Description

Technical Field

[0001] The invention belongs to the field of agricultural machinery, and in particular relates to a strip tillage land preparation machine with adjustable row spacing. Background Art

[0002] In the existing three-row adjustable row-spacing strip tillage machine, the hydraulic cylinder of the side tillage device is directly connected to the hydraulic pump of the walking machinery driving the adjustable row-spacing strip tillage machine, resulting in uneven pressure distribution, causing inconsistent row spacing adjustment and low adjustment accuracy.

[0003] When the transmission system of the strip tillage machine is subjected to excessive resistance, the transmission system is susceptible to damage. Summary of the invention

[0004] The purpose of the invention is to solve the problems of non-uniform adjustment of row spacing and low adjustment precision in the existing three-row strip tillage land preparation machine with adjustable row spacing.

[0005] Another object of the present invention is to solve the problem that when the transmission system of the strip tillage machine is subjected to too much resistance, the transmission system is easily damaged.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions: A strip tillage machine with adjustable row spacing comprises a middle tillage device and side tillage devices located on both sides of the middle tillage device, the side tillage devices being slidably connected to a frame via two sliding sleeves, a hydraulic cylinder being arranged between each sliding sleeve and the frame, an oil inlet pipe of each hydraulic cylinder being connected to a hydraulic synchronous shunt motor, the hydraulic synchronous shunt motor being connected to an oil outlet pipe of a hydraulic system of a traveling machine driving the strip tillage machine with adjustable row spacing, and an oil outlet pipe of each hydraulic cylinder being connected to an oil inlet pipe of the hydraulic system of the traveling machine.

[0007] A manual line spacing regulator is provided between the sliding sleeve and the frame. The manual line spacing regulator is arranged on the sliding sleeve. A scale plate is provided below the manual line spacing regulator. The scale plate is arranged on the sliding sleeve or the frame. The scale plate is used to display the adjustment accuracy.

[0008] The strip tillage machine with adjustable row spacing has a main gear box, and the output shaft of the main gear box is provided with an overload protector, which is a prior art.

[0009] Working process of the present invention: The setting of the hydraulic synchronous shunt motor can make the side tillage device synchronously adjusted, so as to make the row spacing adjustment width accurate. The adjustment range is 580mm~660mm, and the adjustment accuracy is less than 10mm. With the auxiliary manual row spacing adjuster, the adjustment accuracy can be less than 3mm.

[0010] An overload protector is provided. When the transmission system of the strip tillage machine with adjustable row spacing is subjected to excessive resistance, the overload protector can cut off the power output, thereby protecting the transmission system from damage.

[0011] Beneficial effects of the present invention: 1. The setting of hydraulic synchronous shunt motor can make the side tillage device synchronously adjusted, so as to make the row spacing adjustment width accurate. The adjustment range is 580mm~660mm, and the adjustment accuracy is less than 10mm. With the auxiliary manual row spacing adjuster, the adjustment accuracy can be less than 3mm.

[0012] 2. When the transmission system of the strip tillage machine with adjustable row spacing is subject to too much resistance, the overload protector can cut off the power output, thereby protecting the transmission system from damage. BRIEF DESCRIPTION OF THE DRAWINGS
