Technical Field

[0001] This utility model relates to the field of belt conveyor technology, specifically, a seedling soil conveyor. Background Technology

[0002] With the advancement of agricultural modernization, traditional manual transportation methods can no longer meet the demands of large-scale agricultural production, especially in the precise distribution and efficient transport of seedling soil. Seedling soil conveyors are widely used in agriculture and nurseries, primarily for distributing seedling soil, fertilizers, and other materials from a central station to various transport devices for subsequent use. They offer advantages such as simple structure, convenient maintenance, and high transport efficiency.

[0003] Current seedling soil conveyors typically receive seedling soil directly from the storage hopper, lift it, and then discharge it into a transport vehicle. Because the seedling soil is not screened, clods and fragments cannot be removed, affecting its subsequent use. Utility Model Content

[0004] The purpose of this utility model is to provide a seedling soil conveyor that solves the problem that existing seedling soil conveyors cannot remove soil clods and fragments from the seedling soil.

[0005] This utility model is achieved through the following technical solution: a seedling soil conveyor, comprising: The belt conveyor is used to transport seedling soil.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example 1:

[0023] This embodiment provides a seedling soil conveyor, specifically as follows: Figures 1-4 As shown, it includes: Belt conveyor 10 is used to transport seedling soil; Inclination adjustment unit 20 is used to adjust the inclination angle of the belt conveyor unit 10; The seedling soil screening section 30 is used to screen out impurities contained in the seedling soil being fed in. The seedling soil screening unit 30 includes a power unit and a screening group driven by it. The screening group includes a screen 301, a screening frame 306, a spill guard 307, and an elastic connector 308. The spill guard 307 is mounted on the belt conveyor unit 10. The screening frame 306 is connected to the spill guard 307 via the elastic connector 308. The screen 301 is mounted on the screening frame 306. The elastic connector 308 can be a spring or a telescopic hinge.

[0024] When transporting seedling soil, the seedling soil is first poured evenly onto the screen 301. The screening frame 306 is then vibrated by the power unit. At this time, the seedling soil will be screened and fall from the screen 301, while soil clods and flakes will remain on the screen 301. The anti-spill cover 307 is used to prevent the seedling soil from falling outside the belt conveyor section 10 during the fall, and it plays a blocking role.

[0025] By setting up a seedling soil screening section 30, the seedling soil can be pre-screened before being transported, effectively removing soil clods and fragments mixed in the seedling soil, ensuring that the transported seedling soil particles are fine and uniform, and improving the subsequent use effect of the seedling soil. Example 2:

[0026] This embodiment further expands the seedling soil screening section 30 based on the above embodiment, specifically as follows: Figure 4 As shown, the power unit includes a screening motor 302, a screening shaft 303, an eccentric wheel 304, and a connecting sleeve 305. The screening motor 302 and the screening shaft 303 are both mounted on the conveying beam frame 101. The screening motor 302 is connected to the screening shaft 303 in a transmission manner. The eccentric wheel 304 is mounted on the screening shaft 303 and is rotatably connected to the screening shaft 303 and hinged to the screening frame 306.

[0027] The screening motor 302 drives the screening shaft 303 to rotate via a chain or belt. The screening shaft 303 drives the eccentric wheel 304 to rotate synchronously. Due to the eccentric setting of the eccentric wheel 304, the connecting sleeve 305 will swing synchronously, thereby causing the screening frame 306 to shake regularly and periodically. Since the connecting sleeve 305 will move laterally and longitudinally, the vibration trajectory of the screening frame 306 also has lateral and longitudinal aspects, thereby improving the screening effect.

[0028] The other parts of this embodiment are the same as those in the above embodiments, and will not be described again. Example 3:

[0029] This embodiment further expands the belt conveyor section 10 based on the above embodiment, specifically as follows: Figures 1-3As shown, the belt conveyor 10 includes a conveyor beam 101, a herringbone belt 103, a drive roller 104, a driven roller 105, and a drive motor 106. The drive roller 104, the driven roller 105, and the drive motor 106 are all mounted on the conveyor beam 101. The drive roller 104 is connected to the drive motor 106 in a transmission manner. The herringbone belt 103 is sleeved on the drive roller 104 and the driven roller 105.

[0030] When the drive motor 106 starts, it drives the active roller 104 through a belt or chain. The active roller 104 drives the herringbone belt 103 to rotate, and the driven roller 105 follows. After the seedling soil is screened by the seedling soil screening section 30, the seedling soil is transported by the herringbone belt 103.

[0031] Furthermore, the belt conveyor 10 also includes a limiting roller 107 and a support roller 109. The support roller 109 is used to support the herringbone belt 103, improve the load-bearing capacity of the herringbone belt 103, and the support roller 109 is arranged in a "V" shape, which allows the seedling soil to gather and accumulate in the middle of the herringbone belt 103, preventing the seedling soil from falling during transportation. The limiting roller 107 is used to limit the herringbone belt 103 and prevent the herringbone belt 103 from falling.

[0032] Furthermore, the belt conveyor 10 also includes a guide hopper 108, which is installed on the conveyor beam 101 and used to adjust the direction of the seedling soil output. After the seedling soil is conveyed from one end of the conveyor beam 101 to the other end, it will continue to be scattered due to inertia. Therefore, the guide hopper 108 is set up so that the seedling soil will be smoothly output along the discharge port of the guide hopper 108 after impacting the guide hopper 108; the guide hopper 108 is used to guide the seedling soil, which is convenient for collection.

[0033] Furthermore, the belt conveyor unit 10 also includes a protective cover 102, which is installed on the conveyor beam 101 to protect the drive motor 106 and the screening motor 302. The protective cover 102 covers the transmission chain or belt and also blocks the sides of the conveyor beam 101, ensuring stable operation of the equipment, preventing seedlings and soil from getting stuck on the chain or belt, and also concealing the conveyor beam 101 to improve the aesthetics of the equipment.

[0034] The other parts of this embodiment are the same as those in the above embodiments, and will not be described again. Example 4:

[0035] This embodiment further expands upon the driven roller 105 based on the above embodiment, specifically as follows: Figure 6As shown, the driven roller 105 includes a support rod 1053, a main shaft 1052, and a diverting roller. The support rod 1053 is mounted on the main shaft 1052, and the diverting roller is mounted on the support rod 1053. The diverting roller includes two symmetrically arranged spiral conveying rods 1051, similar to springs.

[0036] Because the two conveyor rods 1051 rotate in opposite directions, when the driven roller 105 rotates, the contact surface between the conveyor rod 1051 and the herringbone belt 103 will bulge, and the gap between the conveyor rods 1051 cannot support the herringbone belt 103, so it will slightly dent, thus creating orderly uneven grooves. When the conveyor rods 1051 rotate, these uneven grooves will carry a small amount of loose seedling soil and push this seedling soil to both sides of the conveyor beam 101; preventing the seedling soil from accumulating at the end of the conveyor beam 101 and affecting the conveying operation.

[0037] The other parts of this embodiment are the same as those in the above embodiments, and will not be described again. Example

[0038] This embodiment further expands the tilt adjustment unit 20 based on the above embodiment, specifically as follows: Figure 5 As shown, the tilt adjustment unit 20 includes a roller 201, a secondary support 202, an adjusting screw assembly 203, a main support 204, and an adjusting support 205. The secondary support 202 is fixedly connected to the main support 204. The roller 201 is mounted on the main support 204. The adjusting support 205 is slidably connected to the main support 204. One end of the adjusting screw assembly 203 is connected to the main support 204, and the other end is connected to the adjusting support 205.

[0039] Because the equipment (transport vehicles, transport hoppers, etc.) transporting seedlings and soil varies in height, the tilt angle of the belt conveyor 10 is adjusted by the tilt angle adjustment unit 20, thereby adjusting the height of the guide hopper 108. During adjustment, the adjusting screw assembly 203 is manually rotated. At this time, the adjusting bracket 205 extends or retracts on the main bracket 204, and the other end of the conveying beam 101 presses against the ground, working together with the tilt angle adjustment unit 20. The auxiliary bracket 202 forms a triangle with the main bracket 204, improving the support stability of the tilt angle adjustment unit 20.

[0040] The other parts of this embodiment are the same as those in the above embodiments, and will not be described again.

[0041] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications or equivalent changes made to the above embodiments based on the technical essence of the present utility model shall fall within the protection scope of the present utility model.
