Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery, specifically to a suspended hopper for a thresher. Background Technology

[0002] A thresher is a common agricultural machine, mainly used for threshing and cleaning crops such as corn, rice and wheat. It has the advantages of high efficiency, saving time and labor, and can greatly reduce the labor intensity of farmers, freeing them from heavy physical labor. Therefore, threshers are widely used in agricultural production.

[0003] Existing threshers typically include a top cover, a threshing bin, a collection bin, and an air separator. The top cover has a feeding port located on top of the threshing bin, used to seal the threshing bin and feed material into it. The hopper is detachably mounted on the top cover and has an inlet and an outlet. The inlet is used to feed crops into the hopper, and the outlet is connected to the feeding port of the top cover, thus feeding material into the threshing bin through the hopper.

[0004] In existing technologies, the installation of hoppers typically requires one installer to lift the hopper and align its discharge end with the feed port on the top cover, followed by another installer installing the bolts to secure the hopper to the top cover. This installation method is time-consuming, labor-intensive, and inconvenient. Furthermore, the installation process requires installers to constantly adjust the hopper's position to align it with the bolt holes on the top cover, necessitating prolonged periods of lifting the hopper and increasing the workload for the installers.

[0005] To address these technical problems, a suspended hopper for a thresher is proposed. Utility Model Content

[0006] This invention provides a suspended hopper for a thresher to solve the problems of existing hoppers requiring two people to install, which are inconvenient and labor-intensive.

[0007] Specifically, this utility model is: a suspended hopper for a threshing machine, comprising a feed hopper, a hanging plate, and a vertical plate;

[0008] The feeding hopper has a feed inlet and a discharge outlet; the hanging plate is set on the upper edge of the discharge outlet, and the vertical plate is set on the upper edge of the feed inlet of the thresher. The feeding hopper is suspended on the vertical plate by the hanging plate, and the hanging plate and the vertical plate are locked by locking parts to realize the hanging of the feeding hopper, and the discharge outlet and the feed inlet are aligned.

[0009] Specifically, the hanging plate is L-shaped and is located at the top of the discharge port, and the hanging plate and the discharge port form a downward-opening hanging groove; the feed hopper is suspended on the vertical plate through the hanging groove.

[0010] The upright plate and the hanging plate have first bolt holes that mate with each other;

[0011] It also includes a first connecting bolt, which horizontally passes through the first bolt hole of the hanging plate and the upright plate, and is then locked by the first nut to achieve the locking and fixing of the hanging plate and the upright plate.

[0012] Specifically, the hanging plate includes a horizontal plate and a vertical plate. The horizontal plate is disposed on the upper edge of the discharge port, and the vertical plate is disposed below the horizontal plate and is fixedly connected to the horizontal plate.

[0013] Specifically, the width of the discharge port is greater than the width of the feeding port; both sides of the feeding port are provided with open plates, one side of which extends away from the thresher and towards the center line of the feeding port; both sides of the discharge port are provided with closing plates, one side of which extends away from the feed hopper and converges towards the center line of the discharge port, and the open plates and closing plates are in close contact with each other when the feed hopper is suspended on the upright plate.

[0014] In particular, the open plate and the closed plate also have mutually mating second bolt holes;

[0015] It also includes a second connecting bolt, which passes through the open plate and the closed plate and is then locked by a second nut to fix the open plate and the closed plate together.

[0016] Furthermore, a guide plate is provided at the lower edge of the discharge port, which extends into the feeding port when the feeding hopper is suspended on the vertical plate.

[0017] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0018] This invention suspends the hopper at the discharge port of the feed hopper and a vertical plate at the feeding port of the top cover. The original installation process, which required one person to lift the feed hopper and adjust its position to align the discharge port with the feeding port, while another person secured the hanging plate to the vertical plate, is now simplified. One person lifts and hangs the feed hopper, then adjusts its position to align the discharge port with the feeding port, and finally secures the hanging plate to the vertical plate. This avoids continuous lifting, reducing the difficulty of installing the feed hopper and the number of personnel required. Furthermore, suspending the feed hopper at the feeding port of the top cover allows for easy adjustment of its position to ensure alignment between the discharge port and the feeding port, preventing installers from holding the feed hopper for extended periods and effectively reducing the labor intensity of the feed hopper installation process.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model, so as to provide a better understanding of the concept of the present utility model, the technical problem solved, the technical features constituting the technical solution and the technical effects brought about.

[0026] For ease of representation, Figure 1 , Figure 2 and Figure 3 The threshing chamber below has been omitted;

[0027] like Figure 1 , Figure 2 and Figure 3 As shown, a suspended hopper for a threshing machine includes a feed hopper 2, a hanging plate 206, and a vertical plate 101;

[0028] The feeding hopper 2 has a feed inlet 201 and a discharge outlet 202; the hanging plate 206 is set on the upper edge of the discharge outlet 202, and the upright plate 101 is set on the upper edge of the feeding inlet 104 of the thresher. The feeding hopper 2 is suspended on the upright plate 101 by the hanging plate 206, and the hanging plate 206 and the upright plate 101 are locked by locking parts to realize the hanging of the feeding hopper 2, and the discharge outlet 202 is aligned with the feeding inlet 104.

[0029] The principle of this utility model is as follows:

[0030] By setting a hanging plate 206 on the upper edge of the discharge port 202 of the feed hopper 2 and a vertical plate 101 on the upper edge of the feeding port 104 of the upper cover 1, the feed hopper 2 can be directly suspended on the vertical plate 101 by the hanging plate 206. By pushing the feed hopper 2 to move along the length of the vertical plate 101, the position of the feed hopper 2 on the vertical plate 101 is adjusted so that the discharge port 202 of the feed hopper 2 is aligned with the feeding port 104 of the upper cover 1. This achieves the purpose of feeding crops into the feed port 201 of the feed hopper 2, and then feeding the crops into the thresher after passing through the discharge port 202 of the feed hopper 2 and the feeding port 104 of the upper cover 1. During this process, suspending the feed hopper 2 on the vertical plate 101 can be done by only one person. After suspending the feed hopper 2 on the vertical plate 101, it can be released and the same operator can then perform the subsequent alignment and fixing process. This reduces the labor intensity of the feed hopper 2 installation process and the number of installation personnel required, thus simplifying the installation process of the feed hopper 2.

[0031] As a preferred embodiment, such as Figure 1 , Figure 2 and Figure 3 As shown, the hanging plate 206 is L-shaped and is set on the upper edge of the discharge port 202, and the hanging plate 206 and the discharge port 202 form a downward-opening hanging groove; the feed hopper 2 is suspended on the vertical plate 101 through the hanging groove.

[0032] The upright plate 101 and the hanging plate 206 have first bolt holes 102 that mate with each other;

[0033] The locking component includes a first connecting bolt and a first nut. The first connecting bolt passes horizontally through the first bolt hole 102 of the hanging plate 206 and the upright plate 101, and is then locked by the first nut to achieve the locking and fixing of the hanging plate 206 and the upright plate 101.

[0034] In this embodiment, when installing the feed hopper 2, the feed hopper 2 is first lifted manually, and the mounting slot of the feed hopper 2 is placed on the upright plate 101. The feed hopper 2 can then be released, and the upright plate 101 will hold the feed hopper 2 in place. Then, by pushing the feed hopper 2 along the traveling direction of the vertical plate 101, the horizontal position of the feed hopper 2 on the vertical plate 101 is adjusted so that the first bolt hole 102 on the vertical plate 101 is aligned with the first bolt hole 102 on the hanging plate 206. The first connecting bolt passes through the first bolt hole 102 on both the vertical plate 101 and the hanging plate 206, and is then locked with the first nut, thus completing the position fixing process of the feed hopper 2. This changes the original installation process of the feed hopper 2, which required at least two people—one to lift the feed hopper 2 and adjust its position to align the bolt holes, while another person installed the feed hopper 2—to a process where one person first lifts and attaches the feed hopper 2, then adjusts its position to align the first bolt hole 102, and finally installs the first connecting bolt. The entire process can be completed by only one person, without the need for continuous lifting, reducing the installation difficulty and personnel requirements of the feed hopper 2, and simplifying the operation of the thresher.

[0035] As a preferred embodiment, such as Figure 3 As shown, the hanging plate 206 includes a horizontal plate and a vertical plate. The horizontal plate is disposed on the upper edge of the discharge port 202, and the vertical plate is disposed below the horizontal plate and is fixedly connected to the horizontal plate.

[0036] In this embodiment, a specific hanging plate 206 structure is provided, which includes a horizontal plate and a vertical plate. The horizontal plate is fixedly connected to the upper edge of the discharge port 202 of the feed hopper 2. The fixing method can be bolt connection or welding, thus serving as the installation position of the vertical plate. The vertical plate is set below the horizontal plate by welding and fixedly connected to the horizontal plate, thus forming the L-shape. Thus, the horizontal plate, the vertical plate, and the discharge port 202 of the feed hopper 2 form the hanging groove for installing the feed hopper 2.

[0037] As a preferred embodiment, such as Figure 1 , Figure 2 and Figure 3 As shown, the width of the discharge port 202 is greater than the width of the feeding port 104; both sides of the feeding port 104 are provided with open plates 103, one side of the open plates 103 extends away from the thresher and towards the center line of the feeding port 104; both sides of the discharge port 202 are provided with closing plates 204, one side of the closing plates 204 extends away from the feed hopper 2 and converges towards the center line of the discharge port 202, and the open plates 103 and closing plates 204 are closely attached to each other when the feed hopper 2 is suspended on the upright plate 101.

[0038] In this embodiment, by setting an open plate 103 at the feeding port 104 of the upper cover 1 and a closing plate 204 at the discharge port 202 of the feeding hopper 2, it is ensured that when the feeding hopper 2 is suspended on the upright plate 101, the open plate 103 and the closing plate 204 are closely attached. The shape of the tightly attached open plate 103 and the closing plate 204 is used to guide the crops, so that when the crops are put into the feeding hopper 2 and enter the upper cover 1 from the feeding port 104, the crops on both sides move along the contour of the open plate 103 and the closing plate 204, thereby avoiding the situation where the crops are stuck in the connecting seam when they are put into the feeding hopper 2.

[0039] As a further embodiment, such as Figure 1 , Figure 2 and Figure 3 As shown, the open plate 103 and the closed plate 204 also have mutually cooperating second bolt holes 203;

[0040] It also includes a second connecting bolt, which passes through the open plate 103 and the closed plate 204 and is locked by a second nut to fix the open plate 103 and the closed plate 204.

[0041] In this embodiment, the open plate 103 and the closed plate 204 are connected by a second connecting bolt. Specifically, the second connecting bolt passes through the second bolt hole 203 on the open plate 103 and the closed plate 204, and is then locked by a second lock nut to fix the open plate 103 and the closed plate 204, thus playing a role in auxiliary positioning. Also, since the threshing machine involves vibration during operation, the first connecting bolt may loosen. The connection between the open plate 103 and the closed plate 204 by the second connecting bolt can help distribute the weight of the feed hopper 2 in the suspended state in this case, making the feed hopper 2 more stable and preventing the feed hopper 2 from falling off when the first connecting bolt loosens.

[0042] As a preferred embodiment, a guide plate 205 is also provided on the lower edge of the discharge port 202 of the feed hopper 2. The guide plate 205 extends into the feeding port 104 when the feed hopper 2 is suspended on the vertical plate 101.

[0043] In this embodiment, as Figure 3As shown, by setting a guide plate 205 at the lower edge of the discharge port 202 of the feed hopper 2, after the crops are fed in, they fall into the middle of the threshing chamber below at the end of the guide plate 205, thus avoiding the problem of crops falling to the edge of the threshing chamber and causing poor threshing effect. It should be noted that by adjusting the length of the guide plate 205, the crops can fall directly onto the central axis when they fall into the threshing assembly below, which can effectively adjust the distribution of crops inside the threshing chamber and optimize the impact effect of the threshing structure inside the threshing chamber.

[0044] The terms "connection" and "fixing" appearing in this utility model description can refer to fixed connection, processing and forming, welding, or mechanical connection.
