Description

Blade type anti-winding fruit picking roller

technical field

The invention belongs to the field of agricultural machinery and equipment, and relates to a fruit-picking roller of a peanut harvester, in particular to a blade-type anti-winding fruit-picking roller.

Background technique

China is the world's largest producer and consumer of peanuts, as well as the largest exporter. Its planting area accounts for about 20% of the world's total area, ranking second in the world, and its total output ranks first in the world. For a long time, due to peanut Planting, harvesting and processing are mostly done manually, which is labor-intensive and inefficient. In the whole process of peanut production, labor in the harvesting link accounts for more than 1/3 of the whole process, and operating costs account for more than 50% of the whole peanut production cost. The development of peanut harvesting mechanization has practical significance for reducing operating costs, improving operating efficiency, and increasing farmers' income.

At present, the fruit-picking rollers of the existing semi-feeding peanut combine harvesters are composed of a pair of relatively rotatable rollers assembled in different phases. When working, the two rollers rotate relatively under the drive of the transmission mechanism, thereby With the help of the beating action of the radial fruit-picking blades on the rollers, the peanuts on the peanut seedlings fed between the two rollers are slapped and picked off. However, due to the large-scale application of peanut coating technology in recent years, when harvesting coated peanuts, it is inevitable that there will be residues of plastic coating on the machine shaft, and the plastic coating is easy to wrap around the two ends of the fruit picking roller, especially It is very easy to be entangled in the gap between the shield and the end plate of the roller body, resulting in frequent shutdowns for cleaning, which seriously affects the production efficiency of peanut combined harvesting, and is often difficult to clean and takes a lot of time. Therefore, the structure of the fruit picking roller needs to be developed. advanced optimization.

Contents of the invention

The purpose of the present invention is to address the shortcomings of the existing fruit picking rollers of peanut combine harvesters, and provide a blade-type anti-winding fruit picking roller that can effectively solve the problem of plastic film winding peanut picking rollers, with high fruit picking efficiency and good anti-winding effect .

The technical solution of the present invention is: a blade-type anti-winding fruit picking roller, including a fruit picking roller seat, the fruit picking roller seat is divided into an upper fruit picking roller seat and a lower fruit picking roller seat, an upper fruit picking roller seat and a lower fruit picking roller A pair of fruit-picking roller bodies are symmetrically arranged between the cylinder seats, and the upper fruit-picking roller seat is connected with a transmission mechanism. The fruit-picking roller body is a cylinder, and the fruit-picking roller body includes a fruit-picking roller and a fruit-picking blade. On the fruit picking roller, connecting shafts are arranged at both ends of the fruit picking roller body, and bearing end plates are arranged outside the connecting shaft. There is a gap between the connecting shaft and the bearing end plates. The fruit picking roller includes an upper end, a middle part and a lower end, The upper end, the middle part and the lower end are all cylindrical, and the diameters of the upper end and the lower end are smaller than the diameter of the middle part. The fruit picking roller body also includes a helical blade, and the helical blade is fixed on the upper end and the lower end of the fruit picking roller The periphery of the circumference; the end face of the upper end of the fruit picking roller is the upper end face, the end face of the lower end is the lower end face, the connecting shaft is arranged on the upper end face and the lower end face, and a round pipe section protective sleeve is installed on the connecting shaft, and the bottom surface of the round pipe section protective sleeve It is circular, the side wall is semi-circular tubular, and the protective sleeve of the circular tube section is located on the periphery of the bearing end plate.

Preferably: there are multiple helical blades, and the multiple helical blades are evenly distributed on the periphery of the upper end and the lower end of the fruit picking roller.

Preferably: the side of the helical blade installed at the upper end is at an angle of 40° to 50° with the plane where the upper end surface of the upper end is located, and the side surface of the helical blade installed at the lower end is also at an angle with the plane at which the lower end surface of the lower end is located. 40°～50° angle.

Preferably: in a pair of fruit-picking roller bodies, four fruit-picking blades are arranged on each fruit-picking roller body, and the four fruit-picking blades are evenly distributed on the periphery of the fruit-picking roller body, and the The four fruit-picking blades are in one-to-one correspondence respectively, and the corresponding fruit-picking blades on the two fruit-picking roller bodies form an angle of 45°.

Preferably: the fruit-picking roller body is obliquely arranged on the fruit-picking roller seat, and the upper end surface of the fruit-picking roller forms an angle of 20° to 30° with the upper end surface of the upper fruit-picking roller seat.

Preferably: the fruit-picking blade is fixedly installed on the blade seat by a round head bolt.

Preferably, a protective cover is also arranged on the connecting shaft, and the protective cover covers the outside of the protective sleeve of the round pipe section.

The beneficial effects of the present invention are:

The structure of the traditional fruit-picking roller is as follows: a pair of corresponding fruit-picking roller bodies are set on the fruit-picking roller seat, and fruit-picking blades are installed on the fruit-picking roller body. The structure is easy to cause sundries to wind up on the bolts, and the upper end and the lower end of the fruit picking roller body are all provided with installation shafts, and sundries such as films mixed in harvested fruits are easy to wind up on the installation shafts.

The present invention improves on the above problems, and the beneficial effects realized include the following aspects:

(1) A new type of anti-winding fruit picking roller mechanism. Spiral blades are installed on the upper and lower ends of the fruit picking roller. The spiral blades can grind the film and other sundries mixed in the harvested fruit to prevent the film from being entangled in the fruit picking. On the shaft of the roller, the winding rate of the plastic film is effectively reduced, the resistance loss caused by the mechanical transmission project is reduced, and the efficiency of mechanical transmission and fruit picking is improved.

(2) The spiral blades are arranged obliquely at a 45° angle, and are evenly distributed on the upper and lower ends of the fruit picking roller, which can achieve better mincing effect.

(3) The fruit picking rollers are installed obliquely on the fruit picking roller seats, and the corresponding blades on the two fruit picking roller seats are at an angle of 45° to each other. When a pair of fruit picking rollers move relative to each other, the fruit picking leaves can be guaranteed It achieves better beating effect on the fruit, high fruit picking efficiency and good effect.

(4) The fruit-picking blade is fixed on the blade seat by round-head bolts, and the round-head bolts are not easy to cause debris to be entangled.

(5) The bottom surface of the protective sleeve in the round pipe section is circular, and the side wall is semicircular tubular. On the one hand, it prevents the peripheral sundries from entering the connecting shaft, and on the other hand, the crushed film and other sundries can pass through the semicircular hollow building at the bottom. Next, avoid excessive accumulation of crushed objects.

(6) Protective cover is set on the outside of circular pipe section protective cover, protective cover can prevent extraneous debris from entering on the connecting shaft of the upper end and the lower end of the fruit-picking roller, avoiding excessive debris, resulting in debris entanglement.
