Description

Technical Field

[0001] This utility model relates to the field of trimmer technology, and in particular to a tracked trimmer. Background Technology

[0002] With the development of garden machinery and engineering equipment, tracked trimmers have been widely used for vegetation trimming in complex terrains such as mountains and slopes due to their excellent terrain adaptability. Traditional tracked trimmers mostly use a rigid transmission structure, resulting in insufficient coordination between their hydraulic drive system and working parts. Under prolonged high-load operation, this can easily lead to excessive hydraulic oil temperature rise and efficiency reduction. In existing technologies, engine intake systems generally use simple filter structures, which are prone to filter clogging in working environments with flying weeds and debris, leading to insufficient engine air intake and power reduction. Furthermore, hydraulic system cooling relies heavily on natural air cooling, which has low efficiency and is difficult to adapt to high-temperature conditions, frequently causing seal failures due to overheating of hydraulic components. In addition, the cooling systems of the working parts of traditional equipment are independent of the hydraulic system, failing to achieve coordinated thermal energy management, resulting in high overall energy consumption. Summary of the Invention

[0018] The following will describe in detail the embodiments of this utility model with reference to the accompanying drawings. Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0020] A tracked pruning machine includes a drive system and a working system. The drive system includes an engine 1, a triple gear pump 2, a tracked chassis 4, and a travel motor 3. Multiple travel sprockets 6 are connected to both sides of the tracked chassis 4 via support wheel connecting plates 5. Tracks 7 are tensioned between the multiple travel sprockets 6 on each side. A support plate 8 is mounted on the top of the tracked chassis 4, and the engine 1 is located in the middle of the support plate 8. The triple gear pump 2 is connected to the output end of the engine 1 on the support plate 8. A hydraulic oil tank 9 and a diesel tank 10 are respectively mounted on both sides of the triple gear pump 2 on the support plate 8. The diesel tank 10 is connected to the engine 1, and the hydraulic oil tank 9 is connected to the triple gear pump 2. A travel motor 3 is mounted on each side of the tracked chassis 4, and the triple gear pump 2 controls the travel motors via hydraulic components. 3. The output end of the reducer connected to the travel motor 3 is connected to the travel sprocket 6. The working system includes a hydraulic motor 11, a crushing shaft 12, a connecting arm 14, an accessory head cover 15, and a hydraulic cylinder 13. The front end of the support plate 8 is rotatably connected to the connecting arm 14, and the other end of the connecting arm 14 is connected to the accessory head cover 15. The crushing shaft 12 is connected to the inner two side walls of the accessory head cover 15. The hydraulic cylinder 13 is fixed to the front end of the tracked chassis 4. The telescopic end of the hydraulic cylinder 13 is connected to the lower part of the connecting arm 14 on the accessory head cover 15. The hydraulic motor 11 is fixed to the side wall of the accessory head cover 15. The hydraulic motor 11 drives the crushing shaft 12 to rotate. The hydraulic cylinder 13 and the hydraulic motor 11 are connected to the triple gear pump 2. The crushing shaft 12 is equipped with a cutter head 16.

[0021] An electrical control box 19 is installed on the support plate 8. A double proportional valve 17 and a solenoid valve group 18 are connected to the pipeline connecting the triple gear pump 2 to the walking motor 3, the hydraulic motor 11 and the hydraulic cylinder 13. The double proportional valve 17 and the solenoid valve group 18 are connected to the electrical control box 19.

[0022] The electrical control box 19 integrates a wireless communication module and a wireless remote control interface, and the electrical control box 19 is connected to a wireless remote control through the wireless remote control interface.

[0023] The output shaft of the hydraulic motor 11 is connected to a drive pulley, and the end of the crushing shaft 12 is connected to a driven pulley. The drive pulley and the driven pulley are driven by a belt.

[0024] A cyclone separator air filter 20 is provided at the air intake of the engine 1. The cyclone separator air filter 20 is fixed to the air filter bracket provided on the side of the engine 1 by a quick-release clamp.

[0025] A plate-type hydraulic oil cooler 21 is connected in series between the hydraulic oil tank 9 and the triple gear pump 2. The hydraulic oil cooler 21 is installed at an angle on the side of the support plate 8. A temperature control bypass valve is installed on the oil inlet pipe of the hydraulic oil cooler 21, and an oil temperature sensor is integrated into the oil outlet pipe of the hydraulic oil cooler 21. The temperature control bypass valve and the oil temperature sensor are connected to the overheat alarm module of the electrical control box 19. The temperature control bypass valve is connected in parallel with the double proportional valve 17. The electrical control box 19 responds first to the oil temperature signal. The oil temperature sensor is directly connected to the overheat alarm module of the electrical control box 19, so that... The electrical control box 19 can continuously monitor the actual operating temperature of the hydraulic oil flowing through the hydraulic oil cooler 21 before entering the critical components of the system. Since the temperature control bypass valve and oil temperature sensor are connected to the overheat alarm module of the electrical control box 19, the oil temperature signal is sent to a dedicated module for handling overheat alarms. This module can quickly respond to temperature anomalies. Furthermore, the temperature control bypass valve is connected in parallel with the double proportional valve 17, emphasizing that the bypass valve's control loop is physically or logically independent of the main proportional control loop, i.e., the double proportional valve 17. The logic path of the electrical control box 19 in processing the oil temperature signal and controlling the bypass valve is neither dependent on nor constrained by the complex logic or timing of processing the proportional valve control signal, thus ensuring a fast response speed.

A removable dustproof grille is provided on the front of the coolant radiator 22, and an axial flow cooling fan 23 is installed on the back.

[0027] The engine 1 of this invention is the power source for the tracked trimmer. The power generated by the engine 1 is transmitted to the triple gear pump 2, which controls the rotation of the travel motor 3 via hydraulic components. The travel motor 3 is connected to a reducer with a travel sprocket 6, which drives the track 7 to rotate, thus enabling the tracked trimmer to move. The steering system is achieved by starting and stopping the travel motors 3 on both sides.

[0028] The working system directly completes the road greening task. It consists of a hydraulic motor 11, a shredder shaft 12, a cutter head 16, and a hydraulic cylinder 13. A three-gear pump 2 controls the operation of the hydraulic motor 11 and hydraulic cylinder 13 via hydraulic components. The hydraulic motor 13 drives the shredder shaft 12 to rotate, and the hydraulic cylinder 13 adjusts the pruning angle to complete pruning operations in different scenarios. To adapt to various construction needs, the tracked pruning machine can be equipped with various attachment heads, such as those for shredding, trimming hedges, cleaning road signs, and cleaning fence panels.
