Description

A peanut picking machine

Technical field

The utility model relates to an agricultural machine capable of picking peanuts from peanut seedlings, in particular to a self-propelled peanut picking machine with an automatic picking function.

Background technique

At present, the structure of the known peanut picking machine is composed of a feed port, a fruit removing drum, a cleaning screen, a blower fan, a seedling stalk collecting box and a hoist. The peanut seedlings in the field are manually filled into the feeding port, and the peanuts are picked off by the fruit removal drum, and then cleaned and screened, and selected by a fan, and the cleaned peanuts are lifted by the elevator and then packed into bags; The seedling stalks are sucked into the seedling stalk collection box with the negative pressure of the blower fan. However, this general peanut picker has the following disadvantages: first, it needs to manually fill the peanut seedlings in the ground into the peanut picker, which is labor-intensive; second, it cannot move by itself. It is inconvenient to use on a tractor; third, the degree of automation is low, and many operators are required, generally 5 to 6 people, to complete the peanut picking operation.

Contents of the invention

In order to overcome the shortcomings of the existing peanut picking machine that requires manual filling, cannot move by itself, and has a low degree of automation, the utility model provides a peanut picking machine. The peanut picking machine can not only pick, screen, winnow and pack peanuts , and has automatic picking function and self-propelled function.

The technical solution adopted by the utility model to solve the technical problem is: the vertical pull rod at the front of the frame of the peanut picking machine is connected with the traction card of the tractor with a pin shaft, and the vertical pull rod is welded to the frame with two horizontal tie rods. A channel steel is welded on the left and right sides of the bottom, and the front end of the channel steel is fixed on the rear axle shaft of the tractor with a U-shaped clip and a nut. The front wheels of the tractor are removed and installed on the lower part of the frame, and the diesel engine of the tractor is also removed and fixed on the frame. The fruit removing drum is horizontally placed on the upper part of the frame, and the main shaft of the fruit removing drum is perpendicular to the forward direction of the tractor. A belt conveyor is arranged on the side of the tractor, and a scraper is fixed on the belt of the belt conveyor. The upper part of the belt conveyor is facing the feeding port of the peeling drum of the peanut picking machine, and the lifting of the belt conveyor is controlled by the oil cylinder fixed on the frame. A seedling-holding device is installed at the front of the belt conveyor, and the seedling-holding device is made up of sprocket wheels, chains and fixed upper teeth. During operation, the driver drives the tractor and aligns the front of the belt conveyor with the peanut seedlings, and the peanut seedlings are put into the belt conveyor under the joint action of the scraper on the belt conveyor and the teeth of the seedling lifter to realize automatic picking of peanut seedlings. pickup. The peanut seedlings are lifted by the belt conveyor, and the peanut seedlings are sent to the feeding port of the fruit-removing drum, and then the peanuts are picked off through the fruit-removing drum, and the cleaned peanuts are lifted by the elevator Finally, an operator picks up the bags; the crushed stalks are sucked into the stalk collection box by the negative pressure of the fan.

The beneficial effect of the utility model is that the peanut seedlings are automatically picked up, which saves manpower, and the operation is reduced to 2 people from the original 5-6 people. The peanut picking machine can be self-propelled, reducing physical labor and improving work efficiency.
