Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and shown in the accompanying drawings here can be arranged and designed in various different configurations.

[0029] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the present invention.

[0030] Figure 1-9 A specific embodiment of the present invention is a forage drying and storage device, such as Figure 1-4 As shown, a feed port 105 is provided at one end of the upper portion of the drying and molding bin 1, and a discharge port is provided at one side of the bottom connected to the storage bin 2. The grass enters the storage bin 2 from the feed port 105. During this process, the grass passes through a stirring device 6, a secondary hot air drying device 7 and a molding mechanism 8 in sequence. The molding mechanism 8 compacts the grass into blocks on the drying tray 4, and sends the blocks to the storage bin 2 together with the drying tray 4. A moisture-proof mechanism is provided on the drying tray 4.

[0031] like Figure 4As shown, the drying and molding bin 1 is a rectangular bin body, with a feed inlet 105 on the left side of the top, a vent on the right side of the top and covered with an exhaust screen 106, the drying and molding bin 1 is divided into three layers from top to bottom, each layer is separated by a conveyor belt, the first conveyor belt 107 on the top layer receives the falling grass and transports it to the right side to fall, the second conveyor belt 108 on the middle layer transports the grass to the molding mechanism 8 on the left, the molding mechanism 8 compacts the grass into blocks on the drying tray 4, and is transported to the storage bin 2 by the third conveyor belt 109 on the bottom layer.

[0032] like Figure 4 As shown, a rotating motor 601 of a dispersing device 6 is installed on the right side wall above the first conveyor belt 107 in the drying and molding bin 1. The motor shaft of the rotating motor 601 is transmission-connected to a dispersing rod 602 fixed above the first conveyor belt 107 through a bearing. The dispersing rod 602 is of a corrugated structure. A plurality of electric heating wires are provided on the inner wall of the drying and molding bin 1. The dispersing rod 602 can disperse the grass conveyed on the first conveyor belt 107, so as to facilitate the drying of the grass from the inside to the outside.

[0033] like Figure 4 As shown, a secondary hot air drying device 7 is provided just below the exhaust screen 106, and the secondary hot air drying device 7 is located above the second conveyor belt 108, and includes a hot air blower 701 installed on the right side wall of the drying and forming bin 1, and the air outlet of the hot air blower 701 is connected to the hot air pipe 702, and the air outlet of the hot air pipe 702 is upwardly arranged and provided with a screen, which is used to perform secondary hot air drying on the falling grass. The air volume of the hot air blower is adjusted to avoid blowing the grass out from the feed inlet.

[0034] like Figure 4 Figure 5 Figure 6 As shown, the forming mechanism 8 includes a mounting beam 801 fixedly connected to the front and rear side walls of the drying and forming bin 1, the mounting beam 801 is located below the first conveyor belt 107, and a compacting device is symmetrically arranged at the bottom of the mounting beam 801, including a hydraulic rod 802 fixedly connected below the mounting beam 801, and a compacting plate 803 is hinged at the bottom of the hydraulic rod 802, and one end of a telescopic rod 804 is also hinged on the compacting plate 803, and the other end of the telescopic rod 804 is hinged to the hydraulic rod 802. The horizontal angle of the compacting plate 803 is controlled by changing the length of the telescopic rod 804, and a notch is opened on the inner side of the compacting plate 803, and a top door 805 is installed on the notch through a torsion spring 806. The notch of the two symmetrical compacting plates 803 when they are horizontally closed corresponds to the moisture-proof mechanism of the drying tray 4 below.

[0035] For the forming process, the PLC controller can be used to set the interval time to control the downward pressure, or a sensor can be set on the inner wall to detect the degree of grass accumulation here to control the timing of downward pressure. Figure 5As shown in FIG. 1 , when there is no downward pressure forming, the two compacting plates 803 are tilted and the hydraulic rod 802 is retracted to facilitate the stacking of grass downward. Figure 4 As shown, during the forming process, the two compacting plates 803 are placed horizontally. During the pressing process, the drying square tube 402 on the drying tray 4 will push open the top door 805, and the compacting plates 803 compact the grass on the drying tray 4 into the following shape: Fig. 9 The formed grass block 5 is shown. After compaction is completed, after replacing the new drying tray 4, the telescopic rod 804 is shortened to allow the grass to continue to be piled up here, and the two compacting plates 803 are tilted to shake off some grass received by the upper part of the compacting plates 803 during the compaction process to the bottom.

[0036] like Figure 4 Figure 7 Figure 8 As shown, an electromagnet 110 is installed at the bottom of the drying and forming bin 1 between the first sliding door 101 and the second sliding door 102 as a positioning device, and the positioning device also includes an iron sheet 403 buried in the bottom center of the drying tray 4. It is used to accurately place the drying tray 4 between the first sliding door 101 and the second sliding door 102. The drying tray 4 includes a rectangular tray bottom plate 401 made of nylon, an iron sheet 403 is buried in the bottom center of the rectangular tray bottom plate 401, and an upright drying square tube 402 is fixedly connected to the upper center of the rectangular tray bottom plate 401. The drying square tube 402 is hollow inside and can be taken out and filled with desiccant. The outside of the drying square tube 402 is opened with a plurality of through holes to prevent moisture and absorb moisture from the inside of the forage.

[0037] A transmission belt mechanism and a push rod mechanism are installed in the storage bin 2. Conventional transmission belts and push rods can be used here to push a number of drying trays 4 with formed hay blocks 5, and align the drying trays 4 in the storage bin 2. A discharge door is opened on one side of the storage bin 2, and the drying trays 4 with formed hay blocks 5 can be sent out one by one through the movement of the transmission belt mechanism and the push rod mechanism. The hay drying and storage device is equipped with a conventional PLC controller, which controls and connects all electrical components, and the control also adopts a conventional software control method, which is not within the scope of protection of this application.

[0038] The specific usage of this embodiment is as follows:

[0039] A number of drying trays 4 are transported forward to the left side of the drying and molding bin 1 by the fourth conveyor belt 301, the telescopic cylinder 104 is actuated to open the first sliding door 101 and the second sliding door 102, the pushing cylinder 302 is actuated to deliver a drying tray 4 into the drying and molding bin, at this time, the electromagnet 110 is energized to attract the iron sheet 403 of the drying tray 4 to put the drying tray 4 in place, and then the first sliding door 101 and the second sliding door 102 are closed. The grass enters from the feed port 105 and is driven to the right by the first conveyor belt 107. During the movement, the rotating motor 601 rotates and drives the stirring rod 602 to rotate, so that the grass is evenly dried. After the grass is sent to the right end, it falls and is dried twice by the hot air blowing upwards. Then the grass is transported to the right by the second conveying device and accumulated on the drying tray 4 between the first sliding door 101 and the second sliding door 102. According to the preset time or the sensor detects that the grass has accumulated to a certain extent, the telescopic rod 804 is actuated to keep the two compacting plates 803 horizontal, and the hydraulic rod 802 is extended to compact the grass at the bottom through the compacting plates 803 and press down. During the process, the drying square tube 402 of the drying tray 4 will push open the top door 805. After the compaction and molding is completed, the hydraulic rod 802 retracts. At this time, the compacting plate 803 is kept horizontal first to prevent the grass on the top from falling. Then the first sliding door 101 and the second sliding door 102 are opened synchronously, and the pushing cylinder 302 pushes the next drying tray 4 into place, and pushes the previous drying tray 4 with the molded grass block 5 onto the third conveyor belt 109 and is sent into the storage bin 2. After that, the first sliding door 101 and the second sliding door 102 are closed, and then the telescopic rod 804 is retracted to tilt the compacting plate 803, and shake the grass on it to the bottom to continue to pile up and wait for compaction.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Other modifications or equivalent substitutions made to the technical solution of the present invention by ordinary technicians in the field should be included in the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solution of the present invention.
