Description

Picking table of melon harvester

technical field

The invention relates to a picking platform of a melon harvester, which belongs to the technical field of agricultural machinery.

Background technique

Watermelon (also known as watermelon for seeds) is a variety of watermelon. The fruit is smaller than watermelon, and the seeds are many and large. It is mainly used to produce edible watermelon seeds. Due to its low requirements on the growth environment, simple planting mode, drought resistance, low input cost, and high economic benefits, melon is mostly distributed in arid barren land and saline-alkaline dry land, and is one of the important economic crops for farmers to increase income.

At present, the melon harvesting machine adopts a strip collector to integrate the seed melons scattered in the field into straight and narrow strips, and then collects the melons manually or mechanically. At present, the slitting machine popularized and applied in our country is mainly the 4ZT-2.0 seed melon slitting machine developed by the Agricultural Mechanization Research Institute of Xinjiang Academy of Agricultural Sciences, and the 4DT-2.0 melon slitting machine developed by the Agricultural Machinery Promotion Station of Tacheng District. The pick-up machine mainly uses the traditional roller pick-up method. This type of segmented melon harvesting machine is used in conjunction with a tractor to complete the separation and collection of seed melons and melon seedlings, as well as the subsequent picking and harvesting operations. The structure is simple and the production efficiency is low. In field tests, it was found that problems such as squeezing melons, hurting melons, unclear entanglement of melons and vines, and high loss occurred during machine operations. In particular, the harvesting period is long due to the low harvesting efficiency. If encountering a cold current, the melons will be frozen and broken and cannot be harvested, which directly results in a reduction in production and income.

The applicant searched and found that the Chinese invention patent with application number 201310440452.7 discloses a fully automatic melon harvesting machine, which mainly includes a melon picking and harvesting platform, a conveying device, and a seed removal machine. The melon picking and harvesting platform includes two groups of melon driving power rollers and melon picking buckets arranged obliquely. It has a good effect of removing vines and collecting vines, but the applicant found in practice that because the front and rear drive melon power rollers are all inclined, the front ends are very easy to insert into weeds or melon vines, so that entanglement, weeds, and vines occur. Blockage phenomenon will affect the use effect.

Contents of the invention

The technical problem to be solved by the present invention is: to overcome the above-mentioned shortcomings of the prior art, and to provide a picking platform of a melon harvester that can solve the problems of tangling grass, removing vines and leaking melons in the melon harvesting process.

In order to solve the above-mentioned technical problems, the technical solution proposed by the present invention is: a picking platform of a melon harvester, which is used to collect melons and transfer the melons to the seed picking device through a conveying device, including a frame, a front auger , rear auger, melon wheel and melon harvesting shovel; the front auger is arranged in the middle position directly in front of the frame, and the blades of the front auger are divided into left blades and right blades along the axial direction, so The helical directions of the left blade and the right blade are opposite and push the melon to both sides during use; the rear row auger includes a rear row left auger and a rear row right auger respectively located on both sides of the frame, the The blades of the rear left auger and the rear right auger have opposite helical directions and push the melon to the middle when in use; the melon wheel is arranged directly behind the front auger and is located in the Between the left auger and the right auger in the back row, the melon wheel includes a roller shaft hingedly installed on the frame and several melon boards arranged at intervals along the outer peripheral surface of the roller shaft, the melon board Extending along the axial direction of the roller, a disc-shaped baffle is fixed in the middle of the roller; behind the melon wheel, there is a melon harvester for transferring the melons pushed by the melon wheel to the conveying device. Shovel, the melon harvesting shovel is wedge-shaped and hinged on the frame, the bottom of the melon harvesting shovel is provided with rollers, the front end of the melon harvesting shovel is located below the melon puller, and the rear end of the melon harvesting shovel extends to the front end of the conveyor.

When the present invention is working, firstly, the auger in the front row pushes the melons in the width to both sides, and completes the separation of the melons and the vines (the connection between the mature melons and the vines is not firm, only a little force is needed) You can separate the melon from the vine); then the rear auger pushes the melon on both sides of the range to the middle, and also completes the separation of the melon from the vine. The front row of augers and the rear row of augers work together to integrate the separated melons into strips, and the melon puller and melon collecting shovel in the middle position quickly collect the pushed melons and send them to the rear conveying device in turn. , Seed taking device for follow-up processing.

The beneficial effects brought by the present invention are:

1) The picking table uses three sets of augers (one set of front augers and two sets of rear augers) to complete the separation and collection of melons and vines. Compared with the prior art that separates melon vines and melons through obliquely arranged power rollers, the present invention does not cause the melon vines to be entangled and blocked by weeds when the melons and vines are separated. In addition, the invention completes the work of strip gathering while the melon and vine are separated, which replaces the traditional disc-type strip gathering machine, has more reliable working efficiency, and reduces problems such as broken melons and leaked melons.

2) The invention can quickly collect melons and send them to the rear conveying device through the combined linkage of the melon picking wheel and the melon harvesting shovel, which replaces the traditional melon rolling harvesting method, further reduces the loss of leaking melons, and improves Transport efficiency, which in turn increases recovery efficiency.

3) The melon picker board is a plate structure, so that it is not easy to hook up the melon vines below during the rotation process, thereby preventing the melon vines from being entangled; in addition, the melon vines are pressed under the baffle, which further reduces the entanglement of the melon vines occur.

In order to further reduce the entanglement of melon vines and weeds, the present invention makes the following improvements to the above technical solution: 1) There is a rattan pressing roller between the melon wheel and the front auger, so that the melon can be pulled on the melon wheel Press down the melon vines and weeds before, avoiding the situation that the melon vines and weeds are entangled with the melon picker. 2) The melon harvesting shovel is provided with serrations, so as to cut off the melon vines and weeds brought up by the melon harvesting shovel during its travel. Combining the above two technical means, the problem of entanglement of melon vines and weeds is completely solved, thereby improving work efficiency.

A further improvement of the above technical solution is: the picking platform is provided with a depth-limiting wheel.

Preferably, the left and right ends of the front row of augers are respectively aligned with the right end of the rear row of left augers and the left end of the rear row of right augers.

Preferably, the length of the melon board is the same as that of the front row of augers.
