Description

Technical Field

[0001] This utility model relates to the field of mini excavator technology, specifically a protective bracket for a mini excavator. Background Technology

[0002] Mini excavators are widely used in municipal engineering, agricultural operations, and small-site construction due to their compact size and maneuverability. To ensure operator safety, mini excavators are typically equipped with protective supports to protect against flying debris, mud, and other external risks such as inclement weather during operation.

[0003] In existing technologies, such as the mini excavator protective bracket disclosed in Chinese patent CN218814003U, the height adjustment is mainly achieved through a bending structure to adapt to the protection needs of different working scenarios. However, this type of protective bracket has shortcomings in practical use:

[0004] On the one hand, its height can only be adjusted by bending. When working at night, the top of the bent support forms a void area, which cannot provide effective protection for the operator above, and is prone to dangerous situations such as falling objects injuring people.

[0005] On the other hand, the overall protection area is limited, making it difficult to fully cover the operator's work area, resulting in poor protection. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a protective bracket for mini excavators.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A protective bracket for a mini excavator includes: a bracket assembly, which is mounted on the control console base of the mini excavator. The bracket assembly includes: a rear bracket; front brackets are fixedly installed on the left and right sides of the front of the control console base of the mini excavator; the rear bracket is installed on the rear side of the control console base of the mini excavator; a protective plate is installed on the top of the rear bracket; the protective plate is fixedly connected to the left and right front brackets and the rear bracket by screws; the protective plate is provided with a lighting component, which is used by the operator to control the lights to rise at night and to control the lights to fall during the day.

[0009] The lighting assembly includes: a lamp base, a protective plate with two sets of through holes, a lamp base on the lower part of the protective plate with the through holes, a fixed bracket fixedly mounted on the lower rear side of the lamp base, a rotary motor fixedly mounted on the fixed bracket, the rotating shaft of the rotary motor being fixedly connected to a lead screw, a groove in the center of the lamp base, a lamp holder in the groove, a bulb on the front side of the lamp holder, a protrusion on the rear side of the lamp holder, a threaded hole in the center of the protrusion, and the threaded hole engaging with the lead screw.

[0010] The rotary motor is used to rotate the lead screw to raise or lower the lamp stand. The lamp stand is equipped with a battery and a wireless communication module, which is used to remotely control the bulb to start and stop.

[0011] The upper part of the left and right front brackets in the bracket assembly is equipped with a protective glass plate. The protective glass plate is equipped with a pivot on both sides. The pivot is movably connected and fixed to the two front brackets. The top of the protective glass plate is equipped with a hook-and-eye mortise and a hook-and-eye nut. The hook-and-eye mortise and hook-and-eye nut are used to temporarily fix the protective glass plate. When it is necessary to clean the protective glass plate, the hook-and-eye mortise and the protective glass plate can be flipped over for cleaning.

[0012] A support handrail is fixedly installed at the lower part of the rear support, which is used by the staff to grip and control the center of gravity.

[0013] The bracket assembly has curved handles fixed on both the left and right front brackets. The curved handles are used to install protective baffles in inclement weather.

[0014] Compared with the prior art, this utility model provides a protective bracket for a mini excavator, which has the following beneficial effects:

[0015] The lighting assembly uses a rotary motor to drive a lead screw, which in turn raises and lowers the lamp stand. During nighttime operations, the lamp stand is raised, and its bulbs provide ample illumination, filling the empty area created by structural adjustments at the top of the support frame and preventing safety hazards caused by insufficient light and gaps in protection. During daytime operations, the lamp stand is lowered, reducing interference with the operator's field of vision while maintaining the integrity of the protective structure.

[0016] The lighting components, protective panels, and support components work together in a reasonable structure to achieve the lighting function without compromising the overall protective performance of the support. The lamp stand maintains a stable connection with the support structure throughout the lifting and lowering process, further enhancing the comprehensiveness and reliability of the protection.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Reference Figures 1-6 As shown, a protective bracket for a mini excavator in this embodiment includes a bracket assembly 1, which is installed on the control console base of the mini excavator 2 to create a safe protective area for the operator.

[0026] The mini excavator 2 has front supports 101 fixedly installed on the left and right sides of the front of the control console base, and a rear support 105 installed on the rear of the control console base. The front supports 101 and the rear support 105 form a triangular support structure, improving overall stability. A protective plate 106 is installed on the top of the rear support 105. The protective plate 106 is fixedly connected to the left and right front supports 101 and the rear support 105 with screws. This connection method ensures that the protective plate 106 is firmly attached to the support, forming a top protective barrier.

[0027] A lighting component 107 is mounted on a protective plate 106. The protective plate 106 has two sets of through holes, and a lamp base 1072 is mounted on the lower part of the protective plate 106 below the through holes, providing a mounting base for the lighting component. A fixing bracket 1073 is fixedly mounted on the lower rear side of the lamp base 1072. A rotary motor 1074 is fixedly mounted on the fixing bracket 1073, and its shaft is fixedly connected to a lead screw 1075, providing power for the lifting and lowering of the lamp stand. A lamp stand 1071 is mounted in a groove in the center of the lamp base 1072. A threaded hole is located in the center of a protrusion 1076 on the rear side of the lamp stand 1071, which threadedly engages with the lead screw 1075 to achieve smooth lifting and lowering of the lamp stand 1071.

[0028] Protective glass panels 103 are installed on the upper part of the left and right front supports 101 in the bracket assembly 1. The pivots on both sides are movably connected and fixed to the front supports 101. The top fastener holes cooperate with the fastener nuts at the bottom of the protective panel 106 to realize the temporary fixing and flipping function of the protective glass panel 103. The support handrail 104 at the bottom of the rear support 105 is convenient for workers to grip, and the arc-shaped handles 102 on the left and right front supports 101 provide installation points for adding protective baffles in inclement weather.

[0029] In some examples, a wear-resistant bearing is provided at the pivot connection between the protective glass plate 103 and the front bracket 101. The wear-resistant bearing can reduce friction loss during the flipping process, extend the service life of the protective glass plate 103, and make the flipping action smoother and easier to clean.

[0030] In some examples, the outer surface of the support armrest 104 is covered with an anti-slip rubber sleeve with a textured surface to increase the friction between the hand and the armrest, so that the staff can grip firmly and effectively control the center of gravity even when their hands are wet or dirty.

[0031] In some examples, a reinforcing rib is provided at the connection between the curved handle 102 and the front bracket 101. The reinforcing rib is fixed by welding, which enhances the load-bearing capacity of the curved handle 102 and ensures that the structure remains stable after the protective baffle is installed.

[0032] In some examples, elastic washers are fitted at the connecting screws of the protective plate 106 to the front bracket 101 and the rear bracket 105. The elastic washers can buffer the stress generated by vibration, prevent the screws from loosening after long-term use, and ensure the connection reliability of the protective plate 106.

[0033] The working principle of this utility model is as follows:

[0034] When using this protective bracket for a mini excavator, first install the bracket assembly 1 on the control console base of the mini excavator 2. The front brackets 101 on the left and right sides of the control console base and the rear bracket 105 on the rear side form a stable support. The protective plate 106 is then fixedly connected to the left and right front brackets 101 and the rear bracket 105 with screws. The stability of the screw connection ensures that the protective plate 106 forms a top protective structure, creating a basic protective space for the operator.

[0035] The operation of the lighting assembly 107 is one of its core functions. Two sets of through holes on the protective plate 106 provide mounting positions for the lamp base 1072. A fixed bracket 1073 on the lower rear side of the lamp base 1072 secures a rotary motor 1074, whose shaft is connected to a lead screw 1075. The lamp holder 1071 is threadedly engaged with the lead screw 1075 through a threaded hole in the rear protrusion 1076. During nighttime operation, the rotary motor 1074 is started, driving the lead screw 1075 to rotate. Through threaded transmission, the lamp holder 1071 rises along the groove of the lamp base 1072, exposing the bulb through the through hole to provide illumination and fill any potential protective gaps at the top of the bracket. During daytime operation, the rotary motor 1074 is started in reverse, causing the lamp holder 1071 to descend and retract into the groove, protecting the bulb and providing additional protection. Simultaneously, the wireless communication module within the lamp holder 1071 can receive remote commands to control the bulb's on / off state. An internal battery provides an independent power source, ensuring normal operation even in the event of a main excavator power failure.

[0036] The protective glass panel 103 is movably connected to the front bracket 101 via two side pivots. The top latch hole engages with the latch female at the bottom of the protective panel 106 for temporary fixation, forming side protection. When the protective glass panel 103 needs to be cleaned, the latches are opened, and it can be flipped over using the pivot connection for easy cleaning. After cleaning, it can be flipped back and the latches are fastened to restore the protective function.

[0037] The handrail 104 at the lower part of the rear support 105 is provided for workers to grip when getting on and off the excavator or during operation. By applying force with their hands, workers can help control their center of gravity and improve operational safety. The arc-shaped handles 102 on the left and right front supports 101 can be used to install protective guards in inclement weather. By adapting and connecting with the guards, the side protection capability is enhanced to resist wind, rain or flying objects.

[0038] When maintenance of the protective bracket is required, components such as the protective plate 106 and the lamp holder 1071 can be easily disassembled to replace worn threaded structures, rotary motors 1074, or bulbs. Easily worn components such as the shaft connection of the protective glass plate 103 and the connection of the arc-shaped handle 102 can be inspected and repaired individually. The overall structural design facilitates maintenance, ensuring that the protective bracket maintains stable protective performance over a long period and adapts to the operational needs of mini excavators under various working conditions.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
