Description

Technical Field

[0001] This invention relates to the field of bamboo shoot production technology, and in particular to a device for preserving bamboo shoots with shells to prevent them from becoming woody. Background Technology

[0002] Lignification of bamboo shoots refers to the process by which bamboo shoots gradually transform from tender shoots into woody ones during their growth. Under normal circumstances, the interior of bamboo shoots is mainly composed of fibrous tissue and cells. However, as bamboo shoots grow and develop, the shoot walls gradually thicken, the fibrous tissue increases, the water content decreases, and the shoot walls become harder and more fibrous, eventually forming solid, woody bamboo nodes. To prevent bamboo shoot lignification, preservation measures are generally taken to keep bamboo shoots in a moist environment, thus inhibiting lignification. When using chemical methods to maintain the freshness of bamboo shoots, direct soaking is usually the method, lacking intuitive and effective auxiliary measures. This results in the bamboo shoots being constantly soaked in the coating agent, which reduces the effectiveness of the anti-lignification treatment.

[0003] Therefore, in order to address the above problems, we are now developing a device for preserving bamboo shoots with shells that can automatically perform reciprocating soaking, improve the soaking effect, make the soaking more thorough, and prevent the bamboo shoots from becoming woody. Summary of the Invention

[0004] To overcome the shortcomings of existing devices that use chemical methods to maintain the freshness of bamboo shoots and lack intuitive and effective auxiliary measures, which leads to a reduction in the anti-lignification effect of bamboo shoots, this invention provides a bamboo shoot preservation device with shells that can automatically perform reciprocating soaking treatment, improve the soaking effect, and make the soaking more thorough, thus preventing the bamboo shoots from lignifying.

[0008] Optionally, it also includes a buffer mechanism, which includes a second spring, a connecting plate, and a contact element. At least four second springs are connected to the right wall of the placement seat, and a connecting plate is connected between the left sides of adjacent second springs. A contact element that contacts the placement plate is connected to the left side of the connecting plate.

[0009] Optionally, it also includes a filtration mechanism, which includes a connector, a rotating frame, a filter screen, and a third spring.

[0013] The present invention has the following advantages: 1.

[0015] 3. The present invention drives the output shaft to rotate through the second drive component, thereby causing the spur gear to drive the rack to move upward, which in turn allows the partition to automatically lift and open, allowing the placement plate to slide to the right for spraying.

Detailed Implementation

[0028] References to embodiments herein mean that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0029] A device for preserving bamboo shoots in their shells to prevent lignification, such as Figures 1-3 As shown, the system includes a support frame 1, a preservation frame 2, a water valve 21, a door panel 3, a spray assembly 4, and a soaking mechanism 5. There are five support frames 1. The top of the support frames 1 is connected to the preservation frames 2 for preserving bamboo shoots with shells. The right side of the preservation frame 2 is inclined. The lower right side of the preservation frame 2 is connected to a water valve 21 for drainage. The left and right sides of the preservation frame 2 are rotatably connected to door panels 3 for blocking and sealing. The upper right side of the preservation frame 2 is bolted to a spray assembly 4 for spraying and moisturizing bamboo shoots with shells. The spray assembly 4 includes a water pump, a connecting pipe, and a spray head. The upper right side of the preservation frame 2 is bolted to a water pump. A connecting pipe is connected between the water pump and the preservation frame 2. A spray head is connected to the connecting pipe. The right side of the preservation frame 2 is equipped with a soaking mechanism 5 for automatically soaking bamboo shoots with shells.

[0030] It should be noted that when preserving bamboo shoots with shells, it is necessary to protect them from lignification. This device can be used for this purpose. First, open the left door panel 3, then place the bamboo shoots with shells on the soaking mechanism 5. After placement, close the mechanism and start the soaking mechanism 5 to soak the bamboo shoots in the coating agent for preservation, thereby improving their resistance to lignification. After soaking, control the movement of the soaking mechanism 5 to transport the soaked bamboo shoots to the right along the preservation frame 2. Once the bamboo shoots are on the right side of the preservation frame 2, the spraying component 4 is activated at regular intervals to spray the bamboo shoots, improving their moisture content and further preventing lignification. The sprayed water will flow to the right through the inclined surface on the right side of the preservation frame 2 and eventually collect on the right side of the preservation frame 2. Then, close the spraying component 4 and open the water valve 21 to drain the water. Finally, open the right door panel 3 to remove the processed bamboo shoots.

[0031] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the soaking mechanism 5 includes a first drive assembly 51, a lead screw 52, ​​a liquid storage frame 53, a first guide rod 54, a first sliding plate 55, a rotating plate 56, and a placement plate 57. The lead screw 52 is rotatably connected to the left side of the preservation frame 2, and the upper part of the lead screw 52 passes through the preservation frame 2. The first drive assembly 51 is bolted to the upper left side of the preservation frame 2. The first drive assembly 51 is meshed with the top of the lead screw 52 through a bevel gear set. The liquid storage frame 53 for storing and placing the coating agent is connected to the left side of the preservation frame 2. The first guide rod 54 is connected to both the front and rear sides of the right side of the liquid storage frame 53. The rotating plate 56 is slidably connected between the first guide rods 54. The first sliding plate 55 is threadedly connected to the lower part of the lead screw 52. The first sliding plate 55 is rotatably connected to the rotating plate 56. The placement plate 57 for separating and placing bamboo shoots is placed on the rotating plate 56.

[0032] It should be noted that when preserving bamboo shoots, they must first be placed in batches on the placement plate 57. Then, the first drive assembly 51 is activated, which drives the lead screw 52 to rotate. This causes the first sliding plate 55 to slide up and down along the first guide rod 54, thus moving the placement plate 57 and the bamboo shoots up and down within the liquid storage frame 53. This method ensures that the coating agent in the liquid storage frame 53 fully contacts and reacts with the bamboo shoots, improving the preservation effect. After the preservation process is complete, the first drive assembly 51 is controlled to rotate the lead screw 52, ​​causing the first sliding plate 55 to slide upwards along the rotating plate 56, disengaging the rotating plate 56 from the first guide rod 54. At this point, the bamboo shoots, under their own weight, flip downwards. Finally, the first drive assembly is turned off. 51. As the rotating plate 56 tilts, the placement plate 57 slides to the right along the inclined surface of the rotating plate 56, thus automatically entering the right side of the preservation frame 2 for spraying treatment. Finally, the first drive component 51 is controlled to make the first sliding plate 55 drive the rotating plate 56 to move downwards and reset, so that the rotating plate 56 is re-slidably connected to the first guide rod 54. In summary, by driving the lead screw 52 to rotate through the first drive component 51, the first sliding plate 55 drives the rotating plate 56, causing the placement plate 57 to move up and down, so that the bamboo shoots can be fully soaked in the coating agent, making the soaking more uniform and thorough, and improving the preservation effect. After the treatment is completed, the first drive component 51 is controlled to move, so that the first sliding plate 55 drives the rotating plate 56 to move upwards, and then the placement plate 57 can automatically slide to the right to discharge the material, improving the convenience of operation.

[0033] like Figure 1 , Figure 2 and Figure 6 As shown, it also includes a placement mechanism 6, which includes a second drive assembly 61, a first pulley assembly 62, a second guide rod 63, a second sliding plate 64, and a placement seat 65. The second drive assembly 61 is bolted to the upper right side of the preservation frame 2. The second drive assembly 61 passes through the right wall of the preservation frame 2. The first pulley assembly 62 is connected between the second drive assembly 61 and the inner right wall of the preservation frame 2. The second guide rod 63 is connected to the inner right side of the preservation frame 2. Two second sliding plates 64 are slidably connected to the second guide rod 63. The second sliding plates 64 are all connected to the first pulley assembly 62. The left side of each of the second sliding plates 64 is connected to a placement seat 65 for engaging and driving the placement plate 57.

[0034] It should be noted that after the bamboo shoots have finished soaking in the coating agent, as the placement plate 57 automatically slides to the right to discharge the material, the placement plate 57 will continuously slide to the right along the right side of the preservation frame 2. Initially, the placement seat 65 is located near the bottom of the preservation frame 2, and the upper placement seat 65 is not flush with the inclined surface. At this time, before the placement plate 57 discharges the material, the second drive assembly 61 needs to be controlled so that the first pulley assembly 62 drives the second sliding plate 64 to slide upward along the second guide rod 63, thereby causing the second sliding plate 64 to drive the placement seat 65 to move upward, so that the upper placement seat 65 is flush with the inclined surface. When the placement plate 57 slides to the right, it will engage with the upper placement seat 65. After that, the second drive assembly 61 is activated again. The driving component 61 causes the first pulley assembly 62 to continue driving the second sliding plate 64, thereby causing the upper placement seat 65 to continue moving upwards and the lower placement seat 65 to be flush with the inclined surface. Then, the bamboo shoots can be placed on another placement plate 57 for preservation treatment, achieving the effect of preserving two groups of bamboo shoots and improving the preservation treatment efficiency. In summary, by driving the first pulley assembly 62 to rotate through the second driving component 61, the second sliding plate 64 can drive the placement seat 65 to slide, so that the placement seat 65 can engage with the placement plate 57, thereby causing the placement plate 57 to be lifted upwards under the drive of the placement seat 65, thus enabling the simultaneous preservation treatment of two groups of bamboo shoots and improving the preservation treatment efficiency.

[0035] like Figure 1 , Figure 2 , Figure 7 and Figure 8 As shown, it also includes a blocking mechanism 7, which includes a partition 71, a third guide rod 72, a rack 73, a moving frame 74, a first spring 75, a spur gear 76, a second pulley assembly 77, an output shaft 78, and a trigger 79. The partition 71 for separation is slidably connected to the middle of the preservation frame 2. The third guide rod 72 is connected to the rear side of the partition 71. The moving frame 74 is connected to the third guide rod 72. The rack 73 is slidably connected to the rear side of the moving frame 74. Two first springs 75 are connected between the rack 73 and the moving frame 74. The first springs 75 are both wound around the adjacent rack 73. The output shaft 78 is rotatably connected to the rear right side of the preservation frame 2. The spur gear 76 that meshes with the rack 73 is connected to the left side of the output shaft 78. The trigger 79 for triggering and pushing the rack 73 is connected to the left side of the spur gear 76. The second pulley assembly 77 is connected between the output shaft 78 and the second drive assembly 61.

[0036] It should be noted that as the second drive assembly 61 operates, the second pulley assembly 77 drives the output shaft 78 to rotate, which in turn causes the spur gear 76 to drive the trigger 79 to rotate. This, in turn, causes the rack 73 to drive the moving frame 74 to move upward. As the moving frame 74 moves upward, the partition 71 slides upward along the preservation frame 2 and opens, no longer obstructing the interior of the preservation frame 2. This allows the placement plate 57 to slide to the right along the preservation frame 2 to discharge material. It should be particularly noted that after the spur gear 76 rotates one revolution, the trigger 79 will also rotate one revolution and contact the rack 73 again, pushing the rack 73 forward. This causes the first spring 75 to be compressed, and the rack 73 no longer meshes with the spur gear 76. At this time, under the action of its own gravity, the partition 71 will move downward. The slide resets the food storage container 2, separating it again. During the downward sliding reset of the partition 71, the rack 73 disengages from the trigger 79. After disengagement, the rack 73 slides back and re-engages with the spur gear 76 under the action of the first spring 75. In summary, the second drive assembly 61 drives the output shaft 78 to rotate, causing the spur gear 76 to drive the rack 73 upward, thereby automatically lifting and opening the partition 71, allowing the placement plate 57 to slide to the right for spraying. After processing, the trigger 79 pushes the rack 73, disengaging it from the spur gear 76, thus automatically resetting the partition 71 and preventing water splashing and diluting the coating agent during spraying.

[0037] like Figure 2 and Figure 9 As shown, it also includes a buffer mechanism 8, which includes a second spring 81, a connecting plate 82 and a contact member 83. At least four second springs 81 are connected to the right wall of the placement seat 65. A connecting plate 82 is connected between the left sides of adjacent second springs 81. A contact member 83 that contacts the placement plate 57 is connected to the left side of the connecting plate 82.

[0038] It should be noted that when the placement plate 57 automatically slides to the right to discharge material, as the placement plate 57 engages with the placement seat 65, the contact member 83 will contact the right side of the placement plate 57. Thus, under the push of the placement plate 57, the contact member 83 causes the connecting plate 82 to slide to the right, thereby causing the second spring 81 to be compressed, which buffers the placement plate 57 and prevents the placement plate 57 from directly contacting the placement seat 65 and causing damage.

[0039] like Figure 5 and Figure 10As shown, it also includes a filter mechanism 9, which includes a connector 91, a rotating frame 92, a filter screen 93, and a third spring 94. The lower part of the lead screw 52 is slidably connected to the connector 91, and the right side of the connector 91 is rotatably connected to the rotating frame 92. The rotating frame 92 is connected to the filter screen 93 for filtering and blocking impurities. Two third springs 94 for buffering are connected between the rotating frame 92 and the liquid storage frame 53.

[0040] It should be noted that when soaking bamboo shoots, in order to prevent impurities on the bamboo shoots from falling into the coating agent and causing pollution, the impurities are filtered and blocked by the filter screen 93. When it is necessary to clean the impurities, the rotating frame 92 is rotated forward to open, so that the filter screen 93 can move synchronously, which makes it easier for the operator to clean the filter screen 93.

[0041] like Figure 2 and Figure 11 As shown, it also includes a blower mechanism 10, which includes a mounting frame 101, a fan 102 and a protective frame 103. The mounting frame 101 is connected to the top right side of the preservation frame 2. The fan 102 for air drying is rotatably connected inside the mounting frame 101. The protective frames 103 for protecting the fan 102 are connected to the lower left and right sides of the mounting frame 101.

[0042] It should be noted that after the spraying treatment is completed, in order to avoid the bamboo shoots being damaged by a large amount of water adhering to them, the fan 102 can be turned on to generate airflow to dry the bamboo shoots. After the treatment is completed, the fan 102 can be turned off.

[0043] Those skilled in the art should understand that the above embodiments do not limit the present invention in any way, and all technical solutions obtained by equivalent substitution or equivalent transformation fall within the protection scope of the present invention.
