Description

Technical Field

[0001] This invention relates to the field of agricultural product conveying technology, specifically to a grain conveying device that is flexible and convenient for loading. Background Technology

[0002] After harvesting, grains typically need to be dried to reduce moisture content, prevent mold, and facilitate subsequent storage. Currently, in rural areas, grains are commonly spread out to dry in drying yards before being collected and bagged. However, the traditional collection process after drying still relies heavily on manual labor. Workers need to use sieves or shovels to scoop the grains spread on the ground into bags, while another person needs to hold the bags open to assist. This method is extremely inefficient, labor-intensive, and requires at least two people working together.

[0003] To address the inefficiency of manual grain harvesting and bagging, several existing technologies offer solutions. For example, a mobile grain conveyor system uses a conveyor belt support and a small diesel engine to drive rollers, lifting and transporting the grain via the conveyor belt, thus reducing the workload to some extent. Furthermore, a new type of drying yard grain harvester uses a grain collection device in conjunction with a conveyor belt to transport the dried grain to a receiving box, achieving mechanized grain harvesting operations.

[0004] However, the existing grain conveying devices mentioned above still have shortcomings in practical applications: their discharge end usually discharges directly into the receiving grain box or a fixed position. In cases where bagging is required, the grain flowing out of the discharge port still needs to be manually fed into the bag, and the bag opening and positioning still require manual assistance. This does not truly solve the problem of manual bag opening and inconvenient operation in the bagging process. Summary of the Invention

This ensures that the amount of grains in each filling bag remains the same during subsequent bagging via the filling module. This invention eliminates the need for secondary weighing of the grains using other weighing equipment, further improving grain filling efficiency. Attached Figure Description

[0020] The specific embodiments of the present invention will be described in detail below, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0021] Example 1 Existing grain conveying devices typically discharge directly into the receiving grain bin or a fixed location. In cases where bagging is required, manual labor is still needed to collect the grain flowing out of the discharge port into the bag, and the opening and positioning of the bag still require manual assistance.

[0022] like Figures 1 to 5 In this embodiment, a flexible and convenient grain conveying device includes a receiving module 1 for feeding grains on the ground. The receiving module 1 is connected to a transmission module 2, which is used to transport the grains fed by the receiving module 1. Specifically, when the grain conveying device of this embodiment is used, it is moved to the ground where the grains are piled up. The grains can first be fed through the receiving module 1, and the fed grains are lifted upwards along the transmission module 2 to facilitate subsequent bagging.

[0023] It also includes a discharge module 3 and a loading module 4. The discharge module 3 is connected to the transmission end of the transmission module 2 to output the grains conveyed by the transmission module 2 in equal quantities. The loading module 4 is used to load the grains discharged from the discharge module 3. The working principle of this embodiment is as follows: When conveying and loading grains piled on the ground, the conveying device is first moved to the ground where the grains are piled. The grains can be fed through the receiving module 1. After being fed, the grains are lifted upward along the conveying module 2. Under the action of gravity, the grains are discharged quantitatively through the discharging module 3. Finally, the grains discharged from each group are bagged through the loading module 4.

[0024] It should be emphasized that the core improvement of this embodiment is that: the receiving module 1 can automatically feed the grains piled on the ground, and after feeding is completed and transported by the transmission module 2, the grains can be quantitatively discharged by the discharge module 3 based on the capacity of the filling bag, so that when the filling module 4 is used for bagging, the amount of grains in each filling bag is kept the same. This embodiment does not require the use of other weighing equipment to weigh the grains a second time, which further improves the grain filling efficiency.

[0025] It should be noted that, such as Figures 1-4 The receiving module 1 of this embodiment includes a horizontally placed receiving cylinder 101. A receiving port is opened on the cylinder wall of the receiving cylinder 101. A auger conveyor rod 102 is rotatably arranged inside the receiving cylinder 101. The receiving cylinder 101 is fixed to one side of the base 103. A receiving motor 104 is fixedly arranged on the base 103. The drive end of the receiving motor 104 is connected to the auger conveyor rod 102 through a belt pulley structure. Specifically, in this embodiment, a movable wheel can be set at the bottom of the base 103 to facilitate the adjustment of the position of the conveying device. Correspondingly, when receiving materials, the receiving motor 104 is started to drive the auger conveyor rod 102 to rotate. During the rotation of the auger conveyor rod 102, the grain on the ground can be sucked into the receiving cylinder 101 through the receiving port.

[0026] It should be noted that the transmission module 2 in this embodiment includes a transmission cylinder 201 fixed on the receiving cylinder 101. The transmission cylinder 201 is inclined and has a discharge port 204 at its end. The transmission cylinder 201 is connected to the receiving cylinder 101. A conveyor belt 202 is provided inside the transmission cylinder 201. One end of the conveyor belt 202 is sleeved on the auger conveyor rod 102, and the other end is sleeved on the rotating roller. The rotating roller is rotated and arranged in the transmission cylinder 201. Several sets of baffles 203 are evenly fixed on the conveyor belt 202. Specifically, in this embodiment, the auger conveyor rod 102 can synchronously drive the transmission of the conveyor belt 202 during rotation. During the transmission of the conveyor belt 202, the grain collected in the receiving cylinder 101 is conveyed upward along the conveyor belt 202 and finally discharged through the discharge port 204. Accordingly, this embodiment does not need to set up other servo drive equipment to drive the transmission of the conveyor belt 202. With the rotation of the auger conveyor rod 102, the effect of synchronously and automatically driving the transmission of the conveyor belt 202 can be achieved.

[0027] like Figures 4 to 9 In this embodiment, the discharge module 3 includes a hopper 301 fixedly arranged below the discharge port 204. A discharge port 302 is provided at the bottom of the hopper 301. A discharge plate 501 is slidably arranged below the discharge port 302. The upper surface of the discharge plate 501 slidably fits against the discharge port 302. A first receiving interface 502 and a second receiving interface 503 are respectively provided on both sides of the discharge plate 501 for connecting to the discharge port 302. The first receiving interface 502 is connected to a first discharge box 402 below, and the second receiving interface 503 is connected to a second discharge box 401 below. A translation module 5 is fixedly arranged on the base 103. The drive end of the translation module 5 is connected to the discharge... Plate 501 is fixedly connected; it can be explained that when the transmission module 2 of this embodiment is conveying materials, the grains are first discharged into the collection hopper 301 along the discharge port 204. In the initial state, the discharge plate 501 is in a closed state to the discharge port 302, and the grains in the collection hopper 301 cannot be discharged. In this embodiment, the discharge plate 501 can be driven to move horizontally by the translation module 5. When the first receiving interface 502 moves to be connected to the discharge port 302, the grains can be discharged into the first discharge box 402 through the first receiving interface 502. When the second receiving interface 503 is connected to the discharge port 302, the grains can be discharged into the second discharge box 401 through the second receiving interface 503. Based on this, this embodiment can achieve the effect of alternately discharging grains into the filling bag by pre-placing the filling bag under the first discharge box 402 or the second discharge box 401, thereby improving the filling efficiency.

[0028] As one implementation method of this embodiment, in order to achieve the effect of quantitative filling of filling bags of different capacities, please refer to... Figures 3-7Both the first discharge box 402 and the second discharge box 401 are slidably fitted with an extension box 7 at their bottoms. The extension box 7 has a material discharge port 709 at its bottom. The extension box 7 is connected to a lifting module that drives it to rise and fall. It can be noted that in this embodiment, when filling bags of different capacities, the lifting module can drive the extension box 7 to rise and fall outside the discharge box. Accordingly, when filling small-capacity bags, the lifting module drives the extension box 7 to rise, and when filling large-capacity bags, the lifting module drives the extension box 7 to fall, thereby achieving the effect of changing the volume of the discharge box.

[0029] In addition, you can refer to Figures 1-5 In this embodiment, the outer walls of the first discharge box 402 and the second discharge box 401 are also provided with scale lines 403; specifically, by setting the scale lines 403, when the lifting module drives the expansion box 7 to lift, the internal capacity of the discharge box of the expansion box 7 in this state can be read.

[0030] Specifically, the lifting module includes a first screw 802 rotatably disposed at the bottom of the collecting hopper 301. The bottom of the first screw 802 is fixedly connected to the output end of the drive motor 8. A first nut 803 is spirally sleeved on the first screw 802. The two ends of the first nut 803 are fixedly connected to the first discharge box 402 and the second discharge box 401 respectively through the lifting frame 804. It can be noted that in this embodiment, when adjusting the lifting of the expansion box 7, the drive motor 8 can be started to drive the first screw 802 to rotate. During the lifting and lowering process of the first nut 803 on the first screw 802, the expansion box 7 can be driven to lift and lower through the lifting frame 804 to achieve the effect of adjusting the capacity of the discharge box.

[0031] Please refer to Figures 6-9To secure the material bag to the discharge port 709, in this embodiment, clamping plates 706 are symmetrically arranged on both sides of the discharge port 709. A sloping groove 707 is formed at the bottom of the clamping plate 706 on one side facing the discharge port 709. Support plates 701 are fixedly arranged on the bottom of both sides of the expansion box 7. A limiting cylinder 702 is slidably inserted into the support plate 701. The clamping plate 706 is fixedly connected to a limiting rod 704 slidably inserted into the limiting cylinder 702. A telescopic spring 705 is provided on the limiting rod 704. One end of the telescopic spring 705 is fixedly connected to the limiting cylinder 702, and the other end is fixedly connected to the clamping plate 706. A guide wheel 708 is rotatably arranged at the end of the limiting rod 704 away from the limiting cylinder 702. Guide plates 504 are also fixedly arranged on both sides below the collecting hopper 301. Inclined guide grooves 505 are respectively opened at both ends of 504, and the two side guide plates 504 are fixedly connected by support frame 506. It can be explained that the two side clamps 706 are in a close fit with the box wall at the discharge port 709 under the elastic force of the telescopic spring 705. When it is necessary to load material, the two ends of the material bag are respectively embedded between the clamps 706 and the discharge port 709 along the inclined groove 707 to achieve the effect of pre-fixation. When the translation module 5 drives any set of discharge boxes to move downwards towards the discharge port 302, based on the limiting effect of the inclined guide groove 505 on the guide wheel 708, the limiting cylinder 702 is pushed to squeeze the telescopic spring 705, and further compressive elastic force is generated to further clamp the bag mouth of the material bag through the clamps 706 to prevent it from falling off during subsequent loading and to ensure stability.

[0032] In this embodiment, when adjusting the lifting and lowering of the expansion box 7, the guide wheel 708 can be lifted and lowered synchronously. In order to ensure that the guide plates 504 on both sides always abut against the guide wheel 708, a support shaft 105 is fixedly arranged on the base 103. A guide seat 507 fixedly connected to one side guide plate 504 is slidably sleeved on the support shaft 105. U-shaped plates 509 are fixedly arranged on one side of the two sets of expansion boxes 7, and the guide plate 504 on one side is slidably embedded in the U-shaped plate 509. It can be noted that during the lifting and lowering process of the expansion box 7 in this embodiment, the guide plate 504 can be lifted and lowered synchronously through the U-shaped plate 509. The guide plate 504 synchronously drives the guide seat 507 to slide on the support shaft 104 to achieve the effect of guiding and limiting, and ensure its operational stability. Correspondingly, since the U-shaped plate 509 can slide on the guide plate 504, no interference will occur when the translation module 5 drives the two expansion boxes 7 to translate.

[0033] Furthermore, the translation module 5 in this embodiment can adopt a synchronous belt drive structure, which is fixed to the top of the support shaft 105. This embodiment does not limit its specific model and structure, as long as it meets the actual application requirements.

[0034] Example 2 It is understandable that in Embodiment 1, after the grains are fed into the bag, the two side clamps 706 cannot bear the weight of the grains due to their own weight, and slippage is likely to occur.

[0035] like Figures 2-7 As shown, in order to solve the above problems, a support plate 6 is provided below the first discharge box 402 and the second discharge box 401 respectively. A first baffle 603 is fixedly provided on the side of the support plate 6 facing the base 103, and a second baffle 602 is fixedly provided on both sides of the support plate 6 respectively. A third baffle 604 is provided on the side of the support plate 6 away from the first baffle 603.

[0036] The working principle of this embodiment is as follows: In this embodiment, the supporting plate 6 is set so that the filling bag can be supported by the supporting plate 6 during the bagging process, and at the same time, the baffle is set to limit the filling bag.

[0037] It should be emphasized that the core improvement of this embodiment is that by setting the bearing plate 6 and the baffle, the material bag can be limited and supported to ensure the stability of the filling.

[0038] It should be noted that the third baffle 604 is slidably arranged at the end of the bearing plate 6, and a support cylinder 605 is fixedly arranged between the two bearing plates 6. Positioning rods 606 are slidably inserted into both ends of the support cylinder 605, and the other end of the positioning rods 606 is fixedly connected to the third baffle 604. A return spring 607 is provided on the positioning rods 606, one end of which is fixedly connected to the support cylinder 605, and the other end is fixedly connected to one side of the third baffle 604. The two ends of the support frame 506 are respectively... A baffle 508 is fixedly installed to limit the third baffle 604. It can be explained that after the filling bag is filled, as the translation module 5 drives it to move to one side, the third baffle 604 can abut against the baffle 508. Under the abutment action, the baffle 508 shifts to one side so that the workers can unload the filling bag. During this process, the third baffle 604 can squeeze the positioning rod 606 and compress the return spring 607 to generate elastic force, so as to drive the subsequent components to reset.

[0039] like Figure 2 -to Figure 7In this embodiment, when using a smaller capacity bag, due to the smaller height of the bag, a second screw 806 is rotatably mounted on one side of the first screw 802 to ensure that the supporting plate 6 can still support it. A first gear 801 is fixedly mounted on the first screw 802, and a second gear 805 meshing with it is fixedly mounted on the second screw 806. The gear ratio of the first gear 801 to the second gear 805 is 2:1. A second nut 807 is screwed onto the second screw 806, and the second nut 807 is fixedly connected to the supporting plates 6 on both sides through the lifting frame 601. It can be noted that in this embodiment... When the drive motor 8 rotates, it can synchronously drive the first gear 801 to rotate. The first gear 801 drives the second screw 806 to rotate by meshing with the second gear 805. During the movement of the second nut 807 on the second screw 806, the lifting frame 601 can synchronously drive the two side bearing plates 6 to rise and fall. Since the thread structure of the first screw 802 and the second screw 806 is exactly the same, when the first gear 801 drives the second gear 805 to rotate, the second nut 807 rises and falls at a faster rate than the first nut 803. This allows the bearing plate 6 to carry bags of different heights, making it more adaptable.

[0040] The basic principles, main features, and advantages of this application have been described above. Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this application. Various changes and modifications can be made to this application without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed application.
