Description

Technical Field

[0001] This utility model relates to the field of sea buckthorn production technology, specifically a local low-temperature sea buckthorn fruit removal and impurity removal machine. Background Technology

[0002] Sea buckthorn berries have thin skins, are small, and grow in clusters on branches, making them difficult to harvest directly. In production, the fruiting branches are often pruned, quickly frozen at low temperatures, and then the berries are separated from the branches by mechanical beating.

[0003] In existing production methods, to reduce the impact of environmental factors on frozen sea buckthorn branches and fruits, leading to berry rewarming, the fruit-removing machine and cleaning device are placed in a cooling workshop. The workshop environment temperature is -5 to -15℃, creating a harsh, low-temperature, and damp working environment. Furthermore, the high energy consumption of the workshop's cooling system increases the processing cost of sea buckthorn. Therefore, the development of a localized low-temperature sea buckthorn fruit-removing and impurity-removing machine that can reduce energy consumption, improve the working environment, and enhance processing efficiency is urgently needed. Utility Model Content

[0004] The present invention aims to overcome the defects of the prior art and provide a local low-temperature seabuckthorn fruit removal and impurity removal machine.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A localized low-temperature seabuckthorn fruit removal and impurity removal machine includes a transmission system, a feeding system, and a freezing and separation system. The transmission system includes a motor and an output shaft. The feeding system includes a feed inlet and a feed screw. A first sprocket is provided on the feed screw, and the output shaft and the first sprocket are connected by a first chain. The freezing and separation system includes an insulation chamber, a conveying channel located at the front end of the insulation chamber and connected to the feeding system, a coaxial double drum screen abutting against the conveying channel, a seabuckthorn fruit and branch outlet located at the rear end of the insulation chamber, a seabuckthorn fruit outlet located below the insulation chamber, and a condensation circulation pipeline surrounding the inner wall of the insulation chamber.

[0007] Specifically, the feeding screw conveys the seabuckthorn branches and fruits in the feed inlet through the conveying channel to the coaxial double drum screen, where they are frozen under the action of the condensation circulation pipeline. After separation, the seabuckthorn branches and fruits are output from the seabuckthorn branches outlet and the seabuckthorn fruits are output from the seabuckthorn fruits outlet.

[0008] Furthermore, the coaxial double drum screen includes an outer drum screen and an inner drum screen located inside the outer drum screen, and the outer drum screen and the inner drum screen are fixedly connected by a number of support rods provided at their respective front and / or rear ends.

[0009] Furthermore, a connecting plate is provided at the point where the conveying channel abuts the coaxial double drum screen, and several rollers are provided on both the connecting plate and the inner wall of the tail end of the insulation cavity; a screen fixing ring is provided at both the front and rear ends of the inner drum screen or the outer drum screen, wherein a screen tooth ring is provided next to the screen fixing ring at the front end; the screen fixing rings at the front and rear ends are tangentially engaged with several rollers on the connecting plate and the inner wall of the tail end of the insulation cavity, respectively, to achieve support of the coaxial double drum screen in the insulation cavity; the screen tooth ring meshes with a screen drive gear connected to a screen rotating shaft to achieve rotation of the coaxial double drum screen, and a second sprocket is provided on the screen rotating shaft, which is connected to the output shaft and the second sprocket by a second chain.

[0010] Specifically, the connecting plate and the inner wall of the insulation cavity's tail end preferably each have three rollers, evenly distributed on the end circumference of the coaxial double drum screen. More specifically, the screen shaft passes through the center of one of the rollers and is fixedly connected to the screen drive gear, ensuring both relative rotation and support between the roller and the coaxial double drum screen. Even more specifically, each roller on the connecting plate corresponds horizontally to one on the inner wall of the insulation cavity's tail end, keeping the central axis of the coaxial double drum screen parallel to the horizontal line, which facilitates stable support and rotation of the coaxial double drum screen.

[0011] Furthermore, the inner rotating screen is configured with three types of screen holes—large, medium, and small—from the front end to the rear end.

[0012] Specifically, preliminary production trials showed that the amount of fruit separated from branches decreased from the front to the back of the drum screen, while the amount of branches broken by impact increased in the middle and later sections of the drum screen. To address this, large-diameter screen holes were opened at the front of the drum screen to allow the separated berries to pass through quickly and fall through. Smaller-diameter holes were then opened in the middle and later sections to meet the screening requirements of frozen berries while reducing the screening of small branches and lowering the impurity content of the berries.

[0013] Furthermore, the insulation cavity is also provided with a refrigerant inlet and a refrigerant outlet that are respectively connected to both ends of the condensation circulation pipeline.

[0014] Furthermore, a seabuckthorn fruit conveying spiral is also included between the coaxial double drum screen and the seabuckthorn fruit outlet. The seabuckthorn fruit conveying spiral includes two counter-rotating spirals relative to both sides of the seabuckthorn fruit outlet, and the seabuckthorn fruit conveying spiral is directly connected to the output shaft.

[0015] Specifically, when the seabuckthorn fruit conveying spiral rotates, the two counter-rotating spirals can push the seabuckthorn fruits located on both sides of the seabuckthorn fruit outlet to the seabuckthorn fruit outlet.

[0016] Furthermore, a rotating main shaft is provided on the central axis of the inner drum screen, and a number of nail teeth are evenly distributed along two spiral lines spaced 180° apart on the rotating main shaft; a branch conveying spiral is provided on the outer surface of the inner drum screen; a third sprocket is provided on the rotating main shaft, and the output shaft and the third sprocket are connected by a third chain.

[0017] Specifically, when the rotating main shaft rotates, the several nail teeth can strike the frozen sea buckthorn branches and fruits axially conveyed inside the inner drum screen. At the same time, the frozen sea buckthorn branches and fruits are rubbed by the inner drum screen, causing the frozen sea buckthorn fruits to fall off the sea buckthorn branches under external force, thus completing the separation of sea buckthorn branches and fruits.

[0018] Furthermore, the feed screw has a hollow shaft and is loosely fitted onto a portion of the rotating main shaft via bearings.

[0019] Specifically, the rotating spindle can be divided into a first rotating spindle section and a second rotating spindle section, which are fixedly connected. The first rotating spindle section is located inside the insulation cavity, and the plurality of spike teeth are located on the first rotating spindle section. The second rotating spindle section extends out of the insulation cavity toward the feeding system, and the hollow shaft of the feeding screw is loosely fitted onto a portion of the second rotating spindle section through a bearing.

[0020] More specifically, the end of the first rotating spindle segment away from the second rotating spindle is fixed to the inner wall of the tail end of the insulation cavity by a bearing.

[0021] Furthermore, a flow damper is also provided on the first rotating main shaft section near the tail end of the insulation cavity.

[0022] Specifically, the flow-reducing plate has an inverted cone structure, which can increase the material removal time and improve the removal rate.

[0023] Furthermore, it also includes a frame for fixing the transmission system, feeding system and freezing separation system together.

[0024] Furthermore, the feeding system is connected to the freezing separation system on both sides, and the transmission system is located below the feeding system.

[0025] More specifically, the hollow shaft of the feeding screw and the second rotating main shaft section both extend out of the feeding system and are fixed to the frame by their respective bearings. The screen shaft and the sea buckthorn fruit conveying screw both pass through the insulation cavity by their respective bearings and are then fixed to the frame by their respective other bearings.

[0026] Furthermore, the conveying channel is funnel-shaped.

[0027] Specifically, the diameter of the funnel-shaped opening increases from the feeding screw towards the coaxial double drum screen, and the largest diameter is the same as and abuts against the inner diameter of the inner drum screen. This arrangement makes it easier for the sea buckthorn branches and fruits to be fed axially into the freezing and separation system via the feeding screw.

[0028] Compared with the prior art, this utility model has the following advantages:

[0029] This utility model of a localized low-temperature seabuckthorn fruit removal and impurity removal machine can effectively separate seabuckthorn branches and fruits, remove impurities, and reduce energy consumption during fruit removal. The localized low-temperature environment maintains a low temperature within a small processing space, keeping frozen seabuckthorn branches and fruits at a low temperature, facilitating branch-fruit separation during mechanical fruit removal and reducing damage to frozen berries. It also reduces refrigeration energy consumption during fruit removal, maintains a normal workshop temperature, and significantly improves the on-site working environment compared to the damp and cold environment of a low-temperature workshop.

Detailed Implementation

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0040] like Figure 1-7 As shown, a localized low-temperature seabuckthorn fruit removal and impurity removal machine includes a transmission system 1, a feeding system 2, and a freezing and separation system 3. The transmission system 1 includes a motor 1.1 and an output shaft 1.2. The feeding system 2 includes a feed inlet 2.1 and a feeding screw 2.2. A first sprocket 4.1 is provided on the feeding screw 2.2, and the output shaft 1.2 and the first sprocket 4.1 are connected by a first chain 5.1. The freezing and separation system 3 includes an insulation chamber, a conveying channel 3.1 located at the front end of the insulation chamber and communicating with the feeding system 2, a coaxial double drum screen 3.2 abutting against the conveying channel 3.1, a seabuckthorn fruit and branch outlet 3.3 located at the rear end of the insulation chamber, a seabuckthorn fruit outlet 3.4 located below the insulation chamber, and a condensation circulation pipeline 3.5 surrounding the inner wall of the insulation chamber.

[0041] In this embodiment, the coaxial double drum screen 3.2 includes an outer drum screen 3.6 and an inner drum screen 3.7 located inside the outer drum screen 3.6. The outer drum screen 3.6 and the inner drum screen 3.7 are fixedly connected by a plurality of support rods 7 provided at their respective front and rear ends.

[0042] In this embodiment, a connecting plate 3.8 is provided at the point where the conveying channel 3.1 abuts against the inner drum screen 3.7. Three rollers 3.9 are provided on both the connecting plate 3.8 and the inner wall of the insulation cavity. Screen fixing rings 3.10 are provided at both the front and rear ends of the inner drum screen 3.7. A screen toothed ring 3.11 is provided next to the screen fixing ring 3.10 at the front end. The screen fixing rings 3.10 at the front and rear ends are respectively connected to the connecting plate 3.8. The plate 3.8 and the roller 3.9 on the inner wall of the insulation cavity tail end are tangentially engaged to support the coaxial double drum screen 3.2 within the insulation cavity. The screen tooth ring 3.11 meshes with the screen drive gear 3.13 connected to the screen rotating shaft 3.12 to achieve rotation of the coaxial double drum screen 3.2. A second sprocket 4.2 is provided on the screen rotating shaft 3.12, which is connected to the output shaft 1.2 and the second sprocket 4.2 via a second chain 5.2. Specifically, the screen rotating shaft 3.12 passes through the center of one of the rollers 3.9 and is fixedly connected to the screen drive gear 3.13, which can simultaneously ensure the relative rotation and support between the roller 3.9 and the coaxial double drum screen 3.2. More specifically, each roller 3.9 on the connecting plate 3.8 corresponds one-to-one with the roller on the inner wall of the end of the insulation cavity in terms of horizontal height, so as to keep the central axis of the coaxial double drum screen 3.2 parallel to the horizontal line, which is beneficial to the stable support and rotation of the coaxial double drum screen 3.2.

[0043] With the above settings, the inner drum screen 3.7 and the outer drum screen 3.6 of the coaxial double drum screen 3.2 can rotate synchronously.

[0044] In this embodiment, the inner rotating screen 3.7 is configured with three types of screen holes from front to back: large screen hole 3.71, medium screen hole 3.72, and small screen hole 3.73.

[0045] In this embodiment, the insulation cavity is also provided with a refrigerant inlet 3.51 and a refrigerant outlet 3.52 that are respectively connected to both ends of the condensation circulation pipeline 3.5.

[0046] In this embodiment, a seabuckthorn fruit conveying screw 3.14 is further included between the outer drum screen 3.6 and the seabuckthorn fruit outlet 3.4. The seabuckthorn fruit conveying screw 3.14 includes two counter-rotating spiral sections relative to both sides of the seabuckthorn fruit outlet 3.4. The seabuckthorn fruit conveying screw 3.14 is directly connected to the output shaft 1.2 to achieve rotation. Specifically, when the seabuckthorn fruit conveying screw 3.14 rotates, the two counter-rotating spiral sections can push the seabuckthorn fruits located on both sides of the seabuckthorn fruit outlet 3.4 to the seabuckthorn fruit outlet 3.4.

[0047] In this embodiment, a rotating main shaft 3.15 is provided on the central axis of the inner drum screen 3.7, and a plurality of nail teeth 3.16 are evenly distributed along two spiral lines spaced 180° apart on the rotating main shaft 3.15; a branch conveying spiral 3.17 is provided on the outer surface of the inner drum screen 3.7; a third sprocket 4.3 is provided on the rotating main shaft 3.15, and the output shaft 1.2 and the third sprocket 5.3 are connected by a third chain 5.3.

[0048] In this embodiment, the rotating spindle 3.15 is divided into a first rotating spindle segment 3.151 and a second rotating spindle segment 3.152. The first rotating spindle segment 3.151 and the second rotating spindle segment 3.152 are fixedly connected. The first rotating spindle segment 3.151 is located inside the insulation cavity, and the plurality of spike teeth 3.16 are located on the first rotating spindle segment 3.151. The second rotating spindle segment 3.152 extends out of the insulation cavity toward the feeding system 2. The hollow shaft of the feeding screw 2.2 is loosely fitted onto a portion of the second rotating spindle segment 3.152 via bearings. The end of the first rotating spindle segment 3.151 away from the second rotating spindle segment 3.152 is fixed to the inner wall of the tail end of the insulation cavity via bearings.

[0049] In this embodiment, a flow damper 3.18 is also provided on the first rotating spindle segment 3.151 near the tail end of the insulation cavity.

[0050] In this embodiment, the flow damper 3.18 has an inverted cone structure.

[0051] In this embodiment, a frame 6 is also included, which is used to fix the transmission system 1, the feeding system 2, and the freezing separation system 3. The feeding system 1 is connected to the freezing separation system 2 from the left and right, and the transmission system 3 is located below the feeding system 2.

[0052] In this embodiment, the hollow shaft of the feeding screw 2.2 and the second rotating main shaft section 3.152 both extend out of the feeding system 1 and are fixed to the frame 6 by their respective bearings. The screen shaft 3.12 and the sea buckthorn fruit conveying screw 3.14 both pass through the insulation cavity by their respective bearings and are then fixed to the frame 6 by their respective other bearings.

[0053] In this embodiment, the conveying channel 3.1 is funnel-shaped.

[0054] Specifically, the diameter of the funnel-shaped opening increases from the feed screw 2.2 toward the inner drum screen 3.7, and the largest opening is the same size as and abuts against the inner diameter of the inner drum screen 3.7. This arrangement makes it easier for the sea buckthorn branches and fruits to be fed axially into the inner drum screen 3.7 by the feed screw 2.2.

[0055] In this embodiment, the localized low-temperature seabuckthorn fruit removal and impurity removal machine feeds seabuckthorn branches and fruits through the inlet 2.1. The feed screw 2.2 then conveys the fruit to the conveying channel 3.1, where it reaches the inner drum screen 3.7. Under the impact and friction of the spikes 3.16 and the inner drum screen 3.7, most of the berries and branches fall off. The branches move forward along the inner drum screen 3.7, while the berries fall directly into the seabuckthorn fruit conveying screw 3.14 through the large screen hole 3.71 at the front end of the inner drum screen 3.7. During the axial fruit removal process, the berries and branches continuously separate. The branches are pushed out of the seabuckthorn fruit and branch outlet 3.3 by the spirally distributed spikes 3.16. The frozen berries that fall through the two layers of screen holes fall onto the seabuckthorn fruit conveying screw 3.14, which pushes them axially to the seabuckthorn fruit outlet 3.4, where they are transported to the subsequent impurity removal and sorting device. After sorting, frozen berries meeting the impurity content requirements are obtained. Small branches and impurities that fall off the inner drum screen 3.7 are conveyed axially by the branch conveying screw 3.17 to the sea buckthorn fruit branch discharge port 3.3.

[0056] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
