates for driving the silage material to be discharged from the feeding opening are arranged in the feeding bin. A feeding pipe extending upward and having a first arc surface on the front side is also connected to the feeding opening, and the first arc surface protrudes forward.

[0007] When the utility model is in use, the silage material is cut by the cutter and enters the chopping bin, the crushing bin, and then the feeding bin through the conveying trough and the feeding opening in sequence. Driven by the feeding plates, the silage material is thrown upward, passes through the feeding opening, and is fed into the discharge bin along the feeding pipe, thereby shortening the length of the entire equipment and reducing the cost.

[0008] Preferably, a feeding shaft is axially connected inside the feeding bin, and a plurality of the feeding plates are arranged on the circumferential surface of the feeding shaft. The inner bottom surface of the feeding bin is a second arc surface adapted to the rotation radius of the feeding plate.

[0009] In this preferred solution, through the arrangement of the feeding shaft, the edge drives the feeding plate to rotate, so as to realize the feeding plate pushing the silage material to be thrown upwards; at the same time, the inner bottom surface of the feeding plate is arranged as a second arc surface, which facilitates the feeding plate to drive the silage material to rotate and also reduces the residue of the silage material in the feeding bin.

[0010] Preferably, the crushing cutters fixed on the crushing shaft in the crushing bin are all inclined towards the feeding bin. In this preferred solution, through the inclined arrangement of the crushing cutters, a guiding effect is given to the silage material entering the feeding bin.

[0011] Preferably, the end face of the feeding plate away from the feeding shaft is serrated. This preferred solution facilitates the feeding plate to fully drive more materials to rotate along with the feeding plate.

[0012] Preferably, the feeding shaft and the crushing shaft are coaxially arranged and connected. This preferred solution is arranged to facilitate the simultaneous rotation of the crushing shaft and the feeding shaft, thus avoiding the situation of the feeding shaft idling when there is no material.

[0013] Preferably, the feeding shaft is connected to the chopping shaft in the chopping bin through a belt pulley, and the crushing shaft is connected to the motor on the vehicle body through a belt pulley.

[0014] This preferred solution drives the chopping shaft, the crushing shaft, and the feeding shaft to rotate simultaneously by one motor, optimizing the setting of the driving power and also optimizing the device setting on the vehicle body.

[0015] The beneficial effects of the present utility model are as follows: The silage material is harvested by the cutter, enters the chopping bin, the crushing bin, and then the feeding bin in sequence through the conveying trough and passing through the feeding port. Driven by the feeding plate, the silage material is thrown upwards and passes through the feeding port along the feeding pipe and is sent into the discharging bin, thus shortening the length of the entire equipment and reducing the cost; through the arrangement of the feeding shaft, the edge drives the feeding plate to rotate, so as to realize the feeding plate pushing the silage material to be thrown upwards; at the same time, the inner bottom surface of the feeding bin is arranged as a second arc surface, which facilitates the feeding plate to drive the silage material to rotate and also reduces the residue of the silage material in the feeding bin; through the inclined arrangement of the crushing cutters, a guiding effect is given to the silage material entering the feeding bin.
