Abstract

A structure concept of a peach kernel screening machine is disclosed as follows: the peach kernel screening machine mainly consists of a motor, a handle, a transmission mechanism, a rotary drum, a main shaft, a connecting part of the main shaft and the rotary drum, a nut scraping plate, a feeding hopper, a collecting box, a discharging hopper, a frame, a racket and fastening and positioning parts, and the transmission mechanism is internally provided with a double-overrunning mechanism which consists of an electric ratchet wheel sleeve, ratchet wheels and a manual ratchet wheel sleeve, and can rotate the rotary drum electrically and manually. When the electric operation is effective, the manual operation is ineffective, and otherwise when the manual operation is effective, the electric operation is ineffective, so that the rotary drum can be rotated electrically or manually.

Description

-kind of peach kernel screening machine structure theory

Technical field

The invention belongs to agricultural mechanical field.

Background technology

Known have sifting bed formula and a drum-type peach kernel screening machine.The sifting bed formula is driven the sifting bed level, teetertotters and screen through toggle by power source.Its shortcoming is that screening effeciency is low, low precision, noise is big, wasted work is many, known drum-type screening machine are used for peach kernel screening in enormous quantities; It is constructed as follows: cylinder divides two separately; The undersized peach kernel of first trommelling, large-sized peach kernel are discharged through second cylinder of lifting device entering from an end along cylinder and are carried out the screening of large-size.Large-sized peach kernel is discharged from an end along second cylinder; Garbled peach kernel gets into corresponding collecting box separately, and feed hopper and power source are at the same end of cylinder, and cylinder is from then on along downward-sloping; Rolling letter is placed on the support by locating wheel; One all chains are arranged on the garden outside cylinder one end, and motor drives a sprocket wheel after speed change, sprocket wheel cooperates the cylinder work that drives with chain.Its weak point is that the kind of drive of cylinder is to lean on cooperating of chain and sprocket wheel on the outer garden of cylinder one end; Occurring the cylinder two ends during use rolls asynchronous; Tube produces distortion, makes a soft-shelled turtle connect fractures such as gusset, and the longer fracture of tube is serious more; And frictional force, noise are all big, can only be electronic, wasted work is many.

Summary of the invention

The present invention will provide for middle-size and small-size peach kernel purchasing station-and kind of a peach kernel screening machine structure theory is used to roughly select, and satisfies the foreign exchange earning requirement to reduce big screening machine workload.

The present invention is constructed as follows: mainly by the coupling part of motor, handle, transmission mechanism, cylinder, main shaft, main shaft and cylinder, scrape grain plate, feed hopper, collecting box, discharge bucket, framework, support, fastening and locating element is formed, in transmission mechanism, realize two one-way elements electronic, manual revolving cylinder by one by what electronic ratchet sleeve, ratchet, manual ratchet sleeve were formed.Otherwise when electronic, manually inoperative, electronic inoperative when manual, realized electronic, hand rotation cylinder.Electronic ratchet sleeve, ratchet, manual ratchet sleeve are contained on the same main shaft; Main shaft is contained in and chassis base fastening two entad in the spherical bearing; The main shaft overhanging end joins through axle sleeve, spring, hitch and cylinder to be pressed, and spindle axis and the cylinder centre of gyration are arranged on the same axis, again owing to two entad uses of spherical bearing and spring; Realized when spindle axis is worked with the cylinder centre of gyration consistent, and keep running steadily, noise is little.

Advantage of the present invention:,, satisfy the requirement of quickening outlet to reduce big refiner workload because the present invention is for middle-size and small-size peach kernel purchasing station provides-kind of peach kernel screening machine structure theory.Experiment the present invention has reached selected requirement, thereby has accomplished certain selected workload, has quickened foreign exchange earning.Even but the present invention is owing to use two one-way elements can realize electronic, not have electricity of manual screening manual screening.Its screening precision height, efficient high (embodiment per hour selects one ton), volume is little, simple in structure, maintenance safe convenient, noise is low, laborsaving, power saving (implementing, motor power (output) is 370 watts), price are low.

The specific embodiment

Ratchet connects with main shaft with key; Electronic and manual ratchet sleeve is arranged on the ratchet axis direction both sides and leans on spherical bearing and main shaft to link; Main shaft support with chassis base fastening two entad in the spherical bearing, main shaft. cross and connect the axle sleeve that interior square sectional hole is arranged on the wadding, the external part outer casing spring is also located with packing ring, spiral shell nurse; Hitch and cylinder are fastening with screw, and cylinder other end below has two rubber wheels to support.This by main shaft, entad spherical bearing, axle sleeve connect rotary system that wadding, spring, cylinder and rubber wheel form move reduce, turn round steadily, friction minimizing, noise reduction; Be consistent easily when centre of the drum and spindle axis revolution; Stress is improved can reduce damage parts; Therefore security reliability improves, and wasted work also reduces, and motor makes cylinder rotate down at 15 rev/mins or 10 rev/mins through the belt wheel adjustable speed.Transmission is following: motor drives worm and gear through belt transmission and rotates, and worm-wheel shaft goes out end the second month in a season has a sprocket wheel to drive electronic ratchet sleeve by chain; Handle axis be placed on the fastening bearing block of chassis base in, on an end that stretches out, sprocket wheel is arranged, drive manual ratchet sleeve by chain, ratchet sleeve cooperates with ratchet and drives main shaft and cylinder rotation.Motor, worm-and-wheel gear, Handle axis bearing, the entad spherical bearing that both sides on the same axis of main shaft of two one-way elements are housed, axle sleeve hitch, cylinder, feed hopper, chestnut-wiping plate, two rubber wheels all are arranged in samely realizes zero to the framework of Lu Du adjustable tilt angle; With alignment pin and support location, the framework other end connects with support with hinges at the framework that feed hopper is arranged one end.Feed hopper, power drive mechanism are arranged in the two ends on the cylinder axis direction, and the cylinder axis of rotation can tilt to motor direction from feed hopper, this arrangement rationally, be convenient to maintenance and safe operation.

The present embodiment working condition is following: work like electronic mode; Drive the cylinder revolution through motor, belt, worm and gear, sprocket wheel, chain, electronic ratchet sleeve, ratchet, main shaft, axle sleeve hitch after the energized, peach kernel imports separately collecting box respectively and puts away from going out tadpole after feed hopper is by small size, large-size, three kinds of screenings of large scale.The peach kernel that the chestnut-wiping plate of cylinder outside will be stayed in the mesh is wiped the removing plug-hole off.As when not having electric hand to move, but winding by hand fixed handle beam warp sprocket wheel, chain, manually ratchet sleeve, ratchet, main shaft, axle sleeve hitch drive cylinder revolution work, and aluminium sheet manufacturing (also available plastics or nylon sheet) is selected in this enforcements screen cloth for use.
