Description

Technical Field

[0001] The present invention relates to the technical field of intelligent transportation of agricultural products, and in particular to blanching equipment with a protective function for chestnut processing. Background Art

[0002] Chestnut blanching is a key pretreatment step in the chestnut processing process. It mainly achieves the purposes of sterilization, enzyme inactivation, skin softening, and easy shelling through short-term high-temperature treatment (hot water or steam). During the chestnut blanching process, a conveying device is often required to transport the chestnuts.

[0003] The following deficiencies exist in the chestnut blanching and transportation process in the prior art: 1. Traditional conveying methods (such as chain belt or drum type) easily cause chestnut stacking, some chestnuts are covered, and insufficient heating results in poor blanching effect, local over-ripe or under-ripe phenomenon, affecting subsequent shelling and taste consistency; 2. Chestnuts have a low density and are easy to float in water, making it difficult to be completely immersed, resulting in insufficient blanching time, incomplete softening of the skin, and increased difficulty in shelling. Traditional conveying devices cannot effectively control the chestnuts, causing some chestnuts to stay for too long while others pass through quickly, resulting in significant differences in blanching time and unstable quality of the finished product; 3. Untimely cooling after blanching may cause accumulation of residual heat in the chestnuts, affecting subsequent packaging or freezing effects. Therefore, a blanching equipment with protective function for chestnut processing is proposed to solve the above-mentioned problems. Summary of the Invention

[0004] The purpose of the present invention is to solve the problems in the background technology and to propose a blanching device with a protective function for chestnut processing.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] The two gears are connected with each other through the outer wall of the gear train, and the two gears are connected with each other through the outer wall of the gear train, and the two gears are connected with each other through the outer wall of the gear train.

[0007] Preferably, the outer wall of the conveying frame is fixedly connected to the motor frame, the inner wall of the motor frame is fixedly connected to the conveying motor, the output shaft of the conveying motor is fixedly connected to the outer wall of one of the transmission wheels, and the outer wall of the conveying frame is fixedly connected to the blanking plate.

[0008] Preferably, the inner wall of the conveying frame is fixedly connected to a storage basket, and the outer wall of the storage basket is fixedly connected to a contact plate.

[0009] Preferably, the outer wall of the partition is fixedly connected to the second connecting plate, the outer wall of the second connecting plate is fixedly connected to the first spring, the end of the first spring away from the second connecting plate is fixedly connected to the first connecting plate, and the first connecting plate is fixedly connected to the outer wall of the partition.

[0010] Preferably, the outer walls of the two second slide rods are fixedly connected to the first slide rod, the outer wall of the fixing frame is fixedly connected to the fixing plate, and the first slide rod is slidably connected to the fixing plate through a telescopic slide groove.

[0011] Preferably, the inner wall of the partition is rotatably connected to two rotating shafts, the outer wall of the rotating shafts is fixedly connected to side limit plates, the two side limit plates are located between the two trapezoidal sliders, and two second springs are fixedly connected between the side limit plates and the partition.

[0012] Preferably, pressure blocks are fixedly connected to the outer walls on both sides of the main cover plate.

[0013] Preferably, a torsion spring is fixedly connected between the fixing frame and the main cover plate, and a second sliding groove is provided on the inner wall of the placeholder plate.

[0014] Compared with the existing technology, the present invention has the following beneficial effects:

[0015] The present invention uses partitions and spacers with adjustable spacing to dynamically control the capacity between the two partitions, ensuring uniform distribution of chestnuts and preventing stacking. When chestnuts pass under the storage basket, the partition spacing automatically decreases to ensure a single-layer arrangement. After moving out of the storage area, the spacing is restored to prevent stacking. The main cover and auxiliary cover use a permeable structure to cover the chestnuts, completely immersing them in water to prevent inadequate blanching due to buoyancy. After completion, the partitions naturally open with the curvature of the drive wheel, allowing the chestnuts to automatically roll off for easy subsequent processing. The present invention achieves automatic adjustment of the partition spacing solely through the linkage structure of the contact plate, pressure block, and displacement rod, without the need for any drive structure. After the partition spacing is restored, the chestnuts are more loosely distributed, promoting cooling uniformity, preventing excess heat accumulation, and improving the degree of production automation.

[0029] Reference Figures 1-10 A blanching equipment with a protective function for chestnut processing includes: a conveying frame 1, the inner wall of the conveying frame 1 is rotatably connected to two transmission wheels 7, the outer walls of the two transmission wheels 7 are provided with a conveying mesh belt 8, the outer wall of the conveying mesh belt 8 is fixedly connected to a plurality of partitions 11, the outer wall of the conveying frame 1 is fixedly connected to a motor frame 3, the inner wall of the motor frame 3 is fixedly connected to a conveying motor 4, the output shaft of the conveying motor 4 is fixedly connected to the outer wall of one of the transmission wheels 7, the outer wall of the conveying frame 1 is fixedly connected to a blanking plate 5, the inner wall of the conveying frame 1 is fixedly connected to a storage basket 2, and the outer wall of the storage basket 2 is fixedly connected to a contact plate 6.

[0030] In this embodiment, the chestnuts are piled up in the storage basket 2, and the conveying motor 4 rotates through the two transmission wheels 7 to drive the conveyor mesh belt 8 and several partitions 11 to convey the chestnuts toward the blanking plate 5. The present invention is a transportation equipment on the blanching device. The blanching device can be set in the recessed part of the conveyor mesh belt 8, and the height of the partition 11 is set to the height of one chestnut.

[0031] Among them, the inner wall of the partition 11 is provided with an inward moving mechanism 101, which includes a placeholder plate 14, and the outer walls on both sides of the placeholder plate 14 are fixedly connected to two trapezoidal sliders 9, and the two trapezoidal sliders 9 are slidably connected to the outer wall of the partition 11 through a third slide groove 25. The outer wall of the trapezoidal slider 9 is provided with a fourth slide groove 28, and the outer wall of the trapezoidal slider 9 is slidably connected to a displacement rod 23, and the displacement rod 23 is slidably connected to the outer wall of the partition 11. The outer wall of the placeholder plate 14 is fixedly connected to two fixed frames 20, and an immersion mechanism 202 is provided between the two fixed frames 20. The immersion mechanism 202 includes a first shaft rod 30, and the first shaft rod 30 is rotatably connected to the two fixed frames 20. The outer wall of the first shaft rod 30 is fixedly connected to the main cover plate 15, and the outer wall of the main cover plate 15 is fixedly connected to two first slide rails 19. The inner walls of the two first slide rails 19 are slidably connected to the second slide rod 18, and the two second slide rods 18 are fixedly connected to the same auxiliary cover plate 13.

[0032] Among them, the outer wall of the partition 11 is fixedly connected to the second connecting plate 27, the outer wall of the second connecting plate 27 is fixedly connected to the first spring 26, the end of the first spring 26 away from the second connecting plate 27 is fixedly connected to the first connecting plate 24, and the first connecting plate 24 is fixedly connected to the outer wall of the partition 11.

[0033] In this embodiment, when the auxiliary cover plate 13 and the main cover plate 15 rotate clockwise from the left side of the conveyor mesh belt 8, the contact plate 6 is located below the auxiliary cover plate 13 and the main cover plate 15. The height of the contact plate 6 is slightly higher than the main cover plate 15 and the auxiliary cover plate 13. Therefore, when the partition 11 approaches the contact plate 6 with the auxiliary cover plate 13 and the main cover plate 15 along with the conveyor mesh belt 8, the contact plate 6 will contact the main cover plate 15 and the auxiliary cover plate 13, causing the main cover plate 15 and the auxiliary cover plate 13 to flip half a circle.

[0034] like Figure 7-Figure 9 As shown, the auxiliary cover 13 moves with the second slide bar 18 and the first slide bar 17 along the telescopic slide groove 16 on the fixed plate 12, so that the auxiliary cover 13 gradually overlaps with the main cover 15, and the pressure block 22 on the main cover 15 will press down the displacement rod 23, and the displacement rod 23 moves down along the partition 11 along the fourth slide groove 28, pushing the trapezoidal slider 9 out, and the trapezoidal slider 9 drives the placeholder plate 14 close to the partition 11 on the other side, and the side limit plate 10 is inserted into the placeholder plate 14, so that the distance between the two partitions 11 is reduced. When the two partitions 11 pass under the storage basket 2, the capacity between the two partitions 11 becomes smaller, and the chestnuts will fall into the rectangular frame formed by the placeholder plate 14, the partition 11 and the two side limit plates 10.

[0035] Among them, the outer walls of the two second sliding rods 18 are fixedly connected to the first sliding rod 17, the outer wall of the fixing frame 20 is fixedly connected to the fixing plate 12, and the first sliding rod 17 is slidably connected to the fixing plate 12 through the telescopic sliding groove 16.

[0036] Among them, the inner wall of the partition 11 is rotatably connected to two rotating shafts 31, the outer wall of the rotating shaft 31 is fixedly connected to the side limit plate 10, the two side limit plates 10 are located between the two trapezoidal sliders 9, and two second springs 32 are fixedly connected between the side limit plate 10 and the partition 11.

[0037] The outer walls on both sides of the main cover plate 15 are fixedly connected with pressure blocks 22 .

[0038] A torsion spring 29 is fixedly connected between the fixing frame 20 and the main cover plate 15 , and a second sliding groove 21 is formed on the inner wall of the placeholder plate 14 .

[0039] In this embodiment, after the two adjacent partitions 11 are removed, the main cover 15 and the auxiliary cover 13 are free from the restrictions of the contact plate 6 and the storage basket 2, and the first shaft rod 30 in the main cover 15 is reset by the elastic force of the torsion spring 29, so that the main cover 15 rotates back along the first shaft rod 30 with the auxiliary cover 13, and the auxiliary cover 13 extends again along the telescopic slide 16 with the second slide rod 18 and the first slide rod 17, and the pressure block 22 disengages from the displacement rod 23, and the displacement rod 23 is reset by the first spring 26, so that the trapezoidal slider 9 and the placeholder plate 14 return to the inner wall of the partition 11, so that the chestnut capacity between the two partitions 11 becomes larger, avoiding chestnut accumulation. After the capacity becomes larger, the cooling of the chestnuts is also promoted subsequently. The cover composed of the main cover 15 and the auxiliary cover 13 completely covers the space between the two partitions 11, and the main cover 15 and the auxiliary cover 13 are set to a water-permeable structure.

[0040] When the chestnuts between the partition 11, the main cover 15 and the auxiliary cover 13 fall into the blanching device, the chestnuts will not float on the water surface due to the limitation of the main cover 15 and the auxiliary cover 13, but will be immersed in the water. Figure 5 As shown, the partition 11 moves along the curvature of the transmission wheel 7 so that the main cover 15 and the auxiliary cover 13 are naturally opened, and the chestnuts will automatically roll into the blanking plate 5.

[0041] The specific working principle and use method of the present invention are explained in detail below: When in use, the chestnuts are piled in the storage basket 2, and the conveying motor 4 rotates through the two transmission wheels 7 to drive the conveyor belt 8 and a plurality of partitions 11 to convey the chestnuts toward the blanking plate 5. The present invention is a transportation device on the blanching device. The blanching device can be set in the concave part of the conveyor belt 8, and the height of the partition 11 is set to the height of one chestnut. Figure 4 As shown, when the auxiliary cover 13 and the main cover 15 rotate clockwise from the left side of the conveyor belt 8, the contact plate 6 is located below the auxiliary cover 13 and the main cover 15, and the height of the contact plate 6 is slightly higher than the main cover 15 and the auxiliary cover 13. Therefore, when the partition 11 approaches the contact plate 6 with the auxiliary cover 13 and the main cover 15 along with the conveyor belt 8, the contact plate 6 will contact the main cover 15 and the auxiliary cover 13, causing the main cover 15 and the auxiliary cover 13 to flip half a circle.

[0042] like Figure 7-Figure 9As shown, the auxiliary cover 13 moves with the second slide bar 18 and the first slide bar 17 along the telescopic slide groove 16 on the fixed plate 12, so that the auxiliary cover 13 gradually overlaps with the main cover 15, and the pressure block 22 on the main cover 15 will press down the displacement rod 23, and the displacement rod 23 moves down along the partition 11 along the fourth slide groove 28, pushing the trapezoidal slider 9 out, and the trapezoidal slider 9 drives the placeholder plate 14 close to the partition 11 on the other side, and the side limit plate 10 is inserted into the placeholder plate 14, so that the distance between the two partitions 11 is reduced. When the two partitions 11 pass under the storage basket 2, the capacity between the two partitions 11 becomes smaller, and the chestnuts will fall into the rectangular frame formed by the placeholder plate 14, the partition 11 and the two side limit plates 10.

[0043] When the two adjacent partitions 11 are removed, the main cover 15 and the auxiliary cover 13 are free from the restrictions of the contact plate 6 and the storage basket 2, and the first shaft rod 30 in the main cover 15 is reset by the elastic force of the torsion spring 29, so that the main cover 15 and the auxiliary cover 13 rotate back along the first shaft rod 30, and the auxiliary cover 13 extends again along the telescopic slide 16 with the second slide bar 18 and the first slide bar 17, and the pressure block 22 disengages from the displacement rod 23, and the displacement rod 23 is reset by the first spring 26, so that the trapezoidal slider 9 and the placeholder plate 14 return to the inner wall of the partition 11, so that the chestnut capacity between the two partitions 11 becomes larger, avoiding chestnut accumulation. After the capacity becomes larger, the cooling of the chestnuts is also promoted in the future. The cover composed of the main cover 15 and the auxiliary cover 13 completely covers the space between the two partitions 11, and the main cover 15 and the auxiliary cover 13 are set to a water-permeable structure.

[0044] When the chestnuts between the partition 11, the main cover 15 and the auxiliary cover 13 fall into the blanching device, the chestnuts will not float on the water surface due to the limitation of the main cover 15 and the auxiliary cover 13, but will be immersed in the water. Figure 5 As shown, the partition 11 moves along the arc of the transmission wheel 7 so that the main cover 15 and the auxiliary cover 13 are naturally opened, and the chestnuts will automatically roll into the blanking plate 5.

[0045] It is further explained that the above-mentioned fixed connection should be understood in a broad sense unless otherwise clearly specified and limited. For example, it can be welding, gluing, or one-piece molding, etc., which are common means well known to those skilled in the art.

[0046] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
