Description

Technical Field

[0001] This invention relates to the field of corn processing, and in particular to a corn pressing device. Background Technology

[0002] In traditional pneumatic corn peeling machines, the structure used to press the corn down consists of a set of rubber wheels mounted between two circular saw blades. When the corn moves laterally between the two blades with the machine, it comes into contact with the rubber wheels, which are then driven to rotate, using gravity to press down the corn and complete the cutting.

[0003] In the prior art, there is a Chinese utility model application, CN202120795777.7, filed on April 19, 2021, entitled "An Air-blown Fresh Corn Peeling Machine". The coarse cutting mechanism is located at one end of the support frame and on both sides of the feeding mechanism. The upper end of the pressing roller is connected to the inner surface of the support frame, and the lower end is located between the coarse cutting mechanisms. The feeding mechanism conveys the corn cobs in a single row. When they enter the support frame, the pressing roller at the front contacts the surface of the corn cob, appropriately squeezing it to ensure more even distribution when it enters the root and tip assemblies. The pressing roller consists of at least two rotating rollers, similar to tire rollers, which facilitates contact with the corn cob, resulting in high friction and good pressing effect.

[0004] However, in actual work, cylindrical parts such as rubber wheels and pressure rollers have a small contact area with the corn, making it very easy for the corn to shift laterally or fly away. In severe cases, the corn may move along the axis to the cutting mechanism at the root or tip of the corn, which can damage the circular saw blade used to cut the corn.

[0005] Therefore, there is an urgent need for a pressing device that can increase the contact area with the corn to ensure that the corn does not easily move along its axis. Summary of the Invention

[0006] The purpose of this invention is to provide a compaction device that increases the contact area with corn.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A corn compaction device includes a main chain forming a chain drive connected to a frame, a drive sprocket, and a driven sprocket assembly including multiple driven sprockets;

[0009] The enclosed main chain meshes with the driving sprocket and a plurality of driven sprockets respectively;

[0010] The drive sprocket rotates under the drive of the power mechanism and drives the main chain transmission;

[0011] The driven sprocket assembly includes a first driven sprocket and a second driven sprocket located at the same height. The main chain located between the first driven sprocket and the second driven sprocket is configured as a pressure chain. The pressure chain is located on the lower part of the main chain and is in a slack state, and can be concave under the action of gravity.

[0012] A buffer layer is provided on the outer surface of the main chain;

[0013] The pressing chain presses down the corn located below the pressing device. The axial direction of the corn is perpendicular to the transmission direction of the pressing chain, and the transmission direction of the corn is parallel to the transmission direction of the pressing chain.

[0014] Furthermore, the outer contour of the frame is triangular, and the driving sprocket, the first driven sprocket, and the second driven sprocket are rotatably connected to the three corners of the frame, with the driving sprocket located above the line connecting the first driven sprocket and the second driven sprocket.

[0015] Furthermore, the driving sprocket, the first driven sprocket, and the second driven sprocket are arranged in an isosceles triangle.

[0016] Furthermore, the driving sprocket, the first driven sprocket, and the second driven sprocket are all double-row sprockets.

[0017] Furthermore, a first double-row chain guide rail is fixed between the driving sprocket and the first driven sprocket on the outer surface of the frame, and a second double-row chain guide rail is fixed between the driving sprocket and the second driven sprocket.

[0018] The main chain is matched with the first double-row chain guide and the second double-row chain guide, respectively.

[0019] Furthermore, the outer surface of the buffer layer is arrayed with multiple grooves, the length direction of which is parallel to the axial direction of the corn.

[0020] Furthermore, the buffer layer consists of multiple polyurethane blocks, with adjacent polyurethane blocks spaced apart to form the groove.

[0021] Furthermore, the power mechanism includes a power wheel fixed coaxially with the drive sprocket, and the motor drives the power wheel to rotate through the transmission mechanism, thereby causing the drive sprocket to rotate.

[0022] Furthermore, the main chain is made of stainless steel.

[0023] Furthermore, the conveying speed of the corn is equal to the transmission speed of the pressing chain.

[0024] The corn compaction device provided by the present invention, as described above, has the following beneficial effects:

[0025] The corn pressing device of this invention is a tracked type, similar in principle to tank tracks. During operation, the drive sprocket on the pressing device rotates with the power mechanism. The drive sprocket and driven sprocket form a support wheel system, supporting the rotation of the main chain. The length of the pressing chain is greater than the distance between the first driven sprocket and the second driven sprocket, and there is a downward gap between the pressing chain and the line connecting the centers of the first and second driven sprockets. In use, the natural curvature of the pressing chain's sag position is used to press the corn, and the conveying speed of the pressing chain and the corn is kept as consistent as possible. The pressing chain itself is strip-shaped, more flexible than traditional pressing rollers, and has greater flexibility in contact with the corn. The length direction of the pressing chain is consistent with the forward direction of the corn, allowing the pressing chain to press 2-3 ears of corn at a time, while traditional pressing rollers can only press one ear of corn at a time, thus improving pressing efficiency. The pressing chain can deform and cover the top surface of the corn, while traditional pressing rollers make line contact with the corn using an arc-to-arc design; this invention increases the pressing area.

[0026] Polyurethane pressure blocks are installed on the main chain. The flexible polyurethane pressure blocks have several transverse grooves, which prevents the main chain from damaging the corn and increases the friction between the main chain and the corn, preventing the corn from shifting laterally and greatly ensuring cutting safety.

[0027] Because the main chain is made of stainless steel, it avoids corrosion of the main chain and contamination of the corn caused by corn residue adhering to it. Attached Figure Description

[0038] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0039] like Figure 1-7 The corn compaction device shown includes a main chain 3 forming a chain drive mounted on a frame 2, a drive sprocket 1, and a driven sprocket group including multiple driven sprockets.

[0040] Among them, frame 2 serves as the mounting base for chain drive, and drive sprocket 1 and multiple driven sprockets are rotatably connected to frame 2.

[0041] The drive sprocket 1 and multiple driven sprockets together form a support sprocket system supporting the main chain 3. The enclosed main chain 3 meshes with the drive sprocket 1 and the multiple driven sprockets respectively, and is fitted over the drive sprocket 1 and the multiple driven sprockets. The drive sprocket 1 rotates under the drive of the power mechanism, driving the main chain 3 to rotate. The main chain 3 is preferably a double-pitch chain.

[0042] The driven sprocket assembly includes a first driven sprocket 4 and a second driven sprocket 5 located at the same height. The first driven sprocket 4 and the second driven sprocket 5 are the two lowest driven sprockets in the driven sprocket assembly. The main chain 3 located below the first driven sprocket 4 and below the second driven sprocket 5 is configured as a pressure chain 31. The pressure chain 31 is located on the lower part of the main chain 3 and is in a slack state. When there is no pressure on the corn, it can form a concave arc shape under the action of gravity. That is, the length of the pressure chain is greater than the distance between the first driven sprocket and the second driven sprocket, and there is a downward gap between the pressure chain and the line connecting the center of the first driven sprocket and the center of the second driven sprocket. Along the length of the pressure chain, the middle position of the pressure chain is low and downward, and the two ends of the pressure chain are upward. Preferably, the first driven sprocket 4 and the second driven sprocket 5 are the same size.

[0043] The number of driven sprockets in the driven sprocket assembly is not specified, but the minimum requirement is two driven sprockets: a first driven sprocket 4 and a second driven sprocket 5. The total number can also be three, four, etc. The function of the driven sprocket assembly and the driving sprocket is to output a section of the press chain from the main chain 3. However, from the perspective of simplifying the structure, it is preferable that the driven sprocket assembly includes a first driven sprocket 4 and a second driven sprocket 5 located at the same height. This article schematically describes a driven sprocket assembly consisting of two driven sprockets: a first driven sprocket 4 and a second driven sprocket 5.

[0044] The outer surface of the main chain 3 is provided with a buffer layer 30; in this way, the main chain 3 contacts the corn through the buffer layer. The buffer layer is made of soft material, which prevents the main chain 3 from directly scratching the surface of the corn.

[0045] In use, the pressing chain 31 presses the corn located below the pressing device. The axial direction of the corn is perpendicular to the transmission direction of the pressing chain 31, that is, the axial direction of the corn is along the width direction of the pressing chain. The transmission direction of a row of corn is parallel to the transmission direction of the pressing chain 31, that is, the corn is transmitted along the length direction of the pressing chain.

[0046] As a row of corn or a corn pallet passes over the pressing chain 31, the gap between the pressing chain 31 and the corn gradually decreases until most of the pressing chain 31 can adhere to the top surface of the corn, and the pressing chain 31 deforms to cover the top surface of the corn. After the corn is cut, the gap between the pressing chain 31 and the corn gradually increases until they separate. Figure 2 As shown, two corn cobs are being pressed down under the pressing chain 31.

[0047] Specifically, the outer contour of the frame 2 is triangular. The drive sprocket 1, the first driven sprocket 4, and the second driven sprocket 5 are rotatably connected to the three corners of the frame 2, with the drive sprocket 1 located above the line connecting the first driven sprocket 4 and the second driven sprocket 5, i.e., at the apex. The frame 2 includes two opposing triangular plates, which are fixedly connected. Three rotating shafts are rotatably connected to the three corners of the two triangular plates, and these three shafts are fixedly connected to the drive sprocket 1, the first driven sprocket 4, and the second driven sprocket 5, respectively. The two ends of each shaft are rotatably connected to the corresponding two triangular plates. Preferably, the main chain 3 is located outside the frame 2 and surrounds the frame 2.

[0048] More preferably, the driving sprocket 1, the first driven sprocket 4, and the second driven sprocket 5 are arranged in an isosceles triangle. The driving sprocket 1 is located above the corresponding position of the bisection of the line connecting the center of the first driven sprocket 4 and the center of the second driven sprocket 5, with the center of the driving sprocket 1 forming the vertex of the isosceles triangle. This chain drive structure is more symmetrical and stable.

[0049] Preferably, the driving sprocket 1, the first driven sprocket 4, and the second driven sprocket 5 are all double-row sprockets. The corresponding main chain has a chain structure that matches the double-row sprockets, with two rows of rollers that mesh with the double-row sprockets. The width of the double-row sprockets is wider than that of a single-row sprocket, and it has two support points in the width direction to support the main chain 3, which has the advantage of improving the running stability of the main chain 3.

[0050] Specifically, a first double-row chain guide rail is fixed between the driving sprocket 1 and the first driven sprocket 4 on the outer surface of the frame 2, and a second double-row chain guide rail is fixed between the driving sprocket 1 and the second driven sprocket 5. The main chain 3 is matched with the first and second double-row chain guide rails respectively. The first and second double-row chain guide rails are preferably T-shaped double-row chain guide rails. The first and second double-row chain guide rails are fixed on the outer surface of the triangular frame 2 and guide the main chain 2. The main chain 3 passes sequentially through the driving sprocket 1, the first double-row chain guide rail, the first driven sprocket 4, the second driven sprocket 5, the second double-row chain guide rail, and returns to the driving sprocket 1. The main chain 3 is preferably a double-row chain.

[0051] Preferably, the outer surface of the buffer layer 30 has multiple grooves arranged in an array. The length direction of the grooves is parallel to the axial direction of the corn, i.e., along the width direction of the chain. This prevents the main chain 3 from damaging the corn and increases the friction between it and the corn, preventing lateral displacement of the corn and greatly ensuring cutting safety. More specifically, the buffer layer consists of multiple polyurethane blocks 32, with adjacent polyurethane blocks 32 spaced apart to form grooves. This structure is convenient to install, cost-effective, and utilizes the high performance of polyurethane material.

[0052] Preferably, the power mechanism includes a power wheel 71 coaxially fixed with the drive sprocket 1. A motor drives the power wheel 71 to rotate via a transmission mechanism, causing the drive sprocket 1 to rotate. A drive shaft is rotatably connected to the frame 2, and the drive sprocket 1 and the power wheel 71 are sequentially fixedly connected axially to the drive shaft. The motor is mounted on the frame, or on an air-blown corn peeling machine. The motor transmits power to the power wheel 71 via the transmission mechanism, and the rotation of the power wheel 71 drives the drive sprocket 1 to rotate synchronously. The transmission mechanism can be a fixed wheel that rotates synchronously with the motor's output shaft, with a belt connecting the fixed wheel and the power wheel 71. The transmission mechanism is existing technology and will not be described in detail here.

[0053] Preferably, the main chain 3 is made of stainless steel. This prevents corn contamination caused by corrosion of the main chain after corn residue adheres to it.

[0054] Preferably, the corn is conveyed at the same speed as the pressing chain. The corn and the pressing chain move synchronously, avoiding the risk of the corn being caught in the chain due to asynchrony.

[0055] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
