AI Technical Summary
Existing wood chip mixers cannot effectively mix wood chips, and the integrity of the sample is easily damaged during the mixing process.
A wood chip mixer was designed, which uses a motor-driven spindle to drive mixing flaps. The flaps are evenly distributed radially along the mixing disc to reduce the internal forces between the wood chips and reduce damage.
This method achieves uniform mixing of wood chips, reduces sample damage, and meets the requirements for wood chip sampling.

Abstract
Description
Technical Field
[0001] This utility model relates to wood chip sampling equipment, and in particular to a mixer used in wood chip sampling, belonging to the technical field of wood chip sampling machinery and equipment. Background Technology
[0002] In the papermaking industry, wood chips need to be sampled. After sampling, the samples obtained from multiple sampling points need to be mixed and then reduced in size. There are many material mixers on the market, but after testing, they cannot be used for mixing wood chips. The main reason is that wood chips have very poor fluidity and their unevenness causes a lot of internal force (resistance) during the mixing process. Mixing requires a lot of power, but high power will produce another negative problem: the wood chips will be severely damaged during the mixing process, which will destroy the integrity of the sample. Therefore, in view of the above problems in wood chip sampling, a mixer that can meet the requirements needs to be designed for wood chips. Summary of the Invention
[0003] The purpose of this invention is to provide a mixer for wood chip sampling.
[0004] To achieve the purpose of this utility model, the following technical solution is adopted: a wood chip mixer includes a receiving hopper, a motor is fixedly installed on the side wall of the receiving hopper, a shaft hole is opened on the side of the receiving hopper, a sealing sleeve is fixedly connected to the shaft hole, a main shaft is fixedly connected to the output shaft of the motor, the main shaft is horizontal, the main shaft passes through the shaft hole and the sealing sleeve and extends into the receiving hopper, the shaft sleeve is fixedly connected to the main shaft inside the receiving hopper, the shaft sleeve is located at the center of the mixing disk, and at least four mixing flaps are radially distributed along the mixing disk, the mixing flaps are evenly distributed around the circumference of the mixing disk.
[0005] Furthermore, the mixing flaps consist of six sections.
[0006] Furthermore, a screw hole is provided on the bushing, and a locking hole is provided on the main shaft at the position corresponding to the screw hole. A locking bolt is screwed into the screw hole, and after the locking bolt is screwed into the screw hole, it is pressed into the locking hole. A locking nut is screwed onto the locking bolt.
[0007] Furthermore, the receiving hopper has a right-angled trapezoidal cross-section along the main shaft, the mixing flap is close to the right-angled side of the trapezoid, and the motor is fixedly connected to the hypotenuse of the trapezoid.
[0008] The positive and beneficial technical effects of this utility model are as follows: This mixer can meet the requirements of mixing wood chip samples, which will be explained in detail with specific implementation methods. Attached Figure Description
[0009] Figure 1 This is a schematic diagram of the axial cross-section along the main axis of this utility model.
[0010] Figure 2 yes Figure 1 A schematic diagram of the cross-section along the AA direction. Detailed Implementation
[0011] To more fully explain the implementation of this utility model, implementation examples are provided. These implementation examples are merely illustrative of this utility model and do not limit its scope.
[0012] The present invention will be further explained in detail with reference to the accompanying drawings, in which the following references are made: 1: receiving hopper; 2: motor; 3: main shaft; 4: sealing sleeve; 6: bushing; 7: locking bolt; 8: locking nut; 9: mixing disc; 10: mixing flap.
[0013] As shown in the attached figure, a wood chip mixer includes a receiving hopper 1. A motor 2 is fixedly installed on the side wall of the receiving hopper 1. A shaft hole is opened on the side of the receiving hopper, and a sealing sleeve 4 is fixedly connected to the shaft hole. A main shaft 3 is fixedly connected to the output shaft of the motor. The main shaft is horizontal and extends into the receiving hopper through the shaft hole and the sealing sleeve. A bushing 6 is fixedly connected to the main shaft inside the receiving hopper. In this embodiment, a screw hole is opened on the bushing, and a locking hole is opened on the main shaft at the position corresponding to the screw hole. A locking bolt 7 is screwed into the screw hole and pressed into the locking hole. A locking nut 7 is screwed onto the locking bolt to prevent the locking bolt from loosening. The bushing is located at the center of the mixing disc 8. At least four mixing flaps 9 are distributed radially along the mixing disc. The mixing flaps are evenly distributed around the circumference of the mixing disc. In this embodiment, there are six mixing flaps. In this embodiment, the axial cross-section of the receiving hopper along the main shaft is a right-angled trapezoid, with the mixing flap close to the right-angled side of the trapezoid, and the motor fixedly connected to the hypotenuse of the trapezoid. This facilitates a more even distribution of wood chips within the local space formed by the adjacent mixing flaps. The discharge of this mixer can be achieved by separating the bottom and sides of the receiving hopper; for example, the bottom can be fitted with a movable gate valve, allowing discharge upon opening.
[0014] This mixer is divided into multiple local spaces by a mixing flap. When the material is received in the hopper, the motor rotates to distribute the wood chips into multiple local spaces, reducing the internal forces caused by the unevenness between the wood chips and sawdust. The rotation achieves the effect of material mixing, while minimizing the damage to the wood chip particles. After testing, this mixer can meet the requirements for wood chip sampling.
[0015] After a detailed description of the embodiments of this utility model, those skilled in the art will clearly understand that various changes and modifications can be made without departing from the scope and spirit of the above-mentioned patent applications. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of this utility model shall fall within the scope of the technical solution of this utility model, and this utility model is not limited to the embodiments of the examples given in the specification.
