Description

Technical Field

[0001] The utility model relates to the technical field of nut screening, in particular to a nut green skin screening device. Background Art

[0002] Before removing the peel of nuts, they need to be screened to meet production needs. The first choice is to screen out the empty nuts and the debris mixed in during picking.

[0003] Reference is made to the utility model patent with the authorized patent number CN219187265U, which discloses a nut green skin screening device, including a screening box, a connecting pipe is fixedly connected to the inside of the screening box, a notch is horizontally opened just above the connecting pipe, a spiral rod is movably connected to the inside of the connecting pipe, and a guide plate is fixedly connected to the inside of the screening box, and the cross-section of the guide plate is triangular. Servo motor 2 is started to drive the transmission wheel to rotate synchronously, and the screening rod is rotated under the action of the belt, and the empty shell nuts are picked up by the long thorns on the outside of the screening rod, so that the empty shell nuts overcome the obstruction of the baffle and move to just above the guide plate, so that the empty shell nuts and impurities are all concentrated just above the guide plate, which is conducive to the staff to uniformly salvage them and avoid fishing out solid nuts, thereby improving the screening efficiency of the staff.

[0004] During use, it was found that the above patent uses a salt water soaking and separation method to separate empty nuts and impurities in nuts. The density adjustment space of salt water has certain limitations. Its relative density is greater than that of pure water. It is difficult to achieve a high separation effect for nuts of different qualities. Its applicability is general. At the same time, some internal components of the patent are soaked in salt water, which is prone to rust and its service life is difficult to guarantee. For this reason, we proposed a nut green skin screening equipment to solve the above defects. Utility Model Content

[0005] The utility model aims to solve the shortcomings of the prior art and proposes a nut green peel screening device.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A nut green peel screening device comprises a screening chamber, a support frame is arranged below the screening chamber, a solid fruit outlet is installed at the lower port of the screening chamber, a cone bucket is installed at the upper port of the screening chamber, a side plate is installed on the left side of the cone bucket, a vibrator is installed at the bottom of the side plate, two air inlets are arranged below the vibrator, the air inlets are opened on the side wall of the screening chamber, a side box is installed on the right side of the screening chamber, an air outlet is arranged on the right side of the side box and an empty fruit outlet is arranged at the bottom of the side box, an inner plate is fixedly installed at the bottom of the cone bucket, an electric telescopic rod and a slide plate are arranged at the bottom of the inner plate, a casing is installed on the inner side of the air inlet, a fan is arranged inside the casing, a number of connecting rods are fixedly connected between the inner wall of the casing and the side wall of the fan, and a through opening is opened between the side wall of the screening chamber and the side box.

[0008] Preferably, a controller is installed on the front side of the screening chamber.

[0009] Preferably, two inner plates are symmetrically arranged along the inner side of the cone bucket, and the top surface of the inner plate is designed to be a gentle slope.

[0010] Preferably, the air outlet is formed by circular holes evenly distributed on the side wall of the side box.

[0011] Preferably, a filter is installed inside the air inlet.

[0012] Preferably, the electric telescopic rod is fixedly mounted on the inner wall of the screening chamber and two groups of the electric telescopic rod are symmetrically arranged along the bottom of the slide plate.

[0013] Preferably, the slide plate is fixedly connected to the output end of the electric telescopic rod, two slots are provided at the bottom of the inner plate, and a protrusion is fixedly installed on the upper side of the slide plate corresponding to the slot position, and the protrusion is slidably engaged with the inner side of the slot.

[0014] In the utility model, a nut green skin screening device is described, by arranging two groups of fans inside the screening chamber, starting the fans to blow air to the through opening, when nuts fall from the bottom opening of the cone bucket, under the action of wind pressure, the empty shelled nuts and impurities mixed in the nuts will be blown to the right side of the through opening, and then enter the side box, and then slide through the empty fruit outlet arranged at the bottom of the side box. At the same time, due to the large density of solid nuts, their falling trajectory will be slightly inclined to the right under the action of wind pressure, and finally slide from the inner wall of the screening chamber to the solid fruit outlet, and slide through the solid fruit outlet to complete the nut screening work. In this process, the screening is carried out by the action of wind pressure, and the wind pressure can be accurately controlled by controlling the rotation speed of the fan, so that the adjustment range of the wind pressure to the nuts is accurate and wide, which is suitable for the screening of different types of nuts and improves the applicability. In addition, the wind pressure screening method is adopted to keep the components inside the screening chamber dry, thereby improving the service life of the components.

[0015] In the utility model, a nut green skin screening device is described, with a slide plate slidingly arranged at the bottom of the inner plate, and the size of the gap between the slide plates on both sides can be adjusted by an electric telescopic rod, so as to adapt to the screening of nuts with different particle sizes. The gap of the slide plate is adjusted to be slightly larger than the particle size of the nuts to be screened, so that the nuts passing through the gap of the slide plate fall in a single layer, avoiding the effect of multiple layers of barriers caused by the nuts when falling, and further avoiding the effect of wind pressure after weakening some nuts, resulting in incomplete screening. The above arrangement improves the screening accuracy of the utility model.

[0016] The utility model has a reasonable design and utilizes the effect of wind pressure for screening. The wind pressure can be accurately controlled by controlling the rotation speed of the fan, so that the adjustment range of the wind pressure to the nuts is accurate and wide, which is suitable for the screening of different kinds of nuts and improves the applicability. In addition, the wind pressure screening method is adopted to keep the components inside the screening chamber dry, thereby improving the service life of the components.

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Reference Figure 1-4A nut green peel screening device comprises a screening chamber 1, a support frame is arranged below the screening chamber 1, a fruit outlet 3 is arranged at the lower port of the screening chamber 1, a cone bucket 4 is arranged at the upper port of the screening chamber 1, a side plate 5 is arranged on the left side of the cone bucket 4, a vibrator 6 is arranged at the bottom of the side plate 5, two air inlets 11 are arranged below the vibrator 6, the air inlet 11 is opened on the side wall of the screening chamber 1, a side box 8 is arranged on the right side of the screening chamber 1, an air outlet 9 is arranged on the right side of the side box 8, and an empty fruit outlet 10 is arranged at the bottom of the side box 8, and the air outlet 9 is provided by The side box 8 is formed by evenly distributed circular holes on the side wall, an inner plate 7 is fixedly installed at the bottom of the cone bucket 4, an electric telescopic rod 13 and a slide plate 14 are arranged at the bottom of the inner plate 7, the electric telescopic rod 13 is fixedly installed on the inner wall of the screening chamber 1 and two groups of electric telescopic rods 13 are symmetrically arranged along the bottom of the slide plate 14, a protective tube 15 is installed on the inner side of the air inlet 11, a fan 17 is arranged on the inner side of the protective tube 15, a number of connecting rods 16 are fixedly connected between the inner wall of the protective tube 15 and the side wall of the fan 17, and a through opening 18 is opened between the side wall of the screening chamber 1 and the side box 8.

[0024] In this embodiment, a controller 2 is installed on the front side of the screening chamber 1 .

[0025] Through the above structure, the controller 2 can be used to control the output power of the fan 17, and then the rotation speed of the fan 17 can be adjusted to achieve accurate control of the output wind pressure of the fan 17.

[0026] In this embodiment, two inner plates 7 are symmetrically arranged along the inner side of the cone bucket 4, and the top surface of the inner plate 7 is designed to be gently sloped.

[0027] Through the above structure, the gentle slope design of the top surface of the inner plate 7 allows the nuts to fall onto the inner plate 7 when they are put into the cone bucket 4. Under the action of the vibrator 6, the nuts will slowly slide into the gap in the middle of the inner plate 7 as the inner plate 7 slides, and then enter the upper side of the slide plate 14.

[0028] In this embodiment, a filter screen 12 is installed inside the air inlet 11 .

[0029] Through the above structure, the filter screen 12 installed inside the air inlet 11 prevents the flying of debris during the wind pressure screening, so that the screening work inside the screening chamber 1 is kept relatively stable.

[0030] In this embodiment, the slide plate 14 is fixedly connected to the output end of the electric telescopic rod 13, two slots 71 are provided at the bottom of the inner plate 7, and a protrusion 141 is fixedly installed on the upper side of the slide plate 14 corresponding to the slot 71, and the protrusion 141 is slidably engaged with the inner side of the slot 71.

[0031] Through the above structure, the slide plate 14 maintains a sliding connection with the inner plate 7 through the protrusion 141. When the electric telescopic rod 13 drives the slide plate 14 to slide, the sliding matching design of the protrusion 141 makes the slide plate 14 more stable when sliding.

[0032] In the utility model, when in use, according to the type of nuts to be screened, the wind pressure output value suitable for the nuts is output in the controller 2, and the electric telescopic rod 13 is started to drive the slide plate 14 to slide, and the distance between the gaps between the slide plates 14 on both sides is adjusted to be slightly larger than the outer particle size of the nuts, and corresponding collection containers are arranged at the bottom of the solid fruit outlet 3 and the empty fruit outlet 10. At this time, the preparation work before the use of the device is completed, and then the device is started through the controller 2, and the nuts to be screened are put into the cone bucket 4, and the nuts fall onto the inner plate 7 along with the cone bucket 4. Under the action of the vibrator 6, the nuts will slowly slide to the gap in the middle of the inner plate 7 along with the slope of the inner plate 7, and then enter the upper side of the slide plate 14. In the gap, since the gap adjustment rate of the slide plate 14 is larger than the outer particle size of the nuts to be screened, the nuts passing through the slide plate 14 fall in a single layer. When falling, the nuts are all affected by the wind pressure blown out by the left fan 17. The empty shelled nuts and impurities mixed in the nuts will be blown to the right side of the through opening 18 due to their relatively small density, and then enter the side box 8, and then slide into the collection container through the empty fruit outlet 10 set at the bottom of the side box 8. At the same time, the solid nuts have a large density, and their falling trajectory will be slightly inclined to the right under the action of wind pressure, and finally slide from the inner wall of the screening chamber 1 to the solid fruit outlet 3, and slide into the collection container through the solid fruit outlet 3, completing the nut screening work.
