Description

Cane collecting and unloading device

technical field

The invention relates to the field of agricultural machinery, in particular to a sugarcane collecting and unloading device of a segmented sugarcane harvester.

Background technique

my country is the world's largest producer of sugarcane, and sugarcane is an important economic crop in southern my country and the main raw material for my country's sugar industry. Its planting areas are mainly distributed in Guangxi, Yunnan, Guangdong, Hainan and other provinces. Guangxi, especially the region with the most advantageous development of the sugar industry, has formed one of the pillar industries of Guangxi's economy.

At present, most of the sugarcane harvesting in my country is still in the relatively primitive harvesting method of manual felling, which requires large labor force, high operating intensity and low harvesting efficiency. With the increase of sugar demand and the transfer of rural labor, the cost of sugarcane production has also increased rapidly. Therefore, it is an inevitable trend to use mechanized harvesting instead of manual harvesting in sugarcane harvesting. However, most of the sugarcane harvesting machines currently used in the field of sugarcane harvesting are medium and large-scale combine harvesters. When harvesting sugarcane, the segmented sugarcane is transported to a transshipment truck through an elevator, and a transshipment truck is required to accompany the harvesting. It is only suitable for use in a small number of relatively flat and large sugarcane fields, while the natural environment conditions for sugarcane production in my country are relatively harsh, most of the sugarcane fields are on hilly slopes, and small sugarcane fields are planted. There are many small-scale sloping fields and large slopes, and the sugarcane collection method using "elevator + transfer truck" is difficult to implement on such small-sized sugarcane fields.

Therefore, it is very necessary to develop a sugarcane collecting and unloading device that enables the sugarcane harvester itself to have the functions of collecting and unloading sugarcane, which has an important role in promoting the popularization of sugarcane harvesting mechanization.

SUMMARY OF THE INVENTION

The purpose of the present invention is to provide a sugarcane collecting and unloading device for a segmented sugarcane harvester, so as to solve the problem that the sugarcane collecting method of the "elevator + transfer vehicle" used by the sugarcane combine harvester under the prior art is difficult to use in small Technical issues in the implementation of the plot.

The bracket is hinged through the pin shaft, the swing bracket and the sugarcane harvester are hinged through the pin shaft, one end of the downward tilting cylinder is hinged with the swing bracket through the pin shaft, and the other end is hinged with the sugarcane harvester through the pin shaft, and one end of the lifting cylinder is connected with the sugarcane harvester. The box is hinged through a pin shaft, and the other end is hinged with the swivel bracket through a pin shaft, and the cane collecting box is a bucket-type structure that is only open at the upper part, and the other sides and bottom surfaces are enclosed.

When the sugarcane collecting and unloading device of the present invention is used for the harvesting operation of the segmented sugarcane harvester, the sugarcane collecting box is basically in a horizontal position, the open cane collecting port on the upper part faces upwards, and the sugarcane harvester is thrown from the bottom of the impurity removing fan. The harvested and cut sugarcane sections are stored in the sugarcane collection box. When the sugarcane collection box is full, the sugarcane harvester is moved to a suitable sugarcane unloading position. The hydraulic control system is used to control the extension of the downward tilting oil cylinder to make the swing bracket tilt downwards. Then control the elongation of the lifting cylinder to raise the cane collecting box and turn it backwards, and finally dump the sugarcane section in the cane collecting box and load it on other transport vehicles to achieve the purpose of collecting and unloading the sugarcane.

Preferably, the downward tilting oil cylinder and the lifting oil cylinder of the cane collecting and unloading device are symmetrically installed on both sides of the cane collecting box. In order to ensure better stability in the process of gathering and unloading cane.

Preferably, the cane collecting and unloading device further includes a cane unloading control system, and the cane unloading control system includes a downward tilting oil cylinder control device, a downward tilting oil cylinder extension position sensor, a lifting oil cylinder control device, and a lifting oil cylinder extension position sensor. In the process of unloading the sugarcane, after the downward tilting oil cylinder control device controls the downward tilting oil cylinder to extend to the designated position, the lifting oil cylinder control device can control the lifting oil cylinder to extend, so as to lift and turn the cane collecting box backwards, so as to ensure the cane collecting box and harvesting. The lower part of the impurity removal fan does not collide. After the unloading of the sugarcane is completed, firstly start the retraction stroke of the lifting cylinder to lower the sugarcane collection box and turn it over in the swing bracket, and then start the retraction stroke of the downward tilting cylinder to raise the swing bracket to the normal working position.

Preferably, the cane unloading control system is an automatic program control system, and the automatic program control system includes a program control module, a cane unloading switch, and a return switch. Press the cane unloading switch, the cane collecting and unloading device can automatically complete the unloading procedure, and when the return switch is pressed, the cane collecting and unloading device can automatically complete the returning procedure, with a high degree of automation.

Preferably, the bottom plate and the rear side plate of the cane collecting box are light panels, and the other side panels are mesh perforated plates. The bottom plate and rear side panels of the cane collecting box are light panels, which are conducive to the flow of cane segments during the unloading process, and the other side plates are mesh perforated plates, which are conducive to observing the collection of cane segments in the cane collecting box.

The sugarcane unloading method using the sugarcane collecting and unloading device of the present invention is as follows:

(1) Manipulating the downward tilting oil cylinder to extend and drive the swing bracket and the cane collecting box to swing and tilt downward;

(2) Control the extension of the unloading oil cylinder to drive the cane collecting box to lift and turn backwards to dump the sugarcane segments in the sugarcane collecting box and load them on other transport vehicles;

(3) After the unloading of the sugarcane segment is completed, control the unloading oil cylinder to shorten and drive the sugarcane collecting box to descend and turn over to the original position in the swing bracket;

(4) Control the downward tilting oil cylinder to shorten and drive the swing bracket and the cane collecting box to lift up and reset to the original state.

The sugarcane collecting and unloading device provided by the invention can play the role of storing and unloading the sugarcane segments. After the sugarcane collecting box is full of the sugarcane segments, the sugarcane in the sugarcane collecting box can be unloaded and loaded onto other transport vehicles. The sugarcane harvesting operation is carried out again. The sugarcane collecting device is installed on the sugarcane harvester, so that the sugarcane harvester itself has the function of collecting sugarcane, which overcomes the shortcomings of the "elevator + transfer vehicle" method of collecting sugarcane used in the original sugarcane combine harvester, and enables mechanized sugarcane harvesting. Implementation on smaller plots is of great significance to promoting the mechanization of sugarcane harvesting.
