Description

Technical Field

[0001] This utility model relates to the field of visibility meters, and in particular to a drying production line. Background Technology

[0002] Peanuts are an important economic crop, and drying is a crucial step in subsequent processing and storage. Traditional peanut drying methods mainly rely on natural sun-drying and ordinary dryers. However, these methods have significant drawbacks. For example, natural sun-drying requires a large amount of space, is greatly affected by weather, is inefficient, and makes it difficult to ensure uniform drying. While ordinary dryers can improve efficiency to some extent, their simple structure makes them unsuitable for large-scale production lines. Furthermore, in the use of existing drying equipment, the transportation and loading / unloading of peanuts often require manual labor, resulting in high labor intensity, low efficiency, and hindering the realization of modern and automated production requirements.

[0003] Currently, Chinese patent CN 216245224 U proposes a hot air circulating single-sided lifting box dryer. Its design, through the roller shutter door and hot air circulation structure, effectively improves drying efficiency, reduces energy consumption, and optimizes the workshop environment. Specifically, the device controls the discharge of humid air in the early stage of drying and the circulation of hot air in the later stage of drying by opening and closing the roller shutter door. In addition, the upper box body is hinged to the lower base and the lifting device is used to achieve single-sided lifting, which utilizes the height difference to quickly output materials, thereby improving the orderliness and efficiency of material discharge. These features enable the equipment to exhibit good drying effect when operating alone and are suitable for small-batch or intermittent drying operations.

[0004] However, in actual large-scale assembly line drying applications, due to the height of the equipment, it becomes inconvenient for staff to manage the upper chamber during operation (such as cleaning residual materials or spreading materials). This limitation not only increases the difficulty of operation but also affects the overall efficiency of the production line. Therefore, a drying production line is proposed to solve the above problems. Utility Model Content

[0005] The main purpose of this utility model is to provide a drying production line that solves the problem of inconvenience for workers to manage the upper chamber during operation.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a drying production line, including two rows of single-sided lifting box dryers arranged opposite each other, and a feeding crane mounted above the two rows of single-sided lifting box dryers. The discharge ends of the two rows of single-sided lifting box dryers are arranged opposite each other. The feeding crane feeds the two rows of single-sided lifting box dryers through a hoisted hopper. One or two feeding conveyor belts are arranged between the two rows of single-sided lifting box dryers. The single-sided lifting box dryers in each row are arranged in pairs.

Guide rails are installed on the top of the track support frames, and multiple movable platforms are mounted on the two guide rails. The movable platforms are aligned with either side of the worktable by moving the guide rails.

[0010] In the preferred embodiment, the mobile platform includes a mobile platform, the bottom of which is equipped with a pair of self-driven wheels mounted on a guide rail, and the top surface of the mobile platform is flush with the support platform.

[0011] In the preferred embodiment, a second guardrail is provided on the top of the movable platform, both ends of which are open and hinged with doors.

[0012] In the preferred embodiment, the movable platform is also equipped with a connecting platform that can extend to both ends;

[0025] Example 1

[0026] like Figure 1-3 As shown, a drying production line includes two rows of single-sided lifting box dryers 2 arranged opposite each other, and a feeding crane 1 erected above the two rows of single-sided lifting box dryers 2. The single-sided lifting box dryers 2 adopt a hot air circulation single-sided lifting box dryer proposed in Chinese Patent CN216245224 U. The discharge ends of the two rows of single-sided lifting box dryers 2 are arranged opposite each other. The feeding crane 1 feeds the two rows of single-sided lifting box dryers 2 through the hoisted hopper, realizing automated feeding and reducing the intensity of manual labor.

[0027] One or two feeding conveyor belts 3 are provided between the two rows of single-sided lifting box dryers 2. In this embodiment, two feeding conveyor belts 3 are preferred, located on the discharge end side of the two rows of single-sided lifting box dryers 2, respectively, to receive the dried peanuts and transport them out of the production line.

[0028] Each row consists of two single-sided lifting box dryers 2, and a side workbench 4 is set between the two single-sided lifting box dryers 2 in each group. The side workbench 4 allows the staff to stand on it and manage the single-sided lifting box dryers 2 in the group from the side.

[0029] The top of the feeding conveyor belt 3 is also equipped with a middle movable worktable 5 located between the two rows of single-sided lifting box dryers 2. The middle movable worktable 5 can be moved to align with either side worktable 4, so that either worktable 4 can be logged onto the middle movable worktable 5. At the same time, the middle movable worktable 5 can be moved to the front of either single-sided lifting box dryer 2, so as to carry out material sorting, maintenance or cleaning work on the front side of either single-sided lifting box dryer 2.

[0030] In the preferred embodiment, the side workbench 4 includes a support frame 401, which supports the entire workbench and ensures its stability. The top of the support frame 401 is provided with a support platform 402, which provides a work platform for the operator. The height of the platform is consistent with that of the dryer. The side of the support frame 401 is also provided with a ladder 403 for climbing onto the support platform 402, which facilitates the operator to go up and down the support platform 402.

[0031] In the preferred embodiment, a first guardrail 404 is provided on the top of the support platform 402, and both ends of the first guardrail 404 are open. The ladder 403 is provided at the opening at the outer end of the first guardrail 404, which facilitates the workers to go up and down the support platform 402, and to pass through the support platform 402 and climb onto the intermediate movable workbench 5.

[0032] In the preferred embodiment, the intermediate movable workbench 5 includes two track support frames 501 arranged opposite each other. A guide rail 502 is installed on the top of the track support frame 501. Multiple movable platforms 503 are mounted on the two guide rails 502. The movable platforms 503 are aligned with either side of the workbench 4 by moving the guide rails 502, thereby facilitating the worker to climb onto the intermediate movable workbench 5 from either side of the workbench 4.

[0033] It should be noted that the two track support frames 501 are installed between the single-sided lifting box dryer 2 and the feeding conveyor belt 3, and the spacing does not affect the normal operation of the two. In addition, the specific number of mobile platforms 503 can be determined according to the actual length of the production line and the work requirements.

[0034] In the preferred embodiment, the mobile platform 503 includes a mobile table 5030. The bottom of the mobile table 5030 is provided with a pair of self-driving wheels 5031 mounted on a guide rail 502. The mobile table 5030 moves on the guide rail 502 by being driven by the self-driving wheels 5031. The self-driving wheels 5031 are ordinary commercially available products with parking function, so they will not be described in detail here. The top surface of the mobile table 5030 is flush with the support table 402.

[0035] In the preferred embodiment, the top of the movable platform 5030 is provided with a second guardrail 5032. Both ends of the second guardrail 5032 are open and are hinged with an opening and closing door 5044. This allows the platform to move through the opening at the end of the opening and closing switch of the opening and closing door 5044, ensuring the safety of the staff on it and facilitating the staff to get on and off.

[0036] Example 2

[0037] Further explanation in conjunction with Example 1, such as Figure 3-4In order to avoid unnecessary safety accidents caused by the gap between the middle movable worktable 5 and the side worktable 4, the movable worktable 5030 is also provided with a connecting platform that can be extended to both ends in this embodiment.

[0038] The connecting platform includes a telescopic cavity 5033 disposed in the movable platform 5030. Both ends of the telescopic cavity 5033 are open, and an expansion cavity 5034 is disposed on its top. An expansion platform 5040 that can extend and retract to both ends is disposed in the telescopic cavity 5033. A drive mechanism for driving the two expansion platforms 5040 to extend and retract simultaneously is disposed in the expansion cavity 5034.

[0039] With this design, the two extension platforms 5040 can be driven to extend outwards simultaneously through the drive mechanism, thereby forming an effective connection with the side worktable 4.

[0040] In a preferred embodiment, the drive mechanism includes a positive and negative threaded screw 5036 rotatably disposed in the expansion cavity 5034, two limiting slide rods 5035, and a drive motor 5038. The positive and negative threaded screw 5036 is rotatably disposed in the expansion cavity 5034 via bearings at both ends. The two limiting slide rods 5035 are respectively fixedly disposed on both sides of the positive and negative threaded screw 5036. A driven gear 5037 is fixedly fitted in the middle of the positive and negative threaded screw 5036. The output end of the drive motor 5038 is provided with a transmission gear 5039 that meshes with the driven gear 5037. Thus, the drive motor 5038 can drive the transmission gear 5039 to rotate, thereby causing the positive and negative threaded screw 5036 to rotate through the driven gear 5037.

[0041] Furthermore, three sleeves 5041 are provided at the top of the inner end of the expansion platform 5040. Two of the sleeves 5041 slide outside the two limiting slide rods 5035, and the other sleeve 5041 is an internally threaded sleeve, which is outside the opposite threads of the positive and negative threaded screws 5036. The sleeves 5041 of the two expansion platforms 5040 are respectively threaded onto the positive or negative threads of the positive and negative threaded screws 5036.

[0042] With this design, the rotation of the forward and reverse threaded screws 5036 can drive the two extension platforms 5040 to move in opposite or disjointed directions under the restriction of the limiting slide rods 5035.

[0043] In addition, the telescopic cavity 5033 is provided with limiting grooves 5042 corresponding to the expansion platform 5040 on both side walls, and the expansion platform 5040 is provided with limiting blocks 5043 that slide in cooperation with the corresponding limiting grooves 5042 on both sides. By utilizing the sliding cooperation between the limiting blocks 5043 and the limiting grooves 5042, the stability and support effect of the overall movement can be effectively improved.

[0044] In the preferred embodiment, the side workbench 4 is provided with a support platform 405 for supporting the end of the extended platform 5040 at one end near the middle movable workbench 5, which effectively improves the stability of the workers walking on it.

[0045] It should be noted that the side worktable 4 and the middle movable worktable 5 are respectively equipped with matching locators and positioning targets on opposite sides to achieve precise positioning between them.

[0046] The above embodiments are merely preferred technical solutions of this utility model and should not be considered as limitations on this utility model. The protection scope of this utility model should be the technical solution described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
