Description

Technical Field

[0001] This application relates to the field of baling machine technology, and in particular to a material pressing and guiding device and a baling machine. Background Technology

[0002] Currently, the commonly used straw and forage harvesting equipment in my country are square balers and round balers. However, due to my country's unique planting environment, baling operations are affected by the season and the operating time is relatively short. Therefore, how to improve the efficiency of baling operations during the limited operating season has become an urgent problem for baler manufacturers.

[0003] Pickup efficiency is one of the key factors affecting the overall operating efficiency of balers. Existing balers usually have a pressing and guiding device at the pickup mechanism to guide and compact the picked-up straw, ensuring that the straw can be smoothly fed into the baler's feeding mechanism. However, the existing pressing and guiding devices are not ideal in terms of both guiding and pressing effects, and are prone to leakage and blockage. Utility Model Content

[0004] The purpose of this utility model is to provide a material pressing and guiding device and a bundling machine, so as to avoid material blockage and leakage to a certain extent, improve the material guiding and pressing effect, and thus improve the picking efficiency.

[0005] This utility model provides a pressing and guiding device for use in the picking mechanism of a baler; the pressing and guiding device includes a pressing roller and a guiding roller;

[0006] Both the pressure roller and the guide roller are rotatable. The pressure roller is arranged in parallel at intervals in front of the picking wheel of the picking mechanism, and the guide roller is arranged in parallel at intervals above the picking wheel. Both the pressure roller and the guide roller have multiple teeth circumferentially spaced on their roller surfaces.

[0007] Furthermore, the rotation direction of the pressure roller and the guide roller is a first direction;

[0008] The teeth on the pressure roller and the guide roller are both inclined in a second direction, which is opposite to the first direction.

[0009] Furthermore, both the pressure roller and the guide roller are polygonal rollers, and the teeth are formed on the side edges of the polygonal rollers;

[0010] For any given tooth, the polygonal roller has a side surface connected to the non-working surface of the tooth, a first line connecting the center of the polygonal roller to the vertex of the tooth, and a second line perpendicular to the side surface connecting the center of the polygonal roller to the side surface, the angle between the first line and the second line being an acute angle less than 45°.

[0011] Furthermore, the pressing and guiding device includes a first arm and a second arm, one end of the first arm and the second arm are both mounted on the frame of the baler, and the other end of the first arm and the second arm extend from above the picking wheel to the front of the picking wheel.

[0012] Both ends of the pressure roller and the guide roller are rotatably connected between the first support arm and the second support arm.

[0013] Furthermore, the first arm and the second arm are respectively pivotally connected to the frame of the baler via rotating shafts, and the rotating shafts of the first arm and the second arm are collinear and parallel to the rotating shaft of the pressure roller.

[0014] Furthermore, a connecting rod is provided between the first support arm and the second support arm. The connecting rod is spaced apart between the pressure roller and the guide roller, and the connecting rod is connected to the frame of the baler through a connector.

[0015] Furthermore, the connector is a cable.

[0016] Furthermore, the connector has an elastic element in the middle.

[0017] Furthermore, there are multiple connectors, and the multiple connectors are spaced apart along the length direction of the connecting rod.

[0018] This utility model also provides a baling machine, including the material pressing and guiding device described in any of the above claims.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] The material pressing and guiding device provided by this utility model includes a pressing roller and a guiding roller. Both the pressing roller and the guiding roller can rotate around their own axis. The pressing roller is arranged parallel to each other in front of the picking wheel of the picking mechanism, and the guiding roller is arranged parallel to each other above the picking wheel of the picking mechanism. Multiple teeth are circumferentially spaced on the roller surfaces of both the pressing roller and the guiding roller. In practical applications, as the picking wheel rotates, the teeth on the picking wheel can pick up the scattered hay on the ground and transport it backward. During the transport process, the hay first passes between the picking mechanism and the pressing roller, and then between the picking mechanism and the guiding roller. The pressing roller initially compacts the hay, and the guiding roller guides the transport direction of the hay, allowing it to smoothly enter the feeding mechanism of the baler.

[0021] When the forage passes through the pressure roller and guide roller, the pressure roller and guide roller are subjected to force and rotate. In this embodiment, both the pressure roller and guide roller are provided with teeth on their roller surfaces. When the pressure roller and guide roller rotate, they can enhance the gripping force on the forage through their own teeth, thereby preventing material leakage. At the same time, using the guide roller with teeth as a guiding structure can effectively prevent blockage at the guiding structure during the forage conveying process. This improves the pressing and guiding effect of the pressure and guiding device, thereby increasing the picking efficiency.

[0022] This utility model also provides a baler, including the aforementioned pressing and guiding device, thus the baler also has the beneficial effects of the pressing and guiding device. Attached Figure Description

[0034] The following reference Figures 1 to 3 This application describes a pressing and guiding device and a baling machine according to some embodiments thereof.

[0035] This application provides a material pressing and guiding device for use at the picking mechanism of a baler, to cooperate with the picking mechanism in feeding the picked-up straw into the feeding mechanism of the baler; such as Figure 1 As shown, the pressing and guiding device includes a pressing roller 1 and a guiding roller 2. Both the pressing roller 1 and the guiding roller 2 can rotate around their own axes. The pressing roller 1 is arranged parallel to each other in front of the picking wheel of the picking mechanism, and the guiding roller 2 is arranged parallel to each other above the picking wheel of the picking mechanism. Multiple rows of teeth 3 are circumferentially spaced on the roller surfaces of both the pressing roller 1 and the guiding roller 2. It should be noted that the front-back direction and the up-down direction referred to in this application are based on the front-back direction and the up-down direction of the baler's vehicle coordinate system when the pressing and guiding device is installed on the baler.

[0036] In practical applications, as the picking wheel rotates, the spring teeth on the picking wheel can pick up the straw scattered on the ground and transport it backward. During the transport process, the straw will first pass between the picking mechanism and the pressing roller 1, and then between the picking mechanism and the guide roller 2. The pressing roller 1 is used to initially compact the straw, and then the guide roller 2 is used to guide the transport direction of the straw, so that the straw can smoothly enter the feeding mechanism of the baler.

[0037] When the forage passes through the pressure roller 1 and guide roller 2, the pressure roller 1 and guide roller 2 are subjected to force and rotate. In this embodiment, both the pressure roller 1 and guide roller 2 are provided with teeth 3 on their roller surfaces. When the pressure roller and guide roller 2 rotate, both the pressure roller 1 and guide roller 2 can enhance their gripping force on the forage through their own teeth 3, thereby preventing material leakage. At the same time, using the guide roller 2 with teeth 3 as a guiding structure can effectively prevent blockage at the guiding structure during the forage conveying process. Thus, the pressing and guiding effects of the pressure and guiding device are improved, thereby increasing the picking efficiency.

[0038] In this embodiment, preferably, the pressure roller 1 and the guide roller 2 rotate under force as the forage passes by, and both rotate in the first direction, specifically opposite to the rotation direction of the picking wheel; simultaneously, the teeth 3 on the pressure roller 1 and the guide roller 2 are inclined in the second direction, which is opposite to the first direction; that is, as Figure 3 As shown, when both the pressure roller 1 and the guide roller 2 rotate clockwise, the teeth 3 on both have a tendency to tilt in the counterclockwise direction, thereby improving the material gripping effect and avoiding material leakage.

[0039] In this embodiment, preferably, as follows: Figure 3 As shown, both the pressure roller 1 and the guide roller 2 are polygonal rollers, such as hexagonal rollers; each side edge of the polygonal roller has a tooth 3. For any tooth 3, the tooth 3 has a working surface and a non-working surface 31, that is, the side surface of the tooth 3 facing the rotation direction of the polygonal roller is the working surface, and the other side surface is the non-working surface 31; the polygonal roller has a side surface connected to the non-working surface 31 of the tooth 3. A perpendicular line is drawn from the center of the polygonal roller to this side surface, denoted as the second connecting line 33, and a line is drawn connecting the center of the polygonal roller and the vertex of the tooth 3, denoted as the first connecting line 32; in this embodiment, the included angle α between the first connecting line 32 and the second connecting line 33 is an acute angle less than 45°. This allows the tooth 3 to provide a good material gripping effect and avoid material leakage.

[0040] In one embodiment of this application, preferably, as shown below, Figure 1 and Figure 2As shown, the pressing and guiding device also includes a first arm 4 and a second arm 8. One end of both the first arm 4 and the second arm 8 is mounted on the frame of the baler, and the other end extends from above the pick-up wheel to the front of the pick-up wheel. The pressing roller 1 and the guiding roller 2 are both located between the first arm 4 and the second arm 8. The first arm 4 is rotatably connected to one end of the pressing roller 1 and the guiding roller 2 via a first bearing, and the second arm 8 is rotatably connected to the other end of the pressing roller 1 and the guiding roller 2 via a second bearing. Thus, the first arm 4 and the second arm 8 are used to support and install the pressing roller 1 and the guiding roller 2.

[0041] In this embodiment, preferably, as follows: Figure 1 As shown, the first arm 4 and the second arm 8 are pivotally connected to the frame of the baler via rotating shafts. The rotating shafts of the first arm 4 and the second arm 8 are collinear and parallel to the rotating shaft of the pressure roller 1. This allows the first arm 4 and the second arm 8 to drive the guide roller 2 and the pressure roller 1 to rotate up and down relative to the picking wheel below, thereby adjusting the distance between the guide roller 2 and the picking wheel, and between the pressure roller 1 and the picking wheel. This allows the guide roller 2 to provide appropriate pressure to the straw, and allows the straw to pass smoothly between the guide roller 2 and the picking wheel, and between the pressure roller 1 and the picking wheel.

[0042] In this embodiment, preferably, as follows: Figure 1 and Figure 2 As shown, a connecting rod 6 is connected between the first arm 4 and the second arm 8, and the connecting rod 6 is located between the pressure roller 1 and the guide roller 2. The connecting rod 6 is connected to the frame of the baler through the connecting piece 5, thereby improving the installation stability of the first arm 4, the second arm 8, the pressure roller 1 and the guide roller 2.

[0043] In this embodiment, preferably, as follows: Figure 1 and Figure 2 As shown, the connector 5 is a flexible and adaptable cable, which allows the pressure roller 1 to rise and fall adaptively according to the condition of the straw, so as to provide good pressure to the straw without jamming or leakage.

[0044] In this embodiment, preferably, as follows: Figure 2 As shown, the connector 5 has an elastic element 7 in the middle, meaning the connector 5 is divided into two sections, which are connected by the elastic element 7. The elastic force of the elastic element 7 allows the first arm 4 and the second arm 8 to move up and down, and also allows the pressure roller 1 to adaptively move up and down according to the condition of the forage, ensuring good pressure on the forage without jamming or leakage.

[0045] In this embodiment, preferably, the connecting rod 6 is connected to the frame of the baler through multiple connectors 5, and the connection points of the multiple connectors 5 and the connecting rod 6 are spaced apart along the length of the connecting rod 6, thereby ensuring good connection stability.

[0046] This application also provides a baling machine, including the material pressing and guiding device of any of the above embodiments.

[0047] In this embodiment, the baler includes a pressing and guiding device, and therefore the baler has all the beneficial effects of the pressing and guiding device, which will not be described in detail here.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
