DETAILED DESCRIPTION

[0037] The technical solution of the utility model will be described clearly and completely below in conjunction with specific embodiments. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0038] The utility model embodiment specifically provides a trenching device, please refer to Figure 1 , including an electric push rod 1, a slider 2, a fixing seat 3, a ditching mechanism 4 and a transmission rod 5.

[0039] Among them, a slider 2 is fixed at the bottom of the electric push rod 1, and the slider 2 is driven by the electric push rod 1 to achieve linear movement. The outer side of the fixed seat 3 is fixed to the electric push rod 1. The electric push rod 1 is fixed to the external trenching equipment through the fixed seat 3, so that the electric push rod 1 can be connected and fixed with the external trenching equipment to facilitate the control and use of the external trenching equipment.

[0040] Furthermore, the trenching mechanism 4 is arranged outside the electric push rod 1, and the two ends of the transmission rod 5 are respectively fixed to the trenching mechanism 4 and the slider 2, and the transmission rod 5 is an angle iron structure as a whole, and the bottom of the slider 2 is fixed to the transmission rod 5, so that the trenching mechanism 4 is driven to move when the slider 2 is displaced, so as to realize the quick adjustment of the trenching depth, and the electric push rod 1 adjusts the working position of the trenching mechanism 4 according to the needs to realize trenching of different depths;

[0041] Specifically, the trenching mechanism 4 includes a fixing sleeve 41 fixed to the transmission rod 5 on the outside, a first motor 42 fixedly connected to the fixing sleeve 41 at the bottom, and a trenching drill 43 rotatably mounted on the fixing sleeve 41 at the top. The output shaft of the first motor 42 is inserted into the fixing sleeve 41 and is coaxially fixed with the trenching drill 43, so that when the first motor 42 is energized, it can drive the trenching drill 43 to rotate to dig the soil. At the same time, driven by the movement of the trenching equipment, the trenching drill 43 gradually moves in a straight line and digs the required field trenches, so that according to different terrains, the trenching drill 43 can flexibly move and adjust the excavation height to adapt to the undulating conditions of the ground and improve the use function.

[0042] Further, as another implementation method that can be implemented in this technical solution, please refer to Figure 1 The ditching device also includes a first synchronous frame 6 and a load-reducing component 7.

[0043] During implementation, although the trenching equipment uses the trenching drill 43 to dig the damaged soil, it is more convenient to move the equipment to trench. However, since the trenching drill 43 is entirely attached to the electric slide rail 1 for fixed force, during the trenching process, the trenching resistance is only borne by the electric push rod 1, which can easily cause the components of the electric push rod 1 to be loaded, accelerate the loss and affect the life. Therefore, by providing the first synchronous frame 6 and the load-reducing component 7, the resistance during trenching can be transmitted synchronously to reduce the force on the electric push rod 1, which is beneficial to the stability of trenching and improves the life.

[0044] Among them, the first synchronous frame 6 is fixed on the upper surface of the transmission rod 5, and the load-reducing component 7 is fixed to the outer side of the fixed seat 3. During the trenching operation, the load-reducing component 7 is fixed to the first synchronous frame 6 so that the trenching pulling force on the electric push rod 1 can be synchronously transmitted to the load-reducing component 7 to bear the force, so that the electric push rod 1 can reduce the force.

[0045] For details, please refer to Figure 2The first synchronous frame 6 includes a strip plate 61 whose bottom is vertically fixed to the surface of the transmission rod 5 and a first anti-skid pattern 62 integrally fixed to the outer side of the strip plate 61, so as to improve the contact friction with the load-reducing component 7 through the first anti-skid pattern 62.

[0046] The strip 61 extends along the length direction of the transmission rod 5, and the first anti-slip grooves 62 are arranged at intervals along the length direction of the strip 61, so that when the transmission rod 5 slides linearly along the surface of the electric push rod 1 driven by the sliding of the slider 2, the strip 61 and the first anti-slip grooves 62 can also move synchronously, so as to be conveniently connected to the load-reducing component 7 at any time.

[0047] For further information, please refer to Figure 2 The load-reducing component 7 includes a protective shell 71 fixed on the fixing seat 3 on the back side, a synchronous component 72 slidably connected to the protective shell 71 on the top, a second motor 73 fixed to the protective shell 71 on the outside, and a driving component arranged in the protective shell 71. The output shaft of the second motor 73 penetrates the protective shell 71 and is connected to the driving component. The top of the synchronous component 72 is connected to the driving component to drive the synchronous component 72 to connect and separate with the first synchronous frame 6 through the driving component, so that when the trenching operation is not performed, the synchronous component 72 can be separated from the strip 61. When trenching is to be performed, the synchronous component 72 is fixed to the strip 61, so that the trenching resistance on the strip 61 can be partially transmitted to the synchronous component 72 for force, thereby reducing the force on the electric push rod 1.

[0048] For details, please refer to Figure 3 The synchronization component 72 includes a side plate 721 fixed to the surface of the protective shell 71, a guide rod 722 with both ends vertically fixed to the side plate 721, a second synchronization frame 723 slidably connected to the guide rod 722 at the top, and a spring 724 arranged between the contact surfaces of the side plate 721 and the second synchronization frame 723. The spring 724 is coaxially arranged on the outside of the guide rod 722, and the spring 724 is in a compressed state when it is normal, so that the second synchronization frame 723 can be pushed out in the direction of the strip plate 61 at any time.

[0049] Among them, the number of second synchronous frames 723 is set at two, and the second synchronous frames 723 are mirror-distributed with the strip plate 61 as the mirror axis. The second synchronous frame 723 is fixed with a second anti-slip pattern 725 on the inner side. The first anti-slip pattern 62 and the second anti-slip pattern 725 are both protruding vertical pattern structures to facilitate increasing the friction force when the second synchronous frame 723 contacts the strip plate 61. When the second synchronous frame 723 is placed daily, there is a gap between it and the strip plate 61, so that the strip plate 61 can avoid contact with the second synchronous frame 723 when moving, thereby avoiding inconvenience in adjusting the position of the trenching drill 43.

[0050] Among them, a slide rail 711 is provided at the bottom of the protective shell 71, and a slide frame 726 is fixedly installed on the top of the second synchronous frame 723. The second synchronous frame 723 is slidably connected to the slide rail 711 through the slide frame 726. The slide frame 726 can only slide in a straight line along the slide rail 711, so that the two second synchronous frames 723 can slide towards or away from each other along the slide rail 711 through the slide frame 726. When trenching, the second synchronous frame 723 clamps the strip 61 to share the trenching resistance. After trenching is completed, the second synchronous frame 723 can be separated from the strip 61 to facilitate the subsequent operation of adjusting the position of the trenching drill 43.

[0051] Furthermore, the top of the slide 726 is fixedly connected to the force-bearing frame 727, and the driving assembly includes a push block 74 rotatably connected to the protective shell 71 at the rear and a transmission block 75 coaxially fixed to the second motor 73 at the center. The transmission block 75 is embedded and fixed in the push block 74, and the left and right ends of the push block 74 are in contact with the force-bearing frame 727, so that in daily use, the push block 74 can push the force-bearing frame 727 to enable the two second synchronous frames 723 to move away from each other.

[0052] The push block 74 includes a rotating frame 741 rotatably mounted on the inner wall of the protective shell 71, a mounting groove 742 coaxially opened on the front side of the rotating frame 741, and tooth grooves 743 arranged in an array along the circumferential direction of the mounting groove 742. The inner side of the force frame 727 is in contact with the end of the rotating frame 741, and the transmission block 75 is embedded and installed in the mounting groove 742. A tooth block 751 is fixed on the outer side of the transmission block 75. The transmission block 75 is meshed with the tooth groove 743 through the tooth block 751, so that when the transmission block 75 rotates, it can drive the rotating frame 741 to rotate synchronously.

[0053] During implementation, when the second synchronous frame 723 needs to be clamped and fixed with the strip plate 61, the second motor 73 can drive the rotating frame 741 to rotate through the transmission block 75, so that the rotating frame 741 as a whole changes from being parallel to the length direction of the protective cover 71 to being parallel to the height direction, so that after the force-bearing frames 727 at both ends are cancelled, the second synchronous frame 723 can move closer along the guide rod 722 through the elastic force of the spring 724, and finally be clamped with the strip plate 61 under the elastic force of the spring 724, so that when the strip plate 61 is subjected to the ditching resistance in the length direction, the resistance can be subjected to the force synchronously through the second synchronous frame 723, so as to reduce the force condition of the electric push rod 1 and improve its service life.

[0054] The control method of the energized parts of the utility model is controlled by manually starting and closing the switch on the trenching equipment. The wiring diagram of the power element and the provision of power supply are common knowledge in the field, and the utility model is mainly used to protect mechanical devices, so the utility model will no longer explain the control method and wiring arrangement in detail.

[0055] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
