Self-propelled tomato harvester

Abstract

The invention relates to an agricultural machine, in particular to a self-propelled tomato harvester. The self-propelled tomato harvester comprises a rack and a feeding cutting table, the feeding cutting table is arranged at the front end of the rack, the harvester further comprises a conveying device and a picking device, the picking device is arranged at the rear end of the rack, the conveying device is arranged between the feeding cutting table and the picking device, the feeding cutting table, the conveying device and a picking separating device are all connected with the rack, and the feeding cutting table is connected with the rack through a lifting system; the feeding cutting table comprises a cutting table rack, a picking device, tooth shape opposite cutters and a grid pull-over, the picking device comprises a pair of harvesting clamps and a gear and rack transmission mechanism connected with the two harvesting clamps, the lower portions of the back portions of the two harvesting clamps are each provided with one tooth shape opposite cutter, and the grid pull-over is located above the rear portions of the harvesting clamps. The harvester is small in size and floor area andcan meet the requirement for harvesting tomatoes of the Sinkiang variety.

Description

technical field [0001] The invention relates to agricultural machinery, in particular to a self-propelled tomato harvester. Background technique [0002] Xinjiang is rich in water and soil resources, which provides favorable conditions for the growth of Xinjiang tomatoes. The fruit has the characteristics of bright color, less pests and diseases, less cracking, rich nutrition and large fruit. It has obvious advantages in the competition of similar products in the international market. Known as China's red industrial belt. With the increasing scale of tomato planting, traditional manual picking is gradually eliminated due to insufficient labor force and high cost. At present, mechanical picking is usually used. But there are following defects in existing mechanical picking: [0003] 1. There are defects in the traditional fruit seedling separation mechanism [0004] The driven comb type separation mechanism is when the machine walks along the ridge, the comb teeth are inse...

AI Technical Summary

Problems solved by technology

[0005] The drum type separation device is to transfer the fruit and fruit seedlings to the separation drum, and realize multiple ups and downs on the tomato fruit seedlings, so that the fruits fall off, but if the speed is too slow during this process, the separation will be incomplete. If it is too fast, the fruit will not have time to fall, and will be discarded together with the seedlings, resulting in harvest loss;

[0006] The fruit picking and separating device is to pull out the fruit first, and then knock the fruit on the conveyor belt to make the fruit fall. However, after separation, the seedlings must be removed from the conveyor belt. The process is cumbersome and does not meet the requirements of high-efficiency operations.

[0007] 2. The existing tomato harvester cannot adapt to the movement and work on the road and in the field at the same time because the chassis of the front working device is too low

[0008] 3. The existing device for separating plants from the ground only has the function of provoking and falling back, and does not have the function of gathering in the middle, which makes the work of the cutter relatively large and inconvenient for operation

[0009] 4. The plant height of Xinjiang tomato is higher than that of ordinary tomato, the stalk is thick, and the tomato grows in clusters and is relatively concentrated. It is difficult to completely harvest the fruit through the existing methods of harvesting ordinary tomatoes such as beating and rolling. And it is easy to damage the fruit and cause harvest loss due to incomplete separation of fruit seedlings
