Description

Technical Field

[0001] The utility model relates to the technical field of a whole-plant coix seed harvester, in particular to a compression device of a whole-plant coix seed harvester. Background Art

[0002] Job's tears, scientifically known as Coix lachryma-jobi, is a common grain widely used in food and medicine. In the field of food, Job's tears can be used to cook porridge, make cakes, etc. In recent years, with the advancement of agricultural modernization, the mechanized harvesting technology of Job's tears has also been developed and applied. Job's tears harvesters will produce straw and Job's tears during the harvesting process. Because the straw cannot be stored in large quantities in small harvesters, the straw must be discharged. Therefore, a compression device needs to be set in the straw container. The compression device is set to compress the straw into blocks, which are then easily discharged from the machine body.

[0003] In the entire system of the Job's tears harvester, the straw will first be separated from the Job's tears before compression. The commonly used separation method at present is to use the difference in mass between the Job's tears and the shell, and then use wind blowing to separate the two. At present, most of the compression devices inside the Job's tears harvester are sealed cylinder structures, powered by hydraulic cylinders, and use pressure plates to press the straw into blocks and then discharge them out of the machine body.

[0004] In the above process, when the straw is compressed by using a closed cylinder structure, the wind blown out from the separation mechanism is likely to generate backflow in the sealed cylinder, which will affect the straw briquetting efficiency to a certain extent. In order to improve the efficiency of the entire straw briquetting process, the utility model provides a compression device for a whole-plant coix harvester to meet the needs. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a compression device of a whole-plant Job's tears harvester by setting a driving component. The compression chamber formed by the lifting door, upper pressure plate, bottom plate and side push plate in the driving component is not sealed. Such a setting has two advantages. First, because the air exhausted in the separation device needs to be exhausted, the non-sealed cavity setting will not allow air to flow back, thereby improving the straw briquetting efficiency; second, because the lifting door is very heavy, if the lifting door is completely closed, it will affect the balance. If the lifting door is unstable in operation, it may even damage the spiral device. When compressing the straw, the height of the lifting door can be appropriately adjusted. This can not only reduce the economy, but also improve stability. The above setting can solve the problem of low efficiency of straw briquetting by existing compression devices.

[0006] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0007] A compression device for a whole-plant Job's tears harvester comprises a harvester body, a bottom plate fixedly connected inside the harvester body, a top plate fixedly connected to the top of the bottom plate, a lifting door installed on the top of the bottom plate; a drive assembly, the drive assembly is used to briquette the straw on the bottom plate, and the drive assembly is respectively connected to the bottom plate, the top plate and the lifting door.

[0008] Optionally, the driving assembly includes a first air pump mechanism fixedly connected to one side of the top plate, the output end of the first air pump mechanism is fixedly connected to an upper pressure plate, one side of the bottom plate is fixedly connected to a second air pump mechanism, the output end of the second air pump mechanism is fixedly connected to a side push plate, and a motor is fixedly connected to the outer wall of the top plate.

[0009] Optionally, the output end of the motor is fixedly connected to a gear set, and a screw is installed on the gear set.

[0010] Optionally, a guide rod is fixedly connected between the bottom plate and the top plate, and the guide rod is inserted on one side of the lifting door.

[0011] Optionally, a circular pressing plate is fixedly connected to the bottom of the upper pressing plate, and a limiting plate is fixedly connected to the bottom of the upper pressing plate.

[0012] Optionally, the limiting plate is located on the outer side of the circular pressure plate.

[0013] Optionally, the bottom of the upper pressing plate and the top of the circular pressing plate are both fixedly connected with the same elastic sheet, and the upper pressing plate and the circular pressing plate are fixedly connected via the elastic sheet.

[0014] Optionally, a gradual-change block is fixedly connected to the outer side wall of the upper pressing plate, and a gradual-change slot matching the shape of the gradual-change block is formed on the inner side wall of the limiting plate.

[0015] Compared with the prior art, the utility model has at least the following beneficial effects:

[0016] In the above scheme, by setting up a driving assembly, the compression chamber formed by the lifting door, upper pressure plate, bottom plate and side push plate in the driving assembly is not sealed. Such a setting has two advantages. First, because the air exhausted in the separation device needs to be discharged, the non-sealed cavity setting will not allow air to flow back, thereby improving the straw block efficiency; second, because the lifting door is very heavy, if the lifting door is completely closed, it will affect the balance. If the lifting door is unstable in operation, it may even damage the spiral device. When compressing the straw, the height of the lifting door can be appropriately adjusted, which can not only reduce the economy but also improve stability.

[0017] By setting a circular pressure plate, the circular pressure plate will shake at the moment of pressing the straw, so that the straw can be separated from the circular pressure plate with the help of the force during the shaking process, thereby preventing a large amount of straw from sticking to the surface of the circular pressure plate, affecting the squeezing effect of the circular pressure plate on the straw, and increasing the energy consumption of the first air pump mechanism. Furthermore, the gradient block on the side of the circular pressure plate is a gradient structure setting, and the size of the gradient block is larger as it is farther away from the upper pressure plate. This setting is to allow the circular pressure plate to shake with different intensities during the resetting process, thereby improving the shaking-off effect of the straw.

[0018] To sum up, under the combined action of the lifting door and the circular pressure plate, the system improves the entire process of straw compression. While improving the compression efficiency, it also takes into account the impact of the straw structure itself on compression. In addition, the compression device provided in this application also takes into account the structural strength and cost, thereby increasing the practicality of the compression device.

The device may be oriented in other ways, and the spatially relative descriptors used herein may be similarly interpreted accordingly.

[0034] like Figures 1 to 6 As shown, an embodiment of the utility model provides a compression device for a whole-plant Job's tears harvester, including a harvester body 1, a bottom plate 2 is fixedly connected to the inside of the harvester body 1, a top plate 3 is fixedly connected to the top of the bottom plate 2, and a lifting door 7 is installed on the top of the bottom plate 2; a drive assembly, the drive assembly is used to briquette the straw on the bottom plate 2, and the drive assembly is respectively connected to the bottom plate 2, the top plate 3 and the lifting door 7.

[0035] As an implementation method in this embodiment, Figures 2 to 4 As shown, the driving assembly includes a first air pump mechanism 4 fixedly connected to one side of the top plate 3, the output end of the first air pump mechanism 4 is fixedly connected to the upper pressure plate 401, and one side of the bottom plate 2 is fixedly connected to the second air pump mechanism 5, and the output end of the second air pump mechanism 5 is fixedly connected to the side push plate 501. The compression device provided in the present application is not a sealed cavity structure, and the driving assembly is used to adjust the movement of the lifting door 7, the upper pressure plate 401 and the side push plate 501 respectively, wherein the first air pump mechanism 4 and the second air pump mechanism 5 are both provided with compression power by air pumps, and are connected to the air valve through pipelines, and external work is achieved by controlling the power on and off of the air valve. Hydraulic control is not used because of the fear that hydraulic oil will drip into the straw and pollute the straw, so as to prevent the straw from being used for livestock agriculture.

[0036] In this embodiment, if Figures 2 to 4As shown, a motor 8 is fixedly connected to the outer wall of the top plate 3, a gear set 9 is fixedly connected to the output end of the motor 8, a screw 10 is installed on the gear set 9, a guide rod 6 is fixedly connected between the bottom plate 2 and the top plate 3, the guide rod 6 is inserted on one side of the lifting door 7, and on the bottom plate 2, a second air pump mechanism 5 and a side push plate 501 are installed on one side, and the lifting door 7 is installed on the other side, one side of the lifting door 7 is screwed with a screw 10, and the other side is inserted with the guide rod 6. When the motor 8 is started, the motor 8 first drives the gear set 9 to rotate, and then the gear set 9 drives the screw 10 to rotate. During the rotation of the screw 10, the lifting door 7 can be driven to rise and fall. During the lifting and falling process of the lifting door 7, the guide rod 6 plays a role in the lifting door 7. The guiding and limiting functions are as follows: when squeezing the straw, the lifting door 7 needs to be lowered by one end to be located on the upper surface of the bottom plate 2. At this time, the lifting door 7 serves as an extrusion surface for compressing the straw, and combined with the extrusion effect of the upper bottom plate 2, the upper pressure plate 401 and the side push plate 501, the compression of the straw can be achieved. In order to improve the extrusion effect on the straw, the lifting door 7 must have a certain weight, and the inner wall of the lifting door 7 is smooth. Because the lifting door 7 is relatively heavy, the structure for driving the lifting door 7 to rise and fall is driven by the screw 10. This driving method has strong stability and is not easy to deform. Combined with the guiding and limiting functions of the upper guide rod 6, the lifting door 7 has a higher balance and increased durability.

[0037] Furthermore, the lifting door 7 and the bottom plate 2 are not sealed structures. There are two considerations for this arrangement. First, because the air exhausted in the separation device needs to be exhausted, there must be an air outlet, so the lifting door 7 cannot be closed; second, because the lifting door 7 is very heavy, if the lifting door 7 is completely closed, it will affect the balance. If the lifting door 7 is unstable in operation, it may even damage the spiral device. When compressing the straw, the height of the lifting door 7 can be appropriately adjusted, which can not only reduce the economy but also improve stability.

[0038] In this embodiment, if Figures 2 to 6As shown, the bottom of the upper pressing plate 401 is fixedly connected to a circular pressing plate 402, and the bottom of the upper pressing plate 401 is fixedly connected to a limiting plate 403, and the limiting plate 403 is located on the outside of the circular pressing plate 402. The bottom of the upper pressing plate 401 and the top of the circular pressing plate 402 are fixedly connected to the same spring piece 404, and the upper pressing plate 401 and the circular pressing plate 402 are fixedly connected by the spring piece 404. The outer wall of the upper pressing plate 401 is fixedly connected to a gradual card block 405, and the inner wall of the limiting plate 403 is provided with a gradual card groove 406 that is compatible with the shape of the gradual card block 405. In addition to considering the sealing performance of the extrusion chamber, the present application also considers the material of the straw. After the straw is harvested from the field, there will be a part of plant liquid inside the straw. The liquid will be squeezed out of the straw during the extrusion process, thereby increasing the adhesion of the straw, which leads to When the upper pressing plate 401 is in the process of squeezing the straw, the straw will adhere to the surface of the upper pressing plate 401, thereby affecting the flatness of the upper pressing plate 401. In the process of continuously compressing the straw, the effect of straw compression will be affected. In order to solve the above problem, a circular pressing plate 402 is set at the bottom of the upper pressing plate 401, and the circular pressing plate 402 and the upper pressing plate 401 are connected by a spring plate 404. The spring plate 404 itself has a certain elasticity. Under the action of elasticity, after the circular pressing plate 402 squeezes the straw, it will squeeze the spring plate 404. When the upper pressing plate 401 moves up, the circular pressing plate 402 will return to its original position under the action of elasticity. The reason for choosing the spring plate 404 is that the overall structure of the spring plate 404 is circular. Such a structural setting makes the structural contour of the spring plate 404 consistent with that of the circular pressing plate 402, so that the elastic force exerted on the circular pressing plate 402 when squeezing the straw is more uniform.

[0039] Furthermore, the limit plate 403 is arranged on the outer side of the circular pressure plate 402. When the circular pressure plate 402 squeezes the spring piece 404, it moves toward the upper pressure plate 401. At this time, the gradual block 405 on the outer wall of the circular pressure plate 402 is snapped into the gradual slot 406 on the inner wall of the limit plate 403. The shape of the gradual block 405 is consistent with the shape of the gradual slot 406. Therefore, the two are snapped together to produce a certain clamping force. Under the action of this force, the gradual block 405 will exert a pulling force on the circular pressure plate 402 to move. When the upper pressure plate 401 moves upward, the circular pressure plate 402 will not reset immediately under the clamping action of the gradual block 405, but will stay for a short time and then reset. This arrangement causes the circular pressure plate 402 to shake under the action of the spring piece 404. The effect of the shaking is that the straw adhered to the bottom of the circular pressure plate 402 will fall off along with its shaking.

[0040] Furthermore, the gradual change block 405 is a gradual change structure, and the size of the gradual change block 405 is larger as it is farther away from the upper pressure plate 401. This setting is to allow the circular pressure plate 402 to vibrate with different intensities during the resetting process, thereby improving the shaking effect on the straw.

[0041] In summary, under the combined action of the lifting door 7 and the circular pressure plate 402, the entire process of straw compression is systematically improved. While improving the compression efficiency, the influence of the straw structure on the compression is also considered.

[0042] The working principle provided by the utility model is that when in use, the motor 8 is started first. When the motor 8 is started, the motor 8 first drives the gear set 9 to rotate, and then the gear set 9 drives the screw 10 to rotate. During the rotation of the screw 10, the lifting door 7 can be driven to rise and fall, so that the lifting door 7 is lowered to the upper surface of the bottom plate 2, and then the first air pump mechanism 4 is started to make the upper pressure plate 401 press downward. After repeated downward pressure, the straw on the surface of the bottom plate 2 will be squeezed into blocks. Finally, the height of the lifting door 7 is readjusted to move it away from the bottom plate 2 to provide avoidance space for the block-shaped straw, and the second air pump mechanism 5 is started to make the side push plate 501 push the block-shaped straw out from the bottom of the lifting door 7.

[0043] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the following preferred embodiments of the present invention, and those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0044] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
