Spindle device for ensuring installing concentricity of cotton picker head

Abstract

The invention discloses a spindle device for ensuring installing concentricity of a cotton picker head and belongs to the technical field of manufacture of cotton harvesting machines. The spindle device for ensuring the installing concentricity of the cotton picker head is composed of a spindle and a spindle positioning mechanism, wherein a spindle bevel gear in the spindle device is meshed with a bevel gear in a spindle seat pipe. The spindle is mainly composed of a spindle rod, the spindle bevel gear arranged at the rear end of the spindle rod and a spindle head arranged at the front end of the spindle rod. The spindle positioning mechanism is mainly composed of a spindle sleeve, a first spindle bearing and a second spindle bearing, wherein the first spindle bearing and the second spindle bearing are fixedly arranged in the inner cavity of the spindle sleeve, the lower end face of the first spindle bearing is provided with a first oblique chamfer, and the upper end face of the second spindle bearing is provided with a second oblique chamfer. The spindle device can ensure the concentricity of a picking device in the assembling process and is simple and ingenious in structural design.

Description

technical field [0001] The invention relates to a spindle picking device, more specifically, to a spindle picking device for a cotton picker head which ensures installation concentricity. Background technique [0002] The range of cotton planting in my country is quite extensive. In the past, cotton picking mainly relied on human hands, which was labor-intensive and inefficient. With the continuous improvement of the level of agricultural mechanization in my country, the development of large-scale machine-picked cotton has become the general trend of my country's cotton industry, so cotton-pickers have appeared on the market. By using the cotton picker, the cotton picking speed can be effectively increased and higher income can be created for the cotton pickers. However, the picking effect, cleaning rate and cotton removal effect of the existing mechanized cotton picker heads in my country are not ideal. The core component of the picking effect, picking rate and doffing eff...

Problems solved by technology

However, the picking effect, cleaning rate and cotton removal effect of the existing mechanized cotton picker heads in my country are not ideal. The core component of picking effect, picking rate and doffing effect is the picking device, and the picking device is also the most vulnerable part in the head of a mechanical cotton picker, so the internal structure design of the picking device and the assembly between components are particularly important

[0003] After searching, there are existing technical disclosures for improving the existing picking device, such as Chinese patent application number 02290206.6, the date of authorization announcement is November 12, 2003, and the name of the invention is: mechanical cotton picking machine head with spindle picking device, The application relates to a spindle picking device for the head of a mechanical cotton picker, which is composed of a spindle picking mechanism, a spindle picking positioning mechanism, a spindle picking driving mechanism, a general positioning support mechanism, and a spindle picking guiding mechanism; The spindle picking rod, the spindle picking head and the spindle picking bevel gear are composed of a spindle picking tooth set composed of the spindle picking helical teeth evenly distributed on the outer surface of the spindle picking head; , consisting of the front sliding bearing and the rear sliding bearing which are fixedly arranged in the sleeve of the spindle; The mandrel bevel gear above, the mandrel power input gear arranged on the outer shaft end of the mandrel, the inner sleeve of the mandrel bearing arranged on the mandrel shaft body on the side of the mandrel near the mandrel power input gear and the setting It is composed of rolling bearings on the bevel gear of the mandrel and the inner sleeve of the mandrel bearing; this application has certain characteristics of good picking effect, high picking rate and good cotton removal effect, but this application ignores the concentricity in the assembly process. degree of question
