Description

Horizontal header of a combine harvester

The utility model relates to a horizontal cutting platform, which is suitable for various full-feed combine harvesters to harvest vine crops, and belongs to agricultural machinery.

In recent years, with the adjustment of the planting structure in rural areas of our country, the planting area of economic crops mainly rapeseed has expanded rapidly. The harvesting of rapeseed has always been manual work, requiring more than two working days per mu, and the harvest is in the high temperature season, and the working conditions are very difficult. Farmers are eager to realize the mechanization of harvesting rapeseed and other crops, but the difficulty of mechanical harvesting of rapeseed is that : (1) Rapeseed seeds are small and spherical, with excellent fluidity and easy to cause leakage loss; (2) Rapeseed is an infinite inflorescence with long flowering time, inconsistent maturity, incomplete maturity may cause shriveled seeds, and full maturity is easy to fry pods; (3) Rapeseed plants are tall and entangled with each other. Forcibly pulling them apart will cause fried pods, which will bring many difficulties to mechanized harvesting. At present, there are few reports on rapeseed harvesting machinery abroad. Only the former East Germany has studied the entire technology and machinery. The techniques are mainly direct combined harvesting and segmented harvesting. The former is operated by an improved grain combine harvester, and the latter uses a special windrower to cut the rapeseed into strips, and then uses a picker with a picker to thresh off-line. Some large domestic farms use grain combine harvesters to harvest rapeseed. The requirement is to use new equipment to avoid leakage losses. Although this method improves efficiency and reduces costs, the loss rate of headers is still high.

The utility model aims to provide a special header that can effectively separate the winding and reduce fried pods, so that the header loss of the rapeseed combine harvester is greatly reduced.

The utility model is realized in the following way: a horizontal cutting platform of a combine harvester, which includes a cutting platform body, a row divider, a reel, a cutter, a conveyor and its transmission device and a lifting device. A power vertical cutter is installed on the top, the vertical cutter can be a reciprocating cutter or a disc cutter, the transmission part of the vertical cutter is connected with the header transmission device, and directly uses the power to drive the header to work; The finger of the reel is a flexible finger with a diameter of 2 to 5 mm, and the installation end of the flexible finger is threadedly connected with the grain rod, and is fastened with an adjusting nut, or multiple groups are arranged at the installation end of the flexible finger. Circlip slot, the finger is fixed in the hole of the bat with a circlip so that the length of the finger can be adjusted.

The advantages of the utility model are: (1) the vertical cutter is adopted, which can effectively cut and separate the rape in the area to be cut and the rape in the non-cut area when they are intertwined with each other, so as to avoid violent shaking of the crops caused by pulling and frying; (2) The flexible and adjustable finger is used to make the finger gently and evenly pull the crops to reduce the loss of fried pods; (3) The power of the header is directly used, the transmission line is short, and the structure is simple.

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

Fig. 1 is a side view of a horizontal header with a reciprocating cutter type vertical cutter installed in the utility model.

Fig. 2 is a side view of the utility model installed with the horizontal header of the disc cutter type vertical cutter.

Fig. 3 Fig. 4 is the structural diagram of the finger of the utility model horizontal cutting platform reeling crops.

The horizontal cutting platform of the utility model is composed of a cutting platform body 1, a row divider 4, vertical cutters 6 and 7, a reel 5, a cutter 3, a conveyor 2 and its transmission device and a lifting device. The upper front of the device, shown in Figure 1 is a reciprocating vertical cutter 6. What shown in Fig. 2 is disc type vertical cutter 7. The power to drive the cutting table is transmitted to the crank slider wheel of the reciprocating knife type vertical cutter or the pulley of the disc cutter type vertical cutter respectively by the transmission device through the chain or V-shaped belt, so as to drive the vertical cutter to work. This implementation The finger diameter on the straw of the grain reel is thinner and more flexible than in the example. The length of the dial finger is adjustable, and Fig. 3 is a threaded adjustable dial finger, the installation end of the dial finger is connected with the screw thread of the bat, and after being adjusted to an appropriate length, it is tightened with an adjustment nut. Fig. 4 is a circlip adjustable dial finger, the mounting end of the dial finger has multiple groups of snap ring grooves, and the dial finger is fixed on the bat with two ring rings. The horizontal cutting platform of the utility model is suitable for various full-feed combine harvesters.

When the machine is working, the splitter first separates the area to be cut from the non-divided area at the root of the rapeseed. The intertwined pods on the upper part of the rapeseed are cut and separated by the vertical cutter to avoid pulling the pods. The rape stalks that have been separated in the area to be cut are gently pushed into the header, and the cutter cuts the rape stalks from the root, and is sent to the feeding port by the screw finger conveyor, and then transported to the thresher through the intermediate conveying device The threshing is separated, and they are discharged out of the machine through the grain receiving port and the grass discharge port respectively.
