Abstract
Apparatus and methods for picking and coring produce heads. A righting mechanism receives and orients planted produce heads, and when a planted head is in a position to be severed, a lift arm and clamp wheel are controlled to position a clamp proximal to the planted head, wherein the planted head is clamped and a severing mechanism severs the planted head from the soil bed. The lift arm and clamp wheel operate to automatically reposition the clamped and severed head proximal to a coring mechanism, and the coring mechanism automatically removes the core of the clamped and severed head.
Claims21
An apparatus for picking and coring produce heads, comprising:
- a chassis;
- a rotating clamp wheel having one or more clamps, each configured to hold a produce head;
- a lift arm that couples the clamp wheel with the chassis, wherein the lift arm is configured to controllably raise and lower the clamp wheel;
- a righting mechanism configured to position a planted produce head in a vertical orientation;
- a trigger mechanism that detects when a planted head is in a position to be severed;
- a severing mechanism configured to sever a planted produce head from a soil bed;
- and
- a coring mechanism configured to remove a core of a clamped produce head;
- wherein in operation, as the apparatus travels along a soil bed, the righting mechanism receives and orients planted produce heads, wherein when a planted head is in the position to be severed, the lift arm and clamp wheel are controlled to position a clamp proximal to the planted head, wherein the planted head is clamped and the severing mechanism severs the planted head from the soil bed, wherein the lift arm and clamp wheel re-position the clamped and severed head proximal to the coring mechanism, and wherein the coring mechanism automatically removes the core of the clamped and severed head.
A method of automatically picking and coring produce heads with a picking and coring apparatus configured to travel along a soil bed containing planted produce heads, the method comprising:
- receiving a produce head in a pair of righting screws configured to hold the produce head in a vertical orientation;
- detecting when the produce head is in a desired location;
- and thereafter automatically:
- clamping the produce head when the head is in the desired location;
- severing the produce head when the head is in the desired location;
- re-positioning the clamped produce head proximal to a coring mechanism;
- removing the core of the clamped produce head with the coring mechanism;
- re-positioning the clamped and cored produce head proximal to a drop station;
- and
- releasing the cored produce head.
