Abstract
The utility model discloses a rotary cultivator housing of a walking tractor. The rotary cultivator housing of the walking tractor comprises a left wing sub plate (2), an upper cover plate (3) and a right wing sub plate (5). The left wing sub plate (2) and the right wing sub plate (5) are symmetrically fixed on two sides of the upper cover plate (3), and the upper cover plate (3) correspondingly covers a rotary blade (1). The included angle beta formed between the front end of the upper cover plate (3) and the center of the rotary blade (1) and the included angle beta formed between the tail end of the upper cover plate (3) and the center of the rotary blade (1) are both controlled to be 125 to 145 degrees. Due to the structure, the rotary cultivator housing of the walking tractor has the advantages that the rotary cultivator housing is simple and reasonable in structure, good in soil crushing effect, small in size, light in weight and low in production cost, soil cannot stick to and accumulate on the rotary cultivator housing, and the like; and the whole walking tractor is enabled to be more flexible and convenient to operate and have better mobility.
Description
Technical field
The utility model relates to a kind of Walking Tractor-Rotary Tiller case, particularly a kind of 121 type Walking Tractor-Rotary Tiller cases.
Background technology
Rotovator is the agriculture cultivation machinery of finishing farming operation with walking tractor matching, because of characteristics such as it have that the hack ability is strong, the earth's surface is smooth after the rotary tillage, and is widely used.Be illustrated in figure 1 as known 121 type Walking Tractor-Rotary Tiller cases; it comprises left wing's daughter board 2; upper cover plate 3; rear plate washer 4 and right flank daughter board 5; upper cover plate 3 corresponding cover caps are on rotary blade 1; there is following defective in the housing for rotary cultivator of this structure in operation process: owing to form one between upper cover plate 3 and the backboard 4 less than the cone angle of 90 degree; the soil that splashes during operation is bonded on the cone angle of this case; greatly increased the weight of rotovator; the tractor driver extremely requires great effort when causing turning tune; the rotary tillage severity control is unstable; the soil of bonding can produce stronger frictional force with rotary blade; this not only increases the loss of power; and accelerating the wearing and tearing of rotary blade, the tractor driver has to usually to shut down cleaning and is bonded in clay on the case for this reason.For the ease of the clay on the cleaning case, when the design case, have to again increase the additional space between rotary blade and upper cover plate 3 and the backboard 4, the case volume is increased, increase production cost, but also can affect the hack effect.For this reason, many manufacturers and knowledgeable people have carried out R and D, but do not have so far desirable product to emerge.
Summary of the invention
The defects that exists for overcoming existing Walking Tractor-Rotary Tiller case, the purpose of this utility model provide a kind of simple and reasonable, hack is effective, volume is little, lightweight, production cost is low, the Walking Tractor-Rotary Tiller case of the long-pending soil that can not bond.
The utility model solves the problems of the technologies described above the technical scheme that adopts, it comprises left wing's daughter board, upper cover plate, right flank daughter board, it is characterized in that: described left wing daughter board and right flank daughter board symmetry are fixed on the both sides of cover plate, the upper cover plate cover cap is on rotary blade, and the angle β that is formed centrally in upper cover plate front end and terminal and the rotary blade is controlled at the 125-145 degree.
After adopting said structure, compared with prior art have the following advantages and effect, the one, remove the cone angle that forms between upper cover plate and the backboard, make the soil that splashes in the operation process be not easy to be bonded on the case, thereby solved the long-pending soil of case and needed the usually problem of cleaning, prolong the service life of rotary blade, improved the tractor-ploughing operating efficiency.The 2nd, the space between upper cover plate and the rotary blade is more reasonable, not only can reduce case volume, weight reduction, reduction cost, and can improve the hack effect.The 3rd, because the case volume reduces, reserved usage space, after suitably improving associated components, can make the radius of turn of 121 type hand tractors reduce 14 centimetres, it is more flexible that whole hand tractor handled, and mobility is better.

1 rotary blade wherein, 2 left wing's daughter boards, 3 upper cover plates, 4 backboards, 5 right flank daughter boards.
Embodiment
Shown in Figure 2, specific embodiments for the utility model Walking Tractor-Rotary Tiller case, comprise left wing's daughter board 2, upper cover plate 3, right flank daughter board 5, described left wing daughter board 2 and right flank daughter board 5 symmetries are fixed on the both sides of cover plate 3, upper cover plate 3 corresponding cover caps are on rotary blade 1, the angle β that is formed centrally in upper cover plate 3 front ends and terminal and the rotary blade 1 is controlled at the 125-145 degree, and best angle β is 136 degree.
