Description

Technical Field

[0001] This utility model relates to the technical field of tobacco field management equipment, and in particular to a tobacco field ridging and fertilization machine. Background Technology

[0002] With the development of modern tobacco agriculture, mechanized technology for the entire tobacco production process has been extended to all stages of tobacco production. Ridging and fertilization in tobacco fields are the foundation of tobacco planting and a crucial step in harvesting high-quality tobacco leaves. Mechanized ridge-raising and fertilization have been largely achieved in tobacco planting in my country. After ridge-raising, the next step is digging holes and transplanting. Existing agricultural machinery includes integrated equipment, such as the machinery described in publication number CN208908540U, which includes a drive shaft assembly, a rotary tiller assembly, a frame assembly, left and right ridge-raising plowshares, a shaping device, a hole-digging mechanism, and a fertilization mechanism assembly. The output end of the drive shaft assembly is connected to the input shaft of the rotary tiller assembly's transmission box. The rotary tiller assembly is connected to the tractor's rear upper and lower tie rods via a three-point suspension system using pins. The front end of the frame assembly is fixed to the rear crossbeam of the rotary tiller assembly frame using U-bolts. The left and right ridge-raising plowshares are respectively mounted on the frame assembly. On the lower left and right sides, the shaping device is fixed to the lower rear end of the frame assembly, the hole-digging mechanism is located at the rear of the frame assembly, and the fertilization mechanism assembly is fixed to the top of the frame assembly through the fertilizer box connecting bolt. Ridging, fertilization, and hole digging are completed in one go, which improves labor efficiency and reduces labor intensity. Moreover, the hole depth and plant spacing are uniform and adjustable. With the advent of scientific fertilization, the above-mentioned integrated fertilization machine mixes fertilizer with soil when fertilizing. This fertilization method cannot achieve root hole fertilization and requires a large amount of fertilizer to meet the growth needs of tobacco plants.

Several straight plates 632 are evenly installed on the outer edge of the rotating wheel 631, and a curved plate 633 is fixedly provided at one end of the several straight plates 632 away from the rotating wheel 631. The adjustment mechanism 7 includes a U-shaped frame 71 rotatably mounted on the two shaping devices 5. Connecting rods 72 are symmetrically hinged on the U-shaped frame 71. One end of the connecting rod 72 away from the U-shaped frame 71 is hinged to the corresponding rectangular frame 61. A transmission frame 73 is connected to the U-shaped frame 71. A telescopic adjustment rod 74 is hinged to the frame assembly 1. The telescopic end of the telescopic adjustment rod 74 is hinged to the transmission frame 73.

[0017] It is worth noting that the specific composition of the frame assembly 1, drive shaft assembly 2, rotary tiller assembly 3, ridging plow 4, and shaping device 5 here follows the drive shaft assembly, rotary tiller assembly, frame assembly, left and right ridging plows, and shaping device in publication number CN208908540U. The specific installation method and working principle will not be described in detail here.

[0018] It should be noted that during use, the telescopic adjustment rod 74 of the adjustment mechanism 7 is used to pull the U-shaped frame 71 around the shaping frame 5 by the transmission frame 73 to rotate. During rotation, the connecting rod 72 is used to pull the rectangular frame 61 to rotate, thereby adjusting the opening depth of the hole opening component 63. When the rotating shaft 62 moves with the agricultural machinery, the hole opening component 63 drives the rotating wheel 631 to drive the curved plate 633 at the bottom of the straight plate 632 to open the hole. At the same time, the rotating shaft 62 is connected to the fertilizer dispensing component 68 for transmission. In this way, the fertilizer is poured from the feed port of the hopper cover 67 into the storage hopper 66. Then, the fertilizer dispensing component 68 is used to discharge the fertilizer from the bottom of the fertilizer pipe 65 into the opened hole, so as to achieve precise hole-fed fertilization. In this embodiment, a feed inlet is provided on one side of the hopper cover 67.

[0019] It should also be noted that the telescopic adjustment rod 74 can be a hydraulic rod or an electric telescopic rod, and its extension and retraction can be controlled by adding a corresponding control device.

[0020] In the embodiments of this utility model, please refer to Figures 1 to 6 The fertilizer dispensing assembly 68 includes a rotating rod 681, which is rotatably mounted on the hopper cover 67. The bottom end of the rotating rod 681 extends into the fertilizer pipe 65, and a conical sealing block 682 is fixedly mounted on the bottom end of the rotating rod 681. A notch is provided on one side of the conical sealing block 682. A sealing block 683 that contacts and cooperates with the conical sealing block 682 is fixedly mounted on the bottom end of the fertilizer pipe 65. A plurality of discharge holes 601 are evenly opened on the sealing block 683, which are aligned with the notch of the conical sealing block 682. A transmission rod 684 is rotatably mounted on the hopper cover 67. The transmission rod 684 is connected to the rotating rod 681 through gear transmission, and the transmission rod 684 is connected to the rotating shaft 62 through belt transmission. A first spiral blade 685 and a second spiral blade 686 are fixedly installed on the transmission rod 684 above the conical sealing block 682. The first spiral blade 685 is disposed in the fertilizer pipe 65, and the second spiral blade 686 is disposed in the storage hopper 66. It should be noted that when the fertilizer dispensing assembly 68 is in use, the rotating shaft 62 rotates, and the transmission rod 684 is driven to rotate by belt drive. The transmission rod 684 drives the rotating rod 681 to rotate by gear. When the rotating rod 681 rotates, it drives the first spiral blade 685 and the second spiral blade 686 to rotate synchronously, moving the fertilizer in the storage hopper 66 to the fertilizer dispensing pipe 65. The fertilizer falling into the fertilizer dispensing pipe 65 is sealed by the conical sealing block 682. When the notch in the conical sealing block 682 is opened... After being aligned with the discharge hole 601, the fertilizer is discharged from the discharge hole 601. Under the action of the spacer plate 64, the distance between the fertilizer tube 65 and the rotating shaft 62 is equal to the distance between the opening holes, and the opening holes and fertilization frequency are kept synchronous (here, when one of the curved plates 633 of the opening hole assembly 63 opens a hole, the notch of the conical sealing block 682 is adjusted to align with the discharge hole 601 of the sealing block 683, so as to synchronously and equally distance the fertilizer is applied to the opening holes). The fertilizer falls into the opened smoke hole, completing the precise application of fertilizer to the opening holes. In this embodiment, the gear transmission ratio between the transmission rod 684 and the rotating rod 681 is one, which makes it easy for the opening assembly 63 to open the holes and the fertilization of the discharge hole 601 to maintain the same frequency.

[0021] The working principle of the tobacco field ridging and fertilizing machine provided by this utility model is as follows: In use, the telescopic adjustment rod 74 of the adjustment mechanism 7 is used to pull the U-shaped frame 71 around the shaping frame 5 by the transmission frame 73 to rotate. When rotating, the connecting rod 72 is used to pull the rectangular frame 61 to rotate, thereby adjusting the opening depth of the hole opening component 63. When the rotating shaft 62 moves with the agricultural machinery, the hole opening component 63 drives the rotating wheel 631 to drive the curved plate 633 at the bottom of the straight plate 632 to open the hole. At the same time, the rotating shaft 62 is connected to the fertilizer dispensing component 68 for transmission. In this way, the fertilizer is poured from the feed port of the hopper cover 67 into the storage hopper 66. Then, the fertilizer dispensing component 68 is used to discharge the fertilizer from the bottom of the fertilizer pipe 65 into the opened hole, so as to achieve precise hole-fed fertilization. Specifically, when the fertilizer dispensing assembly 68 is in use, the rotating shaft 62 rotates, and the transmission rod 684 is driven to rotate by belt drive. The transmission rod 684 drives the rotating rod 681 to rotate by gear. When the rotating rod 681 rotates, it drives the first spiral blade 685 and the second spiral blade 686 to rotate synchronously, moving the fertilizer in the storage hopper 66 to the fertilizer dispensing pipe 65. The fertilizer falling into the fertilizer dispensing pipe 65 is sealed by the conical sealing block 682. When the notch in the conical sealing block 682 is opened and the fertilizer is dispensed... After the feed holes 601 are aligned, the fertilizer is discharged from the discharge hole 601. Under the action of the spacer plate 64, the distance between the fertilizer application tube 65 and the rotating shaft 62 is equal to the distance between the opening holes, and the opening holes and fertilization frequency are kept synchronous (here, when one of the curved plates 633 of the opening hole component 63 opens a hole, the notch of the conical sealing block 682 is adjusted to align with the discharge hole 601 of the sealing block 683, so as to synchronously and equally space the fertilization in the opening holes). The fertilizer falls into the opened smoke hole, completing the precise fertilization in the opening holes.
