Description

Technical Field

[0001] The invention relates to a rotary torreya green fruit peel grater. Background Art

[0002] Torreya grandis is a beloved nut, but processing it is complex, particularly peeling the green husk. Currently, peeling is done manually, which is inefficient and costly. This is especially true when purchasing large quantities of nut. Manual peeling is too slow, leading to the nuts rotting and being discarded.

[0003] In order to improve the peeling efficiency of Torreya grandis, semi-automatic Torreya grandis peelers are available on the market. However, this type of peeler has defects: during the impact peeling process, the disordered impact force will damage the eyes of the Torreya grandis, causing the Torreya grandis kernels to be eroded by decay bacteria during the composting process, affecting the flavor and quality of the Torreya grandis, and even the toxic substances in it will affect human health.

[0004] The utility model patent application number 202220954104.6 discloses a "Chinese torreya peeling mechanism", which uses a pair of parallel peeling rollers to squeeze and peel the Chinese torreya fruit. The spacing between the peeling rollers is larger than the size of the kernel and smaller than the size of the Chinese torreya fruit. This structure of the Chinese torreya peeling mechanism still has the following defects: First, the spacing of its peeling rollers is not suitable for larger or smaller Chinese torreya fruit. The kernels of larger Chinese torreya fruit will be crushed by the peeling rollers, and the green skin of smaller Chinese torreya fruit cannot be peeled off by the peeling rollers; second, the peeling of the Chinese torreya fruit by squeezing the peeling rollers not only causes greater or lesser damage to the kernels, but also does not peel cleanly; third, it can only be used for Chinese torreya fruit whose skin is already ripe, and is not suitable for Chinese torreya fruit whose green skin is tightly adhered to the kernel. Summary of the Invention

[0005] The purpose of the present invention is to provide a rotary torreya fruit peel grater, which is suitable for grating the peel of immature torreya fruit, especially for torreya fruit with the peel and kernel tightly adhered, and is also suitable for grating the peel of mature torreya fruit. In particular, the rotary torreya fruit peel grater of the present invention is used to rub the peel of torreya fruit; the kernel of the torreya fruit will not be broken, and it is beneficial to protect the eyes at both ends of the torreya fruit, ensure the integrity of the torreya kernel, and facilitate late fermentation; thus, continuous and fully automatic peeling of torreya fruit is achieved.

The right and left rear lifting gears are respectively arranged on both sides of the rear centering lifting rack and are meshed with the rear centering lifting rack, and the left and right front lifting gears are respectively arranged on both sides of the front centering lifting rack and are meshed with the front centering lifting rack.

[0013] The rotary disc is divided into a receiving area, a middle skin rubbing area, a lower skin rubbing area, an upper skin rubbing area, a retreat area, a discharging area and a reset adjustment area in a counterclockwise direction starting from the discharger position. A skin residue collecting trough is provided below the middle skin rubbing area, the lower skin rubbing area and the upper skin rubbing area of ​​the rotary disc. A skin residue discharger is provided at the lower part of the skin residue collecting trough. A torreya grandis collecting trough is provided below the discharging area of ​​the rotary disc. A torreya grandis discharger is provided at the bottom of the torreya grandis collecting trough. In the receiving area: the torreya grandis in the silo enters the distributing device through the discharger, and the distributing device sends a single upright torreya grandis into the torreya grandis clamping and rotating device. The upper pressure head and the lower pressure head clamp the torreya grandis, and the rotary gear drives the rotary main shaft to rotate. And drive the rotary disk to rotate; in the middle section skin rubbing area: the rotating rotary disk sends the ginkgo nuts into the middle section skin rubbing area, and the ginkgo nuts flexible skin rubbing device moves forward under the action of the feed drive assembly. At the same time, the ginkgo nuts rotate under the action of the drive gear, and the rotating skin grater contacts the rotating ginkgo nuts to complete the skin rubbing of the middle section of the ginkgo nuts. After completing the skin rubbing of the middle section, the ginkgo nuts flexible skin rubbing device retreats backward under the action of the feed drive assembly, and the skin residue of the ginkgo nuts is sent out of the machine through the skin residue collecting trough and the skin residue discharger; in the lower section skin rubbing area: the rotating rotary disk sends the ginkgo nuts into the lower section skin rubbing area, and the centering lifting assembly moves downward, so that the ginkgo nuts flexible skin rubbing device is obliquely aimed at the lower section of the ginkgo nuts. The flexible skin grating device for ginkgo nuts moves toward the lower section of the ginkgo nuts under the action of the feed drive assembly. At the same time, the ginkgo nuts rotate under the action of the drive gear, and the rotating skin grater contacts the rotating ginkgo nuts to complete the skin grating of the lower section of the ginkgo nuts. After completing the skin grating of the lower section, the flexible skin grating device for ginkgo nuts retreats backward under the action of the feed drive assembly, and the skin residue of the ginkgo nuts is sent out of the machine through the skin residue collecting trough and the skin residue discharger; in the upper skin grating area: the rotating turntable sends the ginkgo nuts into the upper skin grating area, and the centering lifting assembly moves upward. At the same time, the skin grating wheel support seat rotates 180 degrees under the action of the skin grating reversing assembly. Subsequently, the flexible skin grating device for ginkgo nuts moves forward under the action of the feed drive assembly. At the same time, the ginkgo nuts rotate under the action of the driving gear, and the rotating peel grater contacts the rotating ginkgo nuts to complete the peeling of the upper part of the ginkgo nuts, and the peel residue of the ginkgo nuts is sent out of the machine through the peel residue collecting trough and the peel residue discharger; in the retreat area: the rotating turntable sends the ginkgo nuts into the retreat area, and the lifting cam drives the vertical rod of the rotating disk to move upward, and finally drives the upper pressure head to move upward. At the same time, the steering support shaft fixed on the vertical rod of the rotating disk slides in the inclined groove of the base, so that the rotating disk of the upper pressure head rotates a preset angle, so that the center of the upper pressure head and the center of the guide locator are separated, so that the upper end of the ginkgo nuts becomes free and can be discharged, and also makes it possible for the next ginkgo nuts to enter smoothly in this state;In the discharge area: The rotating turntable feeds the ginkgo nuts into the discharge area. At this point, the upper pressure head separates from the upper end of the ginkgo nuts, and the guide positioner rotates a preset angle to allow the ginkgo nuts to slide out in an inclined state. The ginkgo nuts are then sent out of the machine through the ginkgo nut collection trough and the ginkgo nut discharger. In the reset and adjustment area: The rotating turntable feeds the discharged ginkgo nuts through the clamping and rotating device into the reset and adjustment area. The guide positioner returns to its original position, and the cleaning device removes the residue from the previous ginkgo nut. Waiting for the next ginkgo nut to enter, the above steps are repeated after entering the receiving area.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: due to the adoption of the above technical solution, the rotary ginkgo nut peeling machine is evenly distributed with a plurality of ginkgo nut peeling devices around the edge of its rotary disk, and the material dividing device can automatically and sequentially feed the ginkgo nuts to be peeled into each ginkgo nut clamping and rotating device, and the ginkgo nut clamping and rotating device can circumferentially protect the ginkgo nuts and keep them upright and rotated in the initial state, and the peeler of the ginkgo nut flexible peeling device is driven to rotate by the pulley driving mechanism to wipe off the ginkgo nuts. The green skin on the periphery of the fruit is scraped off by this structure, which uses rotary friction to scrape off the green skin of the Torreya grandis, thus avoiding the defect of crushing the Torreya grandis kernel. It is suitable for scraping the skin of immature Torreya grandis, especially for Torreya grandis whose green skin and kernel are tightly adhered. It is also suitable for scraping the skin of mature Torreya grandis. Since the upper and lower skins of the Torreya grandis are pressed by the upper and lower pressure heads respectively, the scraper will not scrape off the upper and lower skins, which protects the eyes at both ends of the Torreya grandis perfectly, ensures the integrity of the Torreya grandis kernel, and is beneficial to the later fermentation of Torreya grandis.

[0015] A further beneficial effect is that the peel scraper has the feed drive assembly, peel scraping reversing assembly and centering lifting assembly, which can flexibly control the peel scraping feed amount and peel scraping angle of the peel scraper, further improving the peel scraping effect; the setting of the first and second double buffer pads can control the pressure applied to the ginkgo nuts when the peel scraper is scraping the skin so that it is not too large. When the pressure is too large, the first and second buffer pads can absorb the displacement caused by the retreat of the ginkgo nuts flexible peel scraping device through double deformation, thereby better protecting the ginkgo nuts from being scratched by the peel scraper.
