Description

Technical Field

[0001] The utility model relates to an agricultural machine, in particular to a strip tillage machine with quick disassembly and assembly. Background Technique

[0002] In recent years, the area of corn planted using conservation tillage technology in China has gradually increased, and the straw row-forming strip tillage technology has also been continuously accepted by the majority of farmers. More and more farmers have adopted this agronomy. The straw row-forming strip tillage technology meets the requirements of retaining straw, improving soil fertility, and making the seedbed flat, meeting the agronomic requirements of being loose on the top and solid on the bottom, ensuring the emergence rate. However, for the existing strip tillage machine, the cutter shaft is connected to the side box. If the cutter shaft is damaged, the side box must be removed and the gear taken off to replace the cutter shaft, which is very time-consuming and laborious. Precious farming time is wasted. If too much time is spent on repairing the machine, the farming time may be missed. For the existing 3-row strip tillage machine, the hydraulic pump is a 3-way hydraulic pump connected behind the main gearbox. Since the 3-way hydraulic pump is prone to damage and if one of them is damaged, the whole 3-way hydraulic pump cannot be used. To solve the above problems, the strip tillage machine with quick disassembly and assembly provided by the utility model uses an integrally welded side box and a quick plug-in cutter shaft to solve the problems of difficult side box maintenance and difficult cutter shaft replacement. An additional horizontal shaft is added to the main shaft box, and the output shaft of the hydraulic pump behind the main shaft box is changed to output at both the left and right ends. A 2-way hydraulic pump is installed on the left side and a single hydraulic pump is installed on the right side. In this way, the problem of easy damage of the 3-way hydraulic pump is solved. Even if one of the single hydraulic pump and the 2-way hydraulic pump is damaged, it can be quickly replaced, perfectly solving the above problems. Content of the Utility Model

[0003] The purpose of the utility model is to provide a strip tillage machine with quick disassembly and assembly to solve the problems raised in the above background technique.

[0004] To solve the above technical problems, the utility model provides the following technical solution: A strip tillage machine with quick disassembly and assembly, including a main shaft box, a main frame, a lower suspension frame, an upper suspension frame, a subsoiler, a subsoiler seat, a weed wheel frame, a weed wheel, a depth limiter wheel, a side plate, an integrally welded side box, a universal joint coupling, a secondary beam, a radiator, a fuel tank, a 2-way hydraulic pump, a press roller support, a press roller drive hydraulic motor, a press roller, a soil covering disc seat, a soil covering disc, a cutter roller, rotary tillage knives, a single hydraulic pump, an intermediate side vertical box, a side box upper transmission shaft, a side box cutter roller transmission shaft, a cutter roller spline sleeve, a cutter roller bearing seat. It is characterized in that the strip tillage machine with quick disassembly and assembly has an integrally welded side box, which is directly fixed to the side plate with bolts. If the gears and bearings inside the box are damaged, they can be conveniently disassembled and replaced as a whole, greatly shortening the repair time and saving farming time for users.

[0005] The cutter shaft connected to the integrally welded side box further has a cutter roller spline sleeve, which is directly matched with the cutter roller transmission shaft of the side box. On the other side of the cutter roller is a cutter roller bearing seat, which is connected to the side plate, making it convenient to install the cutter roller. If the cutter roller is damaged, the new cutter roller to be replaced can be directly inserted into the cutter roller transmission shaft of the side box, and the cutter roller bearing seat is connected to the side plate, achieving quick disassembly and assembly.

[0006] Furthermore, a transverse shaft is added to the main spindle box. The original triple hydraulic pump connected at the back of the main spindle box is replaced by a single hydraulic pump and a double hydraulic pump connected respectively on the left and right, which improves the service life of the hydraulic pump. Moreover, if one of the hydraulic pumps breaks down, only that one needs to be replaced instead of replacing the entire triple hydraulic pump at once. The single hydraulic pump and the double hydraulic pump are inexpensive and easy to purchase, which also reduces the economic losses of farmers. BRIEF DESCRIPTION OF THE DRAWINGS
