Description

Technical Field

[0001] The invention relates to an agricultural machine, in particular to a sugarcane harvester and a material collecting and unloading device thereof. Background Art

[0002] Sugarcane is one of the world's major sugar crops, with an average annual planting area of ​​about 22 million hectares. Among them, it is mainly distributed in Brazil, India, China, Cuba and Australia. my country's sugarcane planting area is about 1.7 million hectares, mainly distributed in Guangxi, Yunnan and Guangdong. There are three basic ways to harvest sugarcane: whole-stalk harvesting, segmented harvesting and segmented harvesting. In countries such as Australia and the United States that have achieved full mechanization, the mainstream model for sugarcane harvesting is large-scale segmented combine harvesters. At present, the sugarcane harvesters used in my country's main sugarcane producing areas mainly include large and medium-sized segmented combine harvesters, whole-stalk sugarcane combine harvesters and imported large segmented sugarcane combine harvesters.

[0003] Large-scale cut-type sugarcane combine harvesters use a conveying arm type lift. During operation, a sugarcane transfer vehicle accompanies the sugarcane harvester on one side. The cleaned cut sugarcane is transported to the transfer vehicle through the conveying arm type lift. It is suitable for mechanized harvesting of large-scale sugarcane planting. The disadvantage is that the transfer vehicle compacts the sugarcane field, and the driving skills of the transfer vehicle driver are relatively high. There are currently three types of conveying methods for medium-sized sugarcane combine harvesters: one is a conveying arm type lift. The disadvantage is that when operating in a small sugarcane field, it is difficult for the transfer vehicle to cooperate with the operation; the second is the net bag type sugarcane collection. After the net bag is full of sugarcane, it is directly pushed to the ground, and then a new empty net bag is reinstalled to collect sugarcane. The disadvantage is that a crane is required at the harvesting site to lift the net bag full of sugarcane onto the sugarcane transport vehicle, which requires a lot of auxiliary manpower; the third is the sugarcane collecting bucket. After the sugarcane collecting bucket is full of sugarcane, it is unloaded to the ground in a pile by a hydraulic device, and then a forklift is used to shovel the sugarcane segments onto the sugarcane transport vehicle, which requires a lot of auxiliary manpower.

[0077] See also Figure 6 and Figure 7 , Figure 6 This is a schematic diagram of the structure of a sugarcane collecting bucket according to an embodiment of the present invention. Figure 7 The figure is a schematic diagram of the structure of the rear unloading guide plate of an embodiment of the present invention. The sugarcane collecting bucket 4 is a frame with mesh holes, the rear part is higher than the front part, and is a containing frame formed by connecting and enclosing the sugarcane collecting cross beam 41, the sugarcane collecting vertical beam 42, the sugarcane collecting longitudinal beam 45 and the sugarcane collecting rear beam 49. The sugarcane collecting rear beam 49 is higher than the sugarcane collecting vertical beam 42. A front steel plate mesh 43, a side steel plate mesh 44 and a bottom steel plate mesh 46 are respectively installed between the sugarcane collecting cross beam 41, the sugarcane collecting vertical beam 42, the sugarcane collecting longitudinal beam 45 and the sugarcane collecting rear beam 49.

The other end of the lifting and unloading oil cylinder 5 is connected to the second lifting and unloading oil cylinder seat 47. The sugarcane collecting bucket 4 rises and falls on the lifting arm guide rail beam 36 through the extension and contraction of the lifting and unloading oil cylinder 5.

[0078] When the sugarcane harvester is in operation, the double-acting hydraulic cylinders in the translation cylinder 2 and the lifting and unloading cylinder 5 are in the shortest state, the sugarcane collecting bucket 4 is below the sugarcane discharging port at the rear of the sugarcane harvester and directly below the impurity removal fan 200, and the clean sugarcane segments enter the sugarcane collecting bucket 4. When the sugarcane collecting bucket 4 collects a certain amount of sugarcane, the sugarcane harvester stops working and drives to the side of the sugarcane transport vehicle, facing the transport vehicle compartment from behind, and the double-acting cylinders of the translation cylinder 2 are extended to the longest position. The sugarcane collecting bucket 4 moves backward and approaches the transport vehicle compartment under the action of the guide rail and the slide groove on the connecting base 1, and the lifting and unloading cylinder 5 is extended. The double-acting cylinder lifts the sugarcane collecting bucket 4 along the lifting arm guide beam 36 in the base frame 3 until the limit sleeve 7 fastened on the lifting arm 6 stops lifting at the upper end of the straight slot of the lifting arm guide beam 36, and the double-acting cylinder of the lifting and unloading cylinder 5 continues to extend. At this time, the sugarcane collecting bucket 4 rotates around the center of the connecting pin sleeve 63 on the lifting arm 6 to realize the unloading of sugarcane from the sugarcane collecting bucket 4 to the carriage of the transport vehicle. After unloading, the double-acting cylinder of the lifting and unloading cylinder 5 is shortened to the shortest, and then the double-acting cylinder of the translation cylinder 2 is shortened to the shortest, and the sugarcane harvester returns to the working state.

[0079] The present invention is used for collecting sugarcane in sugarcane harvesting operations, and unloading the sugarcane to a transport vehicle after collecting to a certain extent. During operation, the sugarcane collecting bucket is at the rear of the discharge port of the sugarcane harvester and directly below the impurity removal fan. When collecting to a certain extent, the sugarcane collecting bucket moves backwards through the translation cylinder, and then the lifting and unloading cylinder is started, so that the sugarcane collecting bucket rises and turns over to unload the sugarcane to the transport vehicle, so that the sugarcane harvester can operate smoothly in small plots and hilly and mountainous areas, solving the problems in the prior art that large and medium-sized sugarcane harvesters cannot be equipped with transfer vehicles to operate in small plots, and that medium-sized sugarcane harvesters need to be equipped with additional equipment and auxiliary personnel to operate.

[0080] Of course, the present invention may have many other embodiments.
