Abstract

The invention relates to a peanut huller which is characterized by comprising a feeding hopper, a rotary drum, a rotary drum shaft, a notch board sieve, a material collecting drum, a material receiving board, a motor and a rack; the exterior of the rotary drum is fixed with an inverted cone-shaped vertical type hollow drum with spiral bulged ribs; the notch board sieve is also in an inverted cone shape; the annular hulling region between the rotary drum and the notch board sieve is gradually contracted from top to bottom; and the upper end of the rotary drum is provided with a cone-shaped uniform distributor with a spiral rib board. The peanut huller has the advantages that a vertical type hulling mode is adopted; the large area of the notch board sieve is effectively utilized and the hulling speed is enhanced so as to enhance the hulling efficiency; the rapid separation of peanuts from the hulling region is realized so as to avoid the peanuts from remaining in the hulling gap; the damage is decreased so as to reduce the damage rate of the peanuts; thus, the peanut huller can automatically adapt to the actual condition of different shape sizes of the peanuts; the hulling damage is lightened, and the completely hulling rate and the hulling efficiency are enhanced; and the hulling gap can be adjustable to adapt to the hulling of the peanuts with different varieties and shape sizes.

Description

A kind of groundnut sheller

Technical field

The present invention relates to a kind of agricultural machinery, particularly a kind of groundnut sheller to the shelling of peanut fruit

Background technology

People all adopt horizontal groundnut sheller that peanut pod is shelled at present, the critical piece of its hulling machine is that cage (hulling drum) and grizzly bar concave grate are beaten in the shelling of open type, the shelling principle be by the shelling that high speed horizontally rotates beat cage strike, push and rub peanut pod, make that the peanut pod is broken, fragmentation, the broken shell of the shelled peanut of broken shell and peanut is then separated from the grizzly bar concave grate, peanut shell is blown out from impurity discharging port by the air-flow of blower fan afterwards, and shelled peanut flows on the vibratory sieve of inclination the screening back and flows out.

This horizontal groundnut sheller remains in certain shortcoming: its grizzly bar concave grate is a semi-cylindrical shaped, and effectively work area is little, screen capacity is low, causes complete machine shelling efficient low; Shelled peanut, peanut shell after the peanut of feeding and the shelling, under the gravity effect, mainly concentrate on the limited concave grate bottom of area, form the thicker bed of material, because the bed of material is thick, the effective area of concave grate is little, and the shelled peanut after the shelling can not be separated rapidly, thereby shelled peanut, peanut shell are entrained in peanut pod in the shelling district, increased the time of staying in the shelling gap and stirred number of times, thereby increased the damage probability, shelling back shelled peanut breakage rate is higher; Be difficult to the to shell adjusting in gap of traditional horizontal groundnut sheller, thus poor for applicability to the shelling of different cultivars peanut

Summary of the invention

The purpose of this invention is to provide a kind of simple in structurely, damage ratio is low, and the shelling effect is better, high efficiency, the groundnut sheller that the gap of can realizing shelling is adjusted.

For achieving the above object, the technical solution adopted in the present invention is: comprise feeding hopper, cylinder, drum shaft, concave grate, aggregate tube, the plate that connects material, motor and frame, it is characterized in that: cylinder is the vertical hollow cylinder of back taper that outer surface is welded with the spiral salient rib, concave grate is similarly the back taper bodily form, and shrink from top to bottom gradually in ring-type shelling district between the two; The upper end of cylinder is provided with the cone-shaped uniform device of band spiral gusset.

Be welded with disk in the above-mentioned cylinder, drum shaft is connected on the disk by connecting key and nut.

Above-mentioned concave grate is constituted by the fan-shaped grizzly bar notch board of polylith, and the grizzly bar notch board is provided with oblique grizzly bar, and the grizzly bar direction is identical with spiral rib rotation direction on the cylinder.

The interval crack of shelling between above-mentioned cylinder and the concave grate is 30mm-50mm.

Good effect of the present invention is:

1, adopt vertical shelling pattern, concave grate effectively utilizes the area height, has improved shelling speed, thereby improves shelling efficient.

2, peanut pod is under the cone-shaped cloth device centrifugal force and gravity acting in conjunction of rotation, enter the shelling gap with forming uniform thin layer, continuous-flow, realized that shelled peanut separates rapidly in the shelling district, thereby the stop of shelled peanut in the shelling gap, be subjected to the shelling effect of parts have once more been avoided, reduce damage, thereby reduced the breakage rate of shelled peanut.

3, Because shrink from top to bottom gradually in the shelling of the ring-type between back taper hulling drum and concave grate district, peanut pod flows downward in the process, be subjected to decrustation earlier and broken shell than the major peanut fruit, when moving downward, less peanut progressively is subjected to decrustation, thereby can adapt to peanut profile actual conditions not of uniform size automatically, alleviate the shelling damage and improved threshing performance and shelling efficient.

4, adopt being threaded of cylinder and drum shaft, realized the shelling adjustable gaps, thereby realized that a machine shells to the peanut of different cultivars, different appearance and sizes.

Sequence number explanation among the figure: frame 1, motor 2, belt drive unit 3, the plate 4 that connects material, drum shaft 5, aggregate tube 6, concave grate 7, cylinder 8, feeding hopper 9, traffic controller 10, uniform device 11, uniform device spiral gusset 12, clutch disk 13, cylinder rib 14, nut 15, bearing block 16.

The specific embodiment

See Fig. 1-4, concrete structure is as follows: bearing block 16 is set on frame 1, rotates assembling drum shaft 5 on the bearing block 16; Drum shaft 5 connects motor 2 by belt drive unit 3.Assembling aggregate tube 6 on frame 1, the below of aggregate tube 6 is provided with the plate 4 that connects material of inclination; In the upper end of frame 1 feeding hopper 9 is set, drawing and pulling type traffic controller 10 is set on the feeding hopper 9.The below of feeding hopper 9 is provided with cylinder 8, cylinder 8 is the vertical hollow cylinders of back taper, many uniform spiral salient ribs 14 of its outer surface welding, the upper end of cylinder 8 is provided with cone-shaped uniform device 11,8 spiral gussets 12 evenly distribute on the uniform device 11, play guide functions, make the peanut that falls evenly enter the shelling interval.Take off to weld in the cylinder and go up lower disc 13, drum shaft 5 is connected on the disk 13 by connecting key and nut 15.Regulate the position of cylinder on drum shaft by nut 15, thereby realize the interval adjustable gaps of shelling.

At the outer setting concave grate 7 of cylinder 8, concave grate 7 is similarly the back taper bodily form, and shrink from top to bottom gradually in ring-type shelling district between the two; The interval crack that shells is 30mm-50mm.Concave grate 7 is welded into by a plurality of sector element sieve sheets, and each sieve unit sheet is provided with oblique angle grizzly bar 7-1, and grizzly bar is oblique consistent with spiral rib 14 rotation directions on the cylinder.

Operation principle:

During use, open motor, peanut pod is inserted feeding hopper, peanut pod is brought in the gap of cylinder and concave grate, and cylinder 8 rotates, and concave grate 7 maintains static, and utilizes swing roller that rubbing between the hitting power of peanut and peanut and the peanut shelled.Thereby shelling back shelled peanut falls into discharge zone and finishes the shelling process.Regulate the position of cylinder 8 on drum shaft by nut 15, thereby realize shelling interval gap adjustment, realize the peanut of different cultivars is shelled
