Description

A scissor type castor bean harvester

technical field

The invention provides a scissor type castor bean harvester, which belongs to the technical field of agricultural machinery.

Background technique

Castor bean is a tall annual herbaceous plant. It is planted from south to north in my country, and it is most planted in North China and Northeast China. It has strong adaptability, drought resistance, and salt-alkali tolerance.

Castor bean can be used as a fungicide in traditional Chinese medicine, and can be used as a disease caused by viruses and germs, with obvious effects and no side effects.

Castor beans are also made into anti-freckle and whitening cosmetics, which can improve skin metabolism, promote skin blood circulation, increase skin nutrition, remove skin spots and make skin delicate, smooth, tender and elastic, and have whitening, anti-aging and anti-freckle skin care.

Castor bean oil fatty acid is extracted and converted to produce mixed rare earths.

At present, domestic castor bean harvesting, threshing and cleaning still need to be carried out manually, and mechanical combined operations cannot be realized. Manual threshing and cleaning are labor-intensive and low in efficiency. the

Contents of the invention

The purpose of the present invention is to provide a self-propelled small castor bean harvester suitable for mountainous or hilly areas, which is a combined harvesting operation machine integrating harvesting, threshing and cleaning.

Its technical scheme is.

A scissor-type castor bean harvester, comprising a tractor, a reel, scissors, a screw propeller, a conveyor, a threshing drum, a draft remover, a vibrating screen, and a reel and a reel are fixedly installed on the upper end of the front frame of the tractor cab. Turn the wheel to move the castor bean plant to tilt towards the direction of the scissors. The scissors are composed of a moving knife and a fixed knife. The reciprocating motion of the moving knife cuts off the stem of the castor bean plant. The castor bean plants are sent to the conveyor and enter the threshing drum. After threshing, the plants are discharged from the miscellaneous discharge port. The castor beans and some fine impurities enter the drafter from the screen set on the threshing drum, and then enter the vibrating screen from the drafter. Two-channel fan winnowing, impurities are blown to the tail of the vibrating screen, castor beans fall from the screen holes of the vibrating screen into the screw auger, and enter the silo by the elevator.

Described a kind of scissor type castor bean harvester, in the air outlet of double-channel blower fan, add a clapboard, movable clapboard and fixed clapboard, one end of the movable clapboard is connected with fixed clapboard, and the other end of the movable clapboard is close to the two sides. The end of the inner wall of the side plate is movably installed in the arc-shaped guide groove, and the air outlet of the dual-channel fan is separated into two air channels, the upper air channel and the lower air channel. The upper air channel corresponds to the upper screen of the double-layer vibrating screen, and the lower air channel corresponds to the dual- For the lower screen of the vibrating screen, the angle between the double-channel fan and the horizontal plane of the ground is between 22 and 25 degrees.

In the scissors-type castor bean harvester, the threshing drum is composed of threaded rods installed on the toothed rods and a screen, and the threaded rods are fixedly installed on the toothed rods in the threshing drum in a spiral arrangement.

In the scissors-type castor bean harvester, the rotary connecting rod is installed at a position deviated from the center of the circle of the driving wheel, the rotary connecting rod is at the lowest point of the driving wheel, and the knife is opened to the maximum, and the rotary connecting rod is at the highest point of the driving wheel, and the knife is closed. .

Described a kind of scissors type castor bean harvester, reciprocating mechanism is fixed on the frame, and reciprocating mechanism is made up of drive wheel, rotary connecting rod, swing connecting rod and lifting connecting rod, and lifting connecting rod and a plurality of on the scissors The moving knife is connected, the connection between the lifting connecting rod and the moving knife is provided with a slotted hole, and the rotating connecting rod is provided with an adjusting handle.

Compared with the prior art, the present invention has the following advantages.

1. The scissor-type castor bean harvester integrates harvesting, threshing and cleaning in one machine, and is suitable for harvesting castor beans in mountains and hills.

2. The fan centrifugal or axial flow fan used in the existing harvester has flat and segmented blades, and the shape is a rectangular cut-angle blade. The air velocity on both sides of the air inlet is large, the air velocity in the middle is small, and the cleaning effect is poor; The invented fan adopts double suction paths to increase the air intake. The blades of the fan adopt straight and forward-curved arc-shaped blades to ensure the wind speed and the required flow. The seeds are large and the straw is thick. The floating coefficient of castor beans determines the wind speed and the cleaning flow of the fan. The wind speed is 15-16m/s, and the flow rate of the fan is 6000m3/hour. The parabolic principle is used to continuously throw the material twice. The wind speed and flow of each air duct can be adjusted through the fixed partition to achieve the best cleaning effect.

3. The grain bar is used for threshing. The grain bar has kneading performance. The thread bar is fixedly installed on the tooth bar in the threshing drum and arranged in a spiral shape, which has the function of threshing and advancing. The outer skin of the castor bean is fragile and does not damage the castor bean. Kernel, suitable for threshing of castor beans.

4. The stalks of castor beans are thick and the row spacing is large. Castor beans grow in the middle and upper part of the plant. When harvesting, the scissors cut off the stems away from the ground to reduce the feeding amount of the stalks and reduce the load on the fan and sieve. Use scissors to cut off the castor bean stems stalks, scissors work better than serrated knives.
