technical field

The invention belongs to the technical field of animal husbandry machinery, and in particular relates to a device and method for bagging crushed pasture grass silage.

Background technique

Silage forage can improve the quality of forage and the palatability of livestock, increase feed intake and production performance, and the silage forage can be preserved for a long time to solve the crisis of forage shortage in winter. The traditional silage method throws the dried and crushed forage to the trailer, and then uses the silage tower and silo cellar to fill the forage and complete the fermentation. Such silage requires a lot of manpower and material resources. The nutritional content of alfalfa is the highest in the rich production period. Since the process of making hay bales from pastures, the nutrients are lost more, and fresh pastures are not easy to preserve. The pastures can be silaged into bags, and then automatically tied up for storage and fermentation. It is convenient to take them out at the right time. Feeding can save labor cost, reduce labor intensity and facilitate feeding.

In addition to adding an appropriate amount of additives to alfalfa silage, the most important thing is to be able to compact the crushed fresh pasture to achieve a suitable density, reduce the amount of air in the silage bag, fully ferment the silage pasture, and make the pasture air Tightness is better, no air leakage.

detailed description

The present invention provides a bagging device and method for crushed pasture grass silage. The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

The structure of the device is shown in Figure 1 and Figure 2. The top of frame 25 is provided with feed bin 18, and pasture is installed in feed bin 18 and pushes auger 29, and the bottom of feed bin 18 is provided with cylindrical discharge port, and two clamping bag cylinders 6 and 22 are set on frame 25, and silage The bag 3 is clamped at the discharge port, and the feed bin 18 is connected with the throwing tube 21 at the same time.

A four-bar mechanism 12 is set in the feed bin 18, and hinged connection is adopted between its four bars; the left and right ends of the four-bar mechanism 12 are respectively hinged with the compression piston cylinders 11, 19 installed on the frame 25; The center of compression piston 20 is hinged, and the two ends of compression piston 20 are provided with compression piston roller 9 respectively, and described compression piston roller 9 cooperates with two compression piston guide rails 10 that are vertically installed in feed bin 18; The upper end is hinged with the adjustment spring 14, and a guide rail 15 is arranged on both sides of the adjustment spring 14, and the adjustment spring 14 cooperates with the guide rail 15 through the roller 13; an upper end cover 16 is installed on the top of the two guide rails 15, and the center position of the upper end cover 16 is installed and adjusted Bolt 17.

A rack guide rail 7 with a rack 28 is installed on one side of the discharge port of the bin 18 , the cutting knife 27 is meshed with the rack 28 through a gear, and the gear is driven by a hydraulic motor 26 .

An air extractor 8 is installed on the frame 25, and the air pipe 4 and the air extraction gun 5 connected with the air extractor 8 are set. The bottom of frame 25 is provided with supporting plate 1, and the two ends of supporting plate 1 are connected with two support bag cylinders 2 and 23 that are vertically installed on the frame 25 respectively;

The specific implementation steps are as follows:

The crushed pasture is thrown into the feed bin 18 through the throwing cylinder 21 under the action of the throwing fan. Under the control of the control system, the compression piston cylinders 11 and 19 work at the same time to push the four-bar mechanism 12 to move, and the four-bar mechanism 12 The upper and lower ends respectively push the adjustment spring 14 and the compression piston 20 to move, and the movement directions of the adjustment spring 14 and the compression piston 20 are opposite, and the strokes are the same. When the adjustment spring 14 hits the adjustment bolt 17, the adjustment spring 14 is compressed to a certain extent and stops moving, and the compression piston 20 also stops moving at the same time, and the cylinder is quickly withdrawn to realize a compression stroke. The stroke of the compression piston 20 is adjusted by adjusting the adjusting bolt 17, so as to adjust the compression density.

Before the crushed pasture is compressed, the hydraulic motor 26 drives the cutting knife 27 to block the outlet, so that the movement of the compression piston 20 in the silo can compact the compressed crushed pasture. After the compression is in place, the hydraulic motor 26 moves in the opposite direction , the discharge port is opened, and under the continued compression of the compression piston 20, the grass is gradually pushed out of the discharge port. At this time, the hydraulic motor 26 drives the cutting knife 27 to move forward to cut the compressed grass block, and then passes through the upper part once. Circulation, the lower grass slices are squeezed out of the discharge port by the upper grass blocks.

After the forage slices are filled with the silage bag 3, the air suction gun 5 is put into the silage bag 3 filled with silage grass, and the air pump 8 is started to extract the air in the silage bag 3, which can increase the density at the same time. Silage works better. Utilize the aluminum pinning mouth machine again to tie up the silage bag, the bag holder cylinder 2,23 moves downward, the silage bag 3 is sent out by the supporting plate 1, and the silage bag 3 full of pasture grass is released by pushing away the bag cylinder 24 effects.

The operator covers the empty silage bag at the discharge port again, and the bag clamping cylinders 6, 21 clamp the silage bag 3, and then carry out the above-mentioned work cycle.
