AI Technical Summary
The existing tomato seedlings are unable to effectively push the seedlings when the seedlings are dense, resulting in poor walking passage of the harvester, and the tomatoes are likely to fall during the seedlings, which requires manual cleaning.
The running ring chain belt is used as the push mechanism to push the seedlings and continuously transport them to the rear, so that the seedlings are effectively pushed open and sent to the rear ridge to avoid rebounding. At the same time, a power distribution gear box and hydraulic pump system drive chain-leafing mechanism was designed, and a pointed tip and a circular knife saw blade were installed at the front end of the seedling machine to deal with seedling vegetables and weeds.
It has achieved effective pushing of seedlings when the seedlings are dense, forming a channel suitable for harvester walking, reducing the drop of tomatoes, improving the efficiency of seedlings, and reducing the need for manual cleaning.

Abstract
Description
Technical Field
[0001] The invention relates to a machine for turning tomato vines. Background Art
[0002] Currently, large tomato harvesters are used to harvest tomatoes, which greatly improves the harvesting efficiency. However, before the harvest season arrives, the tomato vines have already covered the ground, and the vines on the harvester's walking path need to be turned over to the ridges to prevent the harvester from crushing the vines and tomato fruits on the path. In the past, manual work was used to harvest and turn the vines on the harvester's walking path over the ridges, which was labor-intensive and time-consuming. Now it is difficult for growers to find workers to turn the vines in time during the harvest season. Even if workers are found, their wages are higher year by year, which affects tomato planting and the economic income of farmers.
[0003] In recent years, many people have tried to make rice-turning machines to achieve mechanization of rice-turning operations. I have come into contact with several agricultural machinery manufacturers who have developed rice-turning machines, but none of them have been successful after several years of trials. Some people have also applied for relevant patents, such as a tomato rice-turning machine applied for by Xu Weimin et al. on May 28, 2011, with patent number CN20112017702.3; a tomato rice-turning machine applied for by Zhao Long, Gu Jun et al. on July 7, 2011, with patent number CN104718856B. The tomato rice-turning machines designed and manufactured by me have all been equipped with a triangular wedge-shaped head at the front end that goes deep under the rice vines, and then the symmetrical inclined push devices on both sides push the rice vines away to form a channel for the walking wheels of the harvester to travel, so as to avoid crushing the tomatoes.
[0004] This simple type of vine turning machine can barely push out a lane in areas where tomato vines are sparse, but before the tomato vines are harvested, the vines are already dense in most areas, and the pushed out vines bounce back after the vine turning machine passes, and it is impossible to form a passage suitable for the harvester to walk. This is a common problem of this type of tomato vine turning machine, so this type of tomato vine turning machine has not been popularized and applied for many years. At the same time, the tomatoes are ripe before harvesting, and many tomatoes will fall during the vine turning process. After turning the vines, there will be many fallen fruits on the passage, which need to be picked up manually. Summary of the invention
[0005] In order to solve the above technical problems, the present invention adopts a running ring chain belt as a pushing mechanism to push the vines out and continuously transport them to the rear, so that the vines are pushed out and the front half of the vines are sent to the rear ridge and will not bounce back and be laid on the pushed-open lane.
[0006] The rice seedling turning mechanism is suspended in front of the tractor with a crossbeam. There is a set of rice seedling turning machines with the same structure in front of the left and right front wheels of the tractor, turning out a lane on the left and right respectively. Each rice seedling turning machine is composed of two symmetrical chain belt rice seedling turning mechanisms. The chain belt of the chain belt rice seedling turning mechanism is supported by the support wheel and driven by the hydraulic motor. The chain belt keeps moving, pushing the rice seedlings attached to the chain belt to one side and continuing to send them to the rear.
[0007] Two identical rice turning machines are hung symmetrically on the left and right sides. Each rice turning machine turns out a lane. Each rice turning machine has a pointed tip at the front end, which picks up the rice vines crawling on the ground. As the tractor pushes the rice turning machine forward, the rice vines are piled up continuously. When the piled rice vines are close to the chain belt of the rice turning machine, they are pushed to one side by the chain belt. As the machine continues to move, the rice vines are sent to the rear by the constantly moving chain belt. The rice vines are like being turned to one side manually, rather than being pushed to one side, so the rice vines will not bounce back and be laid on the lane again.
[0008] The two sets of rice turning machines have four chain belt rice turning mechanisms, each of which is driven by a hydraulic motor. The present invention designs a power distribution gear box installed on the rear output shaft of the tractor and driven by the rear output shaft of the tractor. The power distribution gear box has two spline holes connected to the spline shaft of the hydraulic pump, which can drive two triple hydraulic pumps, and each hydraulic pump drives a hydraulic motor of a chain belt rice turning mechanism.
[0009] There is a fallen fruit cleaning brush behind each set of vine turning mechanism, which sweeps the fallen fruits on the driveway to the edge of the vines, and can be collected into the picking machine together with the tomato samples when picking.
[0010] A circular saw blade is installed just above the pointed end to cut off the entangled vines or weeds, so that the vine turning machine can move forward without pulling the vines. Description of the drawings:
