Description
Technical field
The utility model belongs to fruit screening installation field, is specifically related to pine tree screen for seeds screening device.
Background technology
Without existing full seed in the pine tree seed of screening, there is again deaf-seed, the most usually need that seed is carried out screening and remove deaf-seed.Screening effect aborning is to reduce seedling cost, and the effect in forestry is tested is to ensure that the reliability of follow-up test data, and conventional seed is Chinese pine and pinus yunnanensis, the larch of diameter 4-5mm of diameter 7-9mm.Screening technique conventional in each forest farm at present is selection by winnowing, is i.e. screened out by deaf-seed by wind-force with instruments such as dustpans, and this method efficiency is low and cannot thoroughly be screened out by deaf-seed.Usually utilizing density variation in laboratory, seed is screened by the method winnowed with liquid, and principle is exactly that the density of full seed is larger than deaf-seed, does not simply still have special screening container at present.
Utility model content
The utility model is in order to solve above-mentioned problems of the prior art, and the utility model provides pine tree screen for seeds screening device, make use of the characteristic of pine tree seed, dexterously by complete fruit and substandard products separately, and significant increase sorting efficiency.
The concrete technical scheme that the utility model uses is:
Pine tree screen for seeds screening device, including screening slot and screening plant, screening slot is trough body structure, screening plant is arranged in screening slot, described screening plant includes the first sieve plate, the second sieve plate and the 3rd sieve plate set gradually from top to bottom, and the second sieve plate is provided with the first vertical lifting rod, and the first sieve plate is sleeved on the first lifting rod, first lifting rod side is provided with the fixed plate of L-type, and the end of fixed plate forms spacing cooperation with screening slot sidewall.
It is provided with limited block, limited block and the first sieve plate on the first described lifting rod and forms spacing cooperation.
It is provided with the second lifting rod on the 3rd described sieve plate.
The 3rd described sieve plate lower end is provided with a bracer.
The first described sieve plate and the mesh size of the second sieve plate are 5-9mm, the staggered 45 ° of settings of screen cloth trend of the first sieve plate and the second sieve plate.
The mesh size of the 3rd described sieve plate is less than or equal to 1.5mm.
The beneficial effects of the utility model are:
The utility model, use the first sieve plate and the second sieve plate shifted to install, absolute alcohol liquid will be irrigated in screening slot, pine tree seed is put into screening slot, due to first, two holes diameter of sieve (perforated) plate are more than seed diameter, qualified, complete seed will sink in alcohol, and finally fall on the 3rd sieve plate, substandard products seed will float over liquid surface, by the first lifting rod, the second sieve plate is proposed, when the second sieve plate and the first sieve plate contact, one or two sieve plate associated movement, now the screen cloth of two sieve plates is overlapping, mesh aperture is reduced, the substandard products seed floating over liquid surface is pulled out, then the certified seed on the 3rd sieve plate is taken out, complete screening.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the schematic diagram during screen cloth coincidence of the first sieve plate and the second sieve plate；
In accompanying drawing, 1, screening slot, the 2, first sieve plate, the 3, second sieve plate, the 4, the 3rd sieve plate, the 5, first lifting rod, 6, fixed plate, 7, limited block, the 8, second lifting rod, 9, a bracer.
Detailed description of the invention
Below in conjunction with the accompanying drawings and specific embodiment the utility model is described in further detail:
The utility model is pine tree screen for seeds screening device, including screening slot 1 and screening plant, screening slot 1 is trough body structure, screening plant is arranged in screening slot 1, described screening plant includes the first sieve plate the 2, second sieve plate 3 and the 3rd sieve plate 4 set gradually from top to bottom, the first vertical lifting rod 5 it is provided with on second sieve plate 3, first sieve plate 2 is sleeved on the first lifting rod 5, first lifting rod 5 side is provided with the fixed plate 6 of L-type, the end of fixed plate 6 forms spacing cooperation with screening slot 1 sidewall, it is to avoid the first sieve plate 2 sinks to bottom land.
In order to avoid the second sieve plate 3 sinks to bottom land, the first described lifting rod 5 being provided with limited block 7, limited block 7 forms spacing cooperation with the first sieve plate 2.Ensure to leave space between first, second and third sieve plate.
3rd sieve plate 4 proposes for convenience, and the 3rd described sieve plate 4 is provided with the second lifting rod 8.
In order to avoid the 4th sieve plate 4 sinks to bottom land, the 3rd described sieve plate 4 lower end is provided with a bracer 9, makes to leave space between bottom land and the 3rd sieve plate 4 by a bracer 9, it is to avoid foreign material together pick up along with sieve plate.
In order to ensure preferable screening effect, the first described sieve plate 2 and the mesh size of the second sieve plate 3 are 5-9mm, the staggered 45 ° of settings of screen cloth trend of the first sieve plate 2 and the second sieve plate 3, it is to avoid the screen cloth line of the first sieve plate 2 and the second sieve plate 3 overlaps, the problem that screen size cannot reduce.As a example by ensure that the seed on the 3rd sieve plate 4 is pulled out completely, the mesh size of the 3rd described sieve plate 4 is less than or equal to 1.5mm.
nullSpecific embodiment 1，As shown in Figure 1，The utility model，Use the first sieve plate 2 and the second sieve plate 3 shifted to install，When first sieve plate 2 and the second sieve plate 3 misplace，As shown in Figure 2，Employing mesh size is 8-9mm，Two sieve plate upper screen cloth overlaps make 1/2nd of the front aperture that the mesh size after overlapping at least is reduced into，I.e. coincidence back aperture scope is less than 4.5mm，Less than average seed diameter，Absolute alcohol liquid will be irrigated in screening slot during use，Chinese pine or the pinus yunnanensis seed of diameter 7-9mm are put into screening slot，Due to first、Two holes diameter of sieve (perforated) plate are both greater than seed diameter respectively，Qualified、Complete seed will be through first、Two sieve plates sink to cell body lower end，And finally fall on the 3rd sieve plate，Substandard products seed will float over liquid surface owing to density is little，By the first lifting rod, the second sieve plate is proposed，When the second sieve plate and the first sieve plate contact，One or two sieve plate associated movement，Now the screen cloth of two sieve plates is overlapping，Mesh aperture is reduced，Make the substandard products seed floating over liquid surface because first overlapped cannot be passed through、Two sieve plates and pulled out，Then the certified seed on the 3rd sieve plate is taken out，Complete screening.
Specific embodiment 2, the close screen cloth that screen mesh size is 5-8mm that the sieve plate of lifting substandard products seed is arranged, the mesh size after now overlapping is less than 4mm so that equipment can screen the Larch Seed of diameter 4-5mm, mesh size is adjusted flexibly so that the range of application of equipment expands according to seed sizes.
