Description

Technical Field

[0001] This utility model relates to the field of sowing equipment technology, specifically a vegetable seed planter. Background Technology

[0002] my country has a vast vegetable cultivation scale, which is mainly divided into two categories according to its use: one type is harvested before entering the reproductive growth stage for consumption; the other type is harvested after the plant completes its growth cycle for seed propagation or oil processing. In modern agricultural planting systems, mechanized sowing of vegetable seeds is quite common, and choosing the right sowing equipment is crucial.

[0003] For example, CN207802733U discloses an agricultural seeder, including a seeder support frame. One side of the seeder support frame is rotatably connected to a seeder moving wheel via a rotating shaft, and the other side of the seeder support frame is rotatably connected to a seeder drive wheel via a rotating shaft. A drive chain protective cover is bolted to the front surface of the seeder support frame. A seeder handle branch is bolted to one end of the upper surface of the seeder support frame. A scraper connecting rod is welded to one side of the seeder handle branch, and a moving wheel scraper is bolted to the scraper connecting rod. A non-woven fabric seed storage box is provided on the other side of the seeder handle branch. By designing a non-woven fabric seed storage box installed above the seed box of the seeder, it is easier to ensure the ventilation of the seeds, which solves the problem that the seed storage boxes of existing agricultural seeders are made of non-breathable materials, which makes them prone to damage under sunlight.

[0004] However, the above-mentioned agricultural seeder has the following problems: First, it requires manual pushing during sowing, which is time-consuming and labor-intensive, and is not suitable for large-scale planting; second, it can only sow one row of seeds at a time, which is inefficient; third, it cannot adjust the amount of seeds fed and the row spacing, which makes it unsuitable for large-scale planting. Utility Model Content

[0005] This utility model provides a vegetable seed planter to solve the problems mentioned in the background art of an agricultural planter, which require manual pushing during sowing, are time-consuming and labor-intensive, are not suitable for large-scale planting, can only sow one row of seeds at a time, are inefficient, and have poor applicability due to the inability to adjust the seed feed and row spacing.

[0006] To address the existing problems, this utility model provides a vegetable seed planter, comprising two parallel side beams, a support rod fixedly connected to one side of each side beam, an auxiliary wheel rotatably connected to the lower end of the support rod, one end of each side beam fixedly connected to a connecting beam, a traction connecting assembly provided on the connecting beam, and two guide rods fixedly connected between the two side beams, with several planting components provided on the guide rods.

[0007] Specifically, the traction connection assembly includes two connecting lugs and two extension blocks that are fixedly connected to the front and rear surfaces of the connecting beam, respectively. The extension blocks are fixedly connected to the lower end of the support arm, and the upper end of the support arm is fixedly connected to the connecting lugs.

A mounting frame is fixedly connected to one end of the feeding cylinder near feeding roller a, and a drive motor is mounted on the mounting frame. The output shaft of the drive motor is fixedly connected to feeding roller a. A material holding box is fixedly connected to the upper surface of the feeding cylinder, and a feeding pipe is fixedly connected to the lower surface of the feeding cylinder. The lower end of the feeding pipe is connected to sowing teeth.

[0009] Furthermore, the seeding assembly also includes a connecting arm fixedly connected to the front and rear surfaces of the material container. A sleeve is fixedly connected to the end of the connecting arm away from the material container. The sleeve is slidably connected to the guide rod. A nut is fixedly connected to the wall of the sleeve, and a clamping screw is provided on the nut.

[0010] Furthermore, one side of the feeding roller a is provided with a plug-in post, and one side of the feeding roller b is provided with a plug-in groove that matches the plug-in post.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. By setting up a connecting component, this utility model can connect a vegetable seed planter to the rear of a tractor, and the tractor can drive the vegetable seed planter forward, which improves production efficiency compared with existing equipment.

[0015] 2. This utility model, by setting up a sowing component, allows for the loosening of the locking nut on the clamping screw according to the row spacing requirements, thereby releasing the clamping constraint of the screw on the guide rod. At this time, the sowing component is pushed laterally, which allows the sleeve of the sowing component fitted on the guide rod to achieve axial displacement. After the spacing between each sowing component is adjusted to the target row spacing, the locking screw is tightened so that its lower end presses tightly against the surface of the guide rod, thus achieving reliable fixation between the sowing component and the guide rod, thereby realizing the adjustment of the planting row spacing.

[0016] 3. Before sowing, this utility model allows for the selection of feeding rollers b corresponding to different capacity specifications of the receiving trough b according to actual planting needs. By assembling the receiving trough b of the feeding roller b with the receiving trough a, coordinated seed supply is achieved. Based on the fixed volume characteristics of the receiving trough a, by replacing the feeding rollers b with different capacity receiving troughs b and forming a combined cavity structure, the unit sowing amount of vegetable seeds is controlled.

[0028] The sowing assembly 7 includes a feeding cylinder 701. The upper and lower cylinder walls of the feeding cylinder 701 are respectively provided with a feed inlet 702 and a discharge outlet 703. Feeding rollers a704 and b705 are rotatably connected inside the feeding cylinder 701. Feeding rollers a704 and b705 are connected by a fastening screw 706. A mounting frame 707 is fixedly connected to one end of the feeding cylinder 701 near the feeding roller a704. A drive motor 708 is mounted on the mounting frame 707. The output shaft of the drive motor 708 is fixedly connected to the feeding roller a704. A material holding box 709 is fixedly connected to the upper surface of the feeding cylinder 701. A feeding pipe 710 is fixedly connected to the lower surface of the feeding cylinder 701. The lower end of the feeding pipe 710 is connected to a sowing tooth 711.

[0029] The seeding assembly 7 also includes a connecting arm 712 that is fixedly connected to the front and rear surfaces of the material container 709. A sleeve 713 is fixedly connected to one end of the connecting arm 712 away from the material container 709. The sleeve 713 is slidably connected to the guide rod 6. A nut 714 is fixedly connected to the wall of the sleeve 713. A clamping screw 715 is provided on the nut 714.

[0030] Among them, the feeding roller a704 has a plug-in post 7041 on one side end, and the feeding roller b705 has a plug-in groove 7051 on one side end that is compatible with the plug-in post 7041.

[0031] Among them, receiving grooves a7042 and receiving groove b7052 are respectively opened on the outer wall of the side end where the feeding rollers a704 and b705 contact.

[0032] refer to Figures 4 to 7 The above technical solution allows for the selection of feeding rollers b705 with different capacity specifications for the receiving trough b7052 according to actual planting needs. By assembling the receiving trough b7052 of the feeding roller b705 with the receiving trough a7042 of the feeding roller a704, coordinated seed supply is achieved. Based on the fixed volume characteristic of the receiving trough a7042, by replacing the feeding rollers b705 with different capacity receiving troughs b7052 and forming a combined cavity structure, the unit sowing rate of vegetable seeds can be controlled.

[0033] Among them, the feed roller b705 has a through hole b7053 on its axis, and the feed roller a704 and the plug post 7041 have a through hole a7043 on their axes. The inner walls of the through holes b7053 and a7043 are provided with internal threads that are compatible with the fastening screw 706.

[0034] Working principle:

[0035] Preliminary debugging: Connect the connecting ears a501 and b504 of the traction connecting assembly 5 to the tractor traction device. After completing the traction assembly of the seeder, inject vegetable seeds into the feeding box 709, and connect the drive motor 708 to the tractor control device via a control cable, with power provided by the tractor battery. When adjusting the row spacing, first loosen the clamping screw 715 inside the nut 714 to release the clamping state on the guide rod 6. At this time, the sleeve 713 of the sowing assembly 7 can slide freely in the axial direction of the guide rod 6. After the spacing between each sowing assembly 7 is adjusted to the row spacing required for agronomic planting, rotate the clamping screw 715 in the opposite direction so that its end presses against the guide rod 6, thereby fixing the sowing assembly 7 to the guide rod 6 and thus realizing the adjustment of the planting row spacing. Next, loosen the fastening screw 706, remove the installed feeding roller b705 from the feeding cylinder 701, replace it with the feeding roller b705 corresponding to the matching specification groove b7052, and tighten the fastening screw 706 so that the insertion groove 7051 of the feeding roller b705 and the insertion post 7041 of the feeding roller a704 form a tenon joint. At this time, the groove b7052 and the groove a7042 form a metering cavity, which allows for the adjustment of the seeding amount and ensures that the seeding amount meets the planting requirements.

[0036] During sowing operations, the tractor pulls the seeder at a constant speed. The drive motor 708 is started by the control switch in the cab. Its output shaft drives the feeding roller a704 and the driven feeding roller b705 to rotate synchronously. The metering chamber composed of the trough a7042 and the trough b7052 continuously extracts the seeds from the material box 709 and guides them into the sowing teeth through the feeding pipe 710 to complete precision sowing.

[0037] It should be noted that: under the constant traction speed of the tractor, the seed dispensing frequency per unit time can be changed by adjusting the speed of the drive motor 704, thereby realizing the control of the sowing plant spacing.
