Cutting length the fodders of green stalks by drum chopper

Abstract

In Uzbekistan, special attention is paid to the development of livestock, poultry, and fish farming. In the ration of animals, green fodder obtained by cutting green stalks corn, alfalfa and other feed crops have a special place. For high-quality chopping of stalks with the required cutting length for each type of animal, a chopper has been developed with a simple design for chopping green feed. Testing of the chopper work, carried out at an engine speed of 2800 rpm, a cutting drum rotation speed of 950 rpm and in two rotations of the feed rollers 10 rpm and 20 rpm with an average length of alfalfa stalks 71.6 cm and an average length of corn stalks 216.4 cm, showed that at a feed roller rotation speed of 10 rpm the average cutting length of the stalks was 10.6 mm, and at a feed roller rotation speed of 20 rpm - 17.6 mm. It can be seen from the data that with a twice increase in the feed roll speed, the cutting length increases 1.66 times, which confirms the theoretical assumptions obtained.

Poultry analysis and research on the preparation of crushed blue grass feed for poultry

“…Taking this into account, a device with a compact version of a light construction was developed for grinding green grass for poultry (Figure 1) [4,12]. In the developed device, the process of grinding green grass is carried out as follows: the green grass to be ground is transferred to the feeders 2 and 9 with the help of rod 1.…”

“…Poultry is an integral part of the biological system, domestic poultry is mainly raised for meat and eggs for humans. In Uzbekistan, poultry farming is considered as one of the areas of animal husbandry to employ people and increase the population's income [1][2][3][4][5]. If we look at the past times, raising chickens, ducks and geese in households has been one of the important jobs in Asia and Europe for several thousand years.…”

Design of Mini Grass Chopper Machine as a Solution to The Problem of Goat Food Resistance in Micro-scale Farm

“…It is also a decision-making process. Decisions sometimes have to be made with too little information, sometimes with the right amount of information, or with an excess of partially contradictory information [7]. The process of designing this mini chopper uses a flow diagram as shown in figure 1.…”

Method for modeling the process of wear of gear teeth

“…Modern mechanisms and machines contain many moving interfaces, a large proportion of which are gears. This type of mechanical interface is used in almost all areas of agricultural machinery: tractors, harvester combines [1][2][3][4][5], seeders [6], grain cleaning machines [7][8][9], choppers, grinders and others [10][11][12][13][14].…”
