[0022] Please refer to Figure 1-6 , the present utility model provides a free wheeled transport vehicle, including a base 1 of the wheeled transport vehicle. A compartment 2 is rotatably connected to the top of the base 1 of the wheeled transport vehicle. A pushing plate 3 is arranged on one side of the inner cavity of the compartment 2. A sealing door panel 4 is attached to one side of the surface of the compartment 2. A connecting seat 5 is fixed to the side of the pushing plate 3 and the sealing door panel 4 that are close to each other. A first motor 6 is fixed to the inner surface of one of the connecting seats 5. The output end of the first motor 6 is fixed with a threaded cylinder 7. A first threaded rod 8 is threadedly connected to the middle position of the threaded cylinder 7. One side of the first threaded rod 8 is fixed to the surface of the other connecting seat 5. Limiting shafts 9 are slidably inserted into the surfaces at both ends of the other connecting seat 5. One side of the limiting shaft 9 is fixed to the surface of one of the connecting seats 5. A rack 12 is fixed to the position at one end of the top surface of the compartment 2 and at the bottom of the pushing plate 3. A second motor 10 is fixed to the surface of one end of the pushing plate 3. The output end of the second motor 10 passes through the pushing plate 3 and is rotatably connected to the inner surface of the pushing plate 3. A circular gear 11 is fixedly sleeved on the outer peripheral surface of the output end of the second motor 10. The circular gear 11 is meshed with the rack 12. A slot 15 is opened on the surface of the compartment 2 close to the sealing door panel 4. A sealing strip 16 is inserted into the slot 15. One side of the sealing strip 16 passes through the adjacent slot 15 and is fixed to the surface of the sealing door panel 4. By starting the second motor 10, the pushing plate 3 can move horizontally and cancel the working effect of the pushing plate 3 sealing one side of the compartment 2, so that the pushing plate 3 can push the goods placed in the compartment 2 out of the interior of the compartment 2. By starting the first motor 6, the distance between the pushing plate 3 and the sealing door panel 4 can be reduced to prevent the sealing door panel 4 from touching the ground when the compartment 2 tilts, which is beneficial to ensuring the normal operation of the unloading operation of the goods. By inserting the sealing strip 16 into the slot 15, the sealing effect between the sealing door panel 4 and the compartment 2 can be improved.
[0023] Furthermore, as Figure 1 and Figure 4As shown, it is worth specifically explaining that a positioning shaft 13 is inserted through the top position of one side surface of the carriage 2, and both sides of the positioning shaft 13 are fixed to the other end of the top surface of the carriage 2. Since the positioning shaft 13 can limit the movement trajectory of the push plate 3, the push plate 3 can move more smoothly in the horizontal direction.
[0024] Furthermore, as shown in Figure 1 , Figure 5 and Figure 6 As shown, it is worth specifically explaining that rod grooves 19 are opened at both ends of the top surface of the base 1 of the wheeled transport vehicle. A second threaded rod 20 is rotatably connected inside the rod grooves 19. One side of the outer peripheral surface of the second threaded rod 20 is threadedly connected with a threaded sleeve 21. The top of the threaded sleeve 21 is hinged with a support rod 18, and the top of the support rod 18 is hinged with the bottom surface of the carriage 2. Since the inner cavity of the rod groove 19 can resist and limit the threaded sleeve 21, the threaded sleeve 21 can move in the horizontal direction under the cooperation between the internal thread structure of the inner wall of the threaded sleeve 21 and the external thread structure of the outer peripheral surface of the second threaded rod 20, so that the support rod 18 can change its angle, so that the carriage 2 can change its angle, thus facilitating the unloading operation of the goods in the inner cavity of the carriage 2.
[0025] Furthermore, as shown in Figure 3 As shown, it is worth specifically explaining that a third motor 17 is fixed on one side surface of the base 1 of the wheeled transport vehicle. One side of one of the second threaded rods 20 passes through the base 1 of the wheeled transport vehicle and is fixed to the output end of the third motor 17. A receiving shaft 23 is rotatably connected at the middle position between the two rod grooves 19. A first bevel gear 22 is fixedly sleeved on the other side of the outer peripheral surface of the second threaded rod 20. A second bevel gear 24 is fixedly sleeved on the outer peripheral surface of the receiving shaft 23 near the first bevel gear 22. The first bevel gear 22 and the second bevel gear 24 at the adjacent position are meshed with each other. When the third motor 17 is started, one of the second threaded rods 20 can rotate, so that one of the first bevel gears 22 can rotate along with the second threaded rod 20. Thus, the receiving shaft 23 can rotate under the meshing action between the first bevel gear 22 and the second bevel gear 24, and the two second threaded rods 20 can rotate synchronously under the meshing action between the other first bevel gear 22 and the second bevel gear 24.
[0026] This solution has the following working process: During actual use, when the user needs to unload the goods placed in the inner cavity of the carriage 2, the user first turns on the third motor 17 so that one of the second threaded rods 20 can rotate, and then one of the first bevel gears 22 can rotate along with the second threaded rod 20. Thus, under the meshing action between the first bevel gear 22 and the second bevel gear 24, the receiving shaft 23 can rotate, and then under the meshing action between another first bevel gear 22 and the second bevel gear 24, the two second threaded rods 20 can rotate synchronously. Since the inner cavity of the rod groove 19 can restrict the movement of the threaded sleeve 21, under the cooperation between the internal thread structure on the inner wall of the threaded sleeve 21 and the external thread structure on the outer peripheral surface of the second threaded rod 20, the threaded sleeve 21 can move horizontally, causing the support rod 18 to change its angle, and then causing the carriage 2 to change its angle, which facilitates the unloading operation of the goods in the inner cavity of the carriage 2. Subsequently, the user turns on the second motor 10 so that the circular gear 11 can rotate, and then the circular gear 11 can mesh with the rack 12 and cooperate with the positioning shaft 13 to limit the movement of the push plate 3, enabling the push plate 3 to move horizontally and drive the sealing door plate 4 to move horizontally. As a result, the sealing door plate 4 that seals one side of the inner cavity of the carriage 2 is separated from the carriage 2. When the push plate 3 pushes the goods placed in the inner cavity of the carriage 2 and the distance between the sealing door plate 4 and the carriage 2 becomes too large, the first motor 6 is started so that the threaded barrel 7 can rotate. Thus, under the cooperation of the threaded structures of the threaded barrel 7 and the first threaded rod 8 and the limiting effect of the limiting shaft 9 on the connecting seat 5, the distance between the two connecting seats 5 is reduced to prevent the sealing door plate 4 from colliding with the ground. After the push plate 3 pushes the goods in the inner cavity of the carriage 2 out of the inner cavity of the carriage 2, the unloading operation of the goods on the base 1 of the wheeled transport vehicle can be completed.
[0027] According to the above working process, it can be known that by starting the second motor 10, the push plate 3 can move horizontally and cancel the working effect of the push plate 3 sealing one side of the carriage 2, so that the push plate 3 can push the goods placed in the carriage 2 out of the interior of the carriage 2. And by starting the first motor 6, the distance between the push plate 3 and the sealing door panel 4 can be reduced to prevent the sealing door panel 4 from touching the ground when the carriage 2 tilts, which is beneficial to ensuring the normal operation of the unloading operation of the goods, thus improving the practicability of the device. By starting the third motor 17 and under the connection action of the receiving shaft 23, the two second threaded rods 20 can rotate synchronously, so that the threaded sleeve 21 can move horizontally, so that the support rod 18 can change its angle, so that the carriage 2 can change its angle, so that the goods inside the inner cavity of the carriage 2 can be separated from the interior of the carriage 2 under the action of gravity, which is convenient for further improving the convenience during unloading, and thus further improves the practicability of the device.
[0028] Furthermore, as Figure 4 shown, it is worth specifically explaining that on both sides of the outer peripheral surface of the positioning shaft 13, springs 14 are sleeved. One side of the two springs 14 away from each other is fixed to the other end of the top surface of the carriage 2. Due to the setting of the springs 14, it can play a buffering role when the push plate 3 moves to both sides of the outer peripheral surface of the positioning shaft 13 to avoid direct collision with the top surface of the carriage 2, thus further improving the smoothness of the movement of the push plate 3.
[0029] In summary: By starting the second motor 10, the push plate 3 can move horizontally and cancel the working effect of the push plate 3 sealing one side of the carriage 2, so that the push plate 3 can push the goods placed in the carriage 2 out of the interior of the carriage 2. And by starting the first motor 6, the distance between the push plate 3 and the sealing door panel 4 can be reduced to prevent the sealing door panel 4 from touching the ground when the carriage 2 tilts, which is beneficial to ensuring the normal operation of the unloading operation of the goods, thus improving the practicability of the device. By starting the third motor 17 and under the connection action of the receiving shaft 23, the two second threaded rods 20 can rotate synchronously, so that the threaded sleeve 21 can move horizontally, so that the support rod 18 can change its angle, so that the carriage 2 can change its angle, so that the goods inside the inner cavity of the carriage 2 can be separated from the interior of the carriage 2 under the action of gravity, which is convenient for further improving the convenience during unloading, and thus further improves the practicability of the device. Due to the setting of the springs 14, it can play a buffering role when the push plate 3 moves to both sides of the outer peripheral surface of the positioning shaft 13 to avoid direct collision with the top surface of the carriage 2, thus further improving the smoothness of the movement of the push plate 3.
[0030] The first motor 6, the second motor 10, and the third motor 17 can be purchased from the market. The first motor 6, the second motor 10, and the third motor 17 are equipped with power supplies, which are mature technologies in this field and have been fully disclosed. Therefore, they will not be repeated in the specification.
