A clamping mechanism for a corn stalk and ear separator

Abstract

This utility model discloses a clamping mechanism for a corn stalk-ear separator, belonging to the field of agricultural machinery technology. It includes a mounting shaft with a clamping mechanism mounted on its outer wall; a square roller on the mounting shaft with mounting holes on its outer wall; and a U-shaped clamping groove detachably connected to the square roller, with fastening bolts threaded through the U-shaped groove and engaging with the mounting holes. The U-shaped clamping grooves are arranged in four sets. This utility model, by modifying the traditional clamping mechanism into a structure of a square roller and U-shaped clamping grooves, with four sets of U-shaped clamping grooves detachably mounted on the outer wall of the square roller, each set consisting of two arc-shaped clamping pieces, achieves a structure where eight arc-shaped clamping pieces rotate around each other. This significantly reduces the clamping interval between the arc-shaped clamping pieces, allowing for a smaller area to grip the outer wall of the corn stalk during rotation, resulting in more stable feeding and preventing the corn stalks from clogging the crushing system and affecting the normal operation of the corn stalk-ear separator.

Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and in particular to a clamping mechanism for a corn stalk and ear separator. Background Technology

[0002] Agricultural machinery refers to all kinds of machinery used in crop cultivation and animal husbandry, as well as in the initial processing and handling of agricultural and livestock products. Agricultural machinery includes agricultural power machinery, farmland construction machinery, soil tillage machinery, planting and fertilization machinery, plant protection machinery, farmland irrigation and drainage machinery, crop harvesting machinery, agricultural product processing machinery, livestock machinery, and agricultural transportation machinery, etc.

[0003] In the corn stalk and ear separator, the ear-separating system includes two sets of rotating screw feed shafts. Above the screw feed shafts is a chain-driven ear-separating scraper, and at the end of the screw feed shafts is a synchronously rotating clamping mechanism. As the corn plants enter the ear-separating system, the corn ears are separated at the top by the scraper, and after being clamped by the plant clamping mechanism, they are conveyed downwards and finely crushed by the bottom crushing blades.

[0004] Existing clamping mechanisms typically consist of a round shaft and five arc-shaped clamping plates welded to the outer wall of the shaft. The large spacing between the arc-shaped clamping plates creates large gaps when they rotate to clamp the corn plants, resulting in long time intervals between gripping the outer wall of the plants. This makes it easy to lose grip or miss the softer parts of the plants, leading to uneven conveying of the plants. Consequently, the plants cannot be crushed by the bottom crushing mechanism and may even clog the clamping mechanism, affecting the operation of the device.

[0005] To address the aforementioned issues, a clamping mechanism for a corn stalk-ear separator is proposed. Utility Model Content

[0006] The main purpose of this utility model is to provide a clamping mechanism for a corn stalk and ear separator, which solves the problems mentioned in the background art.

[0007] The objective of this utility model can be achieved by adopting the following technical solution:

[0008] A clamping mechanism for a corn stalk and ear separator includes a mounting shaft, and a clamping mechanism is provided on the outer wall of the mounting shaft;

[0009] The mounting shaft square roller has mounting holes on its outer outer wall;

[0010] The clamping mechanism includes a U-shaped clamping groove that is detachably connected to the square roller, and a fastening bolt is provided through the U-shaped clamping groove to cooperate with the mounting hole;

[0011] The U-shaped clamping grooves are configured in four groups.

[0012] Furthermore, connecting seats are integrally welded to both ends of the square roller, wherein a spiral feed shaft is welded to the upper connecting seat.

[0013] Furthermore, the top of the U-shaped clamping groove is formed with two arc-shaped clamping pieces.

[0014] The beneficial technical effects of this utility model are as follows:

[0015] This invention modifies the traditional clamping mechanism by setting it to a structure of square rollers and U-shaped clamping grooves. The outer wall of the square rollers is detachably equipped with four sets of U-shaped clamping grooves, each set of U-shaped clamping grooves consisting of two arc-shaped clamping pieces, thus achieving a structure in which eight arc-shaped clamping pieces rotate around each other. This greatly reduces the clamping interval between the arc-shaped clamping pieces, and can grab a smaller area of ​​the outer wall of the corn stalks during rotation, resulting in more stable feeding and preventing the corn stalks from clogging the crushing system and affecting the normal operation of the corn stalk and ear separator.

[0021] To enable those skilled in the art to understand the technical solution of this utility model more clearly, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings, but the implementation of this utility model is not limited thereto.

[0022] like Figures 1-3As shown, this embodiment provides a clamping mechanism for a corn stalk and ear separator, including a mounting shaft 1, a clamping mechanism 2 provided on the outer wall of the mounting shaft 1; a square roller 102 on the mounting shaft 1, with mounting holes 102a on the outer wall of the square roller 102; the clamping mechanism 2 includes a U-shaped clamping groove 201 detachably connected to the square roller 102, and a fastening bolt 202 that engages with the mounting holes 102a is provided through the U-shaped clamping groove 201; the U-shaped clamping groove 201 is configured in four sets.

[0023] The two ends of the square roller 102 are integrally welded with connecting seats 101, and the upper connecting seat 101 is welded with a spiral feed shaft 103. The top of the U-shaped clamping groove 201 is formed with two arc-shaped clamping pieces.

[0024] In one embodiment, the design of the square roller 102 facilitates the fixed installation of the U-shaped clamping groove 201, while also reducing the gripping interval between adjacent arc-shaped clamping plates, ensuring that the corn plants can be gripped evenly and avoiding missing the gripping area.

[0025] Working principle of this device: When in use, this device is installed into the corn stalk and ear separator through the connecting seat 101, and the two sets of mounting shafts 1 rotate in opposite directions.

[0026] The corn plants are fed one by one into the spiral feed shaft 103 through the feeding system. The spiral feed shaft 103 conveys the corn plants backward by spiral clamping. The corn ears are scraped off by the scraper mechanism driven by the chain belt above the spiral feed shaft 103. The corn stalks continue to enter between the two sets of U-shaped clamping grooves 201. After being clamped by the rotating U-shaped clamping grooves 201, they are conveyed to the bottom and enter the crushing cutter for fine crushing.

[0027] With the above structure, the clamping method of the four sets of U-shaped clamping grooves 201 and eight arc-shaped clamping plates on the outer wall of the square roller 102 greatly reduces the clamping interval between the arc-shaped clamping plates. When rotating, it can grab a smaller area of ​​the outer wall of the corn stalk, so as to feed more stably and avoid the corn stalk from clogging the crushing system and affecting the normal operation of the corn stalk and ear separator.

[0028] The above are merely further embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope disclosed by this utility model, based on the technical solution and concept of this utility model, shall fall within the protection scope of this utility model.

[0029] All standard parts used in this application can be purchased from the market, and can be customized according to the description and drawings. 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.
