Description

Technical Field

[0001] The utility model relates to the technical field of transportation equipment, and particularly relates to a bale conveyor. Background Art

[0002] A bale is a tightly bundled bunch of hay, straw, or other plant materials, used for livestock feed, storage, transportation, etc. In the prior art, a bale baler is usually used to compress hay into a tight bale, and a binding system is used for binding to finally form a cylindrical or square bale. The bales output by the bale baler can be transported by a conveyor belt for loading or stored in a warehouse at a high place.

[0003] At present, most of the existing conveyor belts are supported by brackets installed at the bottom, which limits the slope of the conveyor belt. Moreover, the length of the conveyor belt is fixed after being processed into a product. Therefore, when bales need to be transported to warehouses at different heights, there are certain limitations when using the existing conveyor belts. In addition, the existing conveyor belts mainly use rubber tracks or plate chains as conveying tools, which are relatively heavy and inconvenient to move. Moreover, since the conveying is carried out by using static friction, the bales are prone to roll when the slope of the conveyor belt is large. The above two points exacerbate the limitations of the existing conveyor belts. Summary of the Utility Model

[0004] In view of this, the purpose of the utility model is to provide a bale conveyor, which can transport bales to different heights, is convenient for transportation, and the bales are not easy to roll when being transported, so that it can be used under different working conditions.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] The bale conveyor includes a conveying frame, a motor, a first sprocket, a first chain, and a second sprocket; the conveying frame includes a plurality of bracket bodies detachably connected end to end; the motor is installed on one side of the conveying frame; the first sprocket, the first chain, and the second sprocket are all arranged inside the conveying frame; the first sprocket and the second sprocket are rotatably connected to both ends of the conveying frame, and the first sprocket is connected to the motor; the first chain extends along the length direction of the conveying frame, and a plurality of limiting members for hooking bales are arranged at intervals along the length direction on the first chain; the first sprocket is connected to the second sprocket through the first chain for transmission;

[0007] The motor can drive the first sprocket to rotate, and the rotation of the first sprocket drives the second sprocket to rotate through the first chain, so that the limiting members drive the bales to move along the conveying frame.

[0008] As an optional scheme, a speed reduction device is connected to the main shaft of the motor, and the motor is connected to the first sprocket through the speed reduction device.

[0009] As an alternative solution, the speed reduction device includes a driving wheel, a belt, a driven wheel, a sprocket shaft, a second chain and a third sprocket; the main shaft of the motor is coaxially connected to the driving wheel, and the driving wheel is connected to the driven wheel through belt transmission; the sprocket shaft is coaxially connected to the driven wheel and is connected to the third sprocket through the second chain, and the third sprocket is coaxially connected to the first sprocket; the diameter of the driving wheel is smaller than that of the driven wheel; the diameter of the sprocket shaft is smaller than that of the third sprocket.

[0010] As an alternative solution, it further includes a protective groove, which is arranged at the inner top of the conveying frame and extends along the length direction of the conveying frame. The upper side of the first chain is located in the protective groove, and the limiting member can slide along the protective groove.

[0011] As an alternative solution, the limiting member includes two blades respectively arranged at corresponding positions on both sides of the first chain. The blade consists of a tool tip located in the protective groove and a tool body located outside the protective groove. Both the tool tip and the tool body are in an "L" shape and face in opposite directions. The vertical side of the tool body is fixedly connected to the side of the first chain, the end of the horizontal side of the tool tip is connected to the end of the vertical side of the tool body, and the bottom surface of the horizontal side of the tool body is close to the inner bottom wall of the protective groove.

[0012] As an alternative solution, the end face of the horizontal side of the tool body is close to the inner side wall of the protective groove; both sides of the notch of the protective groove extend outward to form a supporting part, and the bottom surface of the horizontal side of the tool tip is close to the upper surface of the supporting part.

[0013] As an alternative solution, two adjacent bracket bodies are detachably connected by bolts.

[0014] As an alternative solution, a plurality of fourth sprockets are arranged at intervals along the length direction at the inner bottom of the conveying frame, and the fourth sprockets are in transmission connection with the lower side of the first chain.

[0015] Due to the adoption of the above technical solutions, the present utility model will have the following beneficial effects:

[0016] A bale conveyor provided by the present utility model adopts a plurality of support bodies that are detachably connected end to end. Different numbers of support bodies can be selected to build a conveying frame to convey bales according to the distance between the bale loading position and the unloading position. Compared with the existing conveyor belts, it can convey bales to different heights. Secondly, the motor drives the first sprocket to rotate, and the rotation of the first sprocket drives the second sprocket to rotate through the first chain. During the process of the first chain transmitting power, the limiting member that hooks the bale drives the bale to move along the conveying frame from the loading position to the unloading position. Since the bale is conveyed by means of chain drive throughout the process, compared with some existing conveyor belts, the overall weight is relatively light. Coupled with the detachable support body, the transportation is relatively convenient. In addition, since the bale is driven to move by the limiting member that hooks the bale, compared with the existing conveyor belts, the bale is not likely to roll down even when the conveying slope is relatively large.

[0017] Therefore, compared with the existing conveying frames that have certain limitations in use, the present utility model is not affected by the conveying height, slope and portability, and can be used under different working conditions, such as gardens, grasslands, workshops, etc. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] In the description of the present invention, it should be noted that unless otherwise clearly defined and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0029] Please refer to Figure 1-6 , in an embodiment of a bale conveyor of the present invention, the bale conveyor includes a conveying rack 1, a motor 2, a first sprocket 31, a first chain 32, and a second sprocket 33. Among them, the conveying rack 1 includes a plurality of rack bodies 11 detachably connected end to end. The rack body 11 is a box structure and is welded by steel materials such as vertical square pipes 111, horizontal square pipes 112, round pipes, and angle steels. The two sides of the end faces of two adjacent rack bodies 11 are detachably connected by bolts respectively.

[0030] On one side of the conveying frame 1, there is an installation frame 21. On one side surface of the installation frame 21, a motor 2 is installed by bolts. On the other side surface of the installation frame 21, two horizontally arranged and juxtaposed rings 22 are welded. A fixing pipe 23 is inserted into the two rings 22. A screw that can be threadedly connected to the fixing pipe 23 is provided through the side wall of the ring 22. Tightening this screw can fix the fixing pipe 23. On one side of the fixing pipe 23, two fixing pieces 24 that can be sleeved on the transverse square pipe 112 are arranged at intervals. At the bottom of the fixing piece 24, two bolts that penetrate the fixing piece 24 and the fixing pipe 23 are horizontally arranged. The above two bolts are respectively close to both sides of the vertical square pipe 111 and near the bottom of the transverse square pipe 112, so as to be able to limit the displacement of the fixing piece 24. Tightening the above two bolts fixes the fixing pipe 23, and thus the motor 2 is fixed.

[0031] The first sprocket 31, the first chain 32, and the second sprocket 33 are all arranged inside the conveying frame 1; the first sprocket 31 and the second sprocket 33 are respectively rotatably connected to both ends of the conveying frame 1, and the first sprocket 31 is connected to the motor 2 and driven to rotate by the motor 2. The first chain 32 extends along the length direction of the conveying frame 1, and a plurality of limiting members 4 for hooking the bales are arranged at intervals along the length direction on the first chain 32; the first sprocket 31 is drivingly connected to the second sprocket 33 through the first chain 32. In this embodiment, the way that the first sprocket 31 and the second sprocket 33 are rotatably connected inside the conveying frame 1 is not the main body of protection and will not be described in detail here. It can be the conventional installation method of sprockets in this industry.

[0032] When this embodiment is in use, turning on the motor 2 can drive the first sprocket 31 to rotate. The rotation of the first sprocket 31 drives the second sprocket 33 to rotate through the first chain 32. During the process of the first chain 32 transmitting power, the limiting member 4 drives the bale to move along the conveying frame 1.

[0033] Specifically, a reduction device can be connected to the main shaft of the motor 2. The outer side wall of the conveying frame 1 is installed with a transmission box 5 by bolts. The reduction device is installed inside the transmission box 5. The motor 2 is connected to the first sprocket 31 through this reduction device. The function of the reduction device is to reduce the rotation speed and increase the output torque at the same time, that is, to convert the high-speed and low-torque input of the motor 2 into the low-speed and high-torque output of the first sprocket 31, so as to more easily overcome the resistance.

[0034] More specifically, the above deceleration device can be set to include a driving wheel 61, a belt 62, a driven wheel 63, a sprocket shaft 64, a second chain 65, and a third sprocket 66; the main shaft of the motor 2 is coaxially connected to the driving wheel 61, the driving wheel 61 is drivingly connected to the driven wheel 63 through the belt 62, and the diameter of the driving wheel 61 is smaller than that of the driven wheel 63, thereby forming the first deceleration, reducing the input power speed and increasing the torque; the sprocket shaft 64 is coaxially connected to the driven wheel 63 and is drivingly connected to the third sprocket 66 through the second chain 65, and the diameter of the sprocket shaft 64 is smaller than that of the third sprocket 66, thereby forming the second deceleration, further reducing the speed and further increasing the torque. The third sprocket 66 is coaxially connected to the first sprocket 31, and the high-speed and low-torque input of the motor 2 is achieved with a larger reduction ratio through a series of two-stage decelerations, obtaining a higher torque output and a more stable transmission.

[0035] Furthermore, a protective groove 12 can be provided. The protective groove 12 is fixedly connected to the inner top of the conveying frame 1 and extends along the length direction of the conveying frame 1. The upper side of the first chain 32 is located within the protective groove 12 to prevent external factors from affecting the transmission of the first chain 32. The limiting member 4 can slide along the protective groove 12, and the protective groove 12 plays a role in supporting and guiding the limiting member 4 to prevent the limiting member 4 from running off track.

[0036] Specifically, the limiting member 4 can be set to include two blades respectively fixedly arranged at corresponding positions on both sides of the first chain 32, and the two blades can be fixedly connected by bolts passing through the first chain 32. The blade consists of a blade tip 41 located within the protective groove 12 and a blade body 42 located outside the protective groove 12. Both the blade tip 41 and the blade body 42 are in an "L" shape and face opposite directions. The vertical side of the blade body 42 is fixedly connected to the side of the first chain 32, the end of the horizontal side of the blade tip 41 is connected to the end of the vertical side of the blade body 42, and the bottom surface of the horizontal side of the blade body 42 is slidably connected to the inner bottom wall of the protective groove 12, enabling the limiting member 4 to slide along the protective groove 12.

[0037] More specifically, the end face of the horizontal side of the blade body 42 can be close to the inner side wall of the protective groove 12; both sides of the notch of the protective groove 12 extend outward to form a support portion, and the bottom surface of the horizontal side of the blade tip 41 is close to the upper surface of the support portion, so that the limiting member 4 can be better supported and guided without affecting the sliding of the limiting member 4.

[0038] On this basis, a plurality of fourth sprockets 34 are rotatably connected at intervals along the length direction of the inner bottom of the conveying frame 1, and the top of the fourth sprockets 34 is drivingly connected to the lower side of the first chain 32, making the transmission more stable.

[0039] The usage method or working principle of the present utility model is as follows:

[0040] First, select an appropriate number of support bodies 11 according to the distance between the loading position and the unloading position for transporting bales. Then, connect these support bodies 11 end to end with bolts to form a conveying rack 1, so that both ends of the conveying rack 1 correspond to the loading position and the unloading position respectively. Finally, turn on the motor 2 to drive the first sprocket 31 to rotate. The rotation of the first sprocket 31 drives the second sprocket 33 to rotate through the first chain 32. During the process of the first chain 32 transmitting power, the limiting member 4 that hooks the bale drives the bale to move along the conveying rack 1 from the loading position to the unloading position.

[0041] The above-described embodiments merely represent several implementation manners of the present utility model. The description is relatively specific and detailed, but it should not be construed as a limitation to the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model.
