Description

Technical Field

[0001] This utility model relates to the field of insulator technology, specifically a traction cotton harvester. Background Technology

[0002] A cotton harvester is a highly efficient and automated cotton harvesting device that can complete a large amount of cotton harvesting in a short time. With the continuous development of agricultural technology, cotton harvesters have been widely used in cotton production, greatly improving the efficiency and benefits of cotton production.

[0003] Existing patent CN208029492U discloses a novel traction-type cotton harvester. This invention includes a cotton storage box, a conveyor belt, a traction frame, a cotton harvesting channel, a fixing rod, an outer protective side plate, a vehicle carrier, and an infrared sensor alarm device. The cotton storage box is perpendicular to the vehicle carrier, the cotton harvesting channel is located at the front end of the vehicle carrier, the upper end of the fixing rod is fitted into the vehicle carrier, and the lower end of the fixing rod is welded to the cotton harvesting channel. The outer protective side plate is parallel to the vehicle carrier. This novel traction-type cotton harvester incorporates an infrared sensor alarm device. When the user is harvesting cotton, the infrared sensor alarm device monitors whether the cotton storage box is full. When the cotton touches the infrared rays emitted by the infrared sensor, the infrared sensor transmits a signal to an electromagnet, energizing the electromagnet to attract a contact switch. The contact switch then triggers a buzzer to sound an alarm, indicating to the user that the cotton storage box is full. This saves time spent on manual observation and shortens the cotton harvesting time.

[0004] However, while the existing patent CN208029492U saves time for manual observation and shortens the cotton picking time, it may take a lot of time for users to install the traction frame and cotton picking entrance. Utility Model Content

The user can fix the limiting clamp on the right side of the mounting frame to the front beam of the tractor, and then use fastening screws to thread the limiting clamp and tighten it. The fastening screws press against the front beam of the tractor, which can realize the installation of the device.

[0013] Preferably, a ball nut is fixedly provided on the outer side of the ball screw, and a limit clamp is fixedly provided on the right side of the mounting bracket. The limit clamp is threadedly connected to a fastening screw. When the servo motor is started, it drives the ball screw to rotate, causing the ball nut and the limit clamp to move up and down, thereby realizing the flexible movement of the limit clamp and effectively improving the flexibility of the device.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. In this traction cotton harvester, the user pushes the traction shaft upward, and the T-shaped extrusion roller squeezes the inside of the limiting shaft. The spring contracts, and the embedding block on the right side of the cotton picking plate is embedded into the inner groove on the right side of the fixing frame. Then, the traction shaft is released, the spring returns to its original position, the T-shaped extrusion roller returns to its original position, and the embedding block is squeezed to realize the installation of the cotton picking plate.

[0016] 2. With this towed cotton harvester, the user can fix the limiting clamp on the right side of the mounting frame to the front beam of the tractor, then connect the limiting clamp with the threaded fastening screw and tighten it. The fastening screw presses against the front beam of the tractor, which can realize the installation of the device. The servo motor starts and drives the ball screw to rotate, so that the ball nut and the limiting clamp move up and down, effectively improving the flexibility of the device.
