Peanut harvester is a harvesting machine that completes operations such as digging fruit, separating soil, spreading, picking, picking, and cleaning in the peanut harvesting process. For a long time, the cultivation, harvesting and processing of peanuts are mostly done by hand, and the labor intensity is high and the efficiency is low. During the entire peanut production process, the harvesting labor accounts for more than one-third of the whole process, and the operating cost accounts for more than 50% of the total peanut production cost. The development of peanut harvest mechanization has practical significance in reducing operating costs, improving operational efficiency, and increasing farmers' income. So how to troubleshoot and maintain the peanut harvester? This article is for readers to make an analysis.
1. Troubleshooting peanut harvester
(1) Instability of the machine The vibration of the machine may be due to the inconsistent swing of the digging shovels on both sides of the harvester, or to the machine vibration of the bezel after the collision of the digging shovel. At this time, as long as the swing of the digging shovel on both sides is adjusted, Adjusting the length of the connecting rod can solve the machine vibration problem. The connecting rod in front of the V-belt is responsible for the adjustment of the left digging shovel. The connecting rod in the middle of the two vertical shafts is responsible for the adjustment of the digging shovel on the right. When adjusting, lift the harvester off the ground and make the machinery run at idle speed. Loose the connecting rod lock nut and adjust the corresponding connecting rod. Observe the swing amplitude of the digging shovel on both sides. It is advisable to remove both sides without touching the protective plate. Until the adjustment is consistent with the swing, then tighten the nut.
(2) Bad soil removal The poor soil removal of peanuts means that the soil on peanuts after harvesting has not shaken cleanly. The reason is that the excavation shovel is too deep into the soil and the swing strength is reduced. At this time, the length of the central rod can be adjusted to increase the excavation shovel. The depth of the soil. Appropriately shortening the length of the central drawbar can solve this problem.
(3) Dropping fruits If peanuts fall in the ground, they need to be picked up one by one. Therefore, once the fruit drop is found, it needs to be solved in time. Most of the falling fruit is caused by too high excavation shovels, which can be adjusted by adjusting the central rod. Contrary to the poor soil removal methods, extending the length of the center pull rod can solve the problem of falling fruit.
2. Maintenance of peanut harvester
Peanut harvester's meticulous maintenance is an effective way to increase machine utilization and extend the life of the machine.
(1) Maintenance after shift operations After the class is finished, the peanut harvester shall remove the dirt from the harvester parts to prevent the implements from rusting, and then open the hood to remove the weeds entangled on each part.
(2) Maintenance after one week of use After the peanut harvester is used for one week, grease shall be added to joints and bearings, and other lubrication points shall be inspected and supplemented. Check the wear of the peanut harvester belt and replace it if worn.
(3) Maintenance after each quarter of work After all the quarterly operations have been completed, not only should the machine be completely cleaned, but the triangle belt should be relaxed. After the bearing inspection of each operating part is replaced, add enough butter.
(4) Maintenance during storage The peanut harvester should select the place for ventilation and shading during storage. Raise the rack with bricks or other items to make the excavating shovel and the depth wheel away from the ground. Finally, use a plastic cloth to cover the peanut harvester. live.
