Pepper seed seedling tray multi-hole synchronous seeding device

Abstract

This utility model belongs to the field of chili pepper planting technology and discloses a multi-hole synchronous sowing device for chili pepper seedling trays. It includes a seed adding body, on which a transmission component and a displacement component are respectively installed. A seed adding station is connected to the surface of the seed adding body. This utility model uses a main bevel gear and a secondary bevel gear to facilitate synchronous rotation of the two transmission gears. Both the transmission gears and the toothed rack have a fixed number of teeth, thus the meshing transmission between them has a fixed transmission ratio, facilitating the displacement of the toothed rack and the seedling tray by a specified distance. By setting the transmission gear to mesh with the leftmost tooth of the toothed rack, it ensures that the seedling tray is accurately positioned directly below the seed adding station each time, avoiding misalignment of chili pepper seeds due to displacement deviation. This is particularly suitable for the needs of chili peppers with small seeds requiring precise placement in the holes.

Description

Technical Field

[0001] This utility model belongs to the field of chili planting technology, specifically a multi-hole synchronous sowing device for chili seedling trays. Background Technology

[0002] In the chili pepper cultivation industry, seedling raising is a key link to ensure subsequent growth and yield, and seedling trays are the core supporting tools for this link. Chili pepper seedling trays usually adopt a structure with regularly arranged holes. Each hole can be filled with seedling substrate, providing an independent space for the germination and seedling growth of single or multiple chili pepper seeds, which facilitates centralized management and subsequent transplanting operations.

[0003] However, the following problems were found in the implementation of the relevant technologies: Traditional sowing devices mostly use belt drive or manual plate pushing. The belt is prone to slippage due to wear and insufficient tension. Manual plate pushing relies on experience to judge the position, which will cause the sowing plate to be unable to accurately align with the seed adding position. Chili seeds are small, and once the sowing plate is misaligned, the seeds are prone to leaking out of the plate or not falling into the preset holes. Subsequent manual re-sowing is required, which increases the workload and affects the uniformity of seedlings. Utility Model Content

[0004] To address the problems mentioned in the background art, this utility model provides a multi-hole synchronous sowing device for chili seedling trays, which has the advantage of accurately positioning the seedling trays and the sowing positions.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-hole synchronous sowing device for chili seedling trays, comprising a seed adding body, wherein a transmission component and a displacement component are respectively provided on the seed adding body, a seed adding station is connected to the surface of the seed adding body, a shell is connected to the surface of the seed adding body, a drive source is connected to the inner side of the top of the shell, the drive source has two power output ends, a seedling tray is placed inside the shell, connecting blocks are connected to both sides of the seedling tray, bolts are threaded to the inner sides of the two connecting blocks, and a sealing door is snapped onto one side of the shell;

[0006] The surface of the transmission component is electrically connected to the two power output ends of the drive source to drive the transmission component to rotate.

[0007] The surface of the displacement component is poweredly connected to the power output end of the transmission component to drive the seedling tray to make a quantitative displacement in the horizontal direction.

[0008] Preferably, the transmission assembly includes two connecting rods and two secondary bevel gears. The two connecting rods are respectively disposed on the power output ends at both ends of the drive source. One end of each of the two connecting rods is connected to a main bevel gear. The two secondary bevel gears are respectively meshed with the two main bevel gears. The bottom end of each of the two secondary bevel gears is connected to a fixing rod.

[0009] Preferably, the two auxiliary bevel gears are symmetrically arranged on the front and rear sides of the vertical center line of the housing.

[0010] Preferably, the displacement assembly includes two transmission gears, two rack plates, and two limiting grooves. The two transmission gears are respectively disposed at the bottom ends of the two fixed rods, the two rack plates are respectively meshed with the two transmission gears, the bottom ends of the two rack plates are connected to limiting blocks, and the two limiting grooves are respectively opened on the inner side of the bottom end of the housing.

[0011] Preferably, the bottom ends of both transmission gears are rotatably connected to the inner side of the bottom end of the housing via bearings.

[0012] Preferably, the inner sides of the two rack plates are threadedly connected to the surfaces of the two bolts, respectively.

[0013] Preferably, the longitudinal sections of the two limiting blocks and the two limiting grooves are both inverted "T" shapes, and the surfaces of the two limiting blocks are respectively engaged with the sliding engagement of the two limiting grooves.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model uses the meshing transmission of the main bevel gear and the secondary bevel gear to facilitate the synchronous rotation of the two transmission gears. Both the transmission gear and the rack have a fixed number of teeth, so the meshing transmission between them has a fixed transmission ratio, which facilitates the displacement of the rack plate and the seedling tray by a specified distance. By setting the transmission gear to mesh with the leftmost tooth of the rack plate, it is easy to ensure that the seedling tray is accurately positioned directly below the seed adding station each time, avoiding misalignment of the chili seeds due to displacement deviation. This is especially suitable for the needs of chili seeds that are small and require precise insertion. By setting the transmission gear to mesh with the rightmost tooth of the rack plate, it is easy to remove the seedling tray from the shell after adding the seeds.

[0016] 2. This utility model uses bolts to easily lock and fix the seedling tray to the rack plate, and it is easy to disassemble, preventing the seedling tray from shifting randomly. The limiting block slides inside the limiting groove to limit both rack plates, effectively preventing the rack plates from shifting. Attached Figure Description

[0026] 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.

[0027] like Figures 1 to 5 As shown, this utility model provides a multi-hole synchronous sowing device for chili seedling trays, including a seed adding body 1. The seed adding body 1 is respectively equipped with a transmission component 2 and a displacement component 3. The surface of the seed adding body 1 is connected to a seed adding station 4 for easy seed adding. The surface of the seed adding body 1 is connected to a shell 5. The top inner side of the shell 5 is connected to a drive source 6, which has two power output ends. The inner side of the shell 5 is where a seedling tray 7 is placed for easy chili seedling cultivation. Both sides of the seedling tray 7 are connected to connecting blocks 8. The inner sides of the two connecting blocks 8 are threaded with bolts 9. A sealing door 10 is snapped onto one side of the shell 5.

[0028] The surface of the transmission assembly 2 is electrically connected to the two power output ends of the drive source 6 for driving the transmission assembly 2 to rotate.

[0029] The surface of the displacement component 3 is poweredly connected to the power output end of the transmission component 2 to drive the seedling tray 7 to make a quantitative displacement in the horizontal direction.

[0030] Specifically, the transmission assembly 2 includes two connecting rods 21 and two secondary bevel gears 23. The two connecting rods 21 are respectively set on the power output ends at both ends of the drive source 6. One end of each connecting rod 21 is connected to a main bevel gear 22. The two secondary bevel gears 23 are respectively meshed with the two main bevel gears 22 to facilitate the transmission rotation of the main bevel gears 22 and the secondary bevel gears 23. The bottom end of each secondary bevel gear 23 is connected to a fixing rod 24.

[0031] Furthermore, the two secondary bevel gears 23 are symmetrically arranged on the front and rear sides of the vertical center line of the housing 5, which facilitates the provision of symmetrical driving force and avoids skewing.

[0032] Furthermore, the displacement assembly 3 includes two transmission gears 31, two rack plates 32, and two limiting grooves 34. The two transmission gears 31 are respectively disposed at the bottom ends of the two fixed rods 24. The two rack plates 32 are respectively meshed with the two transmission gears 31 to facilitate driving the rack plates 32 to move horizontally. The bottom ends of the two rack plates 32 are connected to limiting blocks 33. The two limiting grooves 34 are both opened on the inner side of the bottom end of the housing 5.

[0033] It is worth noting that the bottom ends of both transmission gears 31 are rotatably connected to the inner bottom end of the housing 5 via bearings, which helps to improve the stability of the rotation of the transmission gears 31.

[0034] It is worth noting that the inner sides of the two rack plates 32 are respectively threaded to the surfaces of the two bolts 9, which facilitates the installation of the rack plates 32 to the seedling tray 7 and also facilitates disassembly.

[0035] It is worth mentioning that the longitudinal sections of the two limiting blocks 33 and the two limiting grooves 34 are all inverted "T" shapes. The surfaces of the two limiting blocks 33 are respectively engaged with the sliding grooves 34, which helps to improve the stability of the rack plate 32 translation.

[0036] The seed adding body 1, seed adding station 4, transmission gear 31, and rack plate 32 are existing technologies and will not be described in detail. Additionally, this utility model also includes a power supply, controller, and switch, which are not the main technical points of this patent and will not be described in detail. The "front, back, left, and right" perspectives of this device are... Figure 1 The direction shown in the diagram is the reference.

[0037] Working principle: First, the operator places the empty seedling tray 7 in the initial position. Then, the two connecting blocks 8 are slid into the two rack plates 32 respectively. Next, the two bolts 9 are screwed into the corresponding rack plates 32 and connecting blocks 8, thus fixing the seedling tray 7 to the two rack plates 32. Then, the drive source 6 is activated, driving the two connecting rods 21 to rotate. The two connecting rods 21 drive the two main bevel gears 22 and the two auxiliary bevel gears 23 to rotate in conjunction. This, in turn, drives the two fixed rods 24 and the transmission gear 31 to rotate simultaneously through the two auxiliary bevel gears 23. It should be noted that the initial position between the transmission gear 31 and the rack plate 32 is... The surface meshes with the rightmost rack of the rack plate 32. When the transmission gear 31 rotates, the rack plate 32 that meshes with it will gradually move to the right. That is, the two rack plates 32 gradually drive the seedling tray 7 to move into the interior of the shell 5 until the transmission gear 31 gradually rotates and meshes with the leftmost rack of the rack plate 32. At this time, the transmission gear 31 and the rack plate 32 lose their meshing force. At this time, the position of the rack plate 32 and the seedling tray 7 is positioned directly below the seed adding station 4. The seeding hole of the seedling tray 7 corresponds vertically to the position of the seed adding station 4. The seed adding machine 1 controls the seed adding station 4 to perform the sowing operation into the seedling tray 7.

[0038] After sowing is complete, restart the drive source 6. Drive the main bevel gear 22, secondary bevel gear 23, fixed rod 24 and transmission gear 31 to reverse their positions compared to before. At this time, the reverse transmission gear 31 re-engages with the rack of the rack plate 32. The two transmission gears 31 synchronously drive the two rack plates 32 to move to the left to reset and translate until the seedling tray 7 is moved out of the housing 5. Finally, remove the two bolts 9 from the corresponding rack plates 32 and connecting blocks 8 to remove the seedling tray 7. The operation is simple.
