[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 This utility model provides a technical solution for a wood fiber nutrient matrix production equipment: A wood fiber nutrient matrix production equipment includes a raw material feeding silo 1. The raw material feeding silo 1 can be, but is not limited to, a solid metering feeding silo design, such as a volumetric metering feeding silo. The raw material (i.e., wood fiber that has undergone high-temperature sterilization and saccharification) in the raw material feeding silo 1 is added via a feeding machine. The high-temperature sterilization and saccharification wood fiber is the pulverized material from forest and fruit branches. This design also includes a belt conveyor 3 located below the raw material feeding silo 1, with one end of the belt conveyor 3 corresponding to the discharge port of the raw material feeding silo 1. A screening machine 2 is installed directly below the raw material feeding hopper 1 to receive the material discharged from the raw material feeding hopper 1. The screening machine 2 is mounted directly above the conveying end of the belt conveyor 3 and located directly below the discharge port of the raw material feeding hopper 1. The bottom of the screening machine 2 is connected to a discharge hopper 21. The material discharged from the discharge hopper 21 falls onto the belt conveyor 3. During use, wood fiber raw materials are discharged from the raw material feeding hopper 1 onto the screening machine 2, and the screening machine 2 performs preliminary screening to remove large particles and impurities. The screened material falls from the discharge hopper 21 onto the belt conveyor 3 for transmission.

[0026] A first crusher 4 is installed directly below the discharge end of the belt conveyor 3. A first mixer 6 is installed at the discharge port of the first crusher 4. One end of the first mixer 6 has a mixing inlet 61, and the other end of the first mixer 6 has a mixing outlet 62. The mixing inlet 61 corresponds to the discharge port of the first crusher 4. The material crushed in the first crusher 4 is directly discharged into the mixing inlet 61 through its discharge port. The material discharged from the mixing outlet 62 is transported to the inlet of the second mixer 9 through the first feeder 7. The screened material is transported to the first crusher 4 for preliminary crushing by the belt conveyor 3, and then transported to the first mixer 6. It should be noted that both the first crusher 4 and the second crusher 11 are axial flow crushers.

[0027] The first mixer 6 is also equipped with a liquid additive adding mechanism 5 at the mixing inlet 61. The liquid additive adding mechanism 5 includes mounting plates 51 symmetrically installed on both sides of the mixing inlet 61. Each mounting plate 51 has multiple feeding nozzles 52 distributed on it. A manifold 53 is installed on the rear side of each of the two mounting plates 51. The multiple feeding nozzles 52 are connected to the manifold 53 through branch pipes. The other ends of the two manifolds 53 are connected to a main liquid delivery pipe 54. The first mixer 6 is also equipped with a liquid storage tank 55, which stores a mixture of amino acids and wood vinegar. A conveying pump is installed inside the storage tank 55, and the output end of the conveying pump is connected to the main liquid delivery pipe 54 through a pipeline. When the pre-crushed material enters the first mixer 6, the external control system will control the conveying pump inside the storage tank 55 to work, and transport the liquid auxiliary material inside the storage tank 55 to the two manifolds 53 through the main liquid delivery pipe 54. Then, multiple feeding nozzles 52 on the two mounting plates 51 will spray out the liquid auxiliary material. The feeding nozzles 52 are set at an angle, and the liquid auxiliary material sprayed out will be directly sprayed into the mixing inlet 61 to mix with the material in the first mixer 6 to obtain a preliminary mixture.

[0028] It also includes a second mixer 9, with a first feeder 7 installed between the feed inlet and the mixing outlet 62 of the second mixer 9. A solid auxiliary material feeding hopper 8 is also installed above the feed inlet of the second mixer 9. The solid auxiliary material feeding hopper 8 is mounted on a bracket directly above the feed inlet of the second mixer 9. Two baffle plates 81 are symmetrically arranged at the bottom discharge port of the solid auxiliary material feeding hopper 8. Hinge seats 82 are hinged to both ends of the baffle plates 81 and fixed to the sides of the solid auxiliary material feeding hopper 8. Electric motors are also installed in the middle of both sides of the solid auxiliary material feeding hopper 8. The telescopic ends of the electric push rod 83 are fixed to the middle of one side of the two baffle plates 81 respectively. The two baffle plates 81 are arc-shaped structures corresponding to the discharge port of the solid auxiliary material feeding bin 8. The material initially mixed by the first mixer 6 is transported to the second mixer 9 through the first feeder 7. At the same time, the solid auxiliary material (i.e., the mixture of nitrogen, phosphorus and potassium fertilizer and fruit wood charcoal ash) in the solid auxiliary material feeding bin 8 is added to the feed port of the second mixer 9 and mixed evenly with the initial mixture in the second mixer 9 to obtain the final mixture.

[0029] A second feeder 10 is installed at the discharge port of the second mixer 9. A second crusher 11 is installed below the discharge port of the second feeder 10. The material discharged from the second mixer 9 is conveyed to the feed port of the second crusher 11 through the second feeder 10. The material crushed by the second crusher 11 is discharged through the discharge port onto the belt conveyor and conveyed to the packaging hopper by the belt conveyor. Finally, the mixture is conveyed by the second feeder 10 to the second crusher 11 for crushing and then conveyed to the storage hopper for subsequent metering and packaging.

[0030] The working principle of this utility model is as follows: When in use, the high-temperature sterilized saccharified and pyrolyzed wood fiber is transported to the raw material feeding bin 1 by the feeding machine, and then the wood fiber raw material is discharged to the screening machine 2 for preliminary screening, thereby screening out large particles and impurities. The screened material will fall from the discharge hopper 21 to the belt conveyor 3, and then be transported to the first crusher 4 for preliminary crushing by the belt conveyor 3.

[0031] The pre-crushed material is conveyed to the first mixer 6, where it is mixed and stirred with the liquid additive sprayed by the liquid additive adding mechanism 5 to obtain a preliminary mixture.

[0032] The preliminarily mixed material is discharged from the mixing outlet 62 into the first feeder 7, and then conveyed to the second mixer 9 through the first feeder 7. At the same time, the solid auxiliary material in the solid auxiliary material feeding bin 8 is added to the feed inlet of the second mixer 9 and mixed evenly with the preliminarily mixed material in the second mixer 9 to obtain the final mixture.

[0033] The final mixture is stirred and pushed to the discharge port in the second mixer 9, and then discharged from the discharge port into the second feeder 10. After being conveyed by the second feeder 10 to the second crusher 11 for secondary crushing, it can be conveyed into the guarantee hopper for subsequent metering and packaging.

[0034] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
