Description

Technical Field

[0001] The present invention relates to the technical field of wolfberry screening, and in particular to a wolfberry screening device and method. Background Art

[0002] Fresh wolfberries are mostly oval in shape, and the fuller ones, such as those with a longer long diameter and a wider short diameter, are of better quality. In order to screen out the fuller wolfberries among the fresh wolfberries, most of the existing methods use a vibrating screen or a rolling screen to better screen the fresh wolfberries. However, whether it is the vibrating screen or the rolling screen, the screening methods of both are orderly, which makes the screening effect of fresh wolfberries poor during the screening process. Summary of the invention

[0003] In order to solve the above technical problems, the present invention is solved by the following technical solutions.

[0004] A wolfberry screening device comprises a device body, the device body has a screening slot which is inclined along the length direction and opened on one side upward; the higher side of the screening slot forms a feed side, and the lower side of the screening slot forms a discharge side; a plurality of elliptical screening holes are provided on the bottom wall of the screening slot, the screening holes are used to screen the material to be screened, the qualified material after screening falls from the discharge side, and the unqualified material after screening falls from the bottom of the screening slot; a spreading mechanism and a posture adjustment component are sequentially arranged above the screening slot in the direction from the feed side to the discharge side, the spreading mechanism is used to spread the material to be screened, and the posture adjustment component is used to adjust the posture of the material to be screened.

[0005] When the device body provided in the present invention is actually used, the user pours the wolfberries to be screened to the feed side of the screen slot. Since the screen slot is inclined, the wolfberries to be screened can move along the bottom wall of the screen slot from the feed side to the discharge side. Firstly, under the action of the paving mechanism, the wolfberries to be screened can be better spread out to one layer with multiple layers of wolfberries to be screened, so that it is better to facilitate the sieve holes to screen out unqualified wolfberries and to facilitate qualified wolfberries to roll to the discharge side and fall out; secondly Under the action of the posture adjustment component, the wolfberries to be screened are mostly oval in shape and of different sizes. The qualified wolfberries of the present invention are full, such as those with a longer long diameter and a wider short diameter, and the unqualified wolfberries are unfull, such as those with a longer long diameter and a thinner short diameter, a shorter long diameter and a wider short diameter, and a shorter long diameter and a thinner short diameter. Therefore, the posture adjustment component can adjust the posture of the wolfberries to be screened during the screening process, so that the unqualified wolfberries can fall from the bottom of the screening slot, and the qualified wolfberries can fall from the discharging side.

[0006] Compared with the prior art, the device body provided by the present invention can adjust the posture of wolfberries by the posture adjustment component during the screening process, so that the wolfberries can be screened more quickly. For example, unqualified wolfberries can change their posture and meet the screening conditions of the sieve holes and fall at the sieve holes, while qualified wolfberries will not meet the screening conditions of the sieve holes and fall at the discharge side no matter how their posture changes; therefore, the screening effect of wolfberries is better improved.

[0007] Preferably, a material dropping chute parallel to the sieve slot is provided below the sieve slot, and a material dropping opening is formed on the material dropping chute near the discharge side; the material dropping chute is used to receive the unqualified materials after screening, and the unqualified materials after screening are dropped from the material dropping opening.

[0008] In the present invention, the unqualified wolfberries after screening are preferably collected by setting the material dropping chute.

[0009] Preferably, a bracket assembly is provided at both the sieve slot and the blanking chute; the bracket assembly includes two side frames respectively arranged on both sides of the sieve slot and the blanking chute, and the corresponding parts of the lower ends of the two side frames are connected by a plurality of cross frames; the two side frames are respectively provided with a first mounting port and a second mounting port for installing the sieve slot and the blanking chute, the corresponding part of the side wall of the sieve slot is provided with a first mounting column for cooperating with the first mounting port, and the corresponding part of the side wall of the blanking chute is provided with a second mounting column for cooperating with the second mounting port; and the two side frames are provided with mounting parts for installing the paving mechanism and the posture adjustment assembly.

[0010] Through the above structure, the bracket assembly can better install the screening slot and the material dropping slot, and can better install the paving mechanism and the posture adjustment assembly, so as to better realize the screening of the wolfberries to be screened.

[0011] Preferably, the paving mechanism comprises a mounting plate arranged above the sieve slot, the mounting plate is provided with bristles toward the bottom wall of the sieve slot, and the corresponding ends of the bristles are used to spread the material to be screened.

[0012] In the present invention, the paving mechanism can preferably pave the wolfberries to be screened, so that the wolfberries stacked in multiple layers can be preferably spread into one layer after passing through the paving mechanism, thereby making it easier for the sieve holes to screen the wolfberries to be screened.

[0013] Among them, according to the distribution of the center of gravity of wolfberries, wolfberries generally do not stand upright in the sieve slot but are in a "lying" state, which also provides objective conditions for the wolfberries to be screened to roll in the inclined sieve slot. Furthermore, the distance between the tip of the bristles and the bottom wall of the sieve slot is basically consistent with the inner diameter of qualified wolfberries, which enables the wolfberries to be screened to remain in a better rolling state after the action of the flattening mechanism.

[0014] Preferably, the posture adjustment assembly includes a first posture adjustment mechanism and a second posture adjustment mechanism which are arranged at intervals above the screen slot and cooperate with each other. The first posture adjustment mechanism and the second posture adjustment mechanism both include an installation box, the installation box forms an installation cavity with one side opening upward, and a driving mechanism and an adjustment mechanism are provided in the installation cavity. The driving mechanism is used to drive the adjustment mechanism. The adjustment mechanism includes a plurality of rotating rods which are arranged at the bottom wall of the installation cavity and are evenly spaced along the length direction of the installation cavity. One end of the rotating rod extends out of the bottom wall of the installation cavity and a turntable is provided at the extended end. A brush strip is provided on the turntable toward the bottom wall of the screen slot, and the brush strip is used to adjust the posture of the material to be screened. The rotation directions of adjacent rotating rods in the same installation cavity are opposite, and the rotation directions of adjacent rotating rods in different installation cavities are opposite.

[0015] In the present invention, the wolfberries to be screened can change their posture under the action of the first posture adjustment mechanism and the second posture adjustment mechanism, so that the sieve holes can better screen out unqualified wolfberries, so that qualified wolfberries can pass through the posture adjustment component and then roll out from the discharge side;

[0016] Specifically, the rotating rods at the first posture adjustment mechanism and the second posture adjustment mechanism rotate, and the rotation directions of adjacent rotating rods in the same installation cavity are opposite, and the rotation directions of adjacent rotating rods in different installation cavities are opposite, which enables the brush strips at the ends of the rotating rods to better force the wolfberries to be screened at the sieve slot to adjust their posture in a more disordered state, so that during the screening process, the wolfberries to be screened have a more disordered posture change, so that unqualified wolfberries can better pass through the sieve holes, while qualified wolfberries fall from the discharge side along the bottom wall of the sieve slot;

[0017] Compared with the prior art, the present invention can adjust the posture of the wolfberries during the screening process when screening wolfberries so that unqualified wolfberries can better fall from the sieve holes into the drop trough, while qualified wolfberries fall from the discharge side along the bottom wall of the sieve trough, thereby better improving the screening effect of wolfberries.

[0018] Preferably, the driving mechanism includes a driving rod arranged along the length direction of the mounting cavity, the axial direction of the driving rod is perpendicular to the axial direction of the rotating rod, a first bevel gear is provided at the end of the rotating rod located in the mounting cavity, and a plurality of second bevel gears are provided along the axial direction of the driving rod, respectively used to mesh with the corresponding first bevel gears; a pulley is provided at the end of the driving rod extending out of the mounting box, and the pulley is used to connect to the power component.

[0020] Preferably, a rotating shaft with one end extending out of the bottom wall of the mounting cavity is respectively provided on both sides of the inner wall of the mounting cavity in the length direction, and one end of the rotating shaft extending out of the mounting cavity extends to the bottom wall of the sieve slot; a matching portion is formed at the corresponding portion of the bottom wall of the sieve slot, and an elliptical matching cavity is formed at the matching portion, and one end of the rotating shaft extends into the matching cavity and is provided with a curved block;

[0021] A third bevel gear is provided at the end of the rotating shaft located in the installation cavity, and a fourth bevel gear for meshing with the third bevel gear is provided at the driving rod; the rotating shafts in the same installation cavity rotate in the same direction and the rotating shafts in different installation cavities rotate in the same direction;

[0022] A compression spring is arranged between the first mounting column at the side wall of the screen slot and the outer wall of the side frame, and the first mounting column is matched with the first mounting opening through a straight bearing.

[0023] In the present invention, when the driving rod rotates in the installation cavity under the action of the power component, the curved block at the rotating shaft can reciprocate against the inner wall of the matching cavity, and cooperate with the compression springs and linear bearings on both sides of the screen slot, so that the screen slot can be better rocked back and forth in the horizontal direction, thereby better accelerating the speed of wolfberries rolling on the bottom wall of the screen slot, avoiding the wolfberries from blocking the screen holes, and cooperating with the posture adjustment component to achieve the posture adjustment of the wolfberries to be screened in a more disordered rolling state at the bottom wall of the screen slot.

[0040] In order to further understand the content of the present invention, the present invention is described in detail in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are only for explaining the present invention and are not intended to limit it.

[0041] Example 1

[0042] like Figure 1-9As shown, the present embodiment provides a wolfberry screening device, which includes a device body 100, and the device body 100 has a screen slot 110 which is inclined along the length direction and has one side open upward; the higher side of the screen slot 110 forms a feed side 111, and the lower side of the screen slot 110 forms a discharge side 112; the bottom wall of the screen slot 110 is provided with a plurality of elliptical screen holes 120, and the screen holes 120 are used to screen the material to be screened, and the qualified material after screening falls from the discharge side 112, and the unqualified material after screening falls from the bottom of the screen slot 110; above the screen slot 110, a paving mechanism 130 and a posture adjustment component 140 are sequentially arranged in the direction from the feed side 111 to the discharge side 112, the paving mechanism 130 is used to spread the material to be screened, and the posture adjustment component 140 is used to adjust the posture of the material to be screened.

[0043] When the device body 100 provided in this embodiment is actually used, the user pours the wolfberries to be screened to the feed side 111 of the screen slot 110. Since the screen slot 110 is inclined, the wolfberries to be screened can move along the bottom wall of the screen slot 110 from the feed side 111 to the discharge side 112. First, under the action of the paving mechanism 130, the wolfberries to be screened can be better spread out to one layer with multiple layers of wolfberries to be screened, so that it is better to facilitate the sieve hole 120 to screen unqualified wolfberries and to facilitate the qualified wolfberries to roll to the discharge side 112. Side 112 falls; secondly, the wolfberries to be screened are subjected to the action of the posture adjustment component 140. Since most wolfberries are elliptical and of different sizes, the qualified wolfberries in this embodiment are plump, such as those with a longer long diameter and a wider short diameter, and the unqualified wolfberries are unfull, such as those with a longer long diameter and a thinner short diameter, a shorter long diameter and a wider short diameter, and a shorter long diameter and a thinner short diameter; therefore, the posture adjustment component 140 can adjust the posture of the wolfberries to be screened during the screening process, so that the unqualified wolfberries can fall from the bottom of the screening slot 110, and the qualified wolfberries can fall from the discharge side 112.

[0044] Compared with the prior art, the device body 100 provided in the present embodiment can adjust the posture of wolfberries by the posture adjustment component 140 during the screening process, so that the wolfberries can be screened more quickly. For example, unqualified wolfberries can change their posture and meet the screening conditions of the sieve holes 120 and fall at the sieve holes 120, while qualified wolfberries will not meet the screening conditions of the sieve holes 120 and fall at the discharge side 112 no matter how their posture changes; therefore, the screening effect of wolfberries is better improved.

[0045] like Figure 5 As shown, in this embodiment, a material drop chute 150 parallel to the sieve slot 110 is provided below the sieve slot 110, and a material drop opening 520 is formed near the discharge side 112 of the material drop chute 150; the material drop chute 150 is used to receive the unqualified materials after screening, and the unqualified materials after screening fall from the material drop opening 520.

[0050] In this embodiment, the spreading mechanism 130 can better spread the wolfberries to be screened, so that the wolfberries stacked in multiple layers can be better spread into one layer after passing through the spreading mechanism 130, so it is better for the sieve holes 120 to screen the wolfberries to be screened.

[0051] Among them, according to the distribution of the center of gravity of wolfberries, wolfberries generally do not stand upright in the sieve slot 110 but are in a "lying" state, which also provides objective conditions for the wolfberries to be screened to roll in the inclined sieve slot 110. Furthermore, the distance between the tip of the bristles 720 and the bottom wall of the sieve slot 110 is basically consistent with the inner diameter of qualified wolfberries, which enables the wolfberries to be screened to remain in a better rolling state after the action of the flattening mechanism 130.

The adjustment mechanism includes a first rotating rod 820 which is arranged at the bottom wall of the installation cavity 910 and is evenly spaced along the length direction of the installation cavity 910. One end of the first rotating rod 820 extends out of the bottom wall of the installation cavity 910 and a turntable 830 is provided on the extended end. The turntable 830 is provided with a brush strip 840 facing the bottom wall of the screen slot 110. The brush strip 840 is used to adjust the posture of the material to be screened; the rotation directions of adjacent first rotating rods 820 in the same installation cavity 910 are opposite, and the rotation directions of adjacent first rotating rods 820 in different installation cavities 910 are opposite.

[0053] In this embodiment, the wolfberries to be screened can change their posture under the action of the first posture adjustment mechanism 141 and the second posture adjustment mechanism 142, so that the sieve hole 120 can better screen out unqualified wolfberries, so that qualified wolfberries can pass through the posture adjustment component 140 and then roll out from the discharge side 112;

[0054] Specifically, the first rotating rods 820 at the first posture adjustment mechanism 141 and the second posture adjustment mechanism 142 rotate, and the adjacent first rotating rods 820 in the same installation cavity 910 rotate in opposite directions, and the adjacent first rotating rods 820 in different installation cavities 910 rotate in opposite directions, which enables the brush strips 840 at the ends of the first rotating rods 820 to better force the wolfberries to be screened at the sieve slot 110 to adjust their posture in a relatively disordered state, so that during the screening process, the unqualified wolfberries can better pass through the sieve holes 120 due to the disordered changes in the posture of the wolfberries to be screened, while the qualified wolfberries fall from the discharge side 112 along the bottom wall of the sieve slot 110;

[0056] like Fig. 9As shown, in this embodiment, the driving mechanism includes a driving rod 850 arranged along the length direction of the installation cavity 910, the axial direction of the driving rod 850 is perpendicular to the axial direction of the first rotating rod 820, and the end of the first rotating rod 820 located in the installation cavity 910 is provided with a first bevel gear 920, and the driving rod 850 is provided with a plurality of second bevel gears 930 along the axial direction for meshing with the corresponding first bevel gears 920; the end of the driving rod 850 extending out of the installation box 810 is provided with a pulley 860, and the pulley 860 is used to connect to the power component.

[0057] Through the above-mentioned structure, a power component such as a motor is connected to the pulley 860 through a belt to rotate the driving rod 850 in the installation cavity 910, so that the corresponding second bevel gear 930 can drive the corresponding first bevel gear 920 to rotate, thereby better realizing the rotation of the first rotating rod 820; through the reasonable arrangement of the second bevel gear 930 at the driving rod 850, and the opposite rotation directions of adjacent first rotating rods 820 in the same installation cavity 910, it is possible to better adjust the posture of the wolfberries in the screening slot 110 in a more disordered state, thereby better facilitating the screening of the wolfberries.

[0058] like Figure 6 , 8 As shown in FIG. 9 , in this embodiment, a second rotating rod 870 with one end extending out of the bottom wall of the mounting cavity 910 is respectively provided on both sides of the inner wall of the mounting cavity 910 in the length direction, and one end of the second rotating rod 870 extending out of the mounting cavity 910 extends to the bottom wall of the sieve slot 110; a matching portion 220 is formed at the corresponding portion of the bottom wall of the sieve slot 110, and an elliptical matching cavity 230 is formed at the matching portion 220, and one end of the second rotating rod 870 extends into the matching cavity 230 and is provided with a curved rod 880;

[0061] In this embodiment, when the driving rod 850 rotates in the installation cavity 910 under the action of the power component, the curved rod 880 at the second rotating rod 870 can reciprocate against the inner wall of the matching cavity 230, and cooperate with the compression springs 610 and linear bearings on both sides of the screen slot 110, so that the screen slot 110 can be better rocked back and forth in the horizontal direction, thereby better accelerating the speed of the wolfberry rolling on the bottom wall of the screen slot 110, avoiding the wolfberry from blocking the screen hole 120, and cooperating with the posture adjustment component 140 to achieve the posture adjustment of the wolfberry to be screened in a more disordered rolling state at the bottom wall of the screen slot 110.
