Description

TECHNICAL FIELD

[0001] The utility model relates to a raking machine field, especially a lateral raking machine. BACKGROUND

[0002] The existing raking machine has the types such as traction type, suspension type, and its working component is a row of transverse parallel round or spiral spring teeth. When working, the raking machine spring tooth tip touches the ground, and the grass cut by the mower is raked into horizontal grass strips (that is, the grass strip is perpendicular to the advancing direction of the machine). Because the grass strip is relatively close, it is not conducive to drying, and is mixed with many things, is not neat, and is not conducive to subsequent operation. The operation speed is also relatively low, generally 4-5 kilometers / hour. The size of the raking collected grass strip of this type of machine can be manually controlled, and it is usually used in natural grassland with low yield.

[0003] The main working component of the drum type raking machine is a raking drum rotating around the horizontal shaft. The end face of the drum forms an angle with the advancing direction of the machine, that is, the advancing angle; the angle between the rotating end face of the drum and the tooth bar is the drum angle. It can be divided into two types of right angle drum type and inclined angle drum type, the drum angle of the former is 90°, and the advancing angle is 45°; the drum angle of the latter is less than 90°, and the advancing angle is greater than 90°; the quality of the raked grass strip is relatively high, and the raking loss is relatively small. The drum is composed of 3-6 parallel tooth bars provided with rows of raking spring teeth, the two ends of the tooth bar are hinged to the two mutually parallel rotating end faces of the drum, forming a parallel four-bar mechanism, so that the direction of the spring teeth always remains parallel during the rotation of the drum. When working, the spring teeth advance with the machine while rotating around the horizontal shaft, and the pasture on the ground is formed into continuous grass strips consistent with the advancing direction on one side of the drum through the action of the spring teeth, which is loose and neat, conducive to the drying of the pasture and subsequent operation. The size of the raked grass strip is directly related to the grass yield per unit area of the grassland, and is suitable for grasslands with high yield. In low-yield grasslands, double-row drum type raking machines can be used to rake larger grass strips. Some drum type raking machines can also change the rotation direction of the drum for turning grass operation. According to the hanging connection mode, it can be divided into traction type and suspension type, the latter is driven by the power output shaft of the tractor to rotate the drum, the former is driven by the walking wheel, the ratio of the rotation speed of the drum to the advancing speed of the machine is kept constant, and there is a large gap in front of the drum, which is conducive to raking. It is only suitable for large-scale grassland operation.

[0004] The finger wheel type raking machine is composed of a plurality of finger wheels sleeved on the frame shaft, which is simple in structure and has no transmission device. When working, the finger wheels contact the ground and rotate by the friction of the ground, raking the pasture to one side to form continuous and neat grass strips. The angle between the plane of the finger wheel and the advancing direction of the machine is generally 135°, and the operation speed can reach more than 15 kilometers / hour, which is suitable for raking pasture with high yield, residual crop straw, and residual film in the soil. However, the contact of the finger wheel with the ground causes a large amount of dust during the raking process.

[0005] The folding rotary rake has two types of rotary parts, i.e., a rotary rake type and a spring tooth type. The rotary rake type rake has 6-8 rakes on each rotary part. During operation, the rake is driven by a power output shaft, controlled by a fixed cam installed in the middle, and rotates around the central shaft while rotating itself, thereby completing the actions of raking and spreading grass. The rotary spring tooth type rake has a plurality of spring teeth installed around a rotary part, and the spring teeth are opened by the centrifugal force of rotation to perform the action of raking. If the installation angle of the spring teeth is changed, the action of spreading grass can be performed. The rotary rake has loose and well-ventilated raked grass strips, small loss of pasture, light pollution, and an operation speed of 12-18 km / h, and is convenient for matching with a pickup device. However, the rotary rake has high requirements for the power of a tractor, a complex structure, and high production cost. Content of the utility model
