Description

Technical Field

[0001] The utility model relates to a fermentation bed material distributing mechanism, in particular to a fermentation bed material distributing mechanism capable of adjusting the height of a material layer, and belongs to the technical field of fermentation auxiliary equipment. Background Art

[0002] Traditional rectangular fermentation beds are relatively simple to produce, typically using manual spreading. After fermentation is complete, the material is unloaded by manual forklift, which is labor-intensive. These open-work environments create poor sanitary conditions, reducing product quality. With increasing production capacity and technological advancements, large rectangular fermentation beds are increasingly being equipped with automatic spreading machines.

[0003] Chinese utility model patent publication number CN 213772067U discloses a rectangular fermentation bed inoculation mixer distributing machine. The distributing machine's chassis is supported by wheels on a track positioned above the long sides of the rectangular fermentation bed. A spreading auger and a leveling device are located below the distributing machine chassis, with the leveling device positioned behind the spreading auger. An inoculation mixer is mounted above the chassis, with a pre-mixer stacked above the inoculation mixer. Dry material is air-fed into the mixer's feed port through a feed pipe, while bacterial liquid is also introduced through a bacterial liquid pipe. After thorough mixing within the mixer, both are discharged through the mixer's discharge port into the fermentation bed. When the material reaches a certain height within the bed, the distributing machine activates, with the distributing auger conveying the material across the width of the fermentation bed and leveling it through a leveling mechanism. Furthermore, the distributing machine travels along the track, distributing material across the entire rectangular fermentation bed.

[0004] The mixed material distributing machine has the following shortcomings: 1. The distributing auger and the distributing walking frame are fixed integral structures. To adjust the distributing height on the fermentation bed, the waist-shaped bolts of the rear baffle of the distributing auger need to be removed one by one. The installation workload is large, time-consuming and labor-intensive, and the downtime is long, which affects the production line's operating rate, production continuity, and economic benefits.

[0005] 2. The workload is large during disassembly, and many parts need to be disassembled, which may easily damage other parts;

[0006] 3. The position and height of each scraper need to be readjusted during installation, and the surface of the pile may be uneven due to uneven installation;

[0007] 4. There is no material level sensor at the end, which cannot sense the material status. This can easily cause material accumulation or lack of material on one side, requiring manual intervention to monitor the material, increasing labor costs.

[0008] 5. In order to shorten the return travel time of the fabric placing machine, a dual-speed motor is used for travel. The dual-speed motor is prone to heat and high power consumption when running continuously at low frequency. Utility Model Content

[0012] In order to solve the above technical problems, the utility model provides a fermentation bed distributing mechanism with adjustable material layer height, including a walking platform, a mixer is installed on the walking platform, and the four corners of the walking platform are respectively fixed with upwardly extending fixed columns, the tops of the four fixed columns are connected as a whole through a top rectangular frame, and lifting cross frames are respectively provided between the fixed columns on the same side, and a lifting drive mechanism for driving the lifting cross frame to float is installed on the top rectangular frame; the two ends of the lifting cross frame are respectively connected with downwardly extending lifting vertical rods, the lower ends of each lifting vertical rod respectively pass through the walking platform and the lower ends are respectively connected to the corners of the lifting platform, a distributing auger extending along its length direction is fixed on the lifting platform, and a scraper assembly is provided on the rear side of the forward direction of the distributing auger.

[0013] As an improvement of the present invention, lifting guide rails are fixed on the facing end surfaces of the fixed columns on the same side, and the lifting guide rails are respectively provided with matching lifting sliders, and the lifting sliders are respectively fixedly connected to the corresponding lifting vertical rods.

[0014] As a further improvement of the present invention, the lifting drive mechanism includes a lifting reducer, and the two lifting reducers are respectively fixed at the middle of the short side of the top rectangular frame.

[0015] As a further improvement of the present invention, the middle sections of the fixed columns on the same side are connected via a middle cross frame.

[0016] As a further improvement of the present invention, a material level detection assembly is provided on the front side of the forward direction of the fabric auger, and the material level detection assembly includes an adjusting screw, and a downwardly extending vertical detection bracket is fixed to the lower end of the adjusting screw, and a material layer signal switch is installed in the middle of the vertical detection bracket, and the lower end of the vertical detection bracket is hinged with an inclined swing frame, and the lower end of the swing frame is provided with a material layer pushing end that is bent and extended downward, and the upper end of the swing frame is connected to a signal transmitting bracket close to the material layer signal switch.

[0017] As a further improvement of the present invention, a drag chain suspension assembly extending horizontally outward is provided on one side of the walking platform.

Raising and lowering the material-feeding auger and scraper platform only requires minimal manual intervention, effectively improving the automation rate of the equipment.

[0024] 5. Since the travel reduction motor will be started only after the material level sensor detects a signal and runs intermittently, it can be replaced by an ordinary reduction motor, which can reduce heat, save energy and increase efficiency, extend the service life of the motor, and significantly improve economic benefits.

[0039] In the following description of the present invention, the terms "upper", "lower", "front", "back", "left", "right", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not mean that the device must have a specific direction.

[0040] In order to make the technical means, creative features, objectives and effects of the present invention easier to understand, the present invention is further described below with reference to specific figures. Obviously, the embodiments described are only a part of the present invention, not all of the embodiments.

[0041] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0042] like Figures 1 to 5 As shown, the fermentation bed feeding mechanism with adjustable material layer height of the present invention includes a walking platform 1, a walking drive mechanism 2, a mixer 3, a gantry 4, a lifting drive mechanism 5, a lifting frame 6, a feeding auger 7, and a scraper assembly 8. Walking track wheels 1b are respectively provided below the four corners of the walking platform 1, and the axles of the left and right walking track wheels 1b are connected by a synchronous long shaft 1a.

[0043] A travel drive reducer 2b is mounted on one end of the travel platform 1. The input of the travel drive reducer 2b is driven by a travel reduction motor 2a, and a travel drive sprocket 2c is mounted on the output of the travel drive reducer 2b. A platform drive sprocket 1c is mounted on the end of at least one synchronous long shaft 1a, and the travel drive sprocket 2c is connected to the platform drive sprocket 1c via a chain. The travel reduction motor 2a drives the travel drive sprocket 2c via the travel drive reducer 2b, which in turn drives the platform drive sprocket 1c via the chain. The platform drive sprocket 1c drives the left and right travel track wheels 1b synchronously via the synchronous long shaft 1a, thereby enabling the travel platform 1 to travel along the length of the rectangular fermentation bed. The use of sprocket-type travel track wheels 1b ensures smooth travel, eliminating slippage and deviation.

[0044] A horizontally extending drag chain suspension assembly 1d is installed on one side of the platform 1 to support the corresponding cables and hoses when the platform 1 is in motion. The integrated feeding structure reduces customer investment costs and has significant economic benefits.

[0045] Mixer 3 is mounted on platform 1. The outlet of material conveying pipe 3a is connected to the mixer's feed port via a reducer. Simultaneously, the outlet of bacterial liquid injection pipe 3b is also connected to the mixer's feed port. Dry material enters the mixer's feed port via pneumatic conveying pipe 3a, while bacterial liquid enters the mixer's feed port via bacterial liquid injection pipe 3b. After being thoroughly mixed within mixer 3, the dry material falls from the mixer's discharge port into the rectangular fermentation bed, initially landing at one end of the bed's width, where it awaits distribution along the width of the bed by the distribution mechanism.

[0046] A gantry 4 is fixedly installed above the walking platform 1, comprising fixed columns 4a, a top rectangular frame 4c and a middle cross frame 4d. The four corners of the walking platform 1 are respectively fixed with upwardly extending fixed columns 4a. The tops of the four fixed columns 4a are connected as a whole through the top rectangular frame 4c, and the middle sections of the fixed columns 4a on the same side are respectively connected through the middle cross frame 4d to improve the rigidity and strength of the gantry 4.

[0047] A lifting drive mechanism 5 is mounted on the top rectangular frame 4c to drive the lifting frame 6 up and down. The lifting frame 6 comprises a lifting crossbeam 6a, lifting vertical rods 6b, and a lifting platform 6d, all connected together. The lifting crossbeam 6a extends along the forward direction of the walking platform 1 and is located between the fixed columns 4a on the same side. Lifting vertical rods 6b are connected to each end of the lifting crossbeam 6a. Each lifting vertical rod 6b extends downward and passes through the avoidance groove of the walking platform 1. The lower end of each lifting vertical rod 6b is connected to the corner of the lifting platform 6d.

[0048] The lifting drive mechanism 5 includes a lifting motor 5a, a lifting reducer 5b, and a boom 5d. The two lifting reducers 5b are fixed to the middle of the short sides of the top rectangular frame 4c, with their input axes horizontal and their output axes vertical. The input of one lifting reducer 5b is driven by the lifting motor 5a. The inputs of the two lifting reducers 5b are connected by a connecting rod assembly 5c to ensure synchronous movement on both sides. The outputs of the two lifting reducers 5b are connected to the middle of the lifting crossbeam 6a on the same side via a downward-extending boom 5d. The lifting motor 5a drives the boom 5d upward via the lifting reducer 5b. The lower end of the boom 5d pulls the lifting frame 6 up and down to adjust the height of the fermentation bed material layer.

[0049] The connecting rod's midsection is connected via a flange coupling, which is supported on the top rectangular frame 4c via a floating bearing sleeve. This ensures reliable torque transmission while also ensuring good coaxiality and maintainability for the lift reducers 5b at both ends. The unique design of the separate lift reducer 5b ensures that the position of the lift frame 6 relative to the machine body remains unchanged after each disassembly and maintenance of the lift drive mechanism 5, eliminating the need for repeated adjustment.

[0050] Lifting rails 4b are fixed to the facing end faces of the fixed columns 4a on the same side. These rails are equipped with matching lifting sliders 6c, which are fixedly connected to corresponding lifting vertical rods 6b. The cooperation between the lifting sliders 6c and the lifting rails 4b effectively achieves vertical lifting while ensuring good straightness of the lifting frame 6, ensuring smooth lifting and reducing resistance.

[0051] A feeding auger 7 is fixed to the lifting platform 6d and extends axially along the lifting platform 6d. The feeding auger 7 is driven by an auger motor 7a. A scraper assembly 8 is provided on the rear side of the feeding auger 7 in the direction of its forward movement. The feeding auger 7 and the scraper assembly 8 rise and fall with the lifting platform 6d to adjust the material layer height.

[0052] A material level detection assembly 9 is installed at the front side of the fabric auger 7 in the forward direction. This assembly includes an adjustment screw 9a. A downward-extending vertical detection bracket 9b is fixed to the lower end of the adjustment screw 9a. A switch mounting bracket 9c is fixed in the middle of the vertical detection bracket 9b. A material layer signal switch is mounted on the switch mounting bracket 9c. An inclined swing bracket 9d is hinged at the lower end of the vertical detection bracket 9b. The lower end of the swing bracket 9d is equipped with a downward-bending material layer push end. The upper end of the swing bracket 9d is connected to a signal transmission bracket 9e near the material layer signal switch. The material layer signal switch can be a proximity switch, a travel switch, or other sensor.

[0053] First, start the lifting motor 5a to adjust the material distribution auger 7 and the scraper assembly 8 to the predetermined distribution height. Then start the auger motor 7a to drive the material distribution auger 7 to rotate. The material distribution auger 7 distributes the material along the width of the rectangular fermentation bed and relies on the scraper assembly 8 to scrape the top of the material layer flat. When the material reaches the set height in the bed, the material pushes the lower end of the swing frame 9d to rotate the swing frame 9d, triggering the material layer signal switch to send a signal, the walking platform 1 moves forward, and the scraper assembly 8 flattens the material. After moving a certain distance, the material leaves the lower end of the swing frame 9d, the material layer signal switch loses the signal, and the walking platform 1 stops moving forward. This cycle continues until the distribution is completed, realizing the automatic control of the distribution machine to continuously advance the distribution. The travel reduction motor 2a only runs intermittently after the sensor feedback signal, reducing the heat caused by low-frequency operation.
