Description

Technical Field

[0001] The utility model relates to the field of micro-tillage machines, and more specifically, to a micro-tillage machine with storable rear wheels. Background Art

[0002] The micro-tillage machine is powered by a small diesel engine or gasoline engine, and has the characteristics of light weight, small size, simple structure, etc. It is a small machine for tilling the land;

[0003] After searching, the existing patent (publication number: CN205993105U) discloses a ginger harvester with a vibration reduction function, including a frame and a rear wheel arranged at the rear of the frame, a micro-tillage machine with a front wheel is arranged in front of the frame, and a digging shovel for digging ginger in the soil is arranged on the front side of the frame. Two convex guide bars parallel to the bottom edge of the shovel for contacting with the soil are arranged on the lower middle side of the outer wall of the digging shovel, and the convex guide bars are provided with a pointed wedge-shaped surface at the front end. A plurality of sand discharge holes are staggered and evenly distributed on the outer wall of the digging shovel above the convex guide bars. The digging shovel is connected to the front rocker arm through a connecting rod, and the front rocker arm is hinged to the frame and driven to swing by a driving device. A separation screen is arranged behind the digging shovel. By designing a mechanism with active vibration reduction, the ginger harvester can not only separate ginger and soil blocks through the vibration of the screen body, but also offset the inertial forces of the vibration mechanism during the reciprocating motion through the mechanism design to reduce mechanical vibration. The convex guide bar can make the digging shovel shovel into the soil more easily and smoothly, and the sand discharge hole can achieve preliminary sand discharge. In the process of realizing the utility model, the inventor found that the prior art has the following problems:

[0004] The existing micro-tillage machine is a tool for turning the soil, and is small in size and can be operated by one person. The rear end of the existing micro-tillage machine usually has wheels to assist the micro-tillage machine to move in the field. When turning the soil in the paddy field, the rear wheel is easy to fall, which makes it inconvenient to turn the soil. The traditional rear wheel is relatively complicated to disassemble, so a disassembly mechanism is required to facilitate the disassembly of the rear wheel. At the same time, the above-cited patent document does not propose a relevant solution to solve the problem of disassembly of the rear wheel of the micro-tillage machine;

[0005] Therefore, in view of the above problems, a micro-tillage machine with storable rear wheels is proposed. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the utility model provides a micro-tillage machine with foldable rear wheels to solve the problems raised in the above-mentioned background technology.

[0007] To achieve the above object, the utility model provides the following technical solution: a micro-tillage machine with foldable rear wheels, comprising a frame, a disassembly mechanism fixedly connected to the bottom end of the frame, the disassembly mechanism comprising a fixing rod, one end of the fixing rod fixedly connected to a limiting sleeve, a fixing bolt passing through the inner wall of the limiting sleeve, and a connecting rod movably connected to the inner wall of the limiting sleeve;

[0008] A fixing hole is provided on the connecting rod, one end of the connecting rod is fixedly connected to a connecting shaft, one end of the connecting shaft is connected to a roller through a bearing, the bottom end of the fixing rod is fixedly connected to a storage sleeve, and the fixing rod is fixedly installed on the bottom end of the frame.

[0009] Preferably, a push rod is fixedly connected to the upper end of the frame, a transmission mechanism is fixedly connected to the upper end of the frame, a tillage assembly is fixedly connected to the bottom end of the frame, and a mud guard mechanism is fixedly connected to the bottom end of the frame.

[0010] Preferably, the fixing holes are evenly arranged on the connecting rod, and the fixing bolts penetrate the limiting sleeve and the interior of the fixing holes.

[0011] Preferably, the size of the limiting sleeve is the same as that of the storage sleeve, and a hole is formed on the upper surface of the storage sleeve.

[0012] Preferably, the mud guard mechanism includes a fixed block, and the outer wall of the fixed block is connected to a mud guard via a rotating shaft.

[0013] Preferably, a movable block is fixedly connected to the outer wall of the mudguard, the outer wall of the movable block is connected to a pull rod via a bearing, and the upper end of the pull rod is connected to a movable shaft via a bearing.

[0014] Preferably, a movable groove is opened on the upper surface of the vehicle frame, the movable shaft is arranged inside the movable groove, and a fixed baffle is fixedly connected to the bottom end of the inner wall of the movable groove.

[0015] Preferably, a limit baffle is fixedly connected to the inner wall of the movable groove, and the upper right side of the limit baffle is protruding.

[0016] Technical effects and advantages of the utility model:

[0017] 1. Compared with the prior art, the micro-tillage machine with storable rear wheels is easy to disassemble and store through a disassembly mechanism. When in use, the connecting rod can be removed from the limiting sleeve and then fixed on the storage sleeve, so that the micro-tillage machine can be easily moved in the paddy field, and the rear wheel is fixed on the storage sleeve to prevent it from being left behind and lost. When in use, the height of the roller can be adjusted through the fixing hole, so that it can be adjusted according to the needs of the farmland, which is more convenient to use.

[0018] 2. Compared with the prior art, this micro-tillage machine with foldable rear wheels is easy to clean through the mud guard mechanism, movable groove, limit baffle and fixed baffle. The mud guard can be used to prevent the splashing of turned over mud. While blocking, more mud will accumulate on the mud guard. At this time, the mud guard can be lifted up through the movable shaft, and then the inside of the mud guard can be cleaned, which solves the problem of inconvenient cleaning of traditional mud guards and the impact of mud accumulation on the equipment.
