Description

Technical Field

[0001] This invention relates to the field of agricultural product processing workbench technology, and in particular to a foldable agricultural product processing workbench. Background Technology

[0002] With the large-scale development of modern agricultural planting industry, the harvest volume of various fruits, vegetables, grains and other agricultural products continues to increase. On-site pre-processing in the field has become an important part of the primary processing of agricultural products. Farmers often complete processing procedures such as raw material sorting, impurity removal and drainage in the field. The field operation environment is complex, with scattered plots and uneven ground. Conventional processing equipment is difficult to adapt to the changing field operation scenarios. Traditional fixed operating tables are not flexible enough due to structural limitations and cannot flexibly move with the harvesting team. Under this industry development environment, in order to adapt to the complex field conditions, an integrated agricultural product processing operating table that can be folded and transported has become the research and development direction of agricultural and forestry processing equipment.

[0003] Currently, most agricultural product processing workbenches on the market adopt a rigid steel frame structure welded as a whole. The support and the processing table are fixed together by welding. The overall size of the machine is fixed at the time of production and cannot be changed. Some processing tables equipped with casters can only move short distances by relying on the casters. The height of the equipment is determined by the prefabricated size of the steel frame and cannot be adjusted according to actual usage needs. When encountering uneven ground, operators generally use the crude method of using bricks, stones, and wooden boards to support the legs to level the equipment. Screening, draining and other processing steps are mostly used with independent single equipment placed separately.

[0004] The existing traditional processing workbench has a fixed, non-foldable structure, and the overall size of the machine cannot be compressed. It is difficult to load the equipment after processing one plot of land and transport it to the next plot. Due to the limited loading space of agricultural transport vehicles, it is difficult to transport the equipment with the vehicle. It is impossible to smoothly deploy the processing equipment in scattered small plots of farmland. When the equipment is not in use, the fixed cabinet also occupies a large area of ​​storage space, which significantly increases the cost of storing and transporting the equipment to the field for farmers, and seriously affects the efficiency of on-site processing of agricultural products. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a foldable agricultural product processing workbench, which solves the problems of agricultural product processing workbench mentioned in the background art.

[0018] Compared with existing technologies, the advantages of this invention are:

[0019] 1. The platform height is adjusted by sliding and rotating the cross-arranged support rods through the hydraulic rods. The extension length of the support blocks is controlled by adjusting the threaded column with the handwheel. This allows the operating table to be folded and stored, and the landing position to be leveled as needed. As a result, the equipment storage volume is reduced, and it can be placed stably on various uneven sites. This solves the problems of traditional processing tables being inconvenient to fold and transport, easy to shake when placed on uneven ground in the field, and difficulty in connecting different material feeding heights.

[0020] 2: The motor drives the cam roller to intermittently push the screening plate, and the spring force of the spring assembly drives the screening plate to reciprocate and reset, so as to achieve the purpose of automatic reciprocating vibration screening and grading of agricultural products, thereby achieving the effect of coarse and fine classification screening of materials and solving the problems of low efficiency of manual sorting and screening and uneven material grading.

[0021] 3: The drain frame filters out surface moisture from the materials. The accumulated water gathers along the guide structure and is discharged from the drain pipe. At the same time, the drain frame is fixed by spring-driven locking beads, so as to achieve continuous drainage of materials and secure fixation of the frame. This ensures that there is no water accumulation in the storage area and that the drain frame is not easy to fall off when the equipment is moved. It solves the problems of water-containing agricultural products being easily soaked in water and spoiling, and the material spilling due to the frame slipping off during transportation.

[0040] The rebound assembly 9 includes a connecting plate 901, a fixing plate 902, a limiting post 903, and a first spring 904. The bottom of the connecting plate 901 is fixedly connected to the top of the screening plate 801, and the connecting plate 901 moves up and down synchronously with the screening plate. The side wall of the fixing plate 902 is fixedly connected to the inner wall of the screening frame 3, and the fixing plate 902 fixes the installation position of the limiting post. The top of the limiting post 903 is fixedly connected to the bottom of the fixing plate 902, and the limiting post 903 restricts the sliding trajectory of the connecting plate to prevent deviation.

[0041] The storage frame 4 is fixedly connected to the receiving frame 11, which serves as the mounting base for the draining component. The receiving frame 11 is slidably connected to the draining frame 11, which holds the agricultural products with drained water. The draining frame 1101 has a drainage groove 1102 inside, which filters out the water seeping out of the material. The receiving frame 11 is fixedly connected to the limiting frame 11, which supports the draining frame and leaves a drainage gap. The bottom of the draining frame 1101 is attached to the top of the limiting frame 1104. The receiving frame 11 is equipped with a drainage component 12, which collects and discharges the water. The outer wall of the draining frame 1101 is fixedly connected to a pull rod 1103, which facilitates the pulling out of the draining frame.

[0042] The drainage component 12 includes a ramp 1201 and a beveled block 1202. The bottom of the ramp 1201 is fixedly connected to the inside of the receiving frame 11, and the ramp 1201 guides the flow of accumulated water in a directional manner using its slope. The side wall of the beveled block 1202 is fixedly connected to the side wall of the ramp 1201, and the beveled block 1202 collects the accumulated water to prevent it from overflowing. The bottom of the beveled block 1202 is fixedly connected to the inside of the receiving frame 11, and a drain pipe 1203 is fixedly connected to one end of the beveled block 1202. 1203 drains the accumulated water to the outside of the equipment. The outer wall of the drain frame 1101 is fixedly connected to a second fixing block 14. The second fixing block 14 works with a locking bead to achieve a snap-lock fixation. The outer wall of the storage frame 4 is fixedly connected to a first fixing block 13. The first fixing block 13 is used to install a limiting component. The bottom of the first fixing block 13 fits against the top of the second fixing block 14. A limiting component 15 is provided inside the first fixing block 13. The limiting component 15 locks the two fixing blocks to prevent the drain frame from loosening.

[0043] The limiting component 15 includes a locking ball 1501, which engages with the second fixing block 14. The locking ball 1501 limits the drain frame by engaging with the second fixing block 14. A limiting plate 1502 is fixedly connected to the top of the locking ball 1501. The limiting plate 1502 drives the locking ball to rise and fall synchronously. The limiting plate 1502 is slidably connected to the inner wall of the first fixing block 13. A second spring 1504 is fixedly connected to the top of the limiting plate 1502.

The top of the second spring 1504 is fixedly connected to the inner wall of the first fixing block 13. A telescopic rod 1503 is sleeved on the outer wall of the second spring 1504. The telescopic rod 1503 constrains the spring's extension and retraction path to prevent tilting. One end of the telescopic rod 1503 is fixedly connected to the top of the limiting plate 1502, and the other end of the telescopic rod 1503 is fixedly connected to the inner wall of the first fixing block 13.

[0044] In this invention, when moving and placing the processing worktable, the armrest 104 pushes the support 1 and the caster 101 to the desired position, and the processing worktable is moved to the desired position. When the ground is uneven, and it is necessary to ensure that the processing worktable 2 is in a stable state, the handwheel 605 is turned to drive the threaded column 603 to rotate and extend inside the fixed column 602. The threaded connection between the threaded column 603 and the fixed column 602 limits the extension and retraction adjustment of the threaded column 603, and at the same time drives the support block 606 to move synchronously. Thus, when the processing worktable 2 is uneven, the support length of the support block 606 is adjusted to make the processing worktable suitable for uneven positions. The leveling component places the processing worktable stably.

[0045] The first support rod 102 and the second support rod 103 are cross-displaced by the drive component 5, thereby adjusting the distance between the bracket 1 and the processing table 2, so as to fold the height of the processing table. This makes the processing table easy to transport after folding, and suitable for connecting the unloading ports of different heights after unfolding.

[0046] When agricultural products need to be screened and processed, the agricultural products are poured into the screening frame 3. Then, the motor 701 is started to drive the transmission shaft 702 and the cam roller 703 to rotate. The cam roller 703 acts and contacts the connecting block 704 to lift the connecting column 8 and the screening plate 801, causing them to slide up and down inside the screening frame 3. At the same time, the screening plate 801 is a multi-stage screening frame, which classifies materials of different sizes by screening apertures. When the screening plate 801 and the connecting column 8 slide up and down, the connecting plate 901 slides on the outer wall of the limiting column 903. During the sliding, the first spring 904 is compressed. Then, the first spring 904 releases its elasticity, causing the connecting plate 901 to drive the connecting column 8 and the screening plate 801 to reset, thereby achieving the purpose of multi-stage screening and classification of agricultural products.

[0047] After screening and sorting, the agricultural products are transported to the storage box 4 through the guide box 10. When the agricultural products are transported to the drain box 1101, the water in the agricultural products is drained out through the drain trough 1102. The excess water in the agricultural products is drained onto the drain component 12 inside the receiving box 11. The water is guided by the inclined plate 1201 and inclined block 1202 inside the drain component 12, and then the water is discharged through the drain pipe 1203, thereby achieving the purpose of draining the water inside the agricultural products during storage.

[0048] Meanwhile, the installation of the drain frame 1101 is achieved through the alignment of the first fixing block 13 and the second fixing block 14. The first fixing block 13 is provided with a limiting component 15. The locking bead 1501 in the limiting component 15 engages with the second fixing block 14, thereby limiting the position of the drain frame 1101. The locking bead 1501 is released by the second spring 1504, and can then be locked inside the second fixing block 14, thus achieving the effect that the drain frame 1101 is not easy to loosen or slide out when the processing table moves.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
