Description
Technical Field
The invention relates to a spindle for a cotton picker, in particular to a novel combined soft-tooth spindle, and belongs to the field of agricultural engineering.
Background
Cotton is the main economic crop in Xinjiang in China, and mechanized cotton picking is more and more popular with the continuous development of science and technology. As a key component of cotton picking, the problem of spindle failure has long been the primary factor limiting the development of cotton pickers. At present, the failure mode of the spindle is mainly the abrasion and the breakage of the hook tooth.
At present, spindles on the market are mostly integrated spindles, and spindles of the integrated type are troublesome and time-consuming when replaced. Generally, when the spindle head fails, the bevel gear and the spindle rod can be used continuously, and the cost of the cotton picker is increased while the integrated spindle is only discarded integrally to cause resource waste when the spindle head fails.
Disclosure of Invention
The invention aims to solve the problems of abrasion of the hook teeth and breakage of the hook teeth in the working process of the conventional spindle, and time, labor and resource waste when the spindle is replaced due to failure. The novel combined soft-tooth spindle can prolong the service life of the spindle, reduce the replacement cost of the spindle and save the replacement time of the spindle.
In order to achieve the purpose, the technical scheme of the invention is as follows: a novel combined soft-tooth spindle comprises a rubber soft-tooth sleeve (1), a connecting rod (2), a spindle rod (5) and a bevel gear (6).
A novel soft tooth spindle of combination formula, its characterized in that bevel gear (6) and spindle pole (5) as an organic whole, connecting rod (2) be threaded connection with being connected of spindle pole (5), external screw thread (7) have on spindle pole (5), internal thread (4) have on connecting rod (2), external screw thread (7) on spindle pole (5) can cooperate with internal thread (4) on connecting rod (2), its mode of screwing up is opposite with the rotatory direction of spindle during operation to guarantee the spindle at work, spindle pole (5) and connecting rod (2) can not take place the pine and take off.
A novel soft tooth spindle of combination formula, its characterized in that connecting rod (2) and the soft tooth of rubber cover (1) between the cooperation be interference fit, process out many barbs (3) simultaneously on connecting rod (2) to guarantee that relative slip can not take place between soft tooth of rubber cover (1) and connecting rod (2), and guarantee that soft tooth of rubber cover (1) can not break away from connecting rod (2) in work.
The novel combined soft-tooth spindle is characterized in that the rubber soft-tooth sleeve (1) has strong wear resistance and can ensure the service life of spindle teeth; meanwhile, the rubber soft gear sleeve (1) has certain elasticity and can deform when being subjected to a larger load in the working process; therefore, the hook teeth of the spindle are not easy to break, and the contact part (8) of the rubber soft tooth sleeve (1) and the spindle rod (5) has a certain distance with the spindle sleeve, so that the normal installation of the sleeve is not influenced.
The novel combined soft-tooth spindle is characterized in that the bevel gear (6) is obtained by corresponding deflection, and the tooth root of the bevel gear has strong bending strength; the tooth surface of the gear has strong fatigue resistance after being strengthened.
The invention has the beneficial effects that:
1. the combined spindle is formed, when the spindle fails, only the rubber soft gear sleeve (1) and the connecting rod (2) of the spindle are required to be replaced, the replacement is simple and convenient, the reserved spindle rod (5) and the bevel gear (6) can continue to work, resources are saved, and the use cost is reduced;
2. the rubber soft gear sleeve (1) has strong wear resistance and certain elasticity, and the hook gear is not easy to be worn and broken in the working process, so that the service life of the spindle can be greatly prolonged, and the economic benefit of the spindle is improved;
3. the bevel gear (6) after the modification and surface strengthening treatment has strong tooth root bending fatigue strength and tooth surface contact fatigue strength, and the service life of the bevel gear is greatly prolonged.
