Description

Technical Field

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

[0002] A threshing machine is a harvesting machine that separates the grains of crops from their stalks. It primarily refers to harvesting machinery for grain crops. Depending on the grain crop, there are different types of threshing machines. For example, a "rice threshing machine" is suitable for rice threshing; one used for corn threshing is called a "corn threshing machine," and so on. The rice threshing machine, commonly known as a "rice threshing machine," is the most common rice threshing machine. It requires harvesting the rice first, and then uses this machine to separate the rice grains from the stalks. Rice threshing machines are divided into two categories: one is manually driven, called a "human-powered rice threshing machine," which is a semi-mechanized tool; the other is powered, called a "powered rice threshing machine." The advent of rice threshing machines has greatly reduced the labor intensity of rice harvesting and improved agricultural productivity.

[0003] Existing threshing machines are all powered by electricity. In some remote areas, such as terraced fields, transporting power would increase labor costs. Also, some customers grow very little and do not need power. Utility Model Content

[0004] The purpose of this utility model is to provide a threshing machine that addresses the problem that existing threshing machines are all powered by electricity. In some remote areas, such as terraced fields, transporting power would increase labor costs. Also, some customers grow very little and do not need power, so the threshing can be done manually, thus reducing operating costs.

[0005] This utility model is implemented as follows: a threshing machine, comprising:

[0006] A threshing machine frame, on which a protective cover assembly and a threshing assembly are installed for threshing grain crops;

[0007] The threshing assembly includes:

[0008] A threshing roller is rotatably mounted on the frame of the threshing machine, and a small gear is fixedly installed on the shaft end of the threshing roller;

[0009] A large gear is rotatably fitted onto the threshing machine frame, and the large gear meshes with a small gear.

[0010] The power linkage is movably mounted on the large gear.

[0011] The power frame is rotatably mounted on the threshing machine frame, and the power frame is also hinged to the power connecting rod;

[0012] The pedal is fixedly installed on the end face of the power frame and is used by the user to step on it to drive the large gear.

[0013] As a further embodiment of this utility model, a number of staggered threshing blocks are fixedly installed along the length of the threshing roller, and the ratio of the size of the small gear to the size of the large gear is between 1 and (3-4).

[0014] As a further embodiment of this invention, a synchronous pulley is also fixedly installed on the other end of the threshing roller.

[0015] As a further embodiment of this utility model, it also includes a mounting assembly, disposed on the threshing machine frame, for mounting the power motor, the mounting assembly comprising:

[0016] Mounting brackets, both of which are fixedly mounted on the threshing machine frame by bolts, and one of the two mounting brackets is provided with a mounting groove;

[0017] The mounting rod is rotatably fitted onto the other mounting bracket mentioned above;

[0018] The mounting base is slidably fitted on the two mounting brackets. The mounting base is also hinged to the mounting rod. The mounting base is used to support the power motor, which is connected to the synchronous pulley via a synchronous belt.

[0019] As a further embodiment of this utility model, the protective cover assembly includes:

[0020] The inner protective cover is bolted to the threshing machine frame. The inner protective cover is arc-shaped on the side away from the threshing machine frame, and holes are provided at both ends of the inner protective cover.

[0021] A dust exhaust protective cover is fitted onto the inner protective cover. The dust exhaust protective cover is bolted to the threshing machine frame.

[0024] As a further embodiment of this utility model, a gear protective cover is movably installed on one side of the threshing machine frame to protect the small gear and the large gear, and a fixed protective cover is movably installed on the other side of the threshing machine frame to protect the synchronous pulley.

[0025] This utility model provides a threshing machine that, through the setting of the threshing components, applies force to the pedal, and then ensures power supply to the threshing machine through the power transmission between the large and small gears. For threshing grain crops on terraced fields, there is no need to transport power to the threshing machine, avoiding damage to transport power sources (such as diesel engines, gasoline engines, etc.) and other hazards. For some small-scale growers, threshing can be done manually, reducing the cost of use. The setting of the protective cover components enables dust removal during grain threshing, and the multiple protective covers of different shapes provide better protection and use for the threshing machine.

[0033] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0034] It is understood that the terms “first” and “second” as used herein may be used to describe various elements, but unless otherwise stated, these elements are not limited by these terms. These terms are used only to distinguish one element from another.

[0035] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0036] like Figures 1 to 6 As shown, a threshing machine according to one embodiment of the present invention includes:

[0037] The threshing machine frame 1 is equipped with a protective cover assembly 2 and a threshing assembly 3 for threshing grain crops.

[0038] Threshing component 3 includes:

[0039] The threshing roller 31 is rotatably fitted on the threshing machine frame 1, and a small gear 32 is fixedly installed on the shaft end of the threshing roller 31.

[0040] The large gear 33 is rotatably fitted on the threshing machine frame 1, and the large gear 33 is meshed with the small gear 32.

[0041] The power linkage 34 is movably mounted on the large gear 33;

[0042] The power frame 35 is rotatably mounted on the threshing machine frame 1, and the power frame 35 is also hinged to the power connecting rod 34.

[0043] The pedal 36 is fixedly installed on the end face of the power frame 35 and is used by the user to step on it to drive the large gear 33.

[0044] Specifically, as a further embodiment of this utility model, a number of staggered threshing blocks are fixedly installed on the threshing roller 31 along its length, and the size ratio of the small gear 32 to the large gear 33 is between 1 and (3-4).

[0045] In this embodiment of the invention, in practical applications, when some remote areas, such as terraced fields or where farmers with limited planting areas need to thresh grain crops, the user applies pressure to the pedal 36. The pedal 36 drives the large gear 33 to rotate through the power frame 35 and the power connecting rod 34. Then, through the meshing force, the small gear 32 drives the threshing roller 31 to rotate, thus threshing the grain crops. Since the size of the large gear 33 is different from that of the small gear 32, one rotation of the large gear 33 will cause the small gear 32 to rotate several times, thereby achieving higher power output and transmission. This results in a faster rotation speed of the threshing roller 31, while also reducing the labor intensity of the user when stepping on the pedal 36 and saving physical strength.

[0046] By setting up the threshing assembly 3, a force is applied to the pedal 36, and then the power is transmitted between the large gear 33 and the small gear 32 to ensure that the threshing machine is powered. When threshing grain crops on terraced fields, there is no need to transport power to the threshing machine, avoiding damage to the transport power (such as diesel engines, gasoline engines, etc.) and other hazards. In addition, some small-scale growers can solve the threshing problem by manpower, reducing the cost of use.

[0047] like Figures 1 to 6 As shown, in a further embodiment of the present invention, a synchronous pulley 37 is also fixedly installed on the other shaft end of the threshing roller 31;

[0048] Specifically, as a further embodiment of this utility model, it also includes a mounting component 4, which is disposed on the threshing machine frame 1 and used to mount the power motor. The mounting component 4 includes:

[0049] Mounting bracket 41, both mounting brackets 41 are fixedly mounted on the threshing machine frame 1 by bolts, and one of the two mounting brackets 41 is provided with a mounting groove 43;

[0050] The mounting link 42 is rotatably fitted onto another mounting bracket 41 of the two described;

[0051] Mounting base 44 is slidably fitted on two mounting brackets 41. Mounting base 44 is also hinged to mounting link 42. Mounting base 44 is used to support the power motor. The motor is connected to synchronous pulley 37 via synchronous belt.

[0052] In this embodiment of the utility model, in actual application, the power motor is fixed on the mounting base 44. The position of the motor can be adjusted by the cooperation of the mounting rod 42 and the mounting groove 43. Then, the motor is connected to the synchronous pulley 37 by the synchronous belt. The rotation of the threshing roller 31 can be driven by electricity to thresh the grain crops.

[0053] like Figures 1 to 6 As shown, in a further embodiment of this utility model, the protective cover assembly 2 includes:

[0054] The inner protective cover 21 is bolted to the threshing machine frame 1. The inner protective cover 21 is arc-shaped on the side away from the threshing machine frame 1, and holes are provided at both ends of the inner protective cover 21.

[0055] Dust exhaust cover 22 is fitted onto inner cover 21. Dust exhaust cover 22 is bolted to threshing machine frame 1. Dust exhaust hole is opened on one side of raw material threshing machine frame 1. Sealing cover 221 is movably installed at both ends of dust exhaust cover 22.

[0056] The outer protective cover 23 is fitted onto the dust discharge protective cover 22, and the outer protective cover 23 is installed on the threshing machine frame 1 by bolts;

[0057] In this embodiment of the present invention, during actual application, when threshing, the inner protective cover 21 and the outer protective cover 23 are disassembled so that the dust generated during threshing can be discharged through the dust discharge hole on the dust discharge protective cover 22. When the road is not convenient for transporting the thresher, the sealing cover 221 is removed so that the fixing rod passes through the holes on the dust discharge protective cover 22 and the inner protective cover 21, which makes it easier to lift and move the thresher and reduces the difficulty of transporting the thresher.

[0058] like Figures 1 to 6 As shown, in a further embodiment of the present invention, a feed plate 11 is movably installed on the end face of the threshing machine frame 1, and a discharge plate 12 is movably installed on the free end of the threshing machine frame 1, for feeding the grain crops and discharging the grain crops after threshing.

[0059] In this embodiment of the invention, in practical application, the feed plate 11 can support the grain crop during threshing, allowing it to enter the threshing machine frame 1 more easily, while the discharge plate 12 can support the threshed grain crop, facilitating the collection of the threshed grain crop.

[0060] like Figures 1 to 6 As shown, as a further embodiment of the present utility model, a gear protective cover 13 is movably installed on one side of the threshing machine frame 1 to protect the small gear 32 and the large gear 33, and a fixed protective cover 14 is movably installed on the other side of the threshing machine frame 1 to protect the synchronous pulley 37.

[0061] In this embodiment of the utility model, in practical application, the gear protective cover 13 and the fixed protective cover 14 respectively protect the small gear 32, the large gear 33 and the synchronous belt pulley 37, so as to prevent grain crops from falling and blocking the power transmission of the threshing machine during the threshing process.

[0062] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
