Abstract
Description
Technical Field
[0001] This utility model relates to seedling transplanting, and in particular to a ridge height adaptive adjustment punching device suitable for hilly and mountainous operations, with high passability and stability. Background Technology
[0002] With the continuous development of productivity and the advancement of technology, mechanized and automated transplanting has become a development trend and is gradually replacing traditional manual transplanting. Well-cellar transplanting, as a newly emerging seedling transplanting technology in recent years, can achieve early and rapid seedling growth, provide a suitable temperature and humidity environment for growth, improve the survival rate of tobacco seedlings after transplanting, and significantly reduce farmers' production costs. However, most existing wheeled transplanters are suitable for plains areas and are prone to slippage, excessively large turning radii, and poor maneuverability and unstable well-cellar hole quality during operation in hilly and mountainous areas. On the other hand, hole drilling is the most critical step in well-cellar transplanting, and the quality of the drilled holes directly affects seedling growth. However, due to the uneven ridge height caused by manual ridging and ridging machines in hilly and mountainous areas, the depth of the wells drilled by the transplanting drilling device is inconsistent, failing to meet the agronomic requirements of well-cellar transplanting. Summary of the Invention

[0018] Example 1: A ridge height adaptive adjustment perforation device includes a ridge height adaptive adjustment mechanism, a tracked chassis, a perforation mechanism, a lifting mechanism, a PLC control box, and a battery. The lifting mechanism is fixed inside the tracked chassis, the ridge height adaptive adjustment mechanism is installed at the front end of the lifting mechanism, the perforation mechanism is installed in the middle of the lifting mechanism, and the PLC control box and battery are installed on the tracked chassis.
[0019] The lifting mechanism includes an upper frame, a lower frame, scissor arms, and hydraulic push rods. The upper frame and the lower frame are arranged in parallel. Two sets of scissor arms are symmetrically arranged on both sides between the upper frame and the lower frame, and both are connected to the upper frame and the lower frame. The four ends of the two sets of scissor arms are connected and stabilized by connecting rods. Two hydraulic push rods are installed at both ends of the connecting rod at the lower front end of the scissor arms through lifting lugs. The upper end of the hydraulic push rods is connected to the scissor arms through lifting lugs.
[0020] The ridge height adaptive adjustment mechanism includes a pressure roller, a connecting rod, a hinge, an adjustment fixing frame, and a displacement sensor. The connecting rod is horizontally L-shaped and includes a horizontal bar and a vertical bar. The end of the horizontal bar is connected to the front end of the lower frame through a hinge, and the pressure roller is installed at the bottom end of the vertical bar. The adjustment fixing frame is vertically installed at the front end of the lower frame and is located above the horizontal bar of the connecting rod. The displacement sensor is fixed on the adjustment fixing frame and its bottom probe is in contact with the upper surface of the horizontal bar.
[0021] The drilling mechanism includes a drill bit, a drilling bracket, a drilling motor, and a coupling. The drilling bracket is fixed at the center of the upper frame, the drilling motor is fixed at the lower part of the drilling bracket, and the drill bit is located below the drilling motor and connected to the rotating shaft of the drilling motor through the coupling.
[0022] The PLC controller is connected to the displacement sensor, hydraulic push rod, and punching motor via data cables, and is also connected to the battery via wires.
[0023] The tracked chassis also includes a travel motor, a drive sprocket, a driven sprocket, and a transmission chain. The travel motor is located on the upper part of the tracked chassis. The drive sprocket is mounted on the shaft of the travel motor, and the driven sprocket is mounted on the shaft of the tracked chassis. The drive sprocket and the driven sprocket are linked by a transmission chain. The travel motor is connected to a battery via wires and to a PLC controller via a data cable. Slide grooves are provided on the inner walls of both sides of the upper and lower frames. A pulley is installed on the outside of the scissor arm end, and this pulley is installed in the slide groove and slides along the groove.
[0024] After the device is started, the battery powers the walking motor, which transmits power to the tracked chassis via chain drive, enabling the machine to move forward at a constant speed. During travel, the pressure roller of the ridge height adaptive adjustment mechanism remains in contact with the ridge surface. When the device reaches the designated drilling position, the ridge height adaptive adjustment mechanism detects the vertical change of the pressure roller through a displacement sensor. This value is then used as the retraction amount of the hydraulic push rod of the lifting mechanism, determined by the length of the vertical rod and the angle of the hydraulic push rod. The Delta / AS228T-A PLC controller controls the vertical displacement of the scissor arm based on the retraction amount, thereby controlling the drilling depth of the drill bit. Once the drill bit has penetrated a certain depth, the push rod immediately returns to its original position, and the device continues to travel the same distance at a constant speed, repeating the above actions to complete the intermittent drilling operation.
[0025] The PLC controller can also be connected wirelessly to the matching Xiaolong / SMC60A control handle for remote manual control, resulting in more precise operation and better drilling results.
