Description
Technical field
The utility model relates to the chain delivery machanism being convenient to spoil disposal.
Background technology
Chain delivery machanism is usually used in the occasion that transmitting ratio is constant, transmission power demand is larger, is common in field machine.But, due in the more occasion of the dusts such as agricultural, earth, sprocket wheel after long-time running for piling up earth, cause conveyer chain and sprocket engagement difficulty, make conveyer chain shake and be unfavorable for stable drive, the situation that conveyer chain takes off chain even occurs, greatly reduces the reliability and stability of transmission.
Utility model content
In order to overcome the deficiencies in the prior art, the purpose of this utility model is to provide the chain delivery machanism being convenient to spoil disposal, effectively, stably can discharge earth, prevents earth from gathering.
The purpose of this utility model realizes by the following technical solutions:
Be convenient to the chain delivery machanism of spoil disposal, comprise two sprocket wheels and be set around the conveyer chain of two sprocket wheels, sprocket wheel comprises wheel body and is divided into the gear teeth of wheel body outer peripheral edges, wheel body central authorities are provided with axis hole, the outer peripheral edges of wheel body have the multiple mud drainage slots radially extended, each mud drainage slot is between the adjacent teeth root of adjacent teeth, and the end face of wheel body is provided with cavity, and mud drainage slot is communicated with cavity respectively.
Preferably, mud drainage slot is straight trough, and the bottom land place circle diameter of each mud drainage slot is less than each gear teeth tooth root portion place circle diameter.
Preferably, cavity is circular, and this cavity is coaxial with wheel body.
Preferably, the chamber wall diameter of cavity increases from the inside to the outside gradually.
Preferably, the hole wall of axis hole has keyway.
Compared to existing technology, the beneficial effects of the utility model are:
The utility model is by the setting of mud drainage slot and cavity, earth between adjacent teeth can be bled cavity rapidly, effectively from mud drainage slot, again under the rotary action of wheel body, it is external that earth in cavity is taken out of wheel, thus stablize spoil disposal, prevent earth from accumulating between adjacent teeth, greatly improve the reliability and stability of transmission, and the more occasion of other dust, earth can be widely used in, strong adaptability.
Accompanying drawing explanation
Fig. 1 is the structural representation that the utility model is convenient to the chain delivery machanism of spoil disposal;
Fig. 2 is the cutaway view of the utility model sprocket wheel.
In figure: 1, sprocket wheel; 11, wheel body; 111, axis hole; 112, mud drainage slot; 113, cavity; 114, keyway; 12, the gear teeth; 2, conveyer chain.
Detailed description of the invention
Below, by reference to the accompanying drawings and detailed description of the invention, the utility model is described further:
The chain delivery machanism being convenient to spoil disposal as shown in Fig. 1 ~ 2, comprise two sprocket wheels 1 and be set around the conveyer chain 2 of two sprocket wheels 1, sprocket wheel 1 comprises wheel body 11 and is divided into the gear teeth 12 of wheel body 11 outer peripheral edges, wheel body 11 central authorities are provided with axis hole 111, the outer peripheral edges of wheel body 11 have the multiple mud drainage slots 112 radially extended, each mud drainage slot 112 is between the adjacent teeth root of adjacent teeth 12, and the end face of wheel body 11 is provided with cavity 113, and mud drainage slot 112 is communicated with cavity 113 respectively.
By the setting of mud drainage slot 112 and cavity 113, earth between adjacent teeth 12 can be bled cavity 113 rapidly, effectively from mud drainage slot 112, again under the rotary action of wheel body 11, earth in cavity 113 is taken out of outside wheel body 11, thus stablize spoil disposal, prevent earth from accumulating between adjacent teeth 12, greatly improve the reliability and stability of transmission, and the more occasion of other dust, earth can be widely used in, strong adaptability.
Wherein, for the sprocket wheel 1 as propulsive effort, generally have keyway 114 at the hole wall of axis hole 111, rotate to make the stable drive sprocket 1 that drives of the output shaft of peripheral driver.Mud drainage slot 112 is between the tooth root portion of adjacent teeth 12, then the earth on conveyer chain 2 and on wheel body 11 all will to bleed cavity 113 through this mud drainage slot 112, to make conveyer chain 2 effectively closely engage with the gear teeth 12, avoid conveyer chain 2 to shake.
For realizing even spoil disposal, mud drainage slot 112 is straight trough, and the bottom land place circle diameter of each mud drainage slot 112 is less than each gear teeth 12 tooth root portion place circle diameter.Then arranging of mud drainage slot 112 will not affect the intrinsic effect of the gear teeth 12, and also do not affect engaging of conveyer chain 2 and the gear teeth 12, this mud drainage slot 112 may extend to the two ends end face of wheel body 11 simultaneously, with farthest spoil disposal.
For promoting reliability and the homogeneity of spoil disposal further, cavity 113 is in circular, and this cavity 113 is coaxial with wheel body 11.Wherein, cavity 113 is preferably arranged on the two ends end face of wheel body 11, also only can be arranged on one end end face of wheel body 11.
For the chamber wall avoiding earth to accumulate in cavity 113, the chamber wall diameter of the cavity 113 of this example increases from the inside to the outside gradually, then will form obtuse angle at the bottom of the chamber wall of cavity 113 and the chamber of cavity 113, and discharge fast to make earth.
To one skilled in the art, according to technical scheme described above and design, other various corresponding change and deformation can be made, and all these change and deformation all should belong within the protection domain of the utility model claim.
