Description

Technical Field

[0001] This utility model relates to the field of carbon-based fertilizer production, and in particular to a mixing device for producing wood chip carbon-based fertilizer. Background Technology

[0002] Wood chip carbon-based fertilizer uses wood chips (such as bamboo, straw, and other biomass materials) as raw materials. These are processed into porous biochar through high-temperature pyrolysis and then mixed with inorganic fertilizers such as nitrogen, phosphorus, and potassium. It is mainly used to improve soil structure, enhance nutrient utilization, and promote plant growth. Biochar can increase soil porosity, improve aeration and drainage, reduce compaction, and create a good growth environment for roots. Biochar can adsorb nutrients and slowly release fertilizer effects, increasing fertilizer utilization by 30%-50% while reducing nutrient loss. Wood charcoal contains elements such as carbon and potassium, which can be directly absorbed by plants, enhancing root vitality, improving resistance to diseases and pests, and improving fruit quality.

[0003] However, in the existing technology, the production process of wood chip carbon-based fertilizer requires stirring the fertilizer raw materials. Conventional stirring structures cannot meet the requirements for rapid stirring and preparation of fertilizer, and it is not convenient to control the output of fertilizer. Utility Model Content

A first conveying mechanism and a second conveying mechanism are respectively installed at the bottom of the lower mixing tank and the upper mixing tank.

[0006] Both the first and second feeding mechanisms include a feeding box. A guide plate is fixedly installed on the inner side of the upper end of the feeding box. A feeding control plate is slidably connected to the lower end face of the guide plate. A transmission screw is installed on the inner side of the bottom end of the feeding control plate.

A vibration motor is fixedly installed at the other end of the feeding box.

[0007] Preferably, the segmented mixing mechanism further includes a discharge sleeve plate fixedly connected to the bottom of the lower mixing tank, and a sealing cover is fixedly installed on the upper end of the upper mixing tank, with a feed inlet on the upper surface of the sealing cover.

[0008] Preferably, the synchronous stirring mechanism includes a first drive motor, which is fixedly connected to the mixing tank. The output end of the first drive motor is connected to a first drive shaft via a coupling.

[0009] Preferably, the upper mixing tank is connected to the inlet, and the upper and lower ends of the lower mixing tank are connected to the upper mixing tank and the discharge sleeve through the first conveying mechanism and the second conveying mechanism, respectively. Both conveying boxes are fixedly connected to the lower mixing tank.

[0010] Preferably, the first drive shaft and the second drive shaft are rotatably connected to the lower mixing tank and the upper mixing tank, respectively. The inner wall of the bottom of the lower mixing tank is in contact with multiple arc-shaped scrapers. The rotation direction of the first drive shaft and the second stirring frame is clockwise. The gearbox is equipped with a planetary gear set. The first drive shaft and the second drive shaft are connected by the planetary gear set. The rotation speed of the first drive shaft is lower than that of the second drive shaft.

[0011] Preferably, the upper surfaces of the guide plate and the conveying control plate are each provided with two guide holes. The guide plate and the conveying control plate are installed in a staggered manner. One end of the transmission screw passes through the bottom end of the conveying control plate, the conveying box and the two guide plates and is connected to the second transmission motor through a coupling. The transmission screw is threadedly connected to the conveying control plate.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] 1. Raw materials are injected into the inner side of the mixing tank through the feed inlet. The first drive shaft and the second drive shaft are connected by a planetary gear set. The first drive motor drives the second drive shaft to rotate synchronously through the first drive shaft and the planetary gear set. In turn, the first drive shaft and the second drive shaft drive the first stirring frame, the second stirring frame and multiple arc-shaped scrapers to rotate clockwise. The multiple second stirring frames can perform pre-mixing operation on the inner side of the mixing tank to form fertilizer. Under the support of the conveying box, the second drive motor drives the conveying control plate to move towards the end of the conveying box with the second drive motor through the transmission screw. Then, the guide plate and the guide hole on the conveying control plate are combined to realize that the conveying box guides the fertilizer through the two guide plates.

[0014] 2. The feeding box is vibrated by a vibrating motor to prevent fertilizer from clogging inside. The feeding amount is controlled by adjusting the displacement of the feeding control plate.

The rotation speed of the first drive shaft is lower than that of the second drive shaft. The differential rotation of the first and second drive shafts facilitates synchronous stirring of different amounts of fertilizer. The mixing tank and the mixing tank facilitate segmented mixing of fertilizer, and the fertilizer is stably conveyed by the first and second feeding mechanisms. Attached Figure Description

[0023] like Figure 1 and Figure 2 As shown, the mixing equipment for producing wood chip carbon-based fertilizer according to this utility model includes a segmented mixing mechanism 1, a synchronous stirring mechanism 2 installed inside the segmented mixing mechanism 1, a lower mixing tank 101, an upper mixing tank 102 installed above the lower mixing tank 101, a gearbox 106 fixedly installed between the lower mixing tank 101 and the upper mixing tank 102, a discharge sleeve 103 fixedly installed at the bottom of the lower mixing tank 101, a sealing cover 104 fixedly installed at the upper end of the upper mixing tank 102, and a feed inlet 105 provided on the upper surface of the sealing cover 104.

[0024] As a preferred technical solution in this embodiment, such as Figure 2 , Figure 4 and Figure 5 As shown, a first conveying mechanism 3 and a second conveying mechanism 4 are respectively installed at the bottom of the mixing lower tank 101 and the mixing upper tank 102. The upper and lower ends of the mixing lower tank 101 are connected to the mixing upper tank 102 and the discharge sleeve 103 through the first conveying mechanism 3 and the second conveying mechanism 4 respectively. The first conveying mechanism 3 and the second conveying mechanism 4 both include a conveying box 301. Both conveying boxes 301 are fixedly connected to the mixing lower tank 101. A guide plate 302 is fixedly installed on the inner side of the upper end of the conveying box 301. A conveying control plate 303 is slidably connected to the lower end face of the guide plate 302. The upper end faces of the guide plate 302 and the conveying control plate 303 are provided with two guide holes. The conveying amount is controlled by adjusting the displacement of the conveying control plate 303.

[0025] The guide plate 302 and the conveying control plate 303 are installed in a staggered manner. A transmission screw 304 is installed on the inner side of the bottom end of the conveying control plate 303. The transmission screw 304 is connected to the conveying control plate 303 by a thread. A second transmission motor 305 is fixedly installed at one end of the conveying box 301. Two guide plates 306 are installed on the inner side of the middle part of the conveying box 301. One end of the transmission screw 304 passes through the bottom end of the conveying control plate 303, the conveying box 301, and the two guide plates 306, and is connected to the second transmission motor 305 by a coupling. A vibration motor 307 is fixedly installed at the other end of the conveying box 301. The guide holes on the guide plate 302 and the conveying control plate 303 overlap to guide the fertilizer in the conveying box 301 through the two guide plates 306. At the same time, the vibration motor 307 vibrates the conveying box 301 to prevent the fertilizer from clogging inside the conveying box 301.

[0026] As a preferred technical solution in this embodiment, such as Figures 2 to 4 As shown, the synchronous stirring mechanism 2 includes a first drive motor 201, which is fixedly connected to the mixing tank 101. The output end of the first drive motor 201 is connected to a first drive shaft 202 via a coupling. Multiple arc-shaped scrapers 203 are fixedly installed on the outer side of the bottom end of the first drive shaft 202. The inner wall of the bottom end of the mixing tank 101 is in close contact with the multiple arc-shaped scrapers 203. Multiple first stirring frames 204 are fixedly installed on the outer side of the middle part of the first drive shaft 202. A second drive shaft 206 is installed above the first drive shaft 202. The first drive shaft 202 and the first... The two drive shafts 206 are rotatably connected to the lower mixing tank 101 and the upper mixing tank 102, respectively. Multiple second stirring frames 205 are fixedly installed on the outside of the second drive shaft 206. The rotation direction of the first drive shaft 202 and the second stirring frame 205 is clockwise. The gearbox 106 is equipped with a planetary gear set. The first drive shaft 202 and the second drive shaft 206 are connected by the planetary gear set. The rotation speed of the first drive shaft 202 is lower than that of the second drive shaft 206. The differential rotation of the first drive shaft 202 and the second drive shaft 206 facilitates the synchronous mixing of different fertilizer amounts.

[0027] Working principle: When preparing carbon-based fertilizer from wood chips, the raw materials are injected into the inner side of the mixing tank 102 through the feed inlet 105. The power is turned on and the first drive motor 201 is started. A planetary gear set is provided inside the gearbox 106. The first drive shaft 202 and the second drive shaft 206 are connected by the planetary gear set. Under the support of the mixing tank 101, the first drive motor 201 drives the second drive shaft 206 to rotate synchronously through the first drive shaft 202 and the planetary gear set. Then, the first drive shaft 202 and the second drive shaft 206 synchronously drive the first stirring frame 204, the second stirring frame 205 and multiple arc-shaped scrapers 203 to rotate clockwise. In this way, the multiple second stirring frames 205 can perform pre-stirring operation on the inner side of the mixing tank 102 to form fertilizer.

[0028] After pre-mixing, the first conveying mechanism 3 is controlled to facilitate the delivery of fertilizer to the inner side of the mixing tank 101. Specifically, the upper surfaces of the guide plate 302 and the conveying control plate 303 are each provided with two guide holes, and the guide plate 302 and the conveying control plate 303 are installed in a staggered manner. The second drive motor 305 is started, so that the second drive motor 305, under the support of the conveying box 301, drives the conveying control plate 303 to move towards the end of the conveying box 301 with the second drive motor 305 through the transmission screw 304. Then, the guide holes on the guide plate 302 and the conveying control plate 303 are overlapped, so that the conveying box 301 guides the fertilizer through the two guide plates 306. At the same time, the vibration motor 307 vibrates the conveying box 301 to prevent the fertilizer from being blocked inside the conveying box 301.

[0029] The amount of material conveyed is controlled by adjusting the displacement of the conveying control plate 303. The fertilizer is further stirred by multiple first stirring racks 204 inside the mixing tank 101 and scraped and gathered by multiple arc-shaped scrapers 203, so that the fertilizer can be output through the discharge sleeve 103 by the second conveying mechanism 4. The rotation speed of the first drive shaft 202 is lower than that of the second drive shaft 206. The differential rotation of the first drive shaft 202 and the second drive shaft 206 facilitates the synchronous stirring of different amounts of fertilizer. The mixing tank 101 and the mixing tank 102 facilitate the segmented mixing operation of fertilizer and the stable conveying of fertilizer by the first conveying mechanism 3 and the second conveying mechanism 4.

[0030] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
