Portable stand for efficiently filling jute sacks with dried chili peppers and cotton.

Abstract

A portable jute sack filling stand consisting of a collapsible base with lockable wheels, a height-adjustable pole, a sack opening support ring with quick-release clamp, and a removable funnel with a flexible rim, configured to guide dry chili peppers or cotton wool into the sack while minimizing spillage.

Description

Application area of ​​the invention

[0001] The invention relates to agricultural material handling equipment, in particular portable stands and devices that support and stabilize jute sacks during manual filling with light, bulky crops such as dried chili peppers and cotton. Background of the invention

[0002] Manually filling low-density bulk bags is labor-intensive, as workers must hold the bags open while transferring the contents, leading to fatigue, reduced work speed, and material waste. While simple stands and trolleys exist to stabilize the bags, many lack ergonomic height adjustment, self-opening chutes or rings to keep the opening open, leak-proof hoppers for loose or irregular material, or features that reduce repetitive lifting and bending. Agricultural handling literature and basic bag stands highlight the value of chutes / hoppers and sturdy supports. However, a mobile, adjustable, and user-friendly stand specifically designed for chili and cotton can further increase hourly bag throughput while reducing strain and waste. Summary of the invention

[0003] The invention comprises a lightweight, foldable stand with a retaining ring for the bag opening and a quick-release mechanism that holds a jute sack open at an adjustable height and angle. An attachable discharge funnel or chute guides dry chili peppers or cotton wool into the sack, and a foot-operated support facilitates the regular settling and compaction of the contents without the need to lift the sack manually. Integrated scales or hanging hooks simplify weight control, and the wide legs with casters allow for easy transport between different work areas, thereby increasing filling speed and working time.

[0004] In various configurations, the stand supports bags with a capacity of 25-100 kg, features telescopic columns with indexed settings to accommodate different worker heights, and offers a swiveling chute with a flexible skirt to minimize losses. Optional vibrating or tamping pads help compact flaky material, and a quick-release collar allows for rapid bag changes to maintain material flow. Detailed description

[0005] The frame consists of a collapsible base with two or three legs, providing a wide and stable footprint. Each leg is equipped with non-slip feet or lockable casters for easy transport between different storage locations. A central telescopic mast can be locked at various heights using spring-loaded bolts or clamps, making it suitable for different bag sizes and ergonomic requirements. The frame is constructed from lightweight steel or aluminum tubing to ensure a balanced combination of mobility and durability for agricultural use.

[0006] At the top of the pole, a round or oval retaining ring with a split collar clamp secures the bag's edge. The ring features a quick-release fastener, allowing full bags to be dropped onto the ground or a waiting cart without manual lifting. A soft seal along the ring improves the grip of the jute fibers, preventing slippage. A swivel bracket allows for minor angle adjustments to optimize material flow.

[0007] A detachable funnel, sized to match the typical opening of a jute sack, attaches above the ring. The funnel has a flexible bottom rim that overlaps inside the sack to catch any loose material. It is made of food-grade polymer or coated fabric to reduce friction with dried chili shells and cotton lint. The funnel can be adjusted to collect material from baskets, scoops, or a small conveyor belt.

[0008] A foot-operated settling aid is located near the base: either a pedal that gently lifts and taps the bottom of the bag over a padded plate, or a low-amplitude vibrating pad that assists in settling the material, reduces air pockets, and allows for more even packing without repeated manual shaking. The vibration intensity is limited for safety reasons and to protect delicate chili peppers. If used, power is supplied by a small battery with integrated wiring.

[0009] For weight control, a hook or platform scale can be integrated below the ring or at the base to display the approximate fill weight and thus minimize over- or underfilling. A simple mechanical dial scale reduces energy consumption and is also clearly visible outdoors. A visual display of the target weight promotes consistent filling.

[0010] The bag change is accelerated by the split collar clamp with cam lever; once the bag reaches the target weight, the operator releases the lever and the bag slides onto a pallet. A new bag is pushed over the ring and locked within seconds, minimizing downtime between fills.

[0011] Ergonomic features include rounded contact surfaces, adjustable grip positions on the funnel for secure alignment, and height adjustments that ensure a neutral elbow angle for the user, thus reducing fatigue. Optional shelves or hooks at shoulder height provide space for twine and labels for immediate sealing and labeling.

[0012] The stand can be folded by retracting the mast and pivoting the legs along the column, forming a compact package for transport in small vehicles or between different fields. Corrosion-resistant surfaces protect against dust and humidity; parts that have come into contact with chili oil can be easily wiped clean.

[0013] In operation, the operator positions the stand near the pile of material, adjusts the height, attaches an empty jute sack to the ring, and aligns the hopper. The material is poured or shoveled into the hopper; settling agent is used at regular intervals to compact the contents; the scale indicates the progress toward the target fill level; once the target weight is reached, the clamp is released to drop the sack onto a pallet, and a new sack is attached for the next cycle. This workflow reduces bending, manual holding, and spillage, thus enabling higher sack throughput and longer operating times.
