DETAILED DESCRIPTION

[0022] The utility model is further described in detail below through the drawings and embodiments.

[0023] Embodiment 1: Figure 1-4 As shown: a front and rear support mechanism for a garden excavation crane, including a body 1 and a body 2 fixedly mounted at one end of the body 1, which is a prior art. A front support mechanism 3 is provided at the bottom of the body 2. The front support mechanism 3 is composed of a roller 32 and an extension assembly. The extension assembly is connected to the bottom of the body 2. The lower end of the extension assembly is pivotally connected to the roller 32, and the roller 32 can contact the ground after the extension assembly is extended. A rear support mechanism 5 is provided at the bottom of the end of the body 1 away from the body 2, and a connecting block 4 is welded to the bottom of the body 1, and a connecting portion is provided between the connecting block 4 and the rear support mechanism 5. One end of the connecting portion is pivotally connected to the connecting block 4. The other end of the connecting portion is connected to the rear support mechanism 5. During operation, when the center of gravity tilts forward, the front support mechanism 3 is extended to press the roller 32 against the ground. Prevent the locomotive from tilting forward. When the center of gravity tilts backward, the rear support mechanism 3 is against the ground to prevent the locomotive from tilting backward. And when the front support mechanism 3 is extended, the roller 32 contacts the ground. The roller 32 can have the effect of flattening the soil.

[0024] The extension assembly includes a front cross beam 31, a push rod 1 33 and two telescopic rods 34. The front cross beam 31 is pivotally connected to the roller 32, and the front cross beam 31 is welded to the two telescopic rods 34. The upper end of the telescopic rod 34 is tilted and welded to the bottom of the vehicle body 2. The push rod 1 33 is located between the two telescopic rods 34. The middle part of the front cross beam 31 is welded to the push rod 1 33. The push rod 1 33 is welded to the bottom of the vehicle body 2. When working, the push rod 1 33 extends to drive the telescopic rod 34 to extend. The roller 32 of the front cross beam 31 contacts the ground. When the telescopic rod 34 is extended, the front cross beam 31 and the roller 32 cooperate.

[0025] The front support mechanism 3 facilitates the front end of the vehicle head 2 to cross the ditch. When there is a ditch on the ground ahead, the push rod 1 33 drives the telescopic rod 34 to extend, so that the roller 32 crosses the ditch and contacts the ground ahead. Since the roller can rotate, the vehicle can smoothly cross the ditch with the roller 33 as the support point during the vehicle's movement.

[0026] The rear support mechanism 5 includes a rear cross beam 51, a push rod 52, a stop block 53, a pressure roller 54 and a scraper 55. The rear cross beam 51 is pivotally connected to the scraper 55. The pressure roller 54 is located between the rear cross beam 51 and the scraper 55, and the end of the pressure roller 54 is pivotally connected to the rear cross beam 51. The lower end of the push rod 52 is pivotally connected to the rear cross beam 51, and the upper ends of the push rod 52 are pivotally connected to the stop block 53. The top of the stop block 53 is welded to the bottom of the vehicle body. The rear cross beam 51 is connected to the connecting block 4 through a connecting portion.

[0027] The connecting part is a connecting rod 6, one end of which is pivotally connected to the connecting block 4, and the other end of which is welded to the rear cross beam 51. During operation, since the connecting rod 6 and the push rod 2 52 have different inclinations, when the push rod 2 52 is extended, the connecting rod 6 will tend to rotate downward. The connecting rod rotates downward to make the pressure roller 54 contact the ground. Therefore, when the center of gravity moves backward, the rear end of the vehicle will sink, causing the rear end of the vehicle to contact the ground and the vehicle cannot move forward. At this time, the push rod 2 52 is used to make the pressure roller 54 contact the ground. The connecting rod 6, the pressure roller 54 and the rear cross beam 51 cooperate to play a supporting role. At the same time, the pressure roller 54 can be used as a tire.

[0028] When the push rod 2 52 is extended, the pressing roller 54 contacts the ground. When the vehicle moves backward, the shovel blade 55 abuts against the axial end of the pressing roller 54. The shovel blade 55 can shovel away the soil pile. It is convenient to clean up the soil pile shoveled up during planting.

[0029] Combined with Figure 4 The upper end of the scraper 55 is pivotally connected to the rear cross beam, so the scraper 55 does not hinder the rotation of the pressure roller 55.

[0030] Compared with the prior art, the front and rear support mechanism for the garden excavator crane cooperates with the push rod 1 33 and the roller 32 to make the roller 32 against the ground to prevent the vehicle from tilting forward. Then, the push rod 2 52, the connecting rod 6 and the pressure roller 54 cooperate to make the connecting rod 6 and the pressure roller 54 against the rear end of the vehicle, thereby preventing the vehicle from tilting backward. The supporting effect is achieved. With the cooperation of the roller 32 and the telescopic rod 34, it is convenient for the vehicle to cross the earth ditch at the front end. The shovel blade 55 can be used to push away the soil pile when the vehicle moves backward. The effect of facilitating the cleaning of the soil pile generated after excavation is achieved. Multifunctionality is achieved, and the overall application range of the excavator crane is improved.

[0031] Embodiment 2: Figure 5 As shown: the basic structure of this embodiment is roughly the same as that of the first embodiment, and the following are the differences: the connecting part is a main rod 7 and a secondary rod 71, the main rod 7 is pivotally connected to the connecting block 4, and the main rod 7 is slidably matched with the secondary rod 71 at one end facing the rear cross beam 51, and the secondary rod 71 can extend into the main rod 7. The secondary rod 71 is connected to the rear cross beam 51.

[0032] At this time, with the help of the power of the push rod 2, the auxiliary rod 71 is extended from the main rod 7. The rear cross beam 51 can be extended outward, so that the blade 55 can push the soil pile away when the station is stationary. And the overall supporting effect of the rear support mechanism 5 can be better improved.

[0033] The above push rod 1 33 and push rod 2 52 are both hydraulic push rods, which are conventional technical means. They are not the innovation of this solution, and no innovation has been made to them, so the specific model, specific structure, driving mode, etc. are all conventional technical means and will not be described in detail.

[0034] Working principle: When in use, when the center of gravity tilts forward, the push rod 1 33 extends to drive the telescopic rod 34 to extend. The roller 32 of the front cross beam 31 contacts the ground. The front cross beam 31 and the push rod 1 33 support the front end of the vehicle to prevent the vehicle from tilting forward. When the center of gravity tilts backward, the push rod 2 52 extends to drive the connecting rod 6 to rotate downward, so that the pressure roller 54 contacts the ground to prevent the vehicle body from tilting backward.

[0035] In summary, the front and rear support mechanism for the garden excavator crane, through the push rod 1 33 and the roller 32, makes the roller 32 against the ground to prevent the vehicle from tilting forward. Then, the push rod 2 52, the connecting rod 6 and the pressure roller 54 are used to make the connecting rod 6 and the pressure roller 54 against the rear end of the vehicle, thereby preventing the vehicle from tilting backward. The support effect is achieved. With the help of the roller 32 and the telescopic rod 34, it is convenient for the vehicle to cross the ditch at the front. The blade 55 is used to push the soil pile away when the vehicle moves backward. The effect of facilitating the cleaning of the soil pile generated after excavation is achieved. Multifunctionality is achieved, and the overall application range of the excavator crane is improved.
