Description

Technical Field

[0001] The invention relates to the technical field of grain dryer production equipment, in particular to a gear height adjusting device. Background Art

[0002] A grain dryer is a type of drying equipment used to dry grain. It can kill insect eggs and dry grain through high-temperature treatment. Grain dryers often require the installation of a height adjustment device that matches the drum that loads grain. This device facilitates the lifting and tilting of the drum so that the dried grain can be unloaded. However, this type of height adjustment device still has some defects during actual operation.

[0003] The height adjustment device can often only realize a single height adjustment function, which is not easy to meet the needs of the grain dryer drum to move up and down to improve the internal grain movement and drying uniformity, which leads to the low practicality of the device. In addition, it is not easy to intelligently monitor the stress condition of the early warning device, which makes the device prone to overload and damage, and improves the safety performance of the device during operation. Based on this, we propose a new gear height adjustment device. Summary of the Invention

[0004] The purpose of the present invention is to provide a gear height adjustment device to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a gear height adjustment device, comprising a housing and a height adjustment frame, a servo motor being installed at one end of the housing, an eccentric shaft being connected to the inside of the housing at the output end of the servo motor, the eccentric shaft being connected to a planetary gear assembly via a rotating shaft, the planetary gear assembly being connected to a movable rod via a rotating shaft, the movable rod being movably connected to a connecting slider via a rotating shaft, a transmission member being slidably connected to the movable rod, a connecting sliding cavity matching the connecting slider being provided on the transmission member, the height adjustment frame being welded to the top of the transmission member, a pressure sensing seat being welded at one end of the height adjustment frame, a buzzer alarm being installed on the outer wall of the pressure sensing seat, and an external arm being installed on the pressure sensing seat.

[0007] Preferably, one end of the height adjustment frame passes through the casing and extends to the outside, and one end of the casing is evenly provided with a strip-shaped limiting opening that is slidably connected to the height adjustment frame.

[0008] Preferably, a mounting base is installed on the top of the pressure sensing seat, a snap-fit ​​connection is formed between the outer arm and the mounting base, and screws are evenly arranged between the outer arm and the mounting base.

[0009] Preferably, a pressure sensor matching the assembly base is installed at the bottom end of the pressure sensing seat, so as to facilitate real-time monitoring of the weight of the assembly base, the external arm and the grain dryer drum installed thereon.

[0010] Preferably, an outer side wall of the outer arm is vulcanized with a non-slip rubber layer, and fixing screw holes are evenly arranged on the edge of the outer arm.

[0011] Preferably, a reserved sleeve is uniformly welded to the inner side wall of the casing, and a sliding connection is formed between the reserved sleeve and the transmission member.

[0012] Preferably, a positioning piece is provided at the bottom end of the interior of the casing, and a laser ranging sensor matching the positioning piece is installed at the bottom of the transmission member, so as to facilitate intelligent control of the lifting height of the grain dryer drum.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] (1) The gear height adjustment device optimizes its own performance by installing a servo motor and an eccentric shaft, etc. On the one hand, the servo motors on the two sets of housings are started synchronously to drive the eccentric shaft to rotate, and then drive the planetary gear assembly movably connected to the tail end of the eccentric shaft to rotate, thereby driving the transmission member on the movable rod movably connected to the planetary gear assembly to move up and down. At this time, the up and down reciprocating transmission mechanism inside the two sets of housings can drive the grain dryer drum loaded with grain to move up and down, which is convenient for driving the grain inside the grain dryer drum to move and is conducive to sufficient drying of the grain. On the other hand, starting the servo motor on a separate housing can drive the grain dryer drum installed with two external arms to adjust the height and tilt, so that the dried grain can be easily unloaded through the tilt adjustment setting;

[0015] (2) The gear height adjustment device is equipped with a pressure sensing seat, etc., so that the device optimizes its own structure. On the one hand, a pressure sensing seat is welded at one end of the height adjustment frame, and a buzzer alarm is installed on the outer wall of the pressure sensing seat. The pressure sensing seat equipped with a pressure sensor can intelligently monitor the stress of the external arm and send the monitored data to the external control device. When the stress value exceeds the preset safety value, the buzzer alarm will sound an alarm to remind the user to reduce the amount of grain to be dried to avoid the device from breaking or being damaged, which improves the safety performance of the device. On the other hand, an assembly base is installed on the top of the pressure sensing seat, and the external arm and the assembly base are set to be connected in a snap-fit ​​connection, and screws are evenly arranged between the external arm and the assembly base, which makes it easy to flexibly replace the external arm according to the installation needs of the grain dryer drum, thereby enhancing the applicability.

[0016] (3) The gear height adjustment device is equipped with a laser distance sensor and a housing, so that when the device is in use, when the transmission member drives the external arm and the grain dryer drum installed thereon to move up and down, the distance between the laser distance sensor installed at the bottom of the transmission member and the positioning piece set at the bottom end of the housing will change in real time. The laser distance sensor can monitor this distance change in real time and then transmit it to the external control device. After the internal program of the external control device performs calculation processing, the height adjustment height of one end of the grain dryer drum can be automatically calculated, thereby facilitating intelligent control of the lifting height of the grain dryer drum, which is convenient for automatic and precise control of the tilt height of the unloading material.
