Abstract
Description
Technical Field
[0001] The utility model relates to farmland irrigation equipment, in particular to a linear travel protection device for a translation type sprinkler irrigation machine. Background Art
[0002] At present, with the development of agriculture, horizontal sprinkler irrigation machines are becoming more and more popular. In order to keep the horizontal sprinkler irrigation machine moving in a straight line, the existing technology is to set the GPS navigation equipment on the tower vehicle. However, the limitations of GPS navigation itself are difficult to eliminate for the time being, such as the influence of the environment, the reception of signals must be unobstructed in an open area, otherwise it will affect the positioning accuracy; weather factors, such as sunspots, reduce the strength of signal reception and affect positioning; interference from external satellites, etc. The defects of such equipment are: once the positioning signal is poor, it will cause very large interference to the normal operation of the horizontal sprinkler irrigation machine, and in serious cases, it will cause damage to the equipment. Summary of the invention
[0003] The technical task of the utility model is to address the shortcomings of the above status quo and provide a linear travel protection device for a translational sprinkler irrigation machine which can keep the device moving in a straight line when there is no GPS signal.
[0004] The utility model solves the technical problem by adopting the following technical solution: a linear travel protection device for a translational sprinkler irrigation machine includes a left tire group and a right tire group of a tower vehicle. The left tire group is connected to the left reducer by bolts, and the left reducer is connected to the tower vehicle chassis by bolts; the right tire group is connected to the right reducer by bolts, and then connected to the tower vehicle chassis by bolts. The GPS main control box is fixed to the tower vehicle chassis by angle irons. The support rod assembly is fixed to the tower vehicle chassis by U-bolts. The boom assembly is clamped on the support rod assembly by the U-plate on the component and then fastened by bolts, and the float type travel switch is also fixed to the boom assembly by bolts. The control line of the float type travel switch is connected to the GPS main control box.
[0005] There are two float type travel switches, which are respectively arranged on the left and right inner wall sides of the water channel.
[0006] Compared with the prior art, the utility model of a linear travel protection device for a translational sprinkler has the following characteristics: the utility model sets a float type travel switch so that the translation machine can self-correct when the device is triggered during the linear travel process. The device can maintain the normal operation of the equipment for a short time and return to the GPS navigation state when the signal is normal; by setting a support rod assembly, the equipment cost can be low and the installation is convenient.

[0011] A linear travel protection device for a translational sprinkler is described in detail below with reference to the accompanying drawings of the specification.
[0012] The utility model discloses a linear travel protection device for a translation type sprinkler irrigation machine, and the structure includes components such as a left tire group 1 of a tower vehicle. The left tire group 1 is connected to the left reducer 9 by bolts, and the left reducer 9 is connected to the tower vehicle chassis 8 by bolts; the right tire group 3 is connected to the right reducer 10 by bolts, and then connected to the tower vehicle chassis 8 by bolts. In this way, a movable chassis vehicle is formed. The GPS main control box 2 is fixed to the tower vehicle chassis 8 by angle iron. The support rod assembly 4 is fixed to the tower vehicle chassis 8 by U-bolts. The suspension rod assembly 5 is clamped on the support rod assembly 4 by the U-plate on the component and then fastened by bolts, and the float type travel switch 6 is also fixed to the suspension rod assembly 5 by bolts. The suspension rod assembly 5 is easy to install and plays a role in assisting the operation of the control equipment. The control line of the float type travel switch 6 is connected to the GPS main control box 2.
[0013] There are two float type travel switches 6, which are respectively arranged on the left and right inner wall sides of the water channel 7. The use of the float type travel switch 6 effectively eliminates the instability of GPS signal reception and improves the reliability and safety of equipment operation.
[0014] During operation, the GPS main control box 2 receives signals to control the normal operation of the equipment, drives the left reducer 9 to drive the left group of tires 1 and the right group of tires 3 to push the tower car chassis 8 forward at the same time. The support rod assembly 4, the suspension rod assembly 5, and the float type travel switch 6 are in the normal installation position of the water channel 7 and also follow the tower car forward. When the GPS main control box 2 receives a weak or no signal, it will cause the tower car to deviate from the normal walking route, causing the equipment to no longer run in a straight line. In serious cases, the float of the float type travel switch 6 contacts the wall of the water channel 7, triggering the action signal to be transmitted to the GPS main control box 2. The GPS main control box 2 adjusts the tower car after receiving the travel switch signal. For example, when the left float type travel switch 6 contacts the wall of the left water channel 7, the left group of tires 1 is fine-tuned to run to the right, while the right group of tires 3 stops running and is forcibly pushed to the right by the tower car. Through gradual adjustment, the left float type travel switch 6 and the wall of the left water channel 7 are gradually kept in a disengaged state until the GPS main control box 2 can normally receive the GPS signal. For the normal and safe operation of the equipment, the protection device can only work within a set period of time. If the GPS main control box 2 still cannot receive the GPS signal within the set time, it will be forced to shut down and send a fault signal to the APP or the central control room, waiting for maintenance.
[0015] The utility model has low cost and is easy to install. When the GPS signal is not good, the translation machine can correct itself in the process of straight line walking, which makes up for the defects of GPS automatic control operation. It is conducive to the vigorous promotion and application of translation type sprinkler irrigation machines with GPS automatic control equipment, and solves the worries of users.
