Description

[Detailed explanation of the idea] [Industrial application field]

The present invention relates to a storage tank body that can cope with an increase in the capacity of a conveyor-type tea leaf management device that stores an extremely large amount of fresh tea leaves while maintaining their freshness and sequentially feeds the leaves to the next steaming process.

[Background technology and problems]

Over the past few years, the so-called "conveyor type" green tea leaf management device, which is based on the idea found in Publication of Utility Model Publication No. 58-23227, has been gaining acclaim, and it has become popular not only in large-scale factories but also in medium-sized factories. It is starting to be introduced. At the same time, there has been a strong desire to increase the capacity of a single device. This is because large-scale factories have a certain amount of room in their fresh leaf chambers, and can handle extremely large amounts of fresh tea leaves by installing multiple devices in parallel, but in medium-sized factories, the fresh leaf chamber itself has a certain amount of space. This is because there are limits to the number of devices, and even if a plurality of devices could be installed in parallel, the spacing between each device would seem to be extremely wasteful. However, even if the conveyor, which is the moving floor at the bottom of the storage tank, is widened to increase the capacity, the conventional equipment is not suitable for increasing the capacity, as can be seen in the invention of Utility Model Application Publication No. 57-187046, for example. Since improvements have already been made, in order to increase the capacity further, further new ideas are required to overcome various constraints in terms of manufacturing, mechanism, use, etc. Specifically, there are the following problems. If the caterpillar plate that constitutes the conveyor were to be formed from a single, wide plate, an extremely large steel plate would have to be used, making it difficult to cut the plate. In order to ensure the section modulus of the caterpillar plate, the caterpillar plate is subjected to bending processing, etc., but it becomes necessary to newly install a large processing machine for this purpose. If there is a difference in the elongation of the left and right chains,
The caterpillar plate begins to move diagonally from side to side, and when it turns at the front and rear ends of the conveyor, it becomes bent. As the conveyor becomes wider, the drawback of insufficient ventilation to the green tea leaves in the center becomes even more obvious.

[Purpose of the invention] The present invention was made in view of the current situation.It does not require any new processing equipment, and it aims to increase the capacity of the storage tank by substantially widening the conveyor. The aim is to ensure that the fresh tea leaves in the center of the storage tank are well ventilated, and thereby to increase the capacity of a conveyor-type fresh tea leaf management device that can truly withstand practical use.

[Means to achieve the purpose]

Therefore, in order to achieve the above-mentioned object, the present invention is a permeable conveyor made by connecting a large number of caterpillar plates, with both side walls and a receiving end wall erected, and the sending end is opened to form a storage tank. In the tea leaf management device in which the conveyor is a move floor and air is blown from the bottom surface of the conveyor, the move floor is a ventilating system having a plurality of conveyors installed in parallel and an air-permeable structure that is open at the bottom provided in the parallel arrangement part. The storage tank body of a conveyor-type tea leaf management device is characterized by consisting of a cover with a chevron-shaped cross section.

[Effect of invention]

According to the conveyor-type tea leaf management device according to this invention, the width of the move floor, which is the bottom surface of the storage tank, is widened, and a large amount of tea leaves can be input, stored, and delivered. Furthermore, the wind sent to the bottom of the conveyor spreads from the cover to the fresh leaves in the center.

【Example】

Next, the present invention will be explained based on illustrated embodiments. In the case of this embodiment, the conveyor serving as the moving floor of the storage tank consists of two conveyors, a right conveyor 1 and a left conveyor 2, and each conveyor 1 and 2 has the same configuration as the conventional one, and the conventional conveyor itself can also be used. . That is, the chain 3 consists of a chain plate 4, a chain roller 5, and a chain pin 6.
Although not shown, it is installed between a driving wheel and a driven wheel that are mounted on both ends of the machine frame of the tea leaf management device, and each caterpillar plate 7 is connected between both chains 3 by chain pins 6 at both ends. These are continuous and constitute each conveyor 1, 2. In this case, the caterpillar plate 7 is connected to the chain 3.
Although the conveyor in the present invention is not limited to this, the conveyor is attached to the chain plate 4 using the chain pin 6.
Of course, it is also possible to use a method such as tightening the caterpillar plate 7 with bolts. Both conveyors 1 and 2 are arranged in parallel on the machine frame with chains 3 and 3 on one side thereof being close to each other. In addition, 8 is a bone rail at the center of the machine frame, and the chain rollers 5, 5 of the chains 3, 3 on one side are turned here. Reference numeral 9 denotes a cover provided on the side-by-side portion of both conveyors 1 and 2, and is attached along the length of the conveyor so as to cover the adjacent chain portion 10. The cover 9 itself is made of an air-permeable steel plate such as punched metal, which is bent into a chevron-shaped cross section so that the ridge lines are connected in a straight line in the center, and PVC pipes 11 as a sliding material are fitted to both lower edges of the cover. In the case of this embodiment, when installing this cover 9, its starting end is fixed to the receiving end wall 12 of the storage tank.
3, the PVC pipe 11 is simply placed on the horizontal caterpillar plates of the adjacent chain portions 10 of the left and right conveyors, but the present invention is not limited to this, and support columns are erected on the bone rail 8 at appropriate intervals, It may also be attached in a suspended manner. Thus, the right conveyor 1, the left conveyor 2, and the center cover 9 form a move floor as if a wind cylinder was placed in the center of one conveyor. In this manner, the longitudinal side walls 14 and the receiving end wall 12 are erected on the move floor thus formed to constitute the storage tank body of the green tea leaf management device. The storage tank body also includes an air blower 15 for aerating the green tea leaves from below the conveyor, a uniform loading device (not shown) for stacking the green tea leaves to a uniform height throughout the storage tank, a scraping device, a feeding device, etc. shall be attached in accordance with customary law. Therefore, if fresh tea leaves are put in, stored for a while by blowing air, etc., and driven by a scraping device etc. as needed to drive both conveyors 1 and 2 which are move floors, the required amount of fresh tea leaves can be heated to the next steam. It is supplied to the process. Although this point is exactly the same as the conventional device, in this embodiment the move floor is constructed by installing two conveyors in parallel, so the width is essentially doubled, and the width is doubled. of fresh tea leaves are stored. In addition, due to the widening of the storage tank, there is a lack of ventilation for the green tea leaves in the center of the storage tank, but the cover 9 provided in the side-by-side portion of both conveyors 1 and 2 to cover the adjacent chain portion 10 makes it possible to Like a wind cylinder, a cavity is secured in the center of the storage tank, and the blower device 15
The wind from here spreads to the tea leaves in the center,
Removes respiratory heat and maintains freshness. In addition, although the conveyor is actually made wider, in reality, right conveyor 1 and left conveyor 2 are completely different conveyors, so chain 3 on the left and right
Even if the elongation of the conveyor belt differs, the expansion and contraction can be adjusted independently, and the caterpillar plate will not advance obliquely and bend at the turning section at the front and rear ends of the conveyor. Furthermore, since the caterpillar board can be made substantially wider with a conventional size or a smaller size, there is no need to prepare new large-scale processing equipment, and the board itself is easy to cut.

[Effect of the idea]

As mentioned above, the present invention aims to increase the capacity of the storage tank by substantially widening the conveyor, and at the same time, it is possible to effectively and reliably ventilate the fresh tea leaves in the center of the storage tank, which tends to be in short supply, so that a large amount of tea leaves can be stored. It can be stored to maintain its freshness.
