CN2455053Y - Combine harvester - Google Patents

Abstract

The utility model discloses an improved combine harvester which comprises a motor vehicle and a power transmitting device. The utility model is composed of a header [1], a gap bridge [2], a threshing barn [3], a seed hull removing mechanism, an elevating mechanism, etc. The utility model is characterized in that an upper elastic tooth 8 of a propeller 7 is fixed and is arranged in the spiral way, and shaft flow threshing technique is used in a threshing part. Namely, a threshing rotary roller 4 is arranged in the threshing barn 3 along the running direction of a vehicle body, and the bottom of the threshing barn 3 is provided with a sieve-shaped tile plate 6 which is matched with the threshing barn 3. The utility model solves the problems that at the time of feeding, a traditional harvester is easy to stacked, blocked and clamped in the propeller, and in the process of threshing, the breakage rate of cereal seed is overhigh, and has the advantages of simple structure, low cost, good threshing effect, etc.

Description

A kind of combine

The utility model relates to a kind of improved combine.

Elastic claw on the existing combine harvester cutting table place propeller is that whole row stretches simultaneously, and the shortcoming of this structure is: when charging, the cereal heap takes place easily block up and block angle of rake phenomenon; In addition, the general rolling flow type threshing technology that adopts of combine threshing part also claims " threshing of roll formula ", and it is to realize threshing according to the artificial two roll screw die spacings of adjusting of receipts cereal situation, and its shortcoming is: cereal kernel is easily broken, and breakage rate is too high.

The purpose of this utility model is to provide a combine: one, and can avoid the stifled cereal of ceding of Taiwan place heap to block the generation of propeller phenomenon; Its two, it need not adjust the screw die spacing, just be suitable for various grain threshings and handle, and threshing performance height, seed breakage rate is low.

For achieving the above object, a kind of combine of the utility model comprises motor vehicle and power transmission, allowanced for bark with mechanism such as elevator by the ceding of Taiwan, gap bridge, threshing bin and seed and to constitute, it is characterized in that: angle of rake elastic claw is for fixing and helical arrangement in the ceding of Taiwan; The axial threshing technology is partly adopted in threshing, that is: move towards along vehicle body in threshing bin, and a toothed threshing tumbler is arranged, and sieve shape watt plate with matching is arranged at the threshing bin bottom.

The utility model has following advantage:

1, simple in structure, cost is low;

2, cereal kernel threshing performance height, breakage rate is extremely low;

3, can avoid the stifled propeller that blocks of cereal heap.

The utility model has following embodiment:

Fig. 1 is a principle schematic of the present utility model;

Fig. 2 is the utility model threshing bin structural representation;

Fig. 3 is the utility model propeller structure schematic diagram;

Walking of the present utility model and power section can be adopted small tractor and do suitable adjustment repacking.As shown in figures 1 and 3, when cereal was sent to propeller [7] in the ceding of Taiwan [1], the elastic claw of helical arrangement [8] was evenly eaten cereal into gradually, thereby prevented effectively that the cereal heap is stifled and block propeller [7]; Subsequently, cereal is being sent in the threshing bin [3] through pass a bridge [2] under the connecting gear effect, as shown in Figure 2 under the effect of axial threshing tumbler [4], cereal axially moves backward and rotates strike, rubbing on the tooth [5] of the sieve shape watt plate [6] of threshing bin [3] bottom and threshing tumbler [4] along threshing tumbler [4], realizes threshing; At last, through separation allowance for bark, operation such as seed elevator finishes the harvesting task.

Claims (1)

1, a kind of combine comprises motor vehicle and power transmission, allowance for bark with mechanism such as elevator by the ceding of Taiwan [1], pass a bridge [2], threshing bin [3] and seed and to constitute, it is characterized in that: in threshing bin [3], move towards along vehicle body, the threshing tumbler [4] that a band tooth [5] is arranged, sieve shape watt plate with matching [6] is arranged at threshing bin [3] bottom; The elastic claw [8] of the last propeller [7] of the ceding of Taiwan [1] is fixing and helical arrangement.
