Description

Self-propelled Peanut Harvester

technical field

The utility model relates to a self-propelled peanut harvester, which belongs to a new type of agricultural peanut picking machine. the

Background technique

When harvesting peanuts, the traditional way is to pick the peanuts and store them in the farmer's own field, and then realize the shelling and screening of the peanuts, which takes up a lot of manpower and space, and is time-consuming and laborious. The existing peanut picking machines are roughly divided into two types, one It can only realize digging-type fruit picking in a single way. The picked fruit is wet fruit and still needs to be dried and peeled off manually; the other can realize the separation of fruit grains and peels, but it needs to be manually picked when picking the fruit, and then put into the fruit. Machine for fruit separation. With the development of agriculture, these picking methods that require manpower and time cannot meet the needs of higher production efficiency. It is necessary to provide a fully automatic fruit picking machine that can integrate fruit picking and fruit separation. the

The distance between the telescopic rollers and twisted cage rollers is 35 cm. On the fixed plate at the front end of the picker, the telescopic roller has a hole, and the telescopic guide sleeve is embedded in the hole. The telescopic guide sleeve and the telescopic roller are flat. The holes are divided into three groups. The telescopic teeth pass through the telescopic guide sleeve and extend out of the telescopic roller. ° Angle, there are four telescopic teeth on the twisting cage roller with telescopic guide sleeves, the telescopic teeth and the twisting cage roller are at 90°, the screw blades are fixedly connected to the twisting cage roller, the conveyor trough is behind the twisting cage roller, and the other end of the conveyor trough is connected to the threshing There is a fan hanging above the entrance of the threshing chamber and the exit of the threshing chamber, and the sieve is connected to the bottom. The end of the sieve is located above the conveyor belt, and one end of the conveyor belt is connected to the harvesting box. The driving wheel of the engine is connected to the driven wheel through the belt, and the driven wheel is connected to the winch roller gear through the chain. , the twisted cage roller gear is fixedly connected with the twisted cage roller, the twisted dragon roller gear drives the telescopic roller gear through a crossed chain, and the telescopic roller gear is fixedly connected with the telescopic roller. the

The telescopic roller has an eccentric shaft inside, the eccentric shaft is covered with a movable bushing, the telescopic teeth are fixedly connected to the movable bushing on the eccentric shaft, and the fixed plates are set on both sides of the eccentric shaft by contacting the inner wall of the telescopic roller to limit the eccentric shaft. bit. the

The positive effect of the utility model is that it can directly pick and pick peanuts in the field, and can separate peanuts from seedlings, reducing manpower input and saving labor. the

Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is further described: as shown in Figure 1, 2, 3, self-propelled peanut harvester is characterized in that: three pushing teeth 7 are fixedly connected on the base of pick-up device 1, The front of the push tooth 7 is a slightly downward-curved olecranon shape, and the upward slope of the tooth back of the push tooth 7 is 45°. Telescopic roller 2 and skein cage roller 3 have a distance of 35 cm and are movably connected to pick-up 1 through shafts. Telescopic roller 2 is lower than the front-end fixed plate of pick-up 1. There are holes on telescopic roller 2, and telescopic guide sleeves 6 telescopic guides are embedded in the holes. The sleeve and the telescopic roller are flat, and there are 5 openings in three groups. The telescopic teeth 4 pass through the telescopic guide sleeve 6 and extend to the outside of the telescopic roller 2 at an angle of 120°. There are four telescopic teeth 4 on the winding cage roller 3. Sleeve, telescopic tooth 4 is 90° with twisted cage roller 3, screw blade 8 is fixedly connected to twisted cage roller 3, behind twisted cage roller 3 is conveying trough 9, the other end of conveying trough 9 is connected to the entrance of threshing chamber 17, and the exit of threshing chamber 17 A fan 14 is suspended above, and a sieve 13 is connected to the bottom. The tail end of the sieve 13 is located above the conveyor belt 15, and one end of the conveyor belt 15 is connected to the harvest box 16. The driving wheel 5 of the engine is connected to the driven wheel 10 through the belt, and the driven wheel 10 is connected to the winch cage through a chain. The roller gear 11 is connected, and the cage roller gear 11 is fixedly connected with the cage roller 3, and the dragon roller gear 11 drives the telescopic roller gear 12 through a crossed chain, and the telescopic roller gear 12 is fixedly connected with the telescopic roller 2. the
