Description

Technical Field

[0001] The utility model relates to a supporting device, in particular to a supporting device for an irrigation vehicle carriage, belonging to the technical field of agricultural irrigation vehicles. Background Art

[0002] Existing towed carriages, including other agricultural irrigation vehicles applied by the applicant, usually have a single-axle and double-wheel chassis. The advantage of this chassis is flexible steering and low cost. However, for this form of towed carriage, it needs to rely on the front towing vehicle body to maintain its stability. Once it leaves the front towing vehicle body, it is prone to tilt. Especially when there is liquid loaded inside, the tilt of the towed carriage is likely to cause liquid leakage. In this case, common towed carriages generally support the carriage by arranging lifting columns at the front and rear ends of the carriage. However, the defect of this method is that since the support columns need to directly contact the ground and perform lifting movements, and their lengths are relatively long, when they are not in use for support, they will rise to a relatively high height, resulting in the support columns covering the front and rear ends of the carriage, blocking the entrances and exits of the carriage, and causing inconvenience in use. Therefore, further improvement is needed. Summary of the Utility Model

[0003] The purpose of the utility model is to solve the above-mentioned disadvantages, and provide a supporting device for an irrigation vehicle carriage, which has a simple and reasonable structure, avoids blocking, and improves the convenience of using the carriage.

[0004] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0005] A supporting device for an irrigation vehicle carriage includes a load-bearing bottom plate; a surrounding plate is arranged on the load-bearing bottom plate, and the load-bearing bottom plate has an outer frame body; a plurality of cross beams are arranged inside the outer frame body; a rotary support mechanism is arranged outside the outer frame body; a length adjustment mechanism is arranged outside the rotary support mechanism; a transmission mechanism is arranged inside the load-bearing bottom plate; both ends of the transmission mechanism are connected to the rotary support mechanism; and the transmission mechanism is connected to a driving end.

[0006] Further, there are two rotary support mechanisms, which are symmetrically arranged on both sides of the outer frame body; the rotary support mechanism includes a rotating frame and a support column arranged inside the rotating frame.

[0007] Further, both ends of the rotating frame are open; protrusions are arranged on both sides of the support column; guide grooves are relatively opened in the rotating frame for the protrusions; springs are arranged in the guide grooves; and the springs are connected to the protrusions.

[0008] Further, the length adjustment mechanism is an arc plate; the arc plate is arranged on the outer side of the outer frame; the arc plate is located adjacent to the rotating frame; one side of the support column close to the arc plate is wedge-shaped.

[0009] Further, the distance between the arc plate and the support column gradually decreases from bottom to top; the transmission mechanism includes a main shaft; through holes are formed in the outer frame opposite to the main shaft; the main shaft penetrates through the through holes and is fixedly connected to the rotating frame.

[0010] Further, the transmission mechanism further includes a driven gear main shaft sleeved on the outer side of the main shaft; the driving end is a motor main shaft; the motor is arranged on the side of the cross beam adjacent to the main shaft.

[0011] Further, a driving gear is arranged on the motor; the driving gear meshes with the driven gear.

[0012] The utility model has the following beneficial effects: This design adopts a rotation method to control the lifting of the support column in the rotary support mechanism. The advantage of this method is that when the towed carriage does not need to be supported, the support column is stored flush with the side of the vehicle instead of being in a vertical state, so it will not cause obstruction at the front or rear of the carriage. It will not affect the normal entry and exit of personnel into and out of the carriage. At the same time, by using the combination of rotation and elastic expansion, the area of the entire rotary support mechanism can be small, and it has the ability of automatic operation; and power can be provided for both sides simultaneously through one driving end without the need to set telescopic cylinders on both sides for pushing.

[0018] The terms used herein, including technical and scientific terms, have the same meaning as those commonly understood by those of ordinary skill in the art, unless the term is otherwise defined. It should be understood that the terms defined in the commonly used dictionary have the same meaning as the terms in the prior art.

[0019] See Figures 1 - 3

[0020] An irrigation truck carriage support device includes a load-bearing bottom plate; a surrounding plate 1 is provided on the load-bearing bottom plate, and the load-bearing bottom plate has an outer frame body 2; a plurality of cross beams 3 are arranged inside the outer frame body 2; a rotary support mechanism is arranged outside the outer frame body 2; a length adjustment mechanism is arranged outside the rotary support mechanism; a transmission mechanism is arranged inside the load-bearing bottom plate; both ends of the transmission mechanism are connected to the rotary support mechanism; and the transmission mechanism is connected to the driving end.

[0021] Further, there are two rotary support mechanisms, which are symmetrically arranged on both sides of the outer frame body 2; the rotary support mechanism includes a rotating frame 4 and a support column 5 arranged inside the rotating frame 4.

[0022] Further, both ends of the rotating frame 4 are open; protrusions 5-1 are arranged on both sides of the support column 5; guide grooves are formed in the rotating frame 4 opposite to the protrusions 5-1; springs 6 are arranged in the guide grooves; and the springs 6 are connected to the protrusions 5-1.

[0023] Further, the length adjustment mechanism is an arc plate 7; the arc plate 7 is arranged outside the outer frame body 2; the arc plate 7 is located adjacent to the rotating frame 4; and one side of the support column 5 close to the arc plate 7 is wedge-shaped.

[0024] Further, the distance between the arc plate 7 and the support column 5 gradually decreases from bottom to top; the transmission mechanism includes a main shaft 8; through holes are formed in the outer frame body 2 opposite to the main shaft 8; the main shaft 8 passes through the through holes and is fixedly connected to the rotating frame 4.

[0025] Specifically, as the main shaft 8 drives the rotation of the rotating frame 4, the rotating frame 4 will drive the supporting column 5 inside it to rotate synchronously. Since the distance between the arc plate 7 and the supporting column 5 gradually decreases, during the rotation of the supporting column 5, the upper end of the supporting column 5 will continuously be abutted and pressed by the arc plate 7. Finally, when the supporting column 5 rotates to the vertical position, its bottom can just contact the ground to form a support.

[0026] Furthermore, the transmission mechanism further includes a driven gear 9 sleeved outside the main shaft 8. The driving end is the main shaft of the motor 10. The motor 10 is arranged on the side of the cross beam 3 adjacent to the main shaft 8.

[0027] Furthermore, a driving gear 11 is arranged on the motor 10. The driving gear 11 meshes with the driven gear 9.

[0028] Specifically, when the motor 10 rotates, it will drive the rotation of the driving gear 11, and the rotation of the driving gear 11 will cause the driven gear 9 to be linked with it. As the driven gear 9 rotates, it can drive the rotation of the main shaft 8, and finally cause the rotating frame 4 to rotate, and further cause the supporting column 5 to finally achieve the above-mentioned support.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
