A mushroom basket unloading machine

Abstract

A mushroom basket unloading machine includes a truck unloader and a chain machine. The chain machine is located on the front side of the truck unloader, realizing automatic rack entry, basket unloading, and rack exit. During this process, there is no need for manual handling of mushroom baskets, thus avoiding the pollution problem caused by micropores due to multiple manual handling, and greatly improving production efficiency. In addition, the truck unloader and the chain machine are controlled by a control system to cooperate with each other, thus solving the problem of mismatch between the conveying speed and the racking speed during the traditional handling and racking processes.

Description

Technical Field

[0001] The present invention relates to the field of edible mushroom production equipment. Background Art

[0002] During the production process of edible mushrooms, after the mushroom bags are inoculated, they enter the mushroom cultivation room for cultivation. After cultivation in the mushroom cultivation room, the mushroom baskets need to be unloaded from the cultivation cart and transported to the edible mushroom nurturing room. The traditional unloading method usually uses manual unloading, with multiple handling and bag turning, resulting in low production efficiency. Moreover, during the handling process, the inclination of the mushroom baskets is large, causing extrusion of the material bags and easily forming micropores, which can lead to contamination. Due to the above problems, unloading equipment has gradually emerged. However, the conveying speed of the mushroom baskets of the existing mushroom basket conveying equipment cannot be reasonably coordinated with the speed of the unloading machine, and the accuracy and coordination are poor, resulting in low production efficiency.

The basket counting is performed by this counter. The side beam 53 of the frame protrudes forward beyond the frame column 35, and the length of the bottom side beam of the frame is equal to or greater than twice the length of the upper side beam of the frame.

[0059] The structure of the chain machine II is as Figures 16 - 29 shown. Chain drive shafts 81 are respectively installed between the front and rear cross beams at both ends of the frame-shaped chain machine frame 68 of the chain machine II. One end of one of the chain drive shafts 81 penetrates through the chain machine frame 68 and a drive gear 83 is installed. A motor gear 86 is installed on the output shaft of the chain motor 54. The motor gear 86 and the drive gear 83 are connected by a motor drive chain 88. The chain motor 54 is installed on the motor bracket 84. Chain gears 89 are respectively installed on the inner sides of the front and rear cross beams of the chain machine frame 68 on each chain drive shaft 81. A drive chain 79 is installed between the two chain gears 89 on the same side of the two chain drive shafts 81. By driving the chain drive shaft 81 connected thereto by the chain motor 54, the drive chain 19 and the other chain drive shaft 81 are driven to rotate. A chain adjuster 71 is provided at the chain drive shaft 81.

[0060] A longitudinal frame connecting beam 66 is installed between the front and rear cross beams of the chain machine frame 68. The frame connecting beam 66 is located between the two chain drive shafts 81. Transverse track support beams 78 are respectively installed below the two drive chains 79 on the upper part of the frame connecting beam 66. Chain support tracks 77 are respectively installed on the upper parts of the front and rear two track support beams 78. The drive chain 79 is rotatably installed on the chain support track 77; a parking space plank 72 for placing the sterilization cart 42 is longitudinally installed between the two drive chains 79. The parking space plank 72 is a three-sided baffle structure on the upper part of the bottom plate. The bottom of the parking space plank 72 is connected to the upper edges of two chain connecting frames 73 by connecting bolts 74. The lower parts of the chain connecting frames 73 are installed at both ends of the chain shaft 85 through snap rings 90, as Figures 20 - 22 shown. Each group of parking space planks on the drive chain 79 is evenly distributed. Each group of parking space planks consists of two parking space planks 72 installed with their opening directions opposite. The distance between the two parking space planks 72 in each group matches the width of the sterilization cart 42.

[0061] The front and rear ends of the parking space bridging plate 72 are installed with pulley shafts 87 through snap rings 90. Bearing pulleys 70 are installed on the pulley shafts 87 outside the parking space bridging plate 72. The bearing pulleys 70 are slidably installed on the upper surfaces of the front and rear cross beams of the chain machine frame 68. Inside the lower parts of the front and rear cross beams of the chain machine frame 68, there are support plate pulley tracks 69 for supporting the bearing pulleys 70. The support plate pulley tracks 69 are installed on the inner sides of the lower parts of the front and rear cross beams of the chain machine frame 68 through support plate connecting plates 67. The sliding tracks of the bearing pulleys 70 at the four corners of the front and rear cross beams of the chain machine frame 68 are downward-inclined frame pulley circular tracks 76. The frame pulley circular tracks 76 are formed by extending and bending the frame pulley straight tracks 75 plates. As Figure 25 shown, when the bearing pulley 70 runs on the chain machine frame, when passing through the four corners of the chain machine frame, it transitions from the upper frame pulley straight track 75 to the frame pulley circular track 76, realizing upward or downward operation. There are legs 80 at the lower part of the chain machine frame 68. During use, the sterilization vehicle 42 is placed on each group of parking space bridging plates for transmission. When the chain motor 54 drives the transmission chain 79 to move, the parking space bridging plates 72 on the transmission chain 79 also move accordingly, and the sterilization vehicle 42 placed on the parking space bridging plates 72 is transmitted to the loading position accordingly. When the parking space bridging plate 72 travels to the two ends and moves upward or downward along with the transmission chain 79, it smoothly transitions through the frame pulley circular track 76.

[0062] A connecting frame support beam 65 is installed between the front and rear two track support beams 78 at the basket loading position of the sterilization vehicle 42. Two cylinder connecting frames 64 are symmetrically installed on the front and rear of the connecting frame support beam 65. The cylinder connecting frames 64 are connected to the rear part of the cylinder 62 through frame connecting pins 63. The front end of the cylinder rod of the cylinder 62 is connected to the tail end of the plate hook 56 through a hook connecting pin 61. The middle part of the plate hook 56 is installed on the hook rotating shaft 60. Both ends of the hook rotating shaft 60 are installed on the front and rear two track support beams 78 through rotating shaft bearings 59. The plate hook 56 moves in an arc-shaped trajectory when fixing or opening the parking space bridging plate 72; An induction device 55 is installed on the frame connecting beam 66 at the basket loading position of the sterilization vehicle 42. When the induction device 55 senses that the sterilization vehicle 42 runs to the loading position along with the transmission chain 79, the chain motor 54 stops running, the parking space bridging plate 72 stops transmitting, and the cylinder 62 drives the plate hook 56 to move upward and latch onto the parking space bridging plate 72, thereby further fixing the parking space bridging plate 72. After the upper racking is completed, the plate hook 56 opens downward, and the sterilization vehicle 42 continues to be transmitted and output through the chain machine.

[0063] The working process of the chain machine is as follows:

[0064] 1. Loading and transmission: The chain machine stops transmitting. At the full racking station, a forklift loads the full rack (sterilization vehicle filled with bacteria baskets) onto the parking space bridging plates of the chain machine, and the chain machine transmits to move the sterilization vehicle forward;

[0065] 2. Sterilization cart positioning: At the unloading station, when the induction system senses that the full rack is in place, the control system operates and, through the action of cylinder 62, the latch hook 56 of the bridging plate is latched onto the bridging plate 72 of the parking space.

[0066] 3. Basket unloading: After the full rack is in place and fixed, the control system operates and, through the operation of the double-row unloading machine, pulls the bacteria baskets onto the rollers of the roller conveyor and conveys them out.

[0067] 4. Empty rack conveyance: After the full rack is emptied, the control system operates and, through the action of cylinder 62, opens the latch hook of the bridging plate, and starts the conveyance to send the empty rack cart to the empty rack station.

[0068] 5. Empty rack discharging: When the empty rack is in place, the control system operates at this time, the chain stops conveying, at the empty rack station, the latch hook of the bridging plate is opened through the action of the cylinder, at the empty rack station, the empty rack is discharged by the forklift, and at the same time, the full rack station starts to move the full rack in. While unloading the baskets, the full rack enters the chain machine, and the empty rack exits the chain machine. At this time, one cycle of rack-in, rack-up, and rack-out is completed.

[0069] As Figures 30 - 37 shown, the process of unloading the bacteria baskets is as follows:

[0070] 1. Start the control system. After the rack cart is in place and fixed, the basket handle rises.

[0071] 2. When the basket pull rod is in place and the basket is sensed to be in place, under the control of the control system, the basket handle drops through the action of the handle cylinder.

[0072] 3. Under the control of the control system, through the action of a row of push rod cylinders, the basket pull rod is pulled back, and the first row of baskets is pulled out.

[0073] 4. Under the control of the control system, through the action of a row of push rod cylinders, the first row of baskets is pulled into place (on the roller conveyor).

[0074] 5. Under the control of the control system, the first row of baskets is conveyed out through the roller conveyor, and the basket handle rises.

[0075] 6. Under the action of the control system, the roller conveyor stops conveying, the second row of push and pull rods is in place, and the basket handle drops.

[0076] 7. Under the control of the control system, through the action of the second row of pull rod cylinders, the second row of basket pull rods is pulled back, and the second row of baskets is pulled out.

[0077] 8. Under the control of the control system, the second row of baskets is pulled into place, the basket handle rises, and the baskets are conveyed out, completing one cycle of layer basket unloading. 9. Under the control of the control system, after the roller conveyor starts to convey the second row of baskets out, the lifting frame starts and stops working after sensing the position between the layers. In this way, through the layer sensor, the up and down movement of the lifting frame is controlled by the lifting motor to realize the unloading of the baskets on each layer from the cart.

[0078] The loading operation of the unloader, the conveying operation and speed of the chain machine are all controlled by the control system, and the two operate in cooperation, thus avoiding problems such as the mismatch between the unloading speed of the fungus baskets and the conveying speed of the sterilization carts.
