Description

Technical Field

[0001] This utility model belongs to the field of nut processing, specifically a crushing device for producing crushed nuts. Background Technology

[0002] Nuts generally refer to seeds or fruits with hard shells. They are rich in nutrients and are a favorite snack for many people. There are many types of nuts, including walnuts, almonds, cashews, pistachios, hazelnuts, pine nuts, ginkgo nuts, etc.

[0003] During nut processing, nuts are broken into smaller particles to facilitate subsequent processing operations such as mixing, seasoning, and packaging. This process is widely used in the food processing industry, particularly in nut processing, catering, and baking. However, a single crushing operation is often insufficient to completely break down the nuts, requiring further screening and crushing of the crushed product. This not only reduces the production efficiency of nut crushing but also increases labor and machinery operating costs.

[0004] In summary, this utility model provides a crushing device for producing crushed nuts to solve the above problems. Utility Model Content

[0021] To better understand the technical content of this utility model, specific embodiments are described below in conjunction with the accompanying drawings. Various aspects of this utility model are described in this disclosure with reference to the accompanying drawings, which illustrate numerous illustrative embodiments. The embodiments of this disclosure are not necessarily defined to include all aspects of this utility model. It should be understood that the various concepts and embodiments described above, as well as those described in more detail below, can be implemented in any of many ways, because the concepts and embodiments disclosed in this utility model are not limited to any particular implementation. Furthermore, some aspects of this utility model can be used alone or in any suitable combination with other aspects disclosed in this utility model. Example 1

[0022] like Figure 1-4 As shown, this is the first embodiment of the present invention. This embodiment provides a crushing device for producing crushed nuts, including an outer box 1, a feeding hopper 2 provided on the back of the outer box 1, a support frame 3 fixedly connected to the bottom of the outer box 1, a receiving box 4 detachably connected to the inner cavity of the support frame 3, a support plate 5 provided at the rear end of the inner cavity of the outer box 1, the front end of the feeding hopper 2 penetrating into the inner cavity of the outer box 1 and fixedly connected to the support plate 5, and a crushing mechanism 6 provided on the front of the support plate 5.

[0023] The crushing mechanism 6 includes a crushing box 601, which is located on the front of the support plate 5 and is movably connected to the support plate 5 through bearings. The surface of the crushing box 601 is provided with screen holes 602. The inner cavity of the crushing box 601 is fixedly connected with a guide plate 607. Crushing rollers 603 are provided on both sides of the inner cavity of the crushing box 601.

[0024] like Figure 1-4 As shown, the outer box 1 provides space for the crushing of nuts and kernels, preventing particles from splashing out during the crushing process and thus reducing raw material waste. The feeding hopper 2 facilitates the addition of nuts and kernels into the crushing mechanism 6. After the nuts and kernels are added to the crushing mechanism 6, the crushing mechanism 6 can crush them into smaller particles. At the same time, the crushing mechanism 6 can screen the crushed particles. Large particles cannot be screened out and can continue to be crushed inside the crushing mechanism 6 until the volume meets the standard, thus solving the crushing problem in one go and saving time and operating costs. The receiving box 4 is used to place the support plate 5, which is used to store the crushed particles for centralized collection. Example 2

[0025] Reference Figure 2-4 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0026] In this embodiment, a first motor 604 is fixedly connected to the front of the outer casing 1. The output shaft of the first motor 604 passes through the inner cavity of the outer casing 1 and is connected to the crushing box 601 in a transmission manner.

[0027] The rear end of the crushing roller 603 extends through to the back of the support plate 5 and is fixedly connected to a gear 605. The two gears 605 mesh, and the rear end of the crushing roller 603 is movably connected to the inner wall of the support plate 5 through a bearing.

[0028] A second motor 606 is fixedly connected to the back of the inner cavity of the outer casing 1, and the output shaft of the second motor 606 is connected to the back of the left gear 605 for transmission.

[0029] like Figure 2-4 As shown, the second motor 606 drives the left gear 605 to rotate. Since the two gears 605 mesh, they can drive the two crushing rollers 603 to rotate simultaneously. When the two crushing rollers 603 rotate, they can crush the nuts and kernels. The first motor 604 drives the crushing box 601 to rotate. After crushing, smaller nut and kernel particles fall through the sieve holes 602 into the receiving box 4, where they are stored by the support plate 5. Larger particles cannot be screened out and will gradually rise with the rotation of the crushing box 601 under the support of the guide plate 607 until they fall back between the two crushing rollers 603 for re-crushing until they are large enough to be screened out by the sieve holes 602. Example 3

[0030] Reference Figure 3 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0031] In this embodiment, fixing plates 7 are fixedly connected to both sides of the support plate 5, and the side of the fixing plate 7 away from the support plate 5 is fixedly connected to the inner wall of the outer box 1.

[0032] The lower end of the front of the outer box 1 is movably connected to the limit plate 8 via a movable pin, and the front and rear ends of both sides of the outer box 1 are fixedly connected to the support plates.

[0033] like Figure 3 As shown, the fixing plate 7 is used to fix the support plate 5 and improve the stability of the support plate 5 during use. The limiting plate 8 is used to limit the support plate 5 and prevent the vibration generated during the operation of the device from causing the support plate 5 to slide out of the inside of the receiving box 4.

[0034] In use, the first motor 604 and the second motor 606 are started first, and nuts are added into the crushing box 601 through the feeding hopper 2. The first motor 604 drives the crushing box 601 to rotate, and the second motor 606 drives the left gear 605 to rotate. Since the two gears 605 mesh, they can drive the two crushing rollers 603 to rotate simultaneously. When the two crushing rollers 603 rotate, they can crush the nuts. After crushing, smaller nut particles fall into the receiving box 4 through the screen holes 602 and are stored by the support plate 5. Larger particles cannot be screened out and will gradually rise with the rotation of the crushing box 601 under the support of the guide plate 607 until they fall back between the two crushing rollers 603 for re-crushing until they are large enough to be screened out through the screen holes 602. After crushing, the support plate 5 can be pulled out from the receiving box 4 by removing the limiting plate 8.

The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. The control method is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art and is common knowledge in the field. Since this application is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail in this application.

[0036] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Those skilled in the art to which this invention pertains can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of this invention shall be determined by the claims.
