Problems solved by technology

At present, most of the general rice transplanting machines use a single gasoline engine or diesel engine as the power source, and the power is transmitted to the actuator through the speed change mechanism and the transmission mechanism, while the rice transplanter has many actuators, the motion state is complicated, and the problem of speed change and transmission has always been a problem. One of the difficulties in the field of agricultural machinery design and manufacturing, especially the low efficiency of small and medium power fuel engines, mechanical speed change and transmission mechanism are not easy to simplify, which makes the whole system unfavorable for low carbon energy saving and cost reduction
This patent has the following deficiencies: (1) the device uses a hydraulic cylinder as a power supply device, which is not conducive to energy saving and environmental protection; (2) how to adjust the hydraulic cylinder according to the depth of different paddy field ooze is not provided in the patent, If it is realized by artificial naked eye observation, its intelligence degree is low; (3) the device does not belong to the profiling mechanism of wheeled rice transplanter

Embodiment 1

[0028] Such as figure 1 As shown, an electric profiling mechanism of a rice transplanter includes a motor 1, a screw mandrel 7, a transmission arm 8, a water wheel support arm 5, a water wheel 6, a side ship plate 4, and a displacement sensing device, and the motor 1 is fixed On the rice transplanter frame, one end of the screw rod 7 is connected to the motor 1, and the other end is connected to the transmission arm 8; a fixing seat is arranged on the rice transplanter frame, and one end of the transmission arm 8 and the water wheel support arm 5 are all fixed on the fixed seat. On the seat, the other end of the water wheel support arm 5 is hinged with the water wheel 6; a side ship plate 4 is arranged on the rice transplanter frame, and a displacement sensing device for detecting the current side ship plate up and down displacement is arranged at the front end of the side ship plate 4, The device is connected to the motor 1 . In this embodiment, the displacement sensing devi...

Embodiment 2

[0037] This embodiment has the same structure as Embodiment 1 except for the following features: the rice transplanter has two profiling mechanisms on the left and right, and these two profiling mechanisms are jointly driven by a motor. Adjustment, but the structure is simple, can reduce machine cost, and reduce energy consumption.

[0038] The displacement sensing device is a travel switch, and the travel switch is arranged on the upper end of the displacement transmission mechanism 3. When the displacement of the side ship plate 4 exceeds the value set by the forming switch, the motor is triggered to perform corresponding operations.

Abstract

The invention discloses electric profiling mechanisms of a paddy rice transplanter. The invention relates to the field of paddy rice transplanter apparatus researches. Existing hydraulic profiling mechanisms of double-wheel 4-row automatic paddy rice transplanters have problems such as complicated mechanism and low efficiency. Also, existing hydraulic profiling mechanisms can not be adapted to complicated paddy field environments with deep mud. The profiling mechanisms provided by the invention are based on an electric paddy rice transplanter. A left profiling mechanism and a right profiling mechanism are independently driven by 2 motors, such that the transplanters can keep balanced with a mud surface in a paddy field with an uneven hardground, and transplanting quality can be ensured. Profiling driving motors have a self locking function in a shut-down situation. For saving energy, the motors are in a standby state when not triggered. Also, a manual adjusting function is provided. Adriving mechanism of the mechanical hydraulic profiling mechanisms is simplified to a large extent, the volume of the transplanter is reduced, and the weight of the transplanter is reduced.

Description

technical field [0001] The invention relates to the field of rice transplanter research, in particular to an electric profiling mechanism of a rice transplanter. Background technique [0002] Rice is the grain crop with the largest planting area, the highest yield per unit area, and the largest total yield in my country. Its output ranks first in the world. 60% of the population in China takes rice as the staple food. Rice plays a pivotal role in my country's grain production. Therefore, rice Production mechanization is of great significance. At present, most of the general rice transplanting machines use a single gasoline engine or diesel engine as the power source, and the power is transmitted to the actuator through the speed change mechanism and the transmission mechanism, while the rice transplanter has many actuators, the motion state is complicated, and the problem of speed change and transmission has always been a problem. It is one of the difficulties in the field o...
