Description

Technical Field

[0001] This utility model relates to the field of threshing technology, and in particular to a threshing machine. Background Technology

[0002] A threshing machine is a harvesting machine that separates the grains from the stalks of crops, primarily grain crops. Different types of threshing machines exist depending on the crop; for example, a "rice threshing machine" is suitable for rice, and a "corn threshing machine" is suitable for corn, etc. The advent of threshing machines has greatly reduced the labor intensity of harvesting and improved agricultural productivity.

[0003] Existing threshers come in various forms. For example, utility model patent CN222328479U discloses a thresher, and CN222603109U discloses a thresher for lentil combine harvesting. Research has found that existing threshers have complex structures, are heavy, and expensive. In remote areas with poor road conditions, it is difficult to transport the thresher directly to the work location, which is time-consuming and labor-intensive. Furthermore, subsequent maintenance is inconvenient, and they cannot meet actual threshing needs. Utility Model Content

[0032] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0033] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0034] This utility model provides a threshing machine, such as Figure 1-7 As shown, it includes rack 1, wherein:

[0035] The upper part of the frame 1 is provided with a threshing chamber 11, and the lower part of the frame 1 is a hollow structure. The threshing drum 2 is rotatably assembled inside the threshing chamber 11. The frame 1 is provided with a drive device (not shown) that drives and connects to the threshing drum 2.

[0036] A protective cover 3 is provided on the frame 1 above the threshing chamber 11. The protective cover 3 has a feed inlet 12 connected to the threshing chamber 11 on one side along the width direction of the frame 1, and a discharge outlet 13 connected to the threshing chamber 11 on the other side along the width direction of the frame 1 below. A pair of lifting rod insertion holes 32 are provided on both sides of the protective cover 3 along the length direction of the frame 1.

[0037] During transportation, if the road is blocked in remote areas, the thresher can be easily lifted by inserting a lifting rod (not shown) into the lifting rod insertion hole 32 and transported to the working position. During operation, the crop to be threshed is held in hand and placed in the feed inlet 12 of the thresher. The drive device drives the threshing drum 2 to rotate, threshing the crop and discharging it from the discharge outlet 13.

[0038] This utility model of a threshing machine uses only a frame, threshing chamber, threshing drum, and drive device connected together. Compared with the prior art, it has a simple structure, light weight, low price, and is convenient for later maintenance. The protective cover has a pair of lifting rod insertion holes on both sides along the length of the frame. In remote areas with poor road conditions, the lifting rod can be inserted into the lifting rod insertion holes to easily lift the threshing machine, making it convenient to transport the threshing machine to the working position, saving time and effort, and meeting actual threshing needs.

[0039] like Figure 4 As shown, the hollow structure is preferably a frame-type hollow structure. The frame-type hollow structure reduces the weight of the thresher to the greatest extent while ensuring the overall frame’s sturdiness and stability, making it more convenient for transportation.

[0040] like Figure 5 As shown, the threshing drum 2 may include a drum body 21 and threshing brushes 22 located on the drum body 21. The number of threshing brushes 22 can be 4-6 sets, evenly arranged along the circumference of the drum body 21 to facilitate threshing operations. In the embodiment shown in the figure, the number of threshing brushes 22 is 5 sets. The brush teeth of adjacent sets of threshing brushes 22 can be staggered. This staggered distribution can improve the threshing operation, increase threshing efficiency, and achieve good threshing results. Each brush tooth of the threshing brush 22 can be triangular.

[0041] like Figure 2 As shown, a pulley 4 for connecting the shaft 23 of the threshing drum 2 can be provided on the outer side of the threshing chamber 11. The drive device drives the pulley 4 to facilitate the threshing drum 2 to perform the threshing operation. A pulley cover 41 can be provided on the frame 1 at the pulley 4 to protect the pulley 4. The other side of the protective cover 3 along the width direction of the frame 1 can be a screen structure 31 to facilitate the dispersal of dust generated during threshing.

[0042] like Figure 1-3As shown, a horizontally arranged feed tray 5 is detachably connected (specifically, it can be detachably connected by bolts) at the feed inlet 12 on the frame 1. A reinforcing connecting plate 51 can be provided below the feed tray 5 to facilitate the support of the crops to be threshed. The setting of the reinforcing connecting plate 51 improves the firmness and stability of the feed tray 5.

[0043] Continue as Figure 1-3 As shown, the bottom surface of the threshing chamber 11 can be an inclined surface that gradually decreases towards the discharge port 13. The frame 1 has an inclined discharge tray 6 that is detachably connected (specifically, it can be detachably connected by bolts) at the discharge port 13. In this way, after the crop is threshed, it can be easily discharged from the discharge port 13 under the action of gravity.

[0044] like Figure 6 As shown, an end cap 33 can be provided at the lifting rod insertion hole 32. The edge of the end cap 33 is hinged to the protective cover 3 by a pin 34. In this way, when not in transport, the lifting rod insertion hole 32 can be hidden to prevent rainwater from entering, and at the same time, it makes the whole thing more aesthetically pleasing. When transport is required, the end cap 33 is rotated, and the end cap 33 rotates along the pin 34 to insert the lifting rod.

[0045] The drive device can adopt various structural forms readily conceived by those skilled in the art, such as a traditional foot-operated drive; however, to save manpower and facilitate implementation, the present invention preferably adopts the following structural form:

[0046] like Figure 7 As shown, the driving device can be a drive motor. The bottom of the frame 1 is provided with a pair of slide rails 14, and a power mounting seat 15 is slidably connected on the pair of slide rails 14. The drive motor is located on the power mounting seat 15. The bottom of the frame 1 is also provided with an adjustment locking member 16 that can be adjusted to lock the power mounting seat 15 on the pair of slide rails 14.

[0047] Furthermore, the adjusting locking element 16 can be an adjusting locking rod. One end of the adjusting locking rod is hinged to one of the two slide rails 14, and the middle of the adjusting locking rod is hinged to the power mounting base 15. The other slide rail of the pair of slide rails is provided with a locking groove 141 for accommodating the other end of the adjusting locking rod, which facilitates the adjustment and locking function. In use, the adjusting locking rod is held and pulled, causing the power mounting base 15 to slide on the pair of slide rails. After adjusting to the appropriate position, the end of the adjusting locking rod is placed into the corresponding locking groove 141 to lock the power mounting base 15.

[0048] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
