Technical Field
[0001] This utility model belongs to the field of cargo loading and unloading technology, and in particular relates to an unloading device for an automatic fertilizer delivery electric vehicle. Background Technology
[0002] Fertilizer is a substance applied to plants or soil to provide essential nutrients, improve soil properties, and enhance soil fertility. The main function of fertilizer is to promote plant growth and development, and increase crop yield and quality.
[0003] In the process of agricultural and forestry fertilization, the demand for fertilizer is large, so three-wheeled electric vehicles are usually used for loading and transferring fertilizer. However, research and investigation have found that currently available electric vehicles often have a small tilt angle when controlling the tilt of the truck bed for unloading, resulting in insufficient unloading of fertilizer from the truck bed. Furthermore, fertilizer tends to adhere to the inside of the truck bed, making manual cleaning difficult and inefficient. Therefore, there is an urgent need to improve the unloading device of existing automatic fertilizer delivery electric vehicles and provide a new automatic fertilizer delivery electric vehicle unloading device. Utility Model Content
[0004] The purpose of this utility model is to address the shortcomings of the existing technology by providing a reasonable design, simple structure, fast unloading speed, and more thorough unloading unloading device for an automatic fertilizer delivery electric vehicle, thereby solving the problems existing in the prior art.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: An unloading device for an automatic fertilizer delivery electric vehicle includes an electric vehicle body. A carriage is rotatably mounted on the upper right side of the electric vehicle body. A crossbar is fixed to the inner side of the right end of the carriage. A partition is provided on the right side of the crossbar. The top of the partition is rotatably connected to the carriage. A handle is installed on the outer wall of the front right end of the carriage. A lifting assembly is provided between the left end of the carriage and the electric vehicle body. A third fixing rod is mounted on the bearing of the bottom surface of the left end of the carriage. A large gear is fixedly sleeved on the outer side of the middle part of the third fixing rod. A striking assembly is provided on the right side of the large gear.
[0006] In a preferred embodiment, one end of the handle is connected to the carriage via a spiral spring, and a limiting block is provided at the bottom of the end of the handle near the carriage, with the limiting block fixedly connected to the carriage.
[0007] In a preferred embodiment, the lifting assembly includes a first fixed rod, a first push rod, a second push rod, a second fixed rod, and a base. The first fixed rod is fixedly installed on the inner side of the left end of the electric vehicle body. The outer sides of both the front and rear ends of the first fixed rod are bearing sleeved with first push rods. The ends of the two first push rods away from the first fixed rod are hinged with second push rods. The other ends of the second push rods are fixedly sleeved on the outer side of the third fixed rod. A second fixed rod is fixed between the two second push rods. The outer sides of the middle of both the first fixed rod and the second fixed rod are bearing sleeved with bases.
[0008] In a preferred embodiment, a multi-section electric push rod is fixedly installed between the two bases, wherein the first push rod and the second push rod are of equal length.
[0009] In a preferred embodiment, the striking assembly includes a horizontal shaft, a pinion, rubber rods, and steel balls. The horizontal shaft bearing is installed at the bottom left end of the carriage. A pinion is fixedly sleeved on the outer side of the middle part of the horizontal shaft. A set of rubber rods is glued to the outer side of both the front and rear ends of the horizontal shaft. Each set of rubber rods consists of three rods arranged in a ring around the horizontal shaft. A steel ball is fixedly connected to the end of the rubber rod away from the horizontal shaft.
[0010] In a preferred embodiment, the pinion and the large gear are meshed together, and the diameter of the pinion is only one-third of the diameter of the large gear. The length of the rubber rod is greater than the shortest distance between the horizontal shaft and the carriage.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: In the solution of this utility model: The handle utilizes a spiral spring to maintain its stability, and the handle, in conjunction with the crossbar, can limit the vertical position of the partition, facilitating the stable sealing of the right-end discharge port of the truck bed and making fertilizer transfer easier. During unloading, manually pulling the handle to rotate it to a vertical position releases the partition's positioning. When the truck bed is tilted, the partition remains vertical due to gravity, allowing the right-end discharge port of the truck bed to open for easy unloading. Activating the multi-section electric push rod can push the second fixed rod and control the rotation of the first and second push rods, making it easier to push the carriage upwards. Compared with the existing technology where the electric push rod is directly connected to the carriage, this device can push the carriage to a larger tilt angle, facilitating unloading. Moreover, when the second push rod drives the third fixed rod and the large gear to rotate, it can control the small gear meshing with the large gear to rotate rapidly. This allows the rubber rods and steel balls at both ends of the horizontal shaft to repeatedly tap the bottom of the carriage, making it easier to shake off the fertilizer adhering to the inner wall of the carriage. This results in more complete unloading, higher efficiency, and less effort. Attached Figure Description

[0014] The embodiments described below are merely some embodiments of the present invention and do not represent all embodiments consistent with the present invention. Exemplary embodiments will now be described with reference to the accompanying drawings: like Figure 1-5 As shown, the unloading device of the automatic fertilizer delivery electric vehicle of this utility model includes an electric vehicle body 1, a carriage 2 rotatably mounted on the upper right side of the electric vehicle body 1, a crossbar 3 fixed on the inner side of the right end of the carriage 2, a partition 4 provided on the right side of the crossbar 3, the top of the partition 4 rotatably connected to the carriage 2, a handle 5 installed on the outer wall of the front right end of the carriage 2, a lifting component 8 provided between the left end of the carriage 2 and the electric vehicle body 1, a third fixing rod 10 mounted on the bearing of the bottom surface of the left end of the carriage 2, a large gear 11 fixedly sleeved on the outer side of the middle part of the third fixing rod 10, and a striking component 9 provided on the right side of the large gear 11.
[0015] Based on the above structure, one end of the handle 5 is connected to the carriage 2 via a spiral spring 6, and a limiting block 7 is provided at the bottom of the end of the handle 5 near the carriage 2, and the limiting block 7 is fixedly connected to the carriage 2.
[0016] In this embodiment, the handle 5 is kept stable by the spiral spring 6, and the rotation range of the handle 5 is limited by the limiting block 7.
[0017] Based on the above structure, the lifting assembly 8 includes a first fixed rod 81, a first push rod 82, a second push rod 83, a second fixed rod 84, and a base 85. The first fixed rod 81 is fixedly installed on the inner side of the left end of the electric vehicle body 1. The first push rod 82 is bearing sleeved on the outer side of both the front and rear ends of the first fixed rod 81. The second push rod 83 is hinged to the end of each of the two first push rods 82 away from the first fixed rod 81. The other end of the second push rod 83 is fixedly sleeved on the outer side of the third fixed rod 10. The second fixed rod 84 is fixed between the two second push rods 83. The base 85 is bearing sleeved on the outer side of the middle part of both the first fixed rod 81 and the second fixed rod 84.
[0018] Based on the above structure, a multi-section electric push rod 86 is fixedly installed between the two bases 85, and the first push rod 82 and the second push rod 83 are of equal length.
[0019] In this embodiment, activating the multi-section electric push rod 86 can push the second fixed rod 84 and control the rotation of the first push rod 82 and the second push rod 83, which facilitates pushing the carriage 2 to a larger tilt angle and facilitates unloading.
[0020] Based on the above structure, the striking component 9 includes a horizontal shaft 91, a pinion 92, a rubber rod 93, and a steel ball 94. The horizontal shaft 91 is bearing-mounted at the bottom left end of the carriage 2. The pinion 92 is fixedly sleeved on the outer side of the middle part of the horizontal shaft 91. A set of rubber rods 93 is glued to the outer side of both the front and rear ends of the horizontal shaft 91. Each set of rubber rods 93 consists of three in a ring around the horizontal shaft 91. A steel ball 94 is fixedly connected to the end of the rubber rod 93 away from the horizontal shaft 91.
[0021] Based on the above structure, the pinion 92 and the large gear 11 are meshed and connected, and the diameter of the pinion 92 is only one-third of the diameter of the large gear 11. The length of the rubber rod 93 is greater than the shortest distance between the horizontal shaft 91 and the carriage 2.
[0022] In this embodiment, when the carriage 2 rotates, the striking component 9 can be controlled to rotate. The rubber rods 93 and steel balls 94 at both ends of the horizontal shaft 91 can strike the bottom of the carriage 2 multiple times, which makes it easier to shake off the fertilizer adhering to the inner wall of the carriage 2 and unload it more fully.
[0023] The working principle of this utility model is as follows: In use, fertilizer is first added into the carriage 2, and the electric vehicle body 1 is used to transport the fertilizer to the designated agricultural and forestry fertilization location. Then, the multi-section electric push rod 86 can be activated to push the second fixed rod 84 and control the rotation of the first push rod 82 and the second push rod 83, which makes it easy to push the carriage 2 upward. Moreover, compared with the existing technology where the electric push rod is directly connected to the carriage 2, this device can push the carriage 2 to rotate at a larger angle, which is convenient for unloading. Before the control carriage 2 starts rotating, the handle 5 can be manually pulled to a vertical position. At this time, the restriction on the partition 4 can be released. When the carriage 2 rotates and tilts, the partition 4 can remain vertical due to gravity. Figure 4 As shown, this facilitates the opening of the discharge port on the right end of the carriage 2 for easy unloading. Moreover, when the second push rod 83 drives the third fixed rod 10 and the large gear 11 to rotate, it can control the small gear 92 meshing with the large gear 11 to rotate rapidly, which can make the rubber rods 93 and steel balls 94 at both ends of the horizontal shaft 91 rotate, which can knock the bottom of the carriage 2 multiple times, making it easier to shake off the fertilizer adhering to the inner wall of the carriage 2, resulting in more complete unloading, higher efficiency, and less effort.
[0024] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Any equivalent changes, modifications, substitutions, and variations made by those skilled in the art based on the concept of this utility model and on the basis of existing technology through logical analysis, reasoning, or limited experiments shall be within the scope of protection defined by the claims.
