Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of drying device, in particular to a blueberry fruit dry turning device. BACKGROUND

[0002] The blueberry fruit dry is made of fresh blueberries as raw materials, and is concentrated fruit dry after low-temperature drying; In the processing of fruit dry, fresh spherical blueberries are first laid flat on the drying tray, and then the stacked drying tray is transported to the drying box for drying. In this process, the following problems will occur: 1. When the fresh blueberries are placed on the drying tray, manual spreading is required, and the stacked blueberries need to be manually spread to ensure that each blueberry can efficiently lose moisture during subsequent drying. Manual turning has high labor intensity, low efficiency, and is prone to cause fruit dry skin rupture due to uneven force; 2. After the drying tray is pushed into the drying box, the water content gradient difference between the upper and lower sides of the blueberries is large during static drying of the multi-layer drying tray. Manual turning is required multiple times to extract the tray, resulting in large heat loss. Not only does this reduce the drying efficiency, but the remaining dried parts are also prone to nutrient loss due to over-baking, reducing the quality of the fruit dry.

[0003] Therefore, the present application provides a blueberry fruit dry turning device. SUMMARY

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0018] like Figures 1-7 As shown, an embodiment of the present invention provides a blueberry drying mixing device, comprising: The movable frame 1 has a rectangular support frame 101 connected to its upper end. Multiple positioning frames 2 are fitted onto the support frame 101 and are connected to each other. There are at least two positioning frames 2. The movable frame 1 can be connected to multiple positioning frames 2 through the support frame 101 to form a stacked structure. The support frame 101 is the bottom layer, and one of the positioning frames 2 is the top layer. The carrying tray 3 includes multiple moving rods 301 that slide horizontally through the positioning frame 2. The multiple moving rods 301 are arrayed along the width direction of the positioning frame 2 and their ends are fixedly connected to a pusher plate 302 located outside the positioning frame 2. The length of the moving rods 301 is greater than the length of the positioning frame 2. The moving rods 301 on two adjacent positioning frames 2 are arranged with opposite protruding directions. Each positioning frame 2 is provided with a carrying tray 3. The moving rods 301 in the carrying tray 3 are used to receive blueberries. The strip gaps between the moving rods 301 can not only receive blueberries, but also sort the blueberries by size. When blueberries need to be placed in the carrying tray 3, the sliding plate 302 can be pulled out to drive the multiple moving rods 301 to move back and forth synchronously. During this process, not only can loose blueberries be sorted out, but smaller blueberries can also be removed to ensure the uniformity of blueberry size, which is conducive to uniform drying time and ensures the quality of dried fruit. Multiple actuating discs 4 are positioned above the support discs 3. Each actuating disc includes two parallel connecting rods 401. The connecting rods 401 are detachably sleeved onto multiple movable rods 301 located on the same horizontal plane and positioned perpendicular to them. Multiple U-shaped elastic levers 402 connect the two connecting rods 401. The convex surfaces of the elastic levers 402 face downwards and are positioned between each pair of movable rods 301. It should be noted that each support disc 3 has one actuating disc 4, meaning that multiple movable rods 301 are equipped with two parallel connecting rods 401, and multiple elastic levers 402 connect the two connecting rods 301. The elastic lever 402 corresponds to the gap between the two moving rods 301 in the lower support plate 3. When the positioning frames 2 are stacked together, the blueberries on the support plate 3 will be resisted by the elastic lever 402 in the upper actuation plate 4. The blueberries are held in the middle by the moving rods 301 and the elastic lever 402. The moving rods 301 in adjacent layers protrude in opposite directions. The support plates 3 in different layers need to move alternately, thereby driving the elastic lever 402 connected to it to move horizontally relative to the support plate 3 of the lower layer, thereby causing the blueberries held in them to roll, realizing the blueberry flipping operation. The staggered pushing component 5 comprises multiple bearing plates 3 staggered protruding, with collars 501 connected to the pushing cross plates 302 at the protruding ends. Telescopic vertical tubes 502 are inserted between the collars 501 on the same side. A reciprocating pushing component 503 for driving relative movement is connected between the bottoms of two telescopic vertical tubes 502. A telescopic mounting plate 504 is connected between the tops of two telescopic vertical tubes 502, with one actuating disc 4 connected to the telescopic mounting plate 504. The ends of the bearing plates 3 protruding in the same direction are connected together by the collars 501 using the telescopic vertical tubes 502. When the telescopic vertical tubes 502 move, they drive all the bearing plates 3 to move together. Therefore, the reciprocating pushing component 503 can... The device drives two telescopic vertical tubes 502 to move relative to each other, and at the same time drives multiple carrier plates 3 to move horizontally in an alternating manner. When the carrier plates 3 move horizontally in an alternating manner, they can also drive the actuating plates 4 connected to them to move in an alternating manner. The actuating plates 4 are installed on the carrier plates 3 through connecting rods 401. Therefore, the actuating plates 4 move in an alternating manner with the carrier plates 3 and the lower carrier plates 3, realizing the automatic turning operation of blueberries. There is no need to manually remove the device from the dryer. It can be operated automatically directly inside the dryer, saving a lot of manpower and time, while also avoiding heat loss and ensuring drying efficiency. At the same time, the automatic turning operation also ensures that the rate of moisture loss in different parts of the blueberries is uniform, ensuring the quality of dried fruit. This device has two working states. The first is when blueberries are laid in the support tray 3. The blueberries are simply poured in, and then the horizontal plate 302 is pulled and pushed, causing the blueberries to automatically roll and fall between the moving rods 301. This eliminates the need for manual manipulation, saving manpower and avoiding the risk of blueberries breaking due to manual manipulation. The second state is in the dryer. Multiple positioning frames 2 are stacked on the support frame 101. After drying for a certain period, the reciprocating pusher 503 drives the two telescopic vertical tubes 502 to move relative to each other, causing the support trays 3 to move alternately. As the support trays 3 move alternately, the actuating plates 4 installed on them move together, creating an alternating movement with the lower support trays 3. This causes the blueberries sandwiched between them to roll, completing the flipping operation. There is no need to manually remove the blueberries from the drying equipment, preventing heat loss and ensuring drying efficiency and quality.

[0019] like Figure 2 As shown, the specific structure of the movable frame 1 of the present invention is disclosed. The movable frame 1 includes a bottom frame 102 and a support frame 101 constructed on the upper end of the bottom frame 102. Universal wheels 103 are fixedly connected to the four corners of the bottom of the bottom frame 102. Two inclined sleeves 104 are fixedly connected to both sides of the bottom frame 102. U-shaped push rods 105 are inserted into the two sleeves 104. The universal wheels 103 and U-shaped push rods 105 are set at the bottom of the bottom frame 102, which can facilitate the overall movement of the device. The sleeves 104 can facilitate the removal of the U-shaped push rods 105, making it easy to push the device into the dryer and remove it, saving space and increasing the convenience of the device.

[0020] like Figures 1-3 As shown, the specific connection structure of the positioning frame 2 of the present invention is disclosed. The top of the positioning frame 2 is constructed with a vertical mesh frame 201, and the bottom of the positioning frame 2 is constructed with a stepped groove 202 for inserting the vertical mesh frame 201 and the support frame 101. Handles 203 are fixedly connected to both sides of the vertical mesh frame 201. The stepped groove 202 and the vertical mesh frame 201 are used to realize the positioning and stacking of multiple positioning frames 2, which can effectively limit the positioning frame 2, prevent it from sliding, and ensure stability. At the same time, the stepped groove 202 is connected by insertion, which also facilitates the subsequent disassembly operation and increases convenience.

[0021] like Figures 5-6The connection method between the connecting rod 401 and the moving rod 301 of the present invention is disclosed. The connecting rod 401 includes a horizontal connecting rod 4011 arranged perpendicular to the moving rod 301. The bottom of the horizontal connecting rod 4011 has a plurality of inner arc grooves 4012 arranged in an array along its length direction. Both ends of the inner arc grooves 4012 are provided with locking protrusions 4013. The moving rod 301 has an outer arc groove 4014 nested with the inner arc grooves 4012. The outer arc groove 4014 has a locking groove 4015 that engages with the locking protrusions 4013. When it is necessary to pour the blueberries into the carrying tray 3, the agitator 4 needs to be detached. After the blueberries are laid flat, the agitator 4 needs to be reinstalled. The inner arc groove 4012 is installed to facilitate automatic turning and mixing in the dryer. When the agitator plate 4 needs to be installed, simply press the connecting rod 401 toward the moving rod 301 so that the inner arc groove 4012 fits onto the outer arc groove 4014. The operation is simple and convenient. It should be noted that the arc angle of the inner arc groove 4012 is greater than 180 degrees, so it can be snapped onto the outer arc groove 4014 and also press against it. At the same time, the locking protrusion 4013 on the inner arc groove 4012 will first slide against the bottom of the outer arc groove 4014 and then lock against the locking groove 4015 to increase the stability of the connection, prevent it from easily falling off, and ensure the stability of subsequent movement.

[0022] like Figures 5-6 As shown, the upper structure of the connecting rod 401 of the present invention is disclosed. The top of the horizontal connecting rod 4011 is arrayed with a plurality of material-pushing posts 4016 located between each pair of moving rods 301. The material-pushing posts 4016 are made of rubber. By setting the material-pushing posts 4016 on the upper side of the horizontal connecting rod 4011, they can protrude from the upper surface of the moving rod 301 on the bearing plate 3 of this layer, and can be used to support the blueberries from the side. When the actuating plate 4 moves with the bearing plate 3 of this layer, it will drive all the blueberries between the two horizontal connecting rods 4011 to move together. The actuating plate 4 on the upper side of this layer will move alternately relative to this layer. The elastic lever 402 will abut against the blueberries in this layer to better perform the rolling operation.

[0023] like Figure 7The specific structure of the elastic lever 402 of the present invention is disclosed. The elastic lever 402 includes a plurality of rubber crossbars 4021 disposed between each pair of moving rods 301. Both ends of the rubber crossbars 4021 are constructed with inclined tubes 4022. The bottom of the horizontal connecting rod 4011 is constructed with a plurality of L-shaped inclined rods 4023 disposed vertically opposite to the material-pushing column 4016. The inclined tubes 4022 are slidably sleeved between two horizontally opposite L-shaped inclined rods 4023. It should be noted that the setting of the rubber crossbars 4021 can increase the friction on the surface of the blueberries, making it easier to drive the blueberries to roll. The L-shaped inclined rods 4023 and the inclined tubes 4022 are sleeved together. The elasticity of the rubber crossbars 4021 can realize the extension and retraction of the inclined tubes 4022 and the L-shaped inclined rods 4023, thereby changing the distance between the rubber crossbars 4021 and the lower moving rod 301, thus adapting to the clamping and resisting operation of blueberries of different sizes and increasing the flexibility of the device.

[0024] like Figure 7 As shown, the specific structure of the telescopic vertical tube 502 of the present invention is disclosed. The telescopic vertical tube 502 includes an outer cylinder 5021 inserted into a collar 501, a reciprocating pushing member 503 connected to the bottom end of the outer cylinder 5021, an inner tube 5022 slidably inserted into the outer cylinder 5021, a telescopic mounting plate 504 connected to the top end of the inner tube 5022, and a fixing bolt 5023 that abuts against the inner tube 5022 is threaded through the side of the outer cylinder 5021. Since there are multiple positioning frames 2, when it is necessary to add positioning frames 2 and bearing plates 3, additional collars 501 can be connected by extending the telescopic vertical tube 502 to achieve synchronous movement of the bearing plates 3 and the actuating plate 4. After increasing the number of positioning frames 2 and bearing plates 3, it is only necessary to extend the inner tube 5022 outward relative to the outer cylinder 5021 and then fix its position by fixing bolts 5023. The operation is simple and the convenience of the device is increased.

[0025] like Figures 7-8As shown, the present invention discloses a connection structure between the tops of two telescopic vertical tubes 502, which increases structural stability. The telescopic mounting plate 504 includes an extension plate 5041 fixedly connected to the tops of the two inner tubes 5022. One of the extension plates 5041 has a sleeve plate 5042 at its end for fitting the other extension plate 5041. Both the extension plate 5041 and the sleeve plate 5042 connected to it have two through holes 5043. A pusher post 4016 on one of the horizontal connecting rods 4011 is inserted into the through hole 5043. The upper end of the pusher post 4016 is tightly fitted with a rubber ring 5044 that abuts against the extension plate 5041 and the sleeve plate 5042. The telescopic mounting plate 504 is mainly used for connecting... The tops of the two telescopic vertical tubes 502 can move stably when they move synchronously relative to each other, reducing jamming and ensuring smooth pushing and rolling of blueberries. It should be noted that the length of the extension plate 5041 connected to the sleeve plate 5042 is greater than the length of the actuating plate 4. An additional actuating plate 4 can be installed through the perforation 5043 on it, so that the actuating plate 4 moves synchronously with the telescopic vertical tube 502 connected to the extension plate 5041, and the direction of movement is opposite to the direction of movement of the bearing plate 3 below it. Therefore, the blueberries clamped between them can also be actuated, causing the blueberries to roll, adding an extra layer of blueberry storage area, thereby increasing the amount of blueberries dried per unit time.

[0026] like Figure 2 The reciprocating pushing component 503 of the present invention is disclosed to realize the automated pushing and turning operation of blueberries. The reciprocating pushing component 503 includes a transmission gear 5031 rotatably installed in the middle of the bottom frame 102. Two toothed plates 5032 that mesh with the two sides of the transmission gear 5031 are slidably installed in the bottom frame 102. The opposite ends of the two toothed plates 5032 are each constructed with a post 5033 that inserts into the bottom of the outer cylinder 5021. A drive motor 5034 for driving the transmission gear 5031 to reciprocate is fixedly connected in the bottom frame 102. When the device is transported into the dryer, the drive motor 5034 can drive the transmission gear 5031 to move forward. The machine rotates in one direction and then in the opposite direction after a certain period of time. The rotation of the transmission gear 5031 will drive the toothed plates 5032 on both sides to mesh and drive simultaneously, thereby realizing the relative movement of the two toothed plates 5032 and the relative movement of the telescopic vertical tube 502. The telescopic vertical tube 502 will drive the carrier plate 3 connected to it to move synchronously. Therefore, the carrier plates 3 in the two adjacent layers will move alternately, that is, the moving plate 4 and the lower carrier plate 3 move alternately, thereby making the blueberries held between them roll, realizing the turning and mixing operation of blueberries. The machine operates automatically without human intervention, saving manpower. At the same time, there is no need to remove the blueberries from the dryer, thus improving drying efficiency.

[0027] like Figure 1As shown, the present invention discloses a device for assisting blueberry rolling. A vibration motor 6 is fixedly connected to the support frame 101. By installing the vibration motor 6 on the support frame 101, the vibration motor 6 can be turned on when blueberry rolling is required, so that the support frame 101 and the multiple positioning frames 2 connected thereto vibrate simultaneously, reducing the contact area between the blueberry and the carrier plate 3, facilitating its rolling and preventing sticking.

[0028] The above description of the disclosed embodiments enables those skilled in the art to make or use the invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
