Abstract
The utility model discloses a miniature combine harvester which comprises a lifter assembly, a threshing assembly, a cleaning chamber and a power device. The miniature combine harvester is characterized in that the front end of the threshing assembly is conical, two rows of spiral blades are mounted at the conical front of the threshing assembly, an axial-flow threshing roller is arranged at the rear end of the threshing assembly, a plurality of rows of threshing teeth are evenly distributed on the surface of the threshing roller, and the threshing teeth are arranged in spiral form. The miniature combine harvester has the advantages that overall size is small, weight is light, the miniature harvester combine is convenient to transfer, blockage and jam are avoided, harvesting efficiency is high, and the miniature harvester combine is especially suitable for harvesting rice and wheat under different growth conditions in hilly areas and has broad market development prospect in countryside.
Description
Technical field
The utility model relates to a kind of crop cropper tool, specifically, is a kind of miniature combine harvester.
Background technology
Raising along with mechanization and automaticity; Grain header receives increasing peasant's hobby; And known miniature combine harvester adopts straw shift wheel mostly and holds up standing grain to refer at present, through grabbing rake the spike of rice or the wheat head is firmly grasped, and utilizes cutter to cut off then; Be transported to threshing bin through big screw feeder cylinder at last and carry out threshing, screening, separation, finally accomplish whole harvesting process.
The shortcoming of prior art is: in the harvesting process, usually occur that big screw feeder or threshing bin stop up, phenomenon such as stuck, cause mechanical failure easily, energy dissipation is big.And the complete machine quality is heavy, the paddy field with have the rice wheat of lodging not gather in, focus point is high, shifts inconvenience, causes that locomotive overturns easily etc.
The utility model content
The purpose of the utility model provides a kind of simple in structure, and lighter weight is not easy to be blocked the miniature combine harvester of machine.Its technical scheme is following:
A kind of miniature combine harvester; Comprise grain lifter assembly, threshing assembly, clean storehouse and power set; Its key is: the front end of said threshing assembly is tapered, and two row's helical blades are installed on cone, and the rear end of said threshing assembly is the axial-flow type threshing cylinder; Be evenly distributed with on the surface of threshing cylinder and get rid of a tooth more, a said tooth of getting rid of are and are arranged in parallel or helical arrangement more.
This programme integrates original big screw feeder and threshing portion, common thresher lateral arrangement is changed into axial arranged, thereby simplified structure is in light weight, does not stop up.
As further describing, said grain lifter assembly by about each nearside divider, a seeding supporting chain, hold up standing grain to dial to refer to and moving runner is formed, moving runner also is provided with cutter by its running of bearing drive between grain lifter assembly and threshing assembly.
Further describe, the said storehouse of cleaning is made up of metal shell, in cleaning the warehouse in storehouse, is provided with screen cloth again; The top of screen cloth is threshing bin; The bottom of screen cloth is a stir storehouse, and said threshing assembly is installed in said threshing bin, in said stir storehouse, is provided with little screw feeder.
Convenient for discharging, be provided with grass outlet in the upper end of said threshing bin, be provided with out the mouth of a valley in the lower end of said stir storehouse.
In order to implement convenience, said power set are electromotor or internal combustion engine, realize power transmission through belt pulley between the output shaft of these power set and the cylinder shaft and between the central shaft of cylinder shaft and little screw feeder.
The remarkable result of the utility model is: machine volume is little, and light weight is convenient to running, does not have and stops up and card machine phenomenon, and harvesting efficiency is high, is particularly suitable for knob different upgrowth situation rice wheat harvest and cuts, and has market development prospect widely in the rural area.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the partial schematic diagram of threshing cylinder 9 among Fig. 1.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further explain.
Like Fig. 1, shown in Figure 2, a kind of miniature combine harvester comprises grain lifter assembly, threshing assembly, cleans storehouse and power set, wherein:
The grain lifter assembly by about each nearside divider 1, a seeding supporting chain 2, hold up standing grain to dial to refer to 3 and moving runner 5 forms, moving runner 5 also is provided with cutter 4 by bearing 6 its runnings of drive between grain lifter assembly and threshing assembly.Realize from low to high the rice wheat being set upright through the grain lifter assembly, at last all spikes of rice or the wheat head are cut off through cutter 4, send at last and carry out threshing in the threshing assembly.
The front end of said threshing assembly is tapered; Two row's helical blades 7 are installed on cone; The rear end of said threshing assembly is an axial-flow type threshing cylinder 9, is evenly distributed with on the surface of threshing cylinder 9 and gets rid of a tooth 8 more, and the said tooth 8 of getting rid of are and are arranged in parallel or helical arrangement more.The threshing cylinder of original lateral arrangement is changed into axial arranged, simplify the structure, practiced thrift the space.
For the ease of the screening of cereal, the said storehouse of cleaning is made up of metal shell 11, in cleaning the warehouse in storehouse, is provided with screen cloth 14; The top of screen cloth 14 is threshing bin; The bottom of screen cloth 14 is a stir storehouse, and said threshing assembly is installed in said threshing bin, in said stir storehouse, is provided with little screw feeder 15.
Convenient for discharging, be provided with grass outlet 17 in the upper end of said threshing bin, be provided with out the mouth of a valley 16 in the lower end of said stir storehouse.
In the practical implementation process, said power set 13 are electromotor or internal combustion engine, realize power transmission through belt pulley 12 between the output shaft of these power set 13 and the cylinder shaft 10 and between the central shaft of cylinder shaft 10 and little screw feeder 15.
In the course of the work, the rice wheat is cut off the back by cutter 4 and directly sends into threshing cylinder 9 through two row's helical blades 7, carries out threshing through the threshing tooth on the threshing cylinder 98.The cylinder shaft 10 of threshing assembly realizes that by screen cloth 14 screening backs grass, paddy separate by power set 13 transmissions behind the rice-wheat threshing, and final straw or wheat straw are discharged body through grass outlet 17, and grain is seen off through going out the mouth of a valley 16, accomplishes the entire job process.
For the ease of equipment operation, in implementation process, this miniature combine harvester also is provided with walking assembly, as those skilled in the art habitual practice, adopt running on wheels or crawler travel usually, concrete technical scheme repeats no more.
