Description

Oil tea fruit hulling mechanism with extruding and rubbing functions

Technical Field

The utility model belongs to the technical field of agriculture and forestry equipment, a tea-oil camellia fruit hulling mechanism with extrude and rub function is related to.

Background

The tea-oil tree is also called tea tree, tea oil tree and white tea; belonging to the family Theaceae, evergreen small arbors. Because the seeds can be used for extracting oil (tea oil) for eating, the tea oil has the advantages of clear color, delicious taste, rich nutrition and storage resistance, is high-quality edible oil, and can also be used as lubricating oil and antirust oil for industry. The tea cake is not only a pesticide but also a fertilizer, and can improve the water storage capacity of the farmland and prevent and control pests in the rice field. The fruit peel is the raw material oil tea for extracting tannin extract, and is widely planted in the Hubei region to form a larger scale.

Because the husking is difficult and the fruit pulp is easy to be damaged, the manual husking production cost is high, and the market of the tea oil is influenced. The main reasons for the difficulty in mechanically shelling the oil-tea camellia fruits are as follows: firstly, the shell is hard, the crushing of the shell after drying needs higher pressure, and the pulp is easily damaged in the process of crushing the shell; secondly, the oil tea fruits are spherical or oval, have the diameter of 2-4 cm and wide size range, and can well protect the pulp in the shelling process after being subjected to complicated sorting and classification; thirdly, the tea oil fruit is generally divided into 3 chambers by spacers among fruit grains, each chamber is provided with 1 or 2 fruit pieces of seeds, and all the fruit pieces can be separated from the shells only by kneading; fourthly, sepals outside the shells and fruit stems possibly remained during fruit picking enable the camellia oleifera fruits not to roll easily, and difficulty is caused in particle size sorting.

The working principle of the shell removing mechanism is as follows:

crushing and scattering: the oil tea fruit which is matched with the width of the material selecting opening 23 can enter the material selecting groove, when the blocking portion 43 of the control ring 42 is positioned at the material selecting opening 23, the oil tea fruit cannot enter between the two pressure plates 36 due to the blocking of the material selecting opening 23, at this time, the two pressure plates 36 crush and scatter the oil tea fruit positioned between the two pressure plates 36, specifically, the rotating shaft 32 rotates and is acted by the limiting lug 41, the limiting portion 38 of the torsion spring 35 cannot cross the limiting lug 41 when the torsion spring 35 is twisted to a smaller degree, two ends of the torsion spring 35 are equivalently fixed on the rotating shaft 32 and the shaft sleeve 34 respectively, the number of turns of the torsion spring 35 is increased in the twisting process of the torsion spring 35, the torsion spring 35 is originally in a state that adjacent turns abut against each other, after the number of turns of the torsion spring 35 is increased, the height of the torsion spring 35 is increased, so that the rotation of the rotating shaft 32 can drive the shaft sleeve 34 and the pressure plates 36 fixed on the shaft sleeve 34 to move inwards, when the guide slider 62 is located in the straight section 63, the pressure plate 36 only translates inward, and when the guide slider 62 is located in the inclined section 64, the pressure plate 36 rotates at a certain angle in addition to translating inward, that is, the two pressure plates 36 perform the following actions: the two pressure plates 36 firstly translate under the condition of approaching each other and then rotate for a certain angle in opposite directions, and the distance between the two pressure plates 36 is further reduced in the rotating process, so that the advantages are as follows: the oil tea fruit between the two pressing plates 36 can be crushed firstly and then be scattered, and the pressure is continuously applied in the scattering process, so that the oil tea fruit pieces are separated from the shells, and the fruit pieces are separated from the spacers for separating the oil tea fruit chambers as much as possible.

The oil tea fruit enters between two platens 36: when the feeding portion 44 of the control ring 42 is located at the material selecting port 23, the blocking portion 43 is located below the feeding portion 44, the oil tea fruit at the material selecting port 23 can enter between the two pressing plates 36 through the feeding portion 44, due to the existence of the blocking portion 43, the oil tea fruit can be left in the space formed by the two pressing plates 36 and the blocking portion 43 after entering between the two pressing plates 36, the existence of the flange 46 can ensure that the oil tea fruit between the two pressing plates 36 is not located at the edge of the pressing plate 36, so as to avoid the oil tea fruit from jumping out from the edge of the pressing plate 36 during the crushing process, during the feeding process, the limiting portion 38 of the torsion spring 35 already passes over the limiting projection 41, and the limiting portion 38 of the torsion spring 35 is in a state of rotating relative to the shaft sleeve 34, so that the torsion spring 35 is not affected by the torsion force during the feeding process, i.e. the distance between the two pressing plates 36 is kept unchanged, until the limiting portion 38 of the torsion spring 35 meets the limiting projection again, the control ring 42 rotates half a turn, and the above crushing and rubbing state is performed, and the above operation is repeated, so that the camellia oleifera fruits can be continuously hulled.

Sorting oil tea fruits:

in order to enable the oil-tea camellia fruits to respectively enter the corresponding hulling mechanisms from small to large according to the sizes, a material selecting port 23 matched with the corresponding hulling mechanisms is arranged at the bottom of the obliquely arranged material guide channel 21, namely: by head end to the end of guide channel 21, the width of the selection mouth 23 that sets gradually progressively increases, and only can not supply the selection mouth 23 next to select separately through the oil tea fruit of the selection mouth 23 of less width, for this reason, need make the oil tea fruit remove in guide channel 21 orderly, ensure that the oil tea fruit that gets into in proper order can obtain the selection that corresponds selection mouth 23 in proper order.

Specifically, the oil tea fruits with different sizes enter from the feeding hopper 22, a feeding storage area is formed between two adjacent stirring pieces 74 on the outer side surface of the conveying belt 73, the conveying belt 73 continuously and sequentially conveys the oil tea fruits in the feeding hopper 22 into the material selecting groove in the rotating process, and the rotating speed of the control ring 42 is higher due to the lower running speed of the conveying belt 73; that is to say, it needs to be ensured that the control ring 42 rotates a whole circle, the single feeding and storing area still can not all pass through the corresponding material selecting opening 23, it is ensured that all the oil-tea fruits which can enter the material selecting opening 23 in the feeding and storing area can both enter between the two pressing plates 36, only the oil-tea fruits which can not pass through the corresponding material selecting opening 23 after being completely sorted can enter the next material selecting opening 23, and the sorting of the next material selecting opening 23 is accepted, so that all the oil-tea fruits can enter the hulling mechanism corresponding to the grain size after the grain size is sorted.

The camellia oleifera fruits which cannot pass through all the material selecting openings 23 due to the sepals and the residual fruit stalks outside the shells can be returned to the material feeding hopper 22 under the action of the conveying belt 73, and the fruit stalks and the sepals of part of the camellia oleifera fruits can be peeled off in the process of mutually extruding and turning the camellia oleifera fruits in the material feeding hopper 22. Of course, the situation that the positions of the oil-tea camellia fruits are not correct, two oil-tea camellia fruits are extruded side by side, and the like can also cause that the oil-tea camellia fruits cannot enter the material selecting opening 23, and the oil-tea camellia fruits enter the material feeding hopper 22 again to be selected and fed again.
