Embodiment
Below in conjunction with specific embodiment, the invention will be further described.
Embodiment 1
Embodiment 1 is step（1）Throwing fruit machine used.
As shown in Figure 1 to Figure 3, the throwing fruit machine that the present invention is provided includes frame 1 and shelling crushing part, and shell crushing part
In frame 1, shelling crushing part includes screen drum 2, roller 3 and drive system 4, and drive system 4 is used to drive 3 turns of roller
Dynamic, screen drum 2 is fixed in frame 1, and the rotary type of roller 3 is sheathed in the inner chamber of screen drum 2, and roller 3 is that periphery is more than two-stage
Cylindrical hierarchic structure, its periphery cylinder cascaded surface is used to break the brush pawls 31 of camellia oleifera fruit shell provided with multiple, multiple
Up big and down small gap is formed between the end of brush pawl 31 and screen drum 2, i.e., from top to bottom, between multiple ends of brush pawl 31 and screen drum 2
Gap be gradually reduced, realize the purpose for the crushing that can carry out shelling very well to the camellia oleifera fruit of variable grain size.
The present embodiment throws fruit machine when in use, and the driving roller 3 of drive system 4 is rotated, and then drives multiple brush pawls 31 to rotate.
Camellia oleifera fruit for shelling enters in screen drum 2 from the top of screen drum 2, breaks the fruit of camellia oleifera fruit by brush pawl 31 during sinking
Shell, to play a part of shelling, the bottom dropped out of tea seed after shelling from screen drum 2.In the manner described above, camellia oleifera fruit for shelling
Out of, screen drum 2 top feeding screen drum 2, heat treatment constantly is completed again from the bottom dropped out of screen drum 2 after shelling completely,
I.e. the throwing fruit machine can continuously carry out heat treatment to camellia oleifera fruit, and make it that camellia oleifera fruit shelling is complete, simultaneously, it is to avoid oil
The situation of broken seed occurs in de-hulling process for tea fruit.
The throwing fruit machine not only has the effect easily shelled, it is often more important that can be crushed in time after shelling, because de-
After shell, the tea seed of camellia oleifera fruit is heavier, smaller and relatively harder, and shell is larger, in sinking watching easily by brush pawl 31 more
Many grindings, and because shell is more crisp, the shell taken off can be easy to be grated, and to be kept as comparison intact for tea seed；Really
Shell advantageously separates processing in shell after crushing with the postorder of tea seed.The throwing fruit machine not only have it is simple in construction, be easy to make,
Cost is low, shelling efficiency high and the good advantage of shelling effect, also has the advantage for crushing the camellia oleifera fruit shell after shelling concurrently.
In the present embodiment, the angle axially horizontal by 60 ° of screen drum 2 is conducive to camellia oleifera fruit for shelling to sink.
It is 80mm positioned at the distance between the end of brush pawl 31 of the top and screen drum 2 in further technical scheme；Positioned at bottom
The distance between the end of brush pawl 31 and screen drum 2 are 25mm, and the size of the distance and camellia oleifera fruit is adapted, and is easy to grinding camellia oleifera fruit fruit
Shell.The roller 3 of the present embodiment is laminated by level Four cylinder table, and from top to bottom increase forms circle to the outside diameter of cylinder table successively
Cylindricality hierarchic structure, during camellia oleifera fruit is to sinking, the brush pawl 31 positioned at the top carries out thick heat treatment to camellia oleifera fruit,
Then heat treatment is further carried out to camellia oleifera fruit by centrally located brush pawl 31 and crushes the shell after shelling.More past
Under process in, brush pawl 31 and screen drum 2, which coordinate, makes camellia oleifera fruit shell and crush the shell after shelling.Finally by positioned at bottom position
The brush pawl 31 put coordinates with screen drum 2 makes camellia oleifera fruit shell and crush completely the shell after shelling, the obtained tea seed after shelling with
The shell of crushing reaches the requirement of later separation processing.
As shown in Figures 4 to 6, the length of brush pawl 31 of the present embodiment is 25mm；Brush pawl 31 is in cylinder, the diameter of brush pawl 31
For 0.6mm, the cylindrical cascaded surface in periphery of roller 3 every square centimeter improves shelling and crushes shell provided with 20 brush pawls 31
Effect.
As shown in fig. 7, in the present embodiment, screen drum 2 includes offering multiple through holes on cylindrical base member 21, cylindrical base member 21
22, multiple through holes 22 are arranged around the circumferential array of cylindrical base member 21.Through hole 22 is in bar shaped, and the length of through hole 22 is 30mm, wide
Spend for 7mm, be easy to the shell fragments after more crushing directly to be discharged from through hole 22, play certain separating effect.
As shown in Figure 1 to Figure 3, the two ends insertion of cylindrical base member 21, shelling part also includes the upper port for being covered on screen drum 2
Cover plate 5 and the feed hopper 6 installed in the top of cover plate 5, offer the charging aperture that fuel feeding tea fruit is passed through on cover plate 5, feed hopper 6 leads to
Cross charging aperture to connect with cage cylinder, be easy to concentrate charging.
In the present embodiment, equipment also includes the protective cover 7 being arranged in frame 1, and screen drum 2 is located in protective cover 7, is easy to receive
Collect and eliminate safe hidden trouble.
As shown in Figures 1 to 6, in the present embodiment, roller 3 includes rotating shaft 32, and rotating shaft 32 is arranged on frame 1 by bearing
On, drive system 4 includes motor, and motor is connected by belt with rotating shaft 32.The drive system 4 of the present embodiment is arranged on frame 1
On so that the compact conformation of the equipment, occupy little space.
