Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery, in particular to a platform for agricultural machinery. Background Art

[0002] Agricultural machinery refers to various machines used in the production process of crop planting and animal husbandry, as well as in the primary processing and treatment of agricultural and animal products. Agricultural machinery includes agricultural power machinery, farmland construction machinery, soil tillage machinery, planting and fertilization machinery, plant protection machinery, farmland irrigation and drainage machinery, crop harvesting machinery, agricultural product processing machinery, animal husbandry machinery and agricultural transportation machinery, etc. Some agricultural picking machinery needs to be operated at high altitudes, so lifting platforms are needed to send agricultural machinery to high places.

[0003] Publication number "CN220449744U" provides a lifting platform for agricultural machinery, including a base, which is the main body of the lifting platform for agricultural machinery; a multi-stage hydraulic cylinder, which is installed on the top of the base; a receiving groove, which is opened on both sides of the base; a fixing structure, which is arranged inside the receiving groove; the fixing structure includes a rotating ball, a rotating rod, a threaded sleeve and a screw. This device overcomes the shortcomings of the prior art. Through springs, card frames and guide rods, personnel open the box door to enter the lifting box, but when the personnel do not lock it or close it tightly, the personnel may break through the box door and accidentally fall out of the lifting platform during the operation, causing physical injury or even life-threatening. Through screws, threaded sleeves and rotating rods, the stability of the entire lifting platform in use is increased, and the threat to personnel safety is reduced. Through the card balls and card slots, it is convenient to clean the anti-slip strips on the anti-slip plate after it is filled with mud and dried.

[0004] However, the above device still has the following problems during implementation:

[0005] In order to facilitate the movement of the mechanical platform, universal wheels are generally installed at the bottom of the platform. However, considering that the ground location of the platform is different and some ground has potholes, it is difficult to ensure the stability of the platform only by relying on the self-locking contact of the universal wheels with the ground, which poses a safety hazard and is not conducive to user use.

[0034] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0035] See also Figure 1-Figure 6 , the utility model provides a technical solution:

[0036] Embodiment 1:

[0037] A platform for agricultural machinery includes a base 1, a lifting box 2 and two hydraulic rods 3. The hydraulic rods 3 are fixedly installed on the top of the base 1. The output ends of the hydraulic rods 3 are fixedly connected to the bottom of the lifting box 2. Four universal wheels 4 are fixedly installed on the bottom of the base 1 by screws. Four receiving grooves 5 are opened at the bottom of the base 1. A supporting mechanism is arranged inside the receiving grooves 5 to support the platform.

[0038] The adjustment mechanism is fixedly arranged on the base 1 and can adjust the position supported by the support mechanism.

[0039] One implementation of the first embodiment is as follows: the support mechanism comprises a support plate 6 movably arranged inside the receiving groove 5, a threaded rod 7 is threadedly connected to the top of the support plate 6, a rotating block 8 is fixedly connected to the bottom of the threaded rod 7, and a moving block 9 is fixedly connected to the bottom of the threaded rod 7;

[0040] A threaded hole 10 for use with the threaded rod 7 is provided on the top of the support plate 6 .

[0041] In this embodiment, it is considered that due to the different ground positions where the platform is used, some grounds may have potholes. It is difficult to ensure the stability of the platform only by the self-locking contact of the universal wheel 4 with the ground, which poses a safety hazard. Therefore, by setting a support mechanism, after the platform is moved to the specified position through the universal wheel 4, the handle 20 is rotated to drive the rotating block 8 and the threaded rod 7 to rotate. The threaded rod 7 rotates in the threaded hole 10 and gradually moves downward, while driving the abutting block 9 and the buffer block 22 downward until the buffer block 22 contacts the ground. At this time, the platform as a whole can be supported, thereby improving the stability of the platform when lifting agricultural machinery;

[0042] The invention solves the problem that, due to the different ground positions where the platform is used, some grounds may have potholes, and it is difficult to ensure the stability of the platform only by the self-locking contact of the universal wheel 4 with the ground, which may cause potential safety hazards.

[0043] Preferably, T-shaped blocks 18 are fixedly connected to both sides of the support plate 6 , and the inner wall of the accommodating groove 5 is provided with a T-shaped groove 19 used in conjunction with the T-shaped block 18 .

[0044] In this embodiment, by providing the T-shaped block 18 and the T-shaped slot 19, the moving track of the support plate 6 can be limited so that the support plate 6 can only move along the track of the T-shaped block 18 and the T-shaped slot 19, while improving the stability during movement.

[0045] Preferably, handles 20 are fixedly connected to both sides of the rotating block 8 , and anti-slip rings 21 are fixedly connected to the surfaces of the handles 20 .

[0046] In this embodiment, the handle 20 and the anti-slip ring 21 are provided to provide a leverage point for the user to twist the rotating block 8 and the threaded rod 7 so that the user can hold them with his palms. At the same time, the anti-slip ring 21 can also improve the anti-slip effect of the handle 20.

[0047] Preferably, a buffer block 22 is fixedly connected to the bottom of the abutting block 9, and the buffer block 22 is made of rubber.

[0048] In this embodiment, the buffer block 22 is provided to play a buffering role when the abutting block 9 contacts the ground. Meanwhile, the buffer block 22 itself is made of rubber and has a rebound property, and can also contact the ground more firmly.

[0049] Embodiment 2:

[0050] On the basis of the first embodiment, the support mechanism in this embodiment can play a supporting role for the platform, but considering the factors of the ground environment, if the position of the support mechanism cannot be adjusted, the support position is in a pit, which will also affect the stability of the platform. The adjustment mechanism in this application includes a shell 11 movably arranged on the top of the support plate 6, one side of the shell 11 is fixedly connected to one side of the base 1, and a moving block 12 is arranged inside the shell 11. Two positioning rods 13 are fixedly connected to the bottom of the moving block 12. The bottom of the positioning rod 13 penetrates to the bottom of the shell 11, and a plurality of positioning holes 14 used in conjunction with the positioning rod 13 are opened on the top of the support plate 6;

[0051] A push rod 15 is fixedly connected to one side of the moving block 12 , and a push groove 16 for use with the push rod 15 is formed on one side of the housing 11 .

[0052] In this embodiment, the ground environment is taken into consideration. If the position of the support mechanism cannot be adjusted and the support position is in a pothole, the stability of the platform will be affected. Therefore, by setting an adjustment mechanism, the push rod 15 can be moved upward, and the push rod 15 drives the moving block 12 and the positioning rod 13 to move upward and leave the inside of the positioning hole 14. At this time, the support plate 6 is not restricted, and the support plate 6 can be pulled to move along the trajectory of the T-shaped block 18 and the T-shaped slot 19, so that the support plate 6 leaves the accommodating slot 5. Figure 2 As shown, the push rod 15 is then released, and the elastic force generated by the spring 17 pushes the moving block 12 and the positioning rod 13 downward, so that the positioning rod 13 enters the corresponding positioning hole 14, and the support position of the support mechanism can be adjusted, thereby effectively improving the stability of the platform;

[0053] The problem that the stability of the platform will be affected if the position of the support mechanism cannot be adjusted and the support position is in a pothole is solved by taking the ground environment into consideration.

[0054] Preferably, a spring 17 is fixedly connected to the top of the moving block 12 , and the top of the spring 17 is fixedly connected to the inner wall of the housing 11 .

[0055] In this embodiment, the spring 17 is provided to generate elastic force to push the moving block 12 and the positioning rod 13 downward, so that the positioning rod 13 enters the corresponding positioning hole 14, thereby achieving a reset effect.

[0056] Working principle: By moving the push rod 15 upward, the push rod 15 drives the moving block 12 and the positioning rod 13 to move upward and leave the interior of the positioning hole 14. At this time, the support plate 6 is no longer restricted, and the support plate 6 can be pulled to move along the track of the T-shaped block 18 and the T-shaped slot 19, so that the support plate 6 leaves the receiving slot 5. Figure 2As shown, the push rod 15 is then released, and the spring 17 generates an elastic force to push the moving block 12 and the positioning rod 13 downward, so that the positioning rod 13 enters the corresponding positioning hole 14, and the support position of the support mechanism can be adjusted;

[0057] Then, by rotating the handle 20, the rotating block 8 and the threaded rod 7 are driven to rotate. The threaded rod 7 rotates in the threaded hole 10 and will gradually move downward, while driving the abutment block 9 and the buffer block 22 downward until the buffer block 22 contacts the ground. At this time, the platform as a whole can be supported, thereby improving the stability of the platform when lifting agricultural machinery.

[0058] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
