Description

Technical Field

[0001] The utility model belongs to the technical field of mushroom stick cultivation, and specifically relates to a sterilization device for mushroom stick cultivation. Background Art

[0002] Mushroom sticks are the cultivation substrate for edible fungi. The fungi are inoculated into the base material of the mushroom sticks and cultivated to produce edible fungi. The base material of the mushroom sticks is generally straw and corn cobs, etc. Mugwort can also be added to the base material of the mushroom sticks. The medicinal components of wormwood are decomposed and absorbed by the mycelium of edible fungi, and the cultivated edible fungi have a fresh taste.

[0003] In order to prevent contamination by foreign bacteria and ensure the quality and yield of edible fungi, the mushroom sticks need to be sterilized before inoculation. Specifically, the mushroom sticks are placed on a placement rack, and then the placement rack is pushed into a sterilization tank and sterilized by passing high-temperature steam. However, there are the following problems:

[0004] (1) The bottom surface of the mushroom stick is in contact with the placement rack, the contact area between the high-temperature steam and the bottom surface of the mushroom stick is small, and adjacent mushroom sticks are easy to contact each other. The contact area between the high-temperature steam and the surrounding of the mushroom stick is small, and the heat transfer speed is slow, which affects the sterilization efficiency;

[0005] (2) The sterilization tank is deep, which makes it inconvenient to load and unload the mushroom sticks and is not automated enough, affecting the overall efficiency of the sterilization work. Utility Model Content

[0006] In order to solve the problems of small contact area between high-temperature steam and mushroom sticks and insufficient automation of material input and output during mushroom stick sterilization, the utility model aims to provide a sterilization device for mushroom stick cultivation with high sterilization efficiency.

[0007] The technical solution is: a sterilization device for cultivating mushroom sticks, comprising a sterilization tank, the front end of which is open and provided with a sealing cover, a steam inlet pipe installed on the side wall of the sterilization tank, at least three brackets are connected at intervals inside the sterilization tank, a row of transmission rollers are rotatably connected to the front bracket and the rear bracket at intervals, a reduction motor for driving the transmission rollers to rotate is connected to the outside of the sterilization tank, two transmission rollers with the same height position form a pair, a transmission belt for transmitting mushroom sticks is wound between each pair of transmission rollers, and the transmission belt is divided into a placement section and a connection section, the placement section is provided with a small through hole, and the connection section is provided with a large through hole.

[0008] Furthermore, the sterilization device for mushroom stick cultivation also includes a dividing strip, and the conveyor belt is connected to a row of dividing strips for separating the mushroom sticks at intervals on the placement section, and the dividing strips divide the placement section into a row of placement areas.

[0009] Furthermore, the sterilization device for cultivating mushroom sticks also includes supporting rollers, and a row of supporting rollers for supporting the conveyor belt are rotatably connected to the middle bracket at intervals, and the supporting rollers are located between the placement section and the connection section.

[0010] Furthermore, the sterilization device for cultivating mushroom sticks also includes vertical partitions. A plurality of vertical partitions for separating mushroom sticks are connected inside the sterilization tank. The vertical partitions are provided with long holes having the same number as the conveyor belts, and the conveyor belts are allowed to pass through the long holes.

[0011] Furthermore, the sterilization device for cultivating mushroom sticks also includes a rear baffle for blocking the mushroom sticks, and the interior of the sterilization tank is connected to the rear baffle close to the rear end of the conveyor belt.

[0012] Furthermore, the sterilization device for cultivating mushroom sticks also includes a lifting rod, an electric push rod and an inclined plate. The front end of the sterilization tank is provided with a lifting rod that slides up and down, the outside of the sterilization tank is connected to an electric push rod, the telescopic rod of the electric push rod is connected to the lifting rod, and the bottom end of the lifting rod is connected to an inclined plate for guiding the mushroom sticks, and the inclined plate has multiple partitions.

[0013] The beneficial effects are: 1. The conveyor belt transports the mushroom sticks in the placement area backwards, the dividing strips separate the mushroom sticks in the front and back directions, and the vertical partitions separate the mushroom sticks in the left and right directions. The high-temperature steam enters between the placement section and the connecting section of each conveyor belt through the long holes, and then passes through the small through holes to enter the bottom surface of the mushroom sticks, and passes through the large through holes to enter the top surface and the surrounding areas of the mushroom sticks, thereby increasing the contact area between the high-temperature steam and the mushroom sticks and effectively improving the sterilization efficiency. The conveyor belt then outputs the mushroom sticks, and the loading and unloading are automated with higher efficiency.

[0014] 2. When the conveyor belt transports the sterilized mushroom sticks forward, the mushroom sticks roll down along the inclined plate one by one under the action of gravity. The inclined plate guides the mushroom sticks to facilitate the discharge of the mushroom sticks. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0024] The preferred technical solution of the present utility model is described in detail below with reference to the accompanying drawings.

[0025] Example 1: A sterilization device for cultivating mushroom sticks, reference Figure 1-Figure 6 , including a sterilization tank 1, a sealing cover 2, a steam inlet pipe 3, a bracket 4, a driving roller 5, a reduction motor 51 and a conveyor belt 6. The front end of the sterilization tank 1 is open and provided with a sealing cover 2. Three steam inlet pipes 3 are installed on the side wall of the sterilization tank 1. The structure of the sterilization tank 1 and the specific principle of sterilizing the bacteria stick are the existing technology. Four brackets 4 are fixedly connected at intervals inside the sterilization tank 1. A row of driving rollers 5 are rotatably connected to the front bracket 4 and the rear bracket 4 at intervals. A reduction motor 51 for driving the driving roller 5 to rotate is connected to the outside of the sterilization tank 1. The output shaft of the reduction motor 51 is connected to the driving roller 5. Two driving rollers 5 with the same height position are a pair. A conveyor belt 6 for transmitting the bacteria stick is wound between each pair of driving rollers 5. The conveyor belt 6 is divided into a placement section 61 and a connecting section 62. A small through hole 63 is opened on the placement section 61, and a large through hole 64 is opened on the connecting section 62.

[0026] refer to Figure 2 , Figure 4 , Figure 5 and Figure 6 The sterilization device for cultivating mushroom sticks also includes a partition bar 7. A row of partition bars 7 are fixedly connected to the placement section 61 of the conveyor belt 6 at intervals. The partition bars 7 divide the placement section 61 into a row of placement areas. The partition bars 7 are used to separate the mushroom sticks.

[0027] refer to Figure 2 and Figure 3The sterilization device for cultivating mushroom sticks also includes support rollers 8. A row of support rollers 8 are rotatably connected to the two middle brackets 4 at intervals. The support rollers 8 are located between the placement section 61 and the connection section 62. The support rollers 8 are used to support the middle part of the conveyor belt 6.

[0028] refer to Figure 1 , Figure 2 , Figure 3 and Figure 7 The sterilization device for cultivating mushroom sticks also includes vertical partitions 9. Four vertical partitions 9 are fixedly connected inside the sterilization tank 1. The vertical partitions 9 are each provided with long holes 91 having the same number as the conveyor belt 6. The long holes 91 are for the conveyor belt 6 to pass through. The vertical partitions 9 are used to separate the mushroom sticks on the conveyor belt 6. The distance between two adjacent vertical partitions 9 is greater than the length of the mushroom sticks.

[0029] refer to Figure 2 The sterilization device for cultivating mushroom sticks also includes a rear baffle 10, which is fixedly connected to the rear side of the sterilization tank 1. The rear baffle 10 is close to the rear end of the conveyor belt 6, and is used to block the mushroom sticks on the conveyor belt 6.

[0030] First, the reduction motor 51 is controlled to drive the transmission roller 5 on the front bracket 4 to rotate clockwise, and the transmission belt 6 is rotated clockwise with the cooperation of the transmission roller 5 on the rear bracket 4 until Figure 2 The rearmost placement area is located above the front end of the conveyor belt 6 .

[0031] The mushroom sticks are placed at intervals in the placement area above the front end of the conveyor belt 6, and the reduction motor 51 is controlled to make the conveyor belt 6 continue to rotate clockwise. The conveyor belt 6 transports the mushroom sticks backwards and then places the mushroom sticks. The support roller 8 plays a supporting role until the conveyor belt 6 rotates to the initial position. The mushroom sticks are blocked by the rear baffle 10 to prevent the mushroom sticks on the conveyor belt 6 from falling. At this time, the placement area is filled with mushroom sticks. There are six layers of mushroom sticks, and each layer has three rows of mushroom sticks. The mushroom sticks are separated in the front and back directions by the dividing strips 7, and the mushroom sticks are separated in the left and right directions by the vertical partitions 9 to prevent adjacent mushroom sticks from contacting each other and ensure that there is a gap between adjacent mushroom sticks for high-temperature steam to pass through.

[0032] Close the sealing cover 2, and introduce high-temperature steam through the steam inlet pipe 3 to sterilize the mushroom sticks. The high-temperature steam passes through the long hole 91 of the vertical partition 9 and enters between the placement section 61 and the connecting section 62 of each conveyor belt 6. The high-temperature steam between the placement section 61 and the connecting section 62 then passes through the small through hole 63 from bottom to top and enters the bottom surface of the mushroom stick. The high-temperature steam between the placement section 61 and the connecting section 62 will also pass through the large through hole 64 from top to bottom and enter the top surface and surrounding areas of the mushroom stick, thereby effectively increasing the contact area between the high-temperature steam and the mushroom stick, accelerating heat transfer, and effectively improving the sterilization efficiency.

[0033] After the sterilization is completed, the reduction motor 51 is controlled to make the driving roller 5 and the conveyor belt 6 rotate counterclockwise, and the conveyor belt 6 conveys the mushroom sticks forward, so that the mushroom sticks can be discharged. The feeding and discharging of the mushroom sticks are automated and more efficient.

[0034] Embodiment 2: Based on embodiment 1, Figure 1 and Figure 8 As shown, the sterilization device for cultivating mushroom sticks also includes a lifting rod 11, an electric push rod 12 and an inclined plate 13. Two lifting rods 11 that slide up and down are provided at the front end of the sterilization tank 1. Two electric push rods 12 are bolted to the outer side of the front of the sterilization tank 1. The telescopic rods of the two electric push rods 12 are respectively connected to the top ends of the two lifting rods 11. The bottom ends of the two lifting rods 11 are commonly connected with an inclined plate 13 for guiding the mushroom sticks. The inclined plate 13 has four partitions 131.

[0035] When the conveyor belt 6 on the lower side rotates counterclockwise to transport the sterilized mushroom sticks on the lower layer forward, the mushroom sticks on the lower layer roll down along the inclined plate 13 in sequence under the action of gravity. The inclined plate 13 guides the mushroom sticks, and the partition 131 plays the role of separating the mushroom sticks. Then, the telescopic rod of the electric push rod 12 is controlled to shorten, so that the lifting rod 11 and the inclined plate 13 rise, and the inclined plate 13 can guide the mushroom sticks on other layers, which is convenient for the discharge of the mushroom sticks.
