Abstract
Description
Technical Field
[0001] This utility model relates to the field of agricultural machinery technology, and in particular to a self-propelled composite planting hole digger. Background Technology
[0002] To improve the efficiency of vegetation planting, hole digging machines are usually used to drill holes, making it easier for people to plant plants manually.
[0003] Currently, traditional self-propelled hole diggers mainly consist of a walking mechanism and rotary tillers. For example, patent number CN101940097 A, patent name is a hole digger that is matched with a hand tractor. In this patent, the walking mechanism walks on the ground to be cultivated, and the rotary tillers rotate at all times to dig holes while the walking mechanism is walking.
[0004] However, the aforementioned walking mechanism and rotary tillage blades cannot work in sync, resulting in inconsistent spacing between adjacent tillage points and affecting subsequent tillage operations.
[0005] Therefore, how to design a self-propelled composite planting hole digging machine with a simple structure, low cost, and uniform spacing is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content
[0006] This utility model provides a self-propelled composite planting hole digging machine, which solves the technical problem of inconsistent spacing between adjacent holes in existing hole digging machines.
[0007] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: a self-propelled composite planting hole digging machine, comprising: a walking mechanism and an indirect lifting mechanism.
[0008] The traveling mechanism includes a frame, a rear axle, and a traveling motor. The rear axle is fixed to the frame and has wheels driven to both ends. The traveling motor is fixed to the frame and its first output shaft is driven to the input shaft of the rear axle. The indirect lifting mechanism includes a rotary wheel, a crankshaft, and a drill. The rotary wheel rotates on the frame about an axis perpendicular to the height of the frame and is driven to the second output shaft of the traveling motor via a belt. One end of the crankshaft is driven to the rotary wheel. The drill is arranged along the height of the frame and its top end is hinged to the journal of the crankshaft so as to move indirectly up and down with the rotation of the rotary wheel.
[0009] The beneficial effects of this utility model are: it improves the mechanism of the traditional self-propelled hole digger. First, the walking motor drives the two wheels to rotate through the rear axle, which drives the frame to move on the ground to be cultivated. Then, the rotating wheel is connected to the walking motor through the belt. Since the crankshaft is connected to the rotating wheel and the drill is hinged on the crankshaft journal, it can be indirectly raised and lowered while the frame is moving, ensuring that the distance between two adjacent holes is the same.
[0010] Based on the above technical solution, the present invention can be further improved as follows.
[0011] Furthermore, the crankshaft includes a first rotating shaft, a turntable, and a second rotating shaft. One end of the first rotating shaft is drivenly connected to the turntable. One side of the turntable is concentrically fixed to the other end of the first rotating shaft. The second rotating shaft is the journal of the crankshaft, and one end of it is eccentrically drivenly connected to the other side of the turntable. The drilling rig is hinged to the second rotating shaft.
[0012] Furthermore, the drilling rig includes a drilling motor and a auger shaft. The housing of the drilling motor is hinged to the journal of the crankshaft, and its output shaft is arranged along the height direction of the frame. The auger shaft is arranged along the height direction of the frame and is drively connected to the output shaft of the drilling motor.
[0013] The further beneficial effect of adopting the above is that by using a drilling motor to drive the spiral shaft to rotate, rapid drilling can be achieved on the land to be cultivated.
[0014] Furthermore, it also includes a slider, wherein the frame is provided with a groove arranged along its height direction; the slider is fixed to the drilling motor and slides within the groove.
[0015] The further beneficial effect of adopting the above is that by fixing the slider on the drilling motor and sliding it in the groove, the upward and downward movement direction of the drilling motor can be guided.
[0016] Furthermore, it also includes handrails, which are fixed to the vehicle frame. Attached Figure Description
