Description

Technical Field

[0001] This utility model relates to the field of grain and oil crushing roller technology, specifically a grain and oil crushing roller that is easy to maintain. Background Technology

[0002] The grain and oil crushing roller is a device used to crush oilseeds. Its main purpose is to pre-treat the oilseeds before oil extraction to improve the oil yield and oil extraction efficiency.

[0003] For example, Chinese Patent CN208407147U (A Toothed Crushing Roller) includes an inner crushing roller. A support frame is fixedly connected to the inner wall of the inner crushing roller. A first ball bearing is fixedly connected to the inner wall of the support frame. A first threaded rod and a second threaded rod are fixedly connected to the inner wall of the first ball bearing. Support blocks are fixedly connected to both sides of the inner wall of the inner crushing roller. This toothed crushing roller, through a first connecting block, allows a second connecting block to move up and down. Simultaneously, a first limiting block limits the movement of the outer crushing roller, facilitating the disassembly and installation of the outer and inner crushing rollers. This effectively solves the problem that currently, toothed crushing rollers require machining, electric grinding, or gas cutting to treat the worn surface after wear. For high-strength surfaces, these methods result in poor treatment effects and prolonged processing time, affecting the crushing operation.

[0004] However, existing grain and oil crushing rollers, which are formed by welding, are inconvenient to disassemble and maintain. They are fixed with a single bolt, and the centrifugal force can easily cause the inner and outer rollers to shake and separate after long-term rotation. Furthermore, it is not easy to install outer rollers of different sizes, and the inner rollers of the corresponding size need to be replaced, resulting in low flexibility and applicability. Therefore, they do not meet the current needs. To address this, we propose a grain and oil crushing roller that is easy to maintain. Utility Model Content

In addition, it is not easy to install outer rollers of different sizes, and it is necessary to replace the inner rollers of the corresponding size, resulting in low flexibility and applicability.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a grain and oil crushing roller that is easy to maintain, comprising: a rotating assembly, an inner roller assembly disposed outside the rotating assembly, an outer roller sleeve disposed outside the inner roller assembly, a first groove disposed on the inner wall of the outer roller sleeve, and multiple first grooves disposed thereon, and the multiple first grooves are distributed in an equidistant array, a fixed seat disposed at both ends of the inner roller assembly, and the rotating assembly is fixed to the inner roller assembly through the fixed seat, an adjusting seat disposed on one side of the fixed seat, and the inner roller assembly is fixed to the outer roller sleeve through the adjusting seat.

[0007] Preferably, the inner roller assembly includes a first inner roller sleeve and a second inner roller sleeve, both of which are hollow inside. Each of the first and second inner roller sleeves has an insertion port at the center of one end surface, and the insertion port passes through the first and second inner roller sleeves. The rotating component is inserted along the insertion port.

[0008] Preferably, the outer walls of the first inner roller sleeve and the second inner roller sleeve are provided with first retaining strips, and multiple first retaining strips are provided, and the first retaining strips are inserted along the first retaining groove.

[0009] Preferably, the inner roller assembly further includes an extension sleeve, which is located between the first inner roller sleeve and the second inner roller sleeve. The other end surface of the first inner roller sleeve is provided with a first connecting post, the other end surface of the second inner roller sleeve is provided with a first connecting slot, one end surface of the extension sleeve is provided with a first extension slot, and the other end surface of the extension sleeve is provided with a first extension post. The first extension post is inserted into the first connecting slot, and the first connecting post is inserted into the interior of the first extension slot.

[0010] Preferably, the rotating assembly includes a first rotating column and a second rotating column, each with a rotating shaft at one end, a second retaining strip on the outer wall of each column, and a second retaining groove on the inner wall of the insertion port, with the second retaining strip inserted along the groove.

[0011] Preferably, one end of the fixed seat is provided with a rotating shaft, and the fixed seat rotates along the rotating shaft. The other end of the fixed seat is provided with a first bolt, and one end of the first bolt passes through the fixed seat and is threadedly connected to the second retaining strip. The surface of the adjusting seat is provided with an adjusting groove, and both ends of the adjusting groove are provided with second bolts. The two ends of the adjusting seat are threadedly fixed to the inner roller assembly and the outer roller sleeve respectively by the second bolts.

[0012] Preferably, the rotating assembly further includes an extension column, one end surface of which is provided with a second extension slot, the other end surface of which is provided with a second extension post, the other end surface of the first rotating column is provided with a second connecting post, the other end surface of the second rotating column is provided with a second connecting slot, and the second connecting post is inserted into the second extension slot.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) This utility model realizes the length adjustment of the inner roller assembly and the rotating assembly by installing and disassembling the extended sleeve and the extended column. It is suitable for outer roller sleeves of different sizes, without the need to use an additional outer roller sleeve of the corresponding size, reducing investment costs and improving flexibility and applicability. The extended column and the extended sleeve can be replaced by plugging and unplugging, which is convenient for disassembly and maintenance. When the rotating assembly and the inner roller assembly are connected, the second locking strip is inserted along the second locking groove to improve the stability of the connection between the rotating assembly and the inner roller assembly and to prevent rotational deviation. When the inner roller assembly and the outer roller sleeve are connected, the first locking strip is inserted along the first locking groove to improve the stability of the connection between the outer roller sleeve and the inner roller assembly. This solves the problems of existing grain and oil crushing rollers that use welding forming method, which are inconvenient to disassemble and maintain the inner and outer rollers. The use of a single bolt fixation method makes it easy for the inner and outer rollers to shake and separate due to centrifugal force after long-term rotation. It is also not easy to install outer rollers of different sizes and requires the replacement of inner rollers of the corresponding size, resulting in low flexibility and applicability.

[0015] (2) By setting adjustment seats at both ends of the inner roller assembly, the second bolt is adjusted along the adjustment groove. The two ends of the adjustment seat are respectively threaded to the inner roller assembly and the outer roller sleeve by the second bolt, so as to fix the inner roller assembly and the outer roller sleeve. By adjusting the position of the second bolt, it is suitable for outer roller sleeves of different sizes, thus improving flexibility. Attached Figure Description
